core/txpool/blobpool: add cache for GetBlobs request (#35124)

This PR introduces a cache for GetBlobs request.

The main purpose of this PR is to reduce the getBlobs latency by reading and
decoding blobs from the pool in advance of the actual query. This is important
especially in the context of a sparse blobpool, since it may be necessary to
recover blobs from cells on a getBlobs request.

Previously, the Engine API read and decoded blobs from the pool on every call.
Now those calls check the cache and only fall back to the pool on a miss.

The cache has two modes:

- In topK mode (default), it wakes up periodically, picks the most profitable
  pending blob transactions up to the current fork's maxBlobsPerBlock, and loads
  their blobs. The selection logic is shared with the miner's block-building
  logic. The selection size is derived from eip4844.MaxBlobsPerBlock at the
  current head.
- When the CL calls HasBlobs, the cache switches to hasBlobs mode and tries to
  pin the set it just reported as available. Cache updates (read, decode, and
  optionally conversion in the future) run in background goroutines.

+# AGENTS
+
+## Guidelines
+
+- **Keep changes minimal and focused.** Only modify code directly related to the task at hand. Do not refactor unrelated code, rename existing variables or functions for style, or bundle unrelated fixes into the same commit or PR.
+- **Do not add, remove, or update dependencies** unless the task explicitly requires it.
+
+## Pre-Commit Checklist
+
+Before every commit, run **all** of the following checks and ensure they pass:
+
+### 1. Formatting
+
+Before committing, always run `gofmt` and `goimports` on all modified files:
+
+```sh
+gofmt -w <modified files>
+goimports -w <modified files>
+```
+
+### 2. Build All Commands
+
+Verify that all tools compile successfully:
+
+```sh
+make all
+```
+
+This builds all executables under `cmd/`, including `keeper` which has special build requirements.
+
+### 3. Tests
+
+While iterating during development, use `-short` for faster feedback:
+
+```sh
+go run ./build/ci.go test -short
+```
+
+Before committing, run the full test suite **without** `-short` to ensure all tests pass, including the Ethereum execution-spec tests and all state/block test permutations:
+
+```sh
+go run ./build/ci.go test
+```
+
+### 4. Linting
+
+```sh
+go run ./build/ci.go lint
+```
+
+This runs additional style checks. Fix any issues before committing.
+
+### 5. Generated Code
+
+```sh
+go run ./build/ci.go check_generate
+```
+
+Ensures that all generated files (e.g., `gen_*.go`) are up to date. If this fails, first install the required code generators by running `make devtools`, then run the appropriate `go generate` commands and include the updated files in your commit.
+
+### 6. Dependency Hygiene
+
+```sh
+go run ./build/ci.go check_baddeps
+```
+
+Verifies that no forbidden dependencies have been introduced.
+
+## What to include in commits
+
+Do not commit binaries, whether they are produced by the main build or byproducts of investigations.
+
+## Commit Message Format
+
+Commit messages must be prefixed with the package(s) they modify, followed by a short lowercase description:
+
+```
+<package(s)>: description
+```
+
+Examples:
+- `core/vm: fix stack overflow in PUSH instruction`
+- `eth, rpc: make trace configs optional`
+- `cmd/geth: add new flag for sync mode`
+
+Use comma-separated package names when multiple areas are affected. Keep the description concise.
+
+## Pull Request Title Format
+
+PR titles follow the same convention as commit messages:
+
+```
+<list of modified paths>: description
+```
+
+Examples:
+- `core/vm: fix stack overflow in PUSH instruction`
+- `core, eth: add arena allocator support`
+- `cmd/geth, internal/ethapi: refactor transaction args`
+- `trie/archiver: streaming subtree archival to fix OOM`
+
+Use the top-level package paths, comma-separated if multiple areas are affected. Only mention the directories with functional changes, interface changes that trickle all over the codebase should not generate an exhaustive list. The description should be a short, lowercase summary of the change.

-# Clef
-
-Clef can be used to sign transactions and data and is meant as a(n eventual) replacement for Geth's account management. This allows DApps to not depend on Geth's account management. When a DApp wants to sign data (or a transaction), it can send the content to Clef, which will then provide the user with context and ask for permission to sign the content. If the user grants the signing request, Clef will send the signature back to the DApp.
-
-This setup allows a DApp to connect to a remote Ethereum node and send transactions that are locally signed. This can help in situations when a DApp is connected to an untrusted remote Ethereum node, because a local one is not available, not synchronized with the chain, or is a node that has no built-in (or limited) account management.
-
-Clef can run as a daemon on the same machine, off a usb-stick like [USB armory](https://inversepath.com/usbarmory), or even a separate VM in a [QubesOS](https://www.qubes-os.org/) type setup.
-
-Check out the
-
-* [CLI tutorial](tutorial.md) for some concrete examples on how Clef works.
-* [Setup docs](docs/setup.md) for information on how to configure Clef on QubesOS or USB Armory.
-* [Data types](datatypes.md) for details on the communication messages between Clef and an external UI.
-
-## Command line flags
-
-Clef accepts the following command line options:
-
-```
-COMMANDS:
-   init    Initialize the signer, generate secret storage
-   attest  Attest that a js-file is to be used
-   setpw   Store a credential for a keystore file
-   delpw   Remove a credential for a keystore file
-   gendoc  Generate documentation about json-rpc format
-   help    Shows a list of commands or help for one command
-
-GLOBAL OPTIONS:
-   --loglevel value        log level to emit to the screen (default: 4)
-   --keystore value        Directory for the keystore (default: "$HOME/.ethereum/keystore")
-   --configdir value       Directory for Clef configuration (default: "$HOME/.clef")
-   --chainid value         Chain id to use for signing (1=mainnet, 17000=Holesky) (default: 1)
-   --lightkdf              Reduce key-derivation RAM & CPU usage at some expense of KDF strength
-   --nousb                 Disables monitoring for and managing USB hardware wallets
-   --pcscdpath value       Path to the smartcard daemon (pcscd) socket file (default: "/run/pcscd/pcscd.comm")
-   --http.addr value       HTTP-RPC server listening interface (default: "localhost")
-   --http.vhosts value     Comma separated list of virtual hostnames from which to accept requests (server enforced). Accepts '*' wildcard. (default: "localhost")
-   --ipcdisable            Disable the IPC-RPC server
-   --ipcpath               Filename for IPC socket/pipe within the datadir (explicit paths escape it)
-   --http                  Enable the HTTP-RPC server
-   --http.port value       HTTP-RPC server listening port (default: 8550)
-   --signersecret value    A file containing the (encrypted) master seed to encrypt Clef data, e.g. keystore credentials and ruleset hash
-   --4bytedb-custom value  File used for writing new 4byte-identifiers submitted via API (default: "./4byte-custom.json")
-   --auditlog value        File used to emit audit logs. Set to "" to disable (default: "audit.log")
-   --rules value           Path to the rule file to auto-authorize requests with
-   --stdio-ui              Use STDIN/STDOUT as a channel for an external UI. This means that an STDIN/STDOUT is used for RPC-communication with a e.g. a graphical user interface, and can be used when Clef is started by an external process.
-   --stdio-ui-test         Mechanism to test interface between Clef and UI. Requires 'stdio-ui'.
-   --advanced              If enabled, issues warnings instead of rejections for suspicious requests. Default off
-   --suppress-bootwarn     If set, does not show the warning during boot
-   --help, -h              show help
-   --version, -v           print the version
-```
-
-Example:
-
-```
-$ clef -keystore /my/keystore -chainid 4
-```
-
-## Security model
-
-The security model of Clef is as follows:
-
-* One critical component (the Clef binary / daemon) is responsible for handling cryptographic operations: signing, private keys, encryption/decryption of keystore files.
-* Clef has a well-defined 'external' API.
-* The 'external' API is considered UNTRUSTED.
-* Clef also communicates with whatever process that invoked the binary, via stdin/stdout.
-  * This channel is considered 'trusted'. Over this channel, approvals and passwords are communicated.
-
-The general flow for signing a transaction using e.g. Geth is as follows:
-![image](sign_flow.png)
-
-In this case, `geth` would be started with `--signer http://localhost:8550` and would relay requests to `eth.sendTransaction`.

-
-Some snags and todos
-
-* [ ] Clef should take a startup param "--no-change", for UIs that do not contain the capability to perform changes to things, only approve/deny. Such a UI should be able to start the signer in a more secure mode by telling it that it only wants approve/deny capabilities.
-* [x] It would be nice if Clef could collect new 4byte-id:s/method selectors, and have a secondary database for those (`4byte_custom.json`). Users could then (optionally) submit their collections for inclusion upstream.
-* [ ] It should be possible to configure Clef to check if an account is indeed known to it, before passing on to the UI. The reason it currently does not, is that it would make it possible to enumerate accounts if it immediately returned "unknown account" (side channel attack).
-* [x] It should be possible to configure Clef to auto-allow listing (certain) accounts, instead of asking every time.
-* [x] Done Upon startup, Clef should spit out some info to the caller (particularly important when executed in `stdio-ui`-mode), invoking methods with the following info:
-  * [x] Version info about the signer
-  * [x] Address of API (HTTP/IPC)
-  * [ ] List of known accounts
-* [ ] Have a default timeout on signing operations, so that if the user has not answered within e.g. 60 seconds, the request is rejected.
-* [ ] `account_signRawTransaction`
-* [ ] `account_bulkSignTransactions([] transactions)` should
-   * only exist if enabled via config/flag
-   * only allow non-data-sending transactions
-   * all txs must use the same `from`-account
-   * let the user confirm, showing
-      * the total amount
-      * the number of unique recipients
-
-* Geth todos
-    - The signer should pass the `Origin` header as call-info to the UI. As of right now, the way that info about the request is put together is a bit of a hack into the HTTP server. This could probably be greatly improved.
-    - Relay: Geth should be started in `geth --signer localhost:8550`.
-    - Currently, the Geth APIs use `common.Address` in the arguments to transaction submission (e.g `to` field). This type is 20 `bytes`, and is incapable of carrying checksum information. The signer uses `common.MixedcaseAddress`, which retains the original input.
-    - The Geth API should switch to use the same type, and relay `to`-account verbatim to the external API.
-* [x] Storage
-    * [x] An encrypted key-value storage should be implemented.
-    * See [rules.md](rules.md) for more info about this.
-* Another potential thing to introduce is pairing.
-  * To prevent spurious requests which users just accept, implement a way to "pair" the caller with the signer (external API).
-  * Thus Geth/cpp would cryptographically handshake and afterwards the caller would be allowed to make signing requests.
-  * This feature would make the addition of rules less dangerous.
-
-* Wallets / accounts. Add API methods for wallets.
-
-## Communication
-
-### External API
-
-Clef listens to HTTP requests on `http.addr`:`http.port` (or to IPC on `ipcpath`), with the same JSON-RPC standard as Geth. The messages are expected to be [JSON-RPC 2.0 standard](https://www.jsonrpc.org/specification).
-
-Some of these calls can require user interaction. Clients must be aware that responses may be delayed significantly or may never be received if a user decides to ignore the confirmation request.
-
-The External API is **untrusted**: it does not accept credentials, nor does it expect that requests have any authority.
-
-### Internal UI API
-
-Clef has one native console-based UI, for operation without any standalone tools. However, there is also an API to communicate with an external UI. To enable that UI, the signer needs to be executed with the `--stdio-ui` option, which allocates `stdin` / `stdout` for the UI API.
-
-An example (insecure) proof-of-concept has been implemented in `pythonsigner.py`.
-
-The model is as follows:
-
-* The user starts the UI app (`pythonsigner.py`).
-* The UI app starts `clef` with `--stdio-ui`, and listens to the
-process output for confirmation-requests.
-* `clef` opens the external HTTP API.
-* When the `signer` receives requests, it sends a JSON-RPC request via `stdout`.
-* The UI app prompts the user accordingly, and responds to `clef`.
-* `clef` signs (or not), and responds to the original request.
-
-## External API
-
-See the [external API changelog](extapi_changelog.md) for information about changes to this API.
-
-### Encoding
-- number: positive integers that are hex encoded
-- data: hex encoded data
-- string: ASCII string
-
-All hex encoded values must be prefixed with `0x`.
-
-### account_new
-
-#### Create new password protected account
-
-The signer will generate a new private key, encrypt it according to [web3 keystore spec](https://ethereum.org/en/developers/docs/data-structures-and-encoding/web3-secret-storage/) and store it in the keystore directory.  
-The client is responsible for creating a backup of the keystore. If the keystore is lost there is no method of retrieving lost accounts.

-### account_signTransaction
-
-#### Sign transactions
-   Signs a transaction and responds with the signed transaction in RLP-encoded and JSON forms.
-
-#### Arguments
-  1. transaction object:
-     - `from` [address]: account to send the transaction from
-     - `to` [address]: receiver account. If omitted or `0x`, will cause contract creation.
-     - `gas` [number]: maximum amount of gas to burn
-     - `gasPrice` [number]: gas price
-     - `value` [number:optional]: amount of Wei to send with the transaction
-     - `data` [data:optional]:  input data
-     - `nonce` [number]: account nonce
-  2. method signature [string:optional]
-       - The method signature, if present, is to aid decoding the calldata. Should consist of `methodname(paramtype,...)`, e.g. `transfer(uint256,address)`. The signer may use this data to parse the supplied calldata, and show the user. The data, however, is considered totally untrusted, and reliability is not expected.

-## UI API
-
-These methods needs to be implemented by a UI listener.
-
-By starting the signer with the switch `--stdio-ui-test`, the signer will invoke all known methods, and expect the UI to respond with
-denials. This can be used during development to ensure that the API is (at least somewhat) correctly implemented.
-See `pythonsigner`, which can be invoked via `python3 pythonsigner.py test` to perform the 'denial-handshake-test'.
-
-All methods in this API use object-based parameters, so that there can be no mixup of parameters: each piece of data is accessed by key.
-
-See the [ui API changelog](intapi_changelog.md) for information about changes to this API.
-
-OBS! A slight deviation from `json` standard is in place: every request and response should be confined to a single line.
-Whereas the `json` specification allows for linebreaks, linebreaks __should not__ be used in this communication channel, to make
-things simpler for both parties.
-
-### ApproveTx / `ui_approveTx`
-
-Invoked when there's a transaction for approval.

-The UI should show the info (a single message) to the user. Does not expect response.
-
-#### Sample call
-
-```json

-  "jsonrpc": "2.0",
-  "id": 9,

-
-The UI should show the error (a single message) to the user. Does not expect response.
-
-```json

-  "jsonrpc": "2.0",
-  "id": 2,
-  "method": "ui_showError",
-  "params": [
-    "Something bad happened!"
-  ]
-}
-
-```
-
-### OnApprovedTx / `ui_onApprovedTx`
-
-`OnApprovedTx` is called when a transaction has been approved and signed. The call contains the return value that will be sent to the external caller.  The return value from this method is ignored - the reason for having this callback is to allow the ruleset to keep track of approved transactions.
-
-When implementing rate-limited rules, this callback should be used.
-
-TLDR; Use this method to keep track of signed transactions, instead of using the data in `ApproveTx`.
-
-Example call:
-```json
-
-{
-  "jsonrpc": "2.0",
-  "id": 1,
-  "method": "ui_onApprovedTx",
-  "params": [
-    {
-      "raw": "0xf88380018203339407a565b7ed7d7a678680a4c162885bedbb695fe080a44401a6e4000000000000000000000000000000000000000000000000000000000000001226a0223a7c9bcf5531c99be5ea7082183816eb20cfe0bbc322e97cc5c7f71ab8b20ea02aadee6b34b45bb15bc42d9c09de4a6754e7000908da72d48cc7704971491663",

-      }
-    }
-  ]
-}
-```
-
-### OnSignerStartup / `ui_onSignerStartup`
-
-This method provides the UI with information about what API version the signer uses (both internal and external) as well as build-info and external API,
-in k/v-form.
-
-Example call:
-```json
-
-{
-  "jsonrpc": "2.0",
-  "id": 1,
-  "method": "ui_onSignerStartup",
-  "params": [
-    {
-      "info": {

-        "extapi_version": "2.0.0",
-        "intapi_version": "1.2.0"
-      }
-    }
-  ]
-}
-
-```
-
-### OnInputRequired / `ui_onInputRequired`
-
-Invoked when Clef requires user input (e.g. a password).
-
-Example call:
-```json
-
-{
-  "jsonrpc": "2.0",
-  "id": 1,
-  "method": "ui_onInputRequired",
-  "params": [
-    {
-      "title": "Account password",
-      "prompt": "Please enter the password for account 0x694267f14675d7e1b9494fd8d72fefe1755710fa",
-      "isPassword": true
-    }
-  ]
-}
-```
-
-
-### Rules for UI apis
-
-A UI should conform to the following rules.
-
-* A UI MUST NOT load any external resources that were not embedded/part of the UI package.
-  * For example, not load icons, stylesheets from the internet
-  * Not load files from the filesystem, unless they reside in the same local directory (e.g. config files)
-* A Graphical UI MUST show the blocky-identicon for ethereum addresses.
-* A UI MUST warn display appropriate warning if the destination-account is formatted with invalid checksum.
-* A UI MUST NOT open any ports or services
-  * The signer opens the public port
-* A UI SHOULD verify the permissions on the signer binary, and refuse to execute or warn if permissions allow non-user write.
-* A UI SHOULD inform the user about the `SHA256` or `MD5` hash of the binary being executed
-* A UI SHOULD NOT maintain a secondary storage of data, e.g. list of accounts
-  * The signer provides accounts
-* A UI SHOULD, to the best extent possible, use static linking / bundling, so that required libraries are bundled
-along with the UI.
-
-
-### UI Implementations
-
-There are a couple of implementation for a UI. We'll try to keep this list up to date.
-
-| Name | Repo | UI type| No external resources| Blocky support| Verifies permissions | Hash information | No secondary storage | Statically linked| Can modify parameters|

Clef has done most of the work in canonicalizing and making sense of the data, and it's up to the UI to present the user with the contents of the `message`
-
-Example:
-```json
-{
-  "content_type": "text/plain",
-  "address": "0xDEADbEeF000000000000000000000000DeaDbeEf",
-  "raw_data": "GUV0aGVyZXVtIFNpZ25lZCBNZXNzYWdlOgoxMWhlbGxvIHdvcmxk",
-  "messages": [
-    {
-      "name": "message",
-      "value": "\u0019Ethereum Signed Message:\n11hello world",
-      "type": "text/plain"
-    }
-  ],
-  "hash": "0xd9eba16ed0ecae432b71fe008c98cc872bb4cc214d3220a36f365326cf807d68",
-  "meta": {
-    "remote": "localhost:9999",
-    "local": "localhost:8545",
-    "scheme": "http",
-    "User-Agent": "Firefox 3.2",
-    "Origin": "www.malicious.ru"
-  }
-}
-```
-### SignDataResponse - approve
-
-Response to SignDataRequest
-
-Example:
-```json
-{
-  "approved": true
-}
-```
-### SignDataResponse - deny
-
-Response to SignDataRequest
-
-Example:
-```json
-{
-  "approved": false
-}
-```
-### SignTxRequest
-
-SignTxRequest contains information about a pending request to sign a transaction. Aside from the transaction itself, there is also a `call_info`-struct. That struct contains messages of various types, that the user should be informed of.
-
-As in any request, it's important to consider that the `meta` info also contains untrusted data.
-
-The `transaction` (on input into clef) can have either `data` or `input` -- if both are set, they must be identical, otherwise an error is generated. However, Clef will always use `data` when passing this struct on (if Clef does otherwise, please file a ticket)
-
-Example:
-```json
-{
-  "transaction": {
-    "from": "0xDEADbEeF000000000000000000000000DeaDbeEf",
-    "to": null,
-    "gas": "0x3e8",
-    "gasPrice": "0x5",
-    "value": "0x6",
-    "nonce": "0x1",
-    "data": "0x01020304"
-  },
-  "call_info": [
-    {
-      "type": "Warning",
-      "message": "Something looks odd, show this message as a warning"
-    },
-    {
-      "type": "Info",
-      "message": "User should see this as well"
-    }
-  ],
-  "meta": {
-    "remote": "localhost:9999",
-    "local": "localhost:8545",
-    "scheme": "http",
-    "User-Agent": "Firefox 3.2",
-    "Origin": "www.malicious.ru"
-  }
-}
-```
-### SignTxResponse - approve
-
-Response to request to sign a transaction. This response needs to contain the `transaction`, because the UI is free to make modifications to the transaction.
-
-Example:
-```json
-{
-  "transaction": {
-    "from": "0xDEADbEeF000000000000000000000000DeaDbeEf",
-    "to": null,
-    "gas": "0x3e8",
-    "gasPrice": "0x5",
-    "value": "0x6",
-    "nonce": "0x4",
-    "data": "0x04030201"
-  },
-  "approved": true
-}
-```
-### SignTxResponse - deny
-
-Response to SignTxRequest. When denying a request, there's no need to provide the transaction in return
-
-Example:
-```json
-{
-  "transaction": {
-    "from": "0x",
-    "to": null,
-    "gas": "0x0",
-    "gasPrice": "0x0",
-    "value": "0x0",
-    "nonce": "0x0",
-    "data": null
-  },
-  "approved": false
-}
-```
-### OnApproved - SignTransactionResult
-
-SignTransactionResult is used in the call `clef` -> `OnApprovedTx(result)`
-
-This occurs _after_ successful completion of the entire signing procedure, but right before the signed transaction is passed to the external caller. This method (and data) can be used by the UI to signal to the user that the transaction was signed, but it is primarily useful for ruleset implementations.
-
-A ruleset that implements a rate limitation needs to know what transactions are sent out to the external interface. By hooking into this methods, the ruleset can maintain track of that count.
-
-**OBS:** Note that if an attacker can restore your `clef` data to a previous point in time (e.g through a backup), the attacker can reset such windows, even if he/she is unable to decrypt the content.
-
-The `OnApproved` method cannot be responded to, it's purely informative
-
-Example:
-```json
-{
-  "raw": "0xf85d640101948a8eafb1cf62bfbeb1741769dae1a9dd47996192018026a0716bd90515acb1e68e5ac5867aa11a1e65399c3349d479f5fb698554ebc6f293a04e8a4ebfff434e971e0ef12c5bf3a881b06fd04fc3f8b8a7291fb67a26a1d4ed",
-  "tx": {
-    "nonce": "0x64",
-    "gasPrice": "0x1",
-    "gas": "0x1",
-    "to": "0x8a8eafb1cf62bfbeb1741769dae1a9dd47996192",
-    "value": "0x1",
-    "input": "0x",
-    "v": "0x26",
-    "r": "0x716bd90515acb1e68e5ac5867aa11a1e65399c3349d479f5fb698554ebc6f293",

-  }
-}
-```
-### UserInputRequest
-
-Sent when clef needs the user to provide data. If 'password' is true, the input field should be treated accordingly (echo-free)
-
-Example:
-```json
-{
-  "prompt": "The question to ask the user",
-  "title": "The title here",
-  "isPassword": true
-}
-```
-### UserInputResponse
-
-Response to UserInputRequest
-
-Example:
-```json
-{
-  "text": "The textual response from user"
-}
-```
-### ListRequest
-
-Sent when a request has been made to list addresses. The UI is provided with the full `account`s, including local directory names. Note: this information is not passed back to the external caller, who only sees the `address`es.
-
-Example:
-```json
-{
-  "accounts": [
-    {
-      "address": "0xdeadbeef000000000000000000000000deadbeef",
-      "url": "keystore:///path/to/keyfile/a"
-    },
-    {
-      "address": "0x1111111122222222222233333333334444444444",
-      "url": "keystore:///path/to/keyfile/b"
-    }
-  ],
-  "meta": {
-    "remote": "localhost:9999",
-    "local": "localhost:8545",
-    "scheme": "http",
-    "User-Agent": "Firefox 3.2",
-    "Origin": "www.malicious.ru"
-  }
-}
-```
-### ListResponse
-
-Response to list request. The response contains a list of all addresses to show to the caller. Note: the UI is free to respond with any address the caller, regardless of whether it exists or not
-
-Example:
-```json
-{
-  "accounts": [
-    {
-      "address": "0x0000000000000000000000000000000000000000",
-      "url": ".. ignored .."
-    },
-    {
-      "address": "0xffffffffffffffffffffffffffffffffffffffff",

-# Setting up Clef
-
-This document describes how Clef can be used in a more secure manner than executing it from your everyday laptop, 
-in order to ensure that the keys remain safe in the event that your computer should get compromised. 
-
-## Qubes OS
-
-
-### Background 
-
-The Qubes operating system is based around virtual machines (qubes), where a set of virtual machines are configured, typically for 
-different purposes such as:
-
-- personal
-   - Your personal email, browsing etc
-- work
-  - Work email etc
-- vault
-  - a VM without network access, where gpg-keys and/or keepass credentials are stored. 
-
-A couple of dedicated virtual machines handle externalities:
-
-- sys-net provides networking to all other (network-enabled) machines
-- sys-firewall handles firewall rules
-- sys-usb handles USB devices, and can map usb-devices to certain qubes.
-
-The goal of this document is to describe how we can set up clef to provide secure transaction
-signing from a `vault` vm, to another networked qube which runs Dapps.
-
-### Setup
-
-There are two ways that this can be achieved: integrated via Qubes or integrated via networking. 
-
-
-#### 1. Qubes Integrated
-
-Qubes provides a facility for inter-qubes communication via `qrexec`. A qube can request to make a cross-qube RPC request 
-to another qube. The OS then asks the user if the call is permitted. 
-
-![Example](qubes/qrexec-example.png)
-
-A policy-file can be created to allow such interaction. On the `target` domain, a service is invoked which can read the
-`stdin` from the `client` qube. 
-
-This is how [Split GPG](https://www.qubes-os.org/doc/split-gpg/) is implemented. We can set up Clef the same way:
-
-##### Server
-
-![Clef via qrexec](qubes/clef_qubes_qrexec.png)
-
-On the `target` qubes, we need to define the RPC service.
-
-[qubes.Clefsign](qubes/qubes.Clefsign):
-
-```bash
-#!/bin/bash
-
-SIGNER_BIN="/home/user/tools/clef/clef"
-SIGNER_CMD="/home/user/tools/gtksigner/gtkui.py -s $SIGNER_BIN"
-
-# Start clef if not already started
-if [ ! -S /home/user/.clef/clef.ipc ]; then
-	$SIGNER_CMD &
-	sleep 1
-fi
-
-# Should be started by now
-if [ -S /home/user/.clef/clef.ipc ]; then
-    # Post incoming request to HTTP channel
-	curl -H "Content-Type: application/json" -X POST -d @- http://localhost:8550 2>/dev/null
-fi
-
-```
-This RPC service is not complete (see notes about HTTP headers below), but works as a proof-of-concept. 
-It will forward the data received on `stdin` (forwarded by the OS) to Clef's HTTP channel.  
-
-It would have been possible to send data directly to the `/home/user/.clef/.clef.ipc` 
-socket via e.g `nc -U /home/user/.clef/clef.ipc`, but the reason for sending the request 
-data over `HTTP` instead of `IPC` is that we want the ability to forward `HTTP` headers.
-
-To enable the service:
-
-``` bash
-sudo cp qubes.Clefsign /etc/qubes-rpc/
-sudo chmod +x /etc/qubes-rpc/ qubes.Clefsign
-```
-
-This setup uses [gtksigner](https://github.com/holiman/gtksigner), which is a very minimal GTK-based UI that works well 
-with minimal requirements. 
-
-##### Client
-
-
-On the `client` qube, we need to create a listener which will receive the request from the Dapp, and proxy it. 
-
-
-[qubes-client.py](qubes/qubes-client.py):
-
-```python
-
-"""
-This implements a dispatcher which listens to localhost:8550, and proxies
-requests via qrexec to the service qubes.EthSign on a target domain
-"""
-
-import http.server
-import socketserver,subprocess
-
-PORT=8550
-TARGET_DOMAIN= 'debian-work'
-
-class Dispatcher(http.server.BaseHTTPRequestHandler):
-    def do_POST(self):
-        post_data = self.rfile.read(int(self.headers['Content-Length']))
-        p = subprocess.Popen(['/usr/bin/qrexec-client-vm',TARGET_DOMAIN,'qubes.Clefsign'],stdin=subprocess.PIPE, stdout=subprocess.PIPE)
-        output = p.communicate(post_data)[0]
-        self.wfile.write(output)
-
-
-with socketserver.TCPServer(("",PORT), Dispatcher) as httpd:
-    print("Serving at port", PORT)
-    httpd.serve_forever()
-
-
-```
-
-#### Testing
-
-To test the flow, if we have set up `debian-work` as the `target`, we can do
- 
-```bash
-$ cat newaccnt.json 
-{ "id": 0, "jsonrpc": "2.0","method": "account_new","params": []}
-
-$ cat newaccnt.json| qrexec-client-vm debian-work qubes.Clefsign
-```
-
-A dialog should pop up first to allow the IPC call:
-
-![one](qubes/qubes_newaccount-1.png)
-
-Followed by a GTK-dialog to approve the operation:
-
-![two](qubes/qubes_newaccount-2.png)
-
-To test the full flow, we use the client wrapper. Start it on the `client` qube:
-```
-[user@work qubes]$ python3 qubes-client.py 
-```
-
-Make the request over http (`client` qube):
-```
-[user@work clef]$ cat newaccnt.json | curl -X POST -d @- http://localhost:8550
-```
-And it should show the same popups again. 
-
-##### Pros and cons
-
-The benefits of this setup are:
-
-- This is the qubes-os intended model for inter-qube communication,
-- and thus benefits from qubes-os dialogs and policies for user approval
-
-However, it comes with a couple of drawbacks:
-
-- The `qubes-gpg-client` must forward the http request via RPC to the `target` qube. When doing so, the proxy
-  will either drop important headers, or replace them. 
-  - The `Host` header is most likely `localhost` 
-  - The `Origin` header must be forwarded
-  - Information about the remote ip must be added as a `X-Forwarded-For`. However, Clef cannot always trust an `XFF` header, 
-  since malicious clients may lie about `XFF` in order to fool the http server into believing it comes from another address.
-- Even with a policy in place to allow RPC calls between `caller` and `target`, there will be several popups:
-  - One qubes-specific where the user specifies the `target` vm
-  - One clef-specific to approve the transaction
-  
-
-#### 2. Network integrated
-
-The second way to set up Clef on a qubes system is to allow networking, and have Clef listen to a port which is accessible
-from other qubes. 
-

-## USBArmory
-
-The [USB armory](https://inversepath.com/usbarmory) is an open source hardware design with an 800 MHz ARM processor. It is a pocket-size
-computer. When inserted into a laptop, it identifies itself as a USB network interface, basically adding another network
-to your computer. Over this new network interface, you can SSH into the device. 
-
-Running Clef off a USB armory means that you can use the armory as a very versatile offline computer, which only
-ever connects to a local network between your computer and the device itself.
-
-Needless to say, while this model should be fairly secure against remote attacks, an attacker with physical access
-to the USB Armory would trivially be able to extract the contents of the device filesystem.

-Not all fields are required, though. This method is really just a UX helper, which massages the 
-input to conform to the `EIP-712` [specification](https://docs.safe.global/core-api/transaction-service-reference/gnosis) 
-for the Gnosis Safe, and making the output be directly importable to by a relay service. 
-
-
-### 6.0.0
-
-* `New` was changed to deliver only an address, not the full `Account` data
-* `Export` was moved from External API to the UI Server API
-
-#### 5.0.0
-
-* The external `account_EcRecover`-method was reimplemented.
-* The external method `account_sign(address, data)` was replaced with `account_signData(contentType, address, data)`.
-The addition of `contentType` makes it possible to use the method for different types of objects, such as:
-  * signing data with an intended validator (not yet implemented)
-  * signing clique headers,
-  * signing plain personal messages,
-* The external method `account_signTypedData` implements [EIP-712](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md) and makes it possible to sign typed data.
-
-#### 4.0.0
-
-* The external `account_Ecrecover`-method was removed.
-* The external `account_Import`-method was removed.
-
-#### 3.0.0
-
-* The external `account_List`-method was changed to not expose `url`, which contained info about the local filesystem. It now returns only a list of addresses.
-
-#### 2.0.0
-
-* Commit `73abaf04b1372fa4c43201fb1b8019fe6b0a6f8d`, move `from` into `transaction` object in `signTransaction`. This
-makes the `accounts_signTransaction` identical to the old `eth_signTransaction`.
-
-
-#### 1.0.0
-
-Initial release.

-- The `message` field was renamed to `messages` in all data signing request methods to better reflect that it's a list, not a value.
-- The `storage.Put` and `storage.Get` methods in the rule execution engine were lower-cased to `storage.put` and `storage.get` to be consistent with JavaScript call conventions.
-
-### 6.0.0
-
-Removed `password` from responses to operations which require them. This is for two reasons,
-
-- Consistency between how rulesets operate and how manual processing works. A rule can `Approve` but require the actual password to be stored in the clef storage.
-With this change, the same stored password can be used even if rulesets are not enabled, but storage is.
-- It also removes the usability-shortcut that a UI might otherwise want to implement; remembering passwords. Since we now will not require the
-password on every `Approve`, there's no need for the UI to cache it locally.
-  - In a future update, we'll likely add `clef_storePassword` to the internal API, so the user can store it via his UI (currently only CLI works).
-
-Affected datatypes:
-- `SignTxResponse`
-- `SignDataResponse`
-- `NewAccountResponse`
-
-If `clef` requires a password, the `OnInputRequired` will be used to collect it.
-
-
-### 5.0.0
-
-Changed the namespace format to adhere to the legacy ethereum format: `name_methodName`. Changes:
-
-* `ApproveTx` -> `ui_approveTx`
-* `ApproveSignData` -> `ui_approveSignData`
-* `ApproveExport` -> `removed`
-* `ApproveImport`  -> `removed`
-* `ApproveListing`  -> `ui_approveListing`
-* `ApproveNewAccount`  -> `ui_approveNewAccount`
-* `ShowError` -> `ui_showError`
-* `ShowInfo` -> `ui_showInfo`
-* `OnApprovedTx` -> `ui_onApprovedTx`
-* `OnSignerStartup` -> `ui_onSignerStartup`
-* `OnInputRequired` -> `ui_onInputRequired`
-
-
-### 4.0.0
-
-* Bidirectional communication implemented, so the UI can query `clef` via the stdin/stdout RPC channel. Methods implemented are:
-  - `clef_listWallets`
-  - `clef_listAccounts`
-  - `clef_listWallets`
-  - `clef_deriveAccount`
-  - `clef_importRawKey`
-  - `clef_openWallet`
-  - `clef_chainId`
-  - `clef_setChainId`
-  - `clef_export`
-  - `clef_import`
-
-* The type `Account` was modified (the json-field `type` was removed), to consist of
-
-```go
-type Account struct {
-	Address common.Address `json:"address"` // Ethereum account address derived from the key
-	URL     URL            `json:"url"`     // Optional resource locator within a backend
-}
-```
-
-
-### 3.2.0
-
-* Make `ShowError`, `OnApprovedTx`, `OnSignerStartup` be json-rpc [notifications](https://www.jsonrpc.org/specification#notification):
-
-> A Notification is a Request object without an "id" member. A Request object that is a Notification signifies the Client's lack of interest in the corresponding Response object, and as such no Response object needs to be returned to the client. The Server MUST NOT reply to a Notification, including those that are within a batch request.
->
->  Notifications are not confirmable by definition, since they do not have a Response object to be returned. As such, the Client would not be aware of any errors (like e.g. "Invalid params","Internal error"
-### 3.1.0
-
-* Add `ContentType` `string` to `SignDataRequest` to accommodate the latest [EIP-191](https://eips.ethereum.org/EIPS/eip-191) and [EIP-712](https://eips.ethereum.org/EIPS/eip-712) implementations.
-
-### 3.0.0
-
-* Make use of `OnInputRequired(info UserInputRequest)` for obtaining master password during startup
-
-### 2.1.0
-
-* Add `OnInputRequired(info UserInputRequest)` to internal API. This method is used when Clef needs user input, e.g. passwords.
-
-The following structures are used:
-
-```go
-UserInputRequest struct {
-	Prompt     string `json:"prompt"`
-	Title      string `json:"title"`
-	IsPassword bool   `json:"isPassword"`
-}
-UserInputResponse struct {
-	Text string `json:"text"`
-}
-```
-
-### 2.0.0
-
-* Modify how `call_info` on a transaction is conveyed. New format:
-
-```
-{
-  "jsonrpc": "2.0",
-  "id": 2,
-  "method": "ApproveTx",
-  "params": [
-    {

-        "input": null
-      },
-      "call_info": [
-        {
-          "type": "WARNING",
-          "message": "Invalid checksum on to-address"
-        },
-        {
-          "type": "WARNING",
-          "message": "Tx contains data, but provided ABI signature could not be matched: Did not match: test (0 matches)"

-        "scheme": "HTTP/1.1"
-      }
-    }
-  ]
-}
-```
-
-#### 1.2.0
-
-* Add `OnStartup` method, to provide the UI with information about what API version
-the signer uses (both internal and external) as well as build-info and external api.
-
-Example call:
-```json
-{
-  "jsonrpc": "2.0",
-  "id": 1,
-  "method": "OnSignerStartup",
-  "params": [
-    {
-      "info": {
-        "extapi_http": "http://localhost:8550",
-        "extapi_ipc": null,
-        "extapi_version": "2.0.0",
-        "intapi_version": "1.2.0"
-      }
-    }
-  ]
-}
-```
-
-#### 1.1.0
-
-* Add `OnApproved` method
-
-#### 1.0.0
-
-Initial release.

-# Rules
-
-The `signer` binary contains a ruleset engine, implemented with [OttoVM](https://github.com/robertkrimen/otto)
-
-It enables use cases like the following:
-
-* I want to auto-approve transactions with contract `CasinoDapp`, with up to `0.05 ether` in value to maximum `1 ether` per 24h period
-* I want to auto-approve transaction to contract `EthAlarmClock` with `data`=`0xdeadbeef`, if `value=0`, `gas < 44k` and `gasPrice < 40Gwei`
-
-The two main features that are required for this to work well are:
-
-1. Rule Implementation: how to create, manage, and interpret rules in a flexible but secure manner
-2. Credential management and credentials; how to provide auto-unlock without exposing keys unnecessarily.
-
-The section below deals with both of them
-
-## Rule Implementation
-
-A ruleset file is implemented as a `js` file. Under the hood, the ruleset engine is a `SignerUI`, implementing the same methods as the `json-rpc` methods
-defined in the UI protocol. Example:
-
-```js
-function asBig(str) {
-	if (str.slice(0, 2) == "0x") {
-		return new BigNumber(str.slice(2), 16)
-	}
-	return new BigNumber(str)
-}
-
-// Approve transactions to a certain contract if the value is below a certain limit
-function ApproveTx(req) {
-	var limit = new BigNumber("0xb1a2bc2ec50000")
-	var value = asBig(req.transaction.value);

-}
-
-// Approve listings if request made from IPC
-function ApproveListing(req){
-    if (req.metadata.scheme == "ipc"){ return "Approve"}
-}
-```
-
-Whenever the external API is called (and the ruleset is enabled), the `signer` calls the UI, which is an instance of a ruleset-engine. The ruleset-engine
-invokes the corresponding method. In doing so, there are three possible outcomes:
-
-1. JS returns "Approve"
-  * Auto-approve request
-2. JS returns "Reject"
-  * Auto-reject request
-3. Error occurs, or something else is returned
-  * Pass on to `next` ui: the regular UI channel.
-
-A more advanced example can be found below, "Example 1: ruleset for a rate-limited window", using `storage` to `Put` and `Get` `string`s by key.
-
-* At the time of writing, storage only exists as an ephemeral unencrypted implementation, to be used during testing.
-
-### Things to note
-
-The Otto vm has a few [caveats](https://github.com/robertkrimen/otto):
-
-* "use strict" will parse, but does nothing.
-* The regular expression engine (re2/regexp) is not fully compatible with the ECMA5 specification.
-* Otto targets ES5. ES6 features (eg: Typed Arrays) are not supported.
-
-Additionally, a few more have been added
-
-* The rule execution cannot load external javascript files.
-* The only preloaded library is [`bignumber.js`](https://github.com/MikeMcl/bignumber.js) version `2.0.3`. This one is fairly old, and is not aligned with the documentation at the GitHub repository.
-* Each invocation is made in a fresh virtual machine. This means that you cannot store data in global variables between invocations. This is a deliberate choice -- if you want to store data, use the disk-backed `storage`, since rules should not rely on ephemeral data.
-* Javascript API parameters are _always_ an object. This is also a design choice, to ensure that parameters are accessed by _key_ and not by order. This is to prevent mistakes due to missing parameters or parameter changes.
-* The JS engine has access to `storage` and `console`.
-
-#### Security considerations
-
-##### Security of ruleset
-
-Some security precautions can be made, such as:
-
-* Never load `ruleset.js` unless the file is `readonly` (`r-??-??-?`). If the user wishes to modify the ruleset, he must make it writeable and then set back to readonly.
-  * This is to prevent attacks where files are dropped on the users disk.
-* Since we're going to have to have some form of secure storage (not defined in this section), we could also store the `sha3` of the `ruleset.js` file in there.
-  * If the user wishes to modify the ruleset, he'd then have to perform e.g. `signer --attest /path/to/ruleset --credential <creds>`
-
-##### Security of implementation
-
-The drawback of this very flexible solution is that the `signer` needs to contain a javascript engine. This is pretty simple to implement since it's already
-implemented for `geth`. There are no known security vulnerabilities in it, nor have we had any security problems with it so far.
-
-The javascript engine would be an added attack surface; but if the validation of `rulesets` is made good (with hash-based attestation), the actual javascript cannot be considered
-an attack surface -- if an attacker can control the ruleset, a much simpler attack would be to implement an "always-approve" rule instead of exploiting the js vm. The only benefit
-to be gained from attacking the actual `signer` process from the `js` side would be if it could somehow extract cryptographic keys from memory.
-
-##### Security in usability
-
-Javascript is flexible, but also easy to get wrong, especially when users assume that `js` can handle large integers natively. Typical errors
-include trying to multiply `gasCost` with `gas` without using `bigint`:s.
-
-It's unclear whether any other DSL could be more secure; since there's always the possibility of erroneously implementing a rule.
-
-
-## Credential management
-
-The ability to auto-approve transactions means that the signer needs to have the necessary credentials to decrypt keyfiles. These passwords are hereafter called `ksp` (keystore pass).
-
-### Example implementation
-
-Upon startup of the signer, the signer is given a switch: `--seed <path/to/masterseed>`
-The `seed` contains a blob of bytes, which is the master seed for the `signer`.
-
-The `signer` uses the `seed` to:
-
-* Generate the `path` where the settings are stored.
-  * `./settings/1df094eb-c2b1-4689-90dd-790046d38025/vault.dat`
-  * `./settings/1df094eb-c2b1-4689-90dd-790046d38025/rules.js`
-* Generate the encryption password for `vault.dat`.
-
-The `vault.dat` would be an encrypted container storing the following information:
-
-* `ksp` entries
-* `sha256` hash of `rules.js`
-* Information about pair:ed callers (not yet specified)
-
-### Security considerations
-
-This would leave it up to the user to ensure that the `path/to/masterseed` is handled securely. It's difficult to get around this, although one could
-imagine leveraging OS-level keychains where supported. The setup is however, in general, similar to how ssh-keys are stored in `.ssh/`.
-
-
-# Implementation status
-
-This is now implemented (with ephemeral non-encrypted storage for now, so not yet enabled).
-
-## Example 1: ruleset for a rate-limited window
-
-
-```js
-function big(str) {
-	if (str.slice(0, 2) == "0x") {
-		return new BigNumber(str.slice(2), 16)
-	}
-	return new BigNumber(str)
-}
-
-// Time window: 1 week
-var window = 1000* 3600*24*7;
-
-// Limit: 1 ether
-var limit = new BigNumber("1e18");
-
-function isLimitOk(transaction) {
-	var value = big(transaction.value)
-	// Start of our window function
-	var windowstart = new Date().getTime() - window;
-
-	var txs = [];
-	var stored = storage.get('txs');
-
-	if (stored != "") {
-		txs = JSON.parse(stored)
-	}
-	// First, remove all that has passed out of the time window
-	var newtxs = txs.filter(function(tx){return tx.tstamp > windowstart});
-	console.log(txs, newtxs.length);
-
-	// Secondly, aggregate the current sum
-	sum = new BigNumber(0)
-
-	sum = newtxs.reduce(function(agg, tx){ return big(tx.value).plus(agg)}, sum);
-	console.log("ApproveTx > Sum so far", sum);
-	console.log("ApproveTx > Requested", value.toNumber());
-
-	// Would we exceed the weekly limit ?
-	return sum.plus(value).lt(limit)
-
-}
-function ApproveTx(r) {
-	if (isLimitOk(r.transaction)) {
-		return "Approve"
-	}
-	return "Nope"
-}
-
-/**
-* OnApprovedTx(str) is called when a transaction has been approved and signed. The parameter
-	* 'response_str' contains the return value that will be sent to the external caller.
-* The return value from this method is ignore - the reason for having this callback is to allow the
-* ruleset to keep track of approved transactions.
-*
-* When implementing rate-limited rules, this callback should be used.
-* If a rule responds with neither 'Approve' nor 'Reject' - the tx goes to manual processing. If the user
-* then accepts the transaction, this method will be called.
-*
-* TLDR; Use this method to keep track of signed transactions, instead of using the data in ApproveTx.
-*/
-function OnApprovedTx(resp) {
-	var value = big(resp.tx.value)
-	var txs = []
-	// Load stored transactions
-	var stored = storage.get('txs');
-	if (stored != "") {
-		txs = JSON.parse(stored)
-	}
-	// Add this to the storage
-	txs.push({tstamp: new Date().getTime(), value: value});
-	storage.put("txs", JSON.stringify(txs));
-}
-```
-
-## Example 2: allow destination
-
-```js
-function ApproveTx(r) {
-	if (r.transaction.from.toLowerCase() == "0x0000000000000000000000000000000000001337") {
-		return "Approve"
-	}
-	if (r.transaction.from.toLowerCase() == "0x000000000000000000000000000000000000dead") {
-		return "Reject"
-	}
-	// Otherwise goes to manual processing
-}
-```
-
-## Example 3: Allow listing
-
-```js
-function ApproveListing() {
-	return "Approve"

-## Initializing Clef
-
-First things first, Clef needs to store some data itself. Since that data might be sensitive (passwords, signing rules, accounts), Clef's entire storage is encrypted. To support encrypting data, the first step is to initialize Clef with a random master seed, itself too encrypted with your chosen password:
-
-```text
-$ clef init
-
-WARNING!
-
-Clef is an account management tool. It may, like any software, contain bugs.
-
-Please take care to
-- backup your keystore files,
-- verify that the keystore(s) can be opened with your password.
-
-Clef is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY;
-without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR
-PURPOSE. See the GNU General Public License for more details.
-
-Enter 'ok' to proceed:
-> ok
-
-The master seed of clef will be locked with a password.
-Please specify a password. Do not forget this password!
-Password:
-Repeat password:
-
-A master seed has been generated into /home/martin/.clef/masterseed.json
-
-This is required to be able to store credentials, such as:
-* Passwords for keystores (used by rule engine)
-* Storage for JavaScript auto-signing rules
-* Hash of JavaScript rule-file
-
-You should treat 'masterseed.json' with utmost secrecy and make a backup of it!
-* The password is necessary but not enough, you need to back up the master seed too!
-* The master seed does not contain your accounts, those need to be backed up separately!
-```
-
-*For readability purposes, we'll remove the WARNING printout, user confirmation and the unlocking of the master seed in the rest of this document.*
-
-## Remote interactions
-
-Clef is capable of managing both key-file based accounts as well as hardware wallets. To evaluate clef, we're going to point it to our Rinkeby testnet keystore and specify the Rinkeby chain ID for signing (Clef doesn't have a backing chain, so it doesn't know what network it runs on).
-
-```text

-
-By default, Clef starts up in CLI (Command Line Interface) mode. Arbitrary remote processes may *request* account interactions (e.g. sign a transaction), which the user will need to individually *confirm*.
-
-To test this out, we can *request* Clef to list all account via its *External API endpoint*:
-
-```text
-echo '{"id": 1, "jsonrpc": "2.0", "method": "account_list"}' | nc -U ~/.clef/clef.ipc
-```
-
-This will prompt the user within the Clef CLI to confirm or deny the request:
-

-
-Depending on whether we approve or deny the request, the original NetCat process will get:
-
-```text

-
-or
-
-{"jsonrpc":"2.0","id":1,"error":{"code":-32000,"message":"Request denied"}}
-```
-
-Apart from listing accounts, you can also *request* creating a new account; signing transactions and data; and recovering signatures. You can find the available methods in the Clef [External API Spec](https://github.com/ethereum/go-ethereum/tree/master/cmd/clef#external-api-1) and the [External API Changelog](https://github.com/ethereum/go-ethereum/blob/master/cmd/clef/extapi_changelog.md).
-
-*Note, the number of things you can do from the External API is deliberately small, since we want to limit the power of remote calls by as much as possible! Clef has an [Internal API](https://github.com/ethereum/go-ethereum/tree/master/cmd/clef#ui-api-1) too for the UI (User Interface) which is much richer and can support custom interfaces on top. But that's out of scope here.*
-
-## Automatic rules
-
-For most users, manually confirming every transaction is the way to go. However, there are cases when it makes sense to set up some rules which permit Clef to sign a transaction without prompting the user. One such example would be running a signer on Rinkeby or other PoA networks.
-
-For starters, we can create a rule file that automatically permits anyone to list our available accounts without user confirmation. The rule file is a tiny JavaScript snippet that you can program however you want:
-
-```js
-function ApproveListing() {
-    return "Approve"
-}
-```
-
-Of course, Clef isn't going to just accept and run arbitrary scripts you give it, that would be dangerous if someone changes your rule file! Instead, you need to explicitly *attest* the rule file, which entails injecting its hash into Clef's secure store.

-```
-
-## Under the hood
-
-While doing the operations above, these files have been created:
-
-```text
-$ ls -laR ~/.clef/
-
-$HOME/.clef/:
-total 24
-drwxr-x--x   3 user user  4096 Jul  1 13:45 .

-```
-
-In `$HOME/.clef`, the `masterseed.json` file was created, containing the master seed. This seed was then used to derive a few other things:
-
-- **Vault location**: in this case `02f90c0603f4f2f60188`.
-   - If you use a different master seed, a different vault location will be used that does not conflict with each other (e.g. `clef --signersecret /path/to/file`). This allows you to run multiple instances of Clef, each with its own rules (e.g. mainnet + testnet).
-- **`config.json`**: the encrypted key/value storage for configuration data, currently only containing the key `ruleset_sha256`, the attested hash of the automatic rules to use.
-
-## Advanced rules
-
-In order to make more useful rules - like signing transactions - the signer needs access to the passwords needed to unlock keys from the keystore. You can inject an unlock password via `clef setpw`.
-
-```text
-$ clef setpw 0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3
-
-Please enter a password to store for this address:
-Password:
-Repeat password:
-
-Decrypt master seed of clef
-Password:
-INFO [07-01|14:05:56.031] Credential store updated                 key=0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3
-```
-
-Now let's update the rules to make use of the new credentials:
-
-```js
-function ApproveListing() {
-    return "Approve"
-}
-
-function ApproveSignData(req) {
-    if (req.address.toLowerCase() == "0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3") {
-        if (req.messages[0].value.indexOf("bazonk") >= 0) {
-            return "Approve"
-        }
-        return "Reject"
-    }
-    // Otherwise goes to manual processing
-}
-```
-
-In this example:
-
-- Any requests to sign data with the account `0xd9c9...` will be:
-    - Auto-approved if the message contains `bazonk`,
-    - Auto-rejected if the message does not contain `bazonk`,
-- Any other requests will be passed along for manual confirmation.
-
-*Note, to make this example work, please use you own accounts. You can create a new account either via Clef or the traditional account CLI tools. If the latter was chosen, make sure both Clef and Geth use the same keystore by specifying `--keystore path/to/your/keystore` when running Clef.*
-
-Attest the new rule file so that Clef will accept loading it:
-
-```text
-$ sha256sum rules.js

-
-Restart Clef with the new rules in place:
-
-```

-
-Then test signing, once with `bazonk` and once without:
-
-```
-$ echo '{"id": 1, "jsonrpc":"2.0", "method":"account_signData", "params":["data/plain", "0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3", "0x202062617a6f6e6b2062617a2067617a0a"]}' | nc -U ~/.clef/clef.ipc

-{"jsonrpc":"2.0","id":1,"error":{"code":-32000,"message":"Request denied"}}
-```
-
-Meanwhile, in the Clef output log you can see:
-```text
-INFO [02-21|14:42:41] Op approved
-INFO [02-21|14:42:56] Op rejected
-```
-
-The signer also stores all traffic over the external API in a log file. The last 4 lines shows the two requests and their responses:
-
-```text

-
-For more details on writing automatic rules, please see the [rules spec](https://github.com/ethereum/go-ethereum/blob/master/cmd/clef/rules.md).
-
-## Geth integration
-
-Of course, as awesome as Clef is, it's not feasible to interact with it via JSON RPC by hand. Long term, we're hoping to convince the general Ethereum community to support Clef as a general signer (it's only 3-5 methods), thus allowing your favorite DApp, Metamask, MyCrypto, etc to request signatures directly.
-
-Until then however, we're trying to pave the way via Geth. Geth v1.9.0 has built in support via `--signer <API endpoint>` for using a local or remote Clef instance as an account backend!
-
-We can try this by running Clef with our previous rules on Rinkeby (for now it's a good idea to allow auto-listing accounts, since Geth likes to retrieve them once in a while).
-
-```text
-$ clef --keystore ~/.ethereum/rinkeby/keystore --chainid 4 --rules rules.js
-```
-
-In a different window we can start Geth, list our accounts, even list our wallets to see where the accounts originate from:
-
-```text
-$ geth --rinkeby --signer=~/.clef/clef.ipc console
-
-> eth.accounts
-["0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3", "0x086278a6c067775f71d6b2bb1856db6e28c30418"]
-
-> personal.listWallets
-[{
-    accounts: [{
-        address: "0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3",
-        url: "extapi://$HOME/.clef/clef.ipc"
-    }, {
-        address: "0x086278a6c067775f71d6b2bb1856db6e28c30418",
-        url: "extapi://$HOME/.clef/clef.ipc"
-    }],
-    status: "ok [version=6.0.0]",
-    url: "extapi://$HOME/.clef/clef.ipc"
-}]
-
-> eth.sendTransaction({from: eth.accounts[0], to: eth.accounts[0]})
-```
-
-Lastly, when we requested a transaction to be sent, Clef prompted us in the original window to approve it:
-
-```text
---------- Transaction request-------------
-to:       0xD9C9Cd5f6779558b6e0eD4e6Acf6b1947E7fA1F3
