-## 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.
+

+```
+
+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`.
+
+## TODOs
+
+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.
+
+#### Arguments

+
+### 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.
+
+
+#### Result
+  - raw [data]: signed transaction in RLP encoded form
+  - tx [json]: signed transaction in JSON form

+## 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.
+
+
+#### Sample call
+
+Here's a method invocation:
+```bash
+
+curl -i -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"account_signTransaction","params":[{"from":"0x694267f14675d7e1b9494fd8d72fefe1755710fa","gas":"0x333","gasPrice":"0x1","nonce":"0x0","to":"0x07a565b7ed7d7a678680a4c162885bedbb695fe0", "value":"0x0", "data":"0x4401a6e40000000000000000000000000000000000000000000000000000000000000012"},"safeSend(address)"],"id":67}' http://localhost:8550/

+### ApproveSignData / `ui_approveSignData`
+
+#### Sample call
+
+```json

+  "id": 4,
+  "method": "ui_approveSignData",
+  "params": [
+    {

+
+### ApproveNewAccount / `ui_approveNewAccount`
+
+Invoked when a request for creating a new account has been made.
+
+#### Sample call
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": 4,
+  "method": "ui_approveNewAccount",
+  "params": [
+    {
+      "meta": {
+        "remote": "signer binary",
+        "local": "main",
+        "scheme": "in-proc"
+      }
+    }
+  ]
+}
+```
+
+### ShowInfo / `ui_showInfo`
+
+The UI should show the info (a single message) to the user. Does not expect response.
+
+#### Sample call
+
+```json
+{
+  "jsonrpc": "2.0",
+  "id": 9,
+  "method": "ui_showInfo",
+  "params": [
+    "Tests completed"
+  ]
+}
+
+```
+
+### ShowError / `ui_showError`
+
+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_http": "http://localhost:8550",
+        "extapi_ipc": null,
+        "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|

+## UI Client interface
+
+These data types are defined in the channel between clef and the UI
+### SignDataRequest
+
+SignDataRequest contains information about a pending request to sign some data. The data to be signed can be of various types, defined by content-type. 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

+  }
+}
+```
+### 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",
+      "url": ""
+    }
+  ]
+}
+```
