## Executables
The go-ethereum project comes with several wrappers/executables found in the `cmd` directory.
The go-ethereum project comes with several wrappers/executables found in the `cmd`
directory.
| Command | Description |
|:----------:|-------------|
| **`geth`** | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default), archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as a gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. `geth --help` and the [CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) for command line options. |
| `abigen` | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However, it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. |
| `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks. |
| `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow isolated, fine-grained debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). |
| `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs. Please see the [test suite's readme](https://github.com/ethereum/rpc-tests/blob/master/README.md) for details. |
| `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ethereum/wiki/wiki/RLP)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user-friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`). |
| `swarm` | Swarm daemon and tools. This is the entry point for the Swarm network. `swarm --help` for command line options and subcommands. See [Swarm README](https://github.com/ethereum/go-ethereum/tree/master/swarm) for more information. |

## Running geth
## Running `geth`
Going through all the possible command line flags is out of scope here (please consult our
[CLI Wiki page](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options)), but we've
enumerated a few common parameter combos to get you up to speed quickly on how you can run your
own Geth instance.

### Full node on the main Ethereum network
By far the most common scenario is people wanting to simply interact with the Ethereum network:
create accounts; transfer funds; deploy and interact with contracts. For this particular use-case
the user doesn't care about years-old historical data, so we can fast-sync quickly to the current
state of the network. To do so:

particular use-case the user doesn't care about years-old historical data, so we can
fast-sync quickly to the current state of the network. To do so:
```
```shell
$ geth console
```
This command will:
* Start geth in fast sync mode (default, can be changed with the `--syncmode` flag), causing it to
download more data in exchange for avoiding processing the entire history of the Ethereum network,
which is very CPU intensive.
* Start up Geth's built-in interactive [JavaScript console](https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console),
* Start `geth` in fast sync mode (default, can be changed with the `--syncmode` flag),
causing it to download more data in exchange for avoiding processing the entire history
of the Ethereum network, which is very CPU intensive.
* Start up `geth`'s built-in interactive [JavaScript console](https://github.com/ethereum/go-ethereum/wiki/JavaScript-Console),
(via the trailing `console` subcommand) through which you can invoke all official [`web3` methods](https://github.com/ethereum/wiki/wiki/JavaScript-API)
as well as Geth's own [management APIs](https://github.com/ethereum/go-ethereum/wiki/Management-APIs).
This tool is optional and if you leave it out you can always attach to an already running Geth instance
with `geth attach`.

### A Full node on the Ethereum test network
Transitioning towards developers, if you'd like to play around with creating Ethereum contracts, you
almost certainly would like to do that without any real money involved until you get the hang of the
entire system. In other words, instead of attaching to the main network, you want to join the **test**
network with your node, which is fully equivalent to the main network, but with play-Ether only.

```
```shell

The `console` subcommand has the exact same meaning as above and they are equally useful on the
testnet too. Please see above for their explanations if you've skipped here.

Specifying the `--testnet` flag, however, will reconfigure your `geth` instance a bit:
* Instead of using the default data directory (`~/.ethereum` on Linux for example), Geth will nest
itself one level deeper into a `testnet` subfolder (`~/.ethereum/testnet` on Linux). Note, on OSX
and Linux this also means that attaching to a running testnet node requires the use of a custom
endpoint since `geth attach` will try to attach to a production node endpoint by default. E.g.
`geth attach <datadir>/testnet/geth.ipc`. Windows users are not affected by this.
* Instead of connecting the main Ethereum network, the client will connect to the test network,
which uses different P2P bootnodes, different network IDs and genesis states.

*Note: Although there are some internal protective measures to prevent transactions from crossing
over between the main network and test network, you should make sure to always use separate accounts
for play-money and real-money. Unless you manually move accounts, Geth will by default correctly
separate the two networks and will not make any accounts available between them.*

### Full node on the Rinkeby test network
The above test network is a cross-client one based on the ethash proof-of-work consensus algorithm. As such, it has certain extra overhead and is more susceptible to reorganization attacks due to the network's low difficulty/security. Go Ethereum also supports connecting to a proof-of-authority based test network called [*Rinkeby*](https://www.rinkeby.io) (operated by members of the community). This network is lighter, more secure, but is only supported by go-ethereum.

```shell
docker run -d --name ethereum-node -v /Users/alice/ethereum:/root \
-p 8545:8545 -p 30303:30303 \
ethereum/client-go
```
This will start geth in fast-sync mode with a DB memory allowance of 1GB just as the above command does. It will also create a persistent volume in your home directory for saving your blockchain as well as map the default ports. There is also an `alpine` tag available for a slim version of the image.

Do not forget `--rpcaddr 0.0.0.0`, if you want to access RPC from other containers and/or hosts. By default, `geth` binds to the local interface and RPC endpoints is not accessible from the outside.

### Programmatically interfacing Geth nodes
### Programmatically interfacing `geth` nodes
As a developer, sooner rather than later you'll want to start interacting with Geth and the Ethereum
network via your own programs and not manually through the console. To aid this, Geth has built-in
support for a JSON-RPC based APIs ([standard APIs](https://github.com/ethereum/wiki/wiki/JSON-RPC) and
[Geth specific APIs](https://github.com/ethereum/go-ethereum/wiki/Management-APIs)). These can be
exposed via HTTP, WebSockets and IPC (UNIX sockets on UNIX based platforms, and named pipes on Windows).

These can be exposed via HTTP, WebSockets and IPC (UNIX sockets on UNIX based

The IPC interface is enabled by default and exposes all the APIs supported by Geth, whereas the HTTP
and WS interfaces need to manually be enabled and only expose a subset of APIs due to security reasons.
These can be turned on/off and configured as you'd expect.

HTTP based JSON-RPC API options:
* `--rpc` Enable the HTTP-RPC server
* `--rpcaddr` HTTP-RPC server listening interface (default: "localhost")
* `--rpcport` HTTP-RPC server listening port (default: 8545)

* `--rpcapi` API's offered over the HTTP-RPC interface (default: `eth,net,web3`)
* `--rpccorsdomain` Comma separated list of domains from which to accept cross origin requests (browser enforced)
* `--ws` Enable the WS-RPC server
* `--wsaddr` WS-RPC server listening interface (default: "localhost")
* `--wsport` WS-RPC server listening port (default: 8546)
* `--wsapi` API's offered over the WS-RPC interface (default: "eth,net,web3")

* `--ipcapi` API's offered over the IPC-RPC interface (default: "admin,debug,eth,miner,net,personal,shh,txpool,web3")
* `--ipcapi` API's offered over the IPC-RPC interface (default: `admin,debug,eth,miner,net,personal,shh,txpool,web3`)
* `--ipcpath` Filename for IPC socket/pipe within the datadir (explicit paths escape it)
You'll need to use your own programming environments' capabilities (libraries, tools, etc) to connect
via HTTP, WS or IPC to a Geth node configured with the above flags and you'll need to speak [JSON-RPC](https://www.jsonrpc.org/specification)
on all transports. You can reuse the same connection for multiple requests!

### Operating a private network
Maintaining your own private network is more involved as a lot of configurations taken for granted in
the official networks need to be manually set up.

#### Defining the private genesis state
First, you'll need to create the genesis state of your networks, which all nodes need to be aware of
and agree upon. This consists of a small JSON file (e.g. call it `genesis.json`):

The above fields should be fine for most purposes, although we'd recommend changing the `nonce` to
some random value so you prevent unknown remote nodes from being able to connect to you. If you'd
like to pre-fund some accounts for easier testing, you can populate the `alloc` field with account
configs:

bootstrap node that others can use to find each other in your network and/or over the internet. The
clean way is to configure and run a dedicated bootnode:

the internet. The clean way is to configure and run a dedicated bootnode:
```
```shell
$ bootnode --genkey=boot.key
$ bootnode --nodekey=boot.key
```
With the bootnode online, it will display an [`enode` URL](https://github.com/ethereum/wiki/wiki/enode-url-format)
that other nodes can use to connect to it and exchange peer information. Make sure to replace the
displayed IP address information (most probably `[::]`) with your externally accessible IP to get the
actual `enode` URL.

*Note: You could also use a full-fledged Geth node as a bootnode, but it's the less recommended way.*

#### Starting up your member nodes
With the bootnode operational and externally reachable (you can try `telnet <ip> <port>` to ensure
it's indeed reachable), start every subsequent Geth node pointed to the bootnode for peer discovery
via the `--bootnodes` flag. It will probably also be desirable to keep the data directory of your
private network separated, so do also specify a custom `--datadir` flag.

#### Running a private miner
Mining on the public Ethereum network is a complex task as it's only feasible using GPUs, requiring
an OpenCL or CUDA enabled `ethminer` instance. For information on such a setup, please consult the
[EtherMining subreddit](https://www.reddit.com/r/EtherMining/) and the [Genoil miner](https://github.com/Genoil/cpp-ethereum)
repository.

and the [Genoil miner](https://github.com/Genoil/cpp-ethereum) repository.
In a private network setting, however a single CPU miner instance is more than enough for practical
purposes as it can produce a stable stream of blocks at the correct intervals without needing heavy
resources (consider running on a single thread, no need for multiple ones either). To start a Geth
instance for mining, run it with all your usual flags, extended by:

Which will start mining blocks and transactions on a single CPU thread, crediting all proceedings to
the account specified by `--etherbase`. You can further tune the mining by changing the default gas
limit blocks converge to (`--targetgaslimit`) and the price transactions are accepted at (`--gasprice`).

# Using the smartcard wallet
## Requirements
* A USB smartcard reader
* A keycard that supports the status app
* PCSCD version 4.3 running on your system **Only version 4.3 is currently supported**
## Preparing the smartcard
**WARNING: FOILLOWING THESE INSTRUCTIONS WILL DESTROY THE MASTER KEY ON YOUR CARD. ONLY PROCEED IF NO FUNDS ARE ASSOCIATED WITH THESE ACCOUNTS**
You can use status' [keycard-cli](https://github.com/status-im/keycard-cli) and you should get _at least_ version 2.1.1 of their [smartcard application](https://github.com/status-im/status-keycard/releases/download/2.2.1/keycard_v2.2.1.cap)
You also need to make sure that the PCSC daemon is running on your system.
Then, you can install the application to the card by typing:
```
keycard install -a keycard_v2.2.1.cap && keycard init
```
At the end of this process, you will be provided with a PIN, a PUK and a pairing password. Write them down, you'll need them shortly.
Start `geth` with the `console` command. You will notice the following warning:
```
WARN [04-09|16:58:38.898] Failed to open wallet url=keycard://044def09 err="smartcard: pairing password needed"
```
Write down the URL (`keycard://044def09` in this example). Then ask `geth` to open the wallet:
```
> personal.openWallet("keycard://044def09")
Please enter the pairing password:
```
Enter the pairing password that you have received during card initialization. Same with the PIN that you will subsequently be
asked for.
If everything goes well, you should see your new account when typing `personal` on the console:
```
> personal
WARN [04-09|17:02:07.330] Smartcard wallet account derivation failed url=keycard://044def09 err="Unexpected response status Cla=0x80, Ins=0xd1, Sw=0x6985"
{
listAccounts: [],
listWallets: [{
status: "Empty, waiting for initialization",
url: "keycard://044def09"
}],
...
}
```
So the communication with the card is working, but there is no key associated with this wallet. Let's create it:
```
> personal.initializeWallet("keycard://044def09")
"tilt ... impact"
```
You should get a list of words, this is your seed so write them down. Your wallet should now be initialized:
```
> personal.listWallets
[{
accounts: [{
address: "0x678b7cd55c61917defb23546a41803c5bfefbc7a",
url: "keycard://044d/m/44'/60'/0'/0/0"
}],
status: "Online",
url: "keycard://044def09"
}]
```
You're all set!
## Usage
1. Start `geth` with the `console` command
2. Check the card's URL by checking `personal.listWallets`:
```
listWallets: [{
status: "Online, can derive public keys",
url: "keycard://a4d73015"
}]
```
3. Open the wallet, you will be prompted for your pairing password, then PIN:
```
personal.openWallet("keycard://a4d73015")
```
4. Check that creation was successful by typing e.g. `personal`. Then use it like a regular wallet.
## Known issues
* Starting geth with a valid card seems to make firefox crash.
* PCSC version 4.4 should work, but is currently untested

//
// 1. (First use with a given client) Establish a pairing between hardware
// wallet and client. This requires a secret value called a 'pairing password'.
// You can pair with an unpaired wallet with `personal.openWallet(URI, pairing password)`.
// 2. (First use only) Initialize the wallet, which generates a keypair, stores
// it on the wallet, and returns it so the user can back it up. You can
// initialize a wallet with `personal.initializeWallet(URI)`.
// 3. Connect to the wallet using the pairing information established in step 1.
// You can connect to a paired wallet with `personal.openWallet(URI, PIN)`.
// 4. Interact with the wallet as normal.

// Before you touch the protocol files, you need to be aware of a breaking change
// that occurred between firmware versions 1.7.3->1.8.0 (Model One) and 2.0.10->
// 2.1.0 (Model T). The Ethereum address representation was changed from the 20
// byte binary blob to a 42 byte hex string. The upstream protocol buffer files
// only support the new format, so blindly pulling in a new spec will break old
// devices!
//
// The Trezor devs had the foresight to add the string version as a new message
// code instead of replacing the binary one. This means that the proto file can
// actually define both the old and the new versions as optional. Please ensure
// that you add back the old addresses everywhere (to avoid name clash. use the
// addressBin and addressHex names).
//
// If in doubt, reach out to @karalabe.
// Package trezor contains the wire protocol wrapper in Go.
// To regenerate the protocol files in this package:
// - Download the latest protoc https://github.com/protocolbuffers/protobuf/releases

Clef
----
Clef can be used to sign transactions and data and is meant as a replacement for geth's account management.
This allows DApps not to depend on geth's account management. When a DApp wants to sign data it can send the data to
the signer, the signer will then provide the user with context and asks the user for permission to sign the data. If
the users grants the signing request the signer 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 a remote node because a local Ethereum node is not available, not
synchronised with the chain or a particular Ethereum node that has no built-in (or limited) account management.
Clef can run as a daemon on the same machine, or off a usb-stick like [usb armory](https://inversepath.com/usbarmory),
or a separate VM in a [QubesOS](https://www.qubes-os.org/) type os setup.
# Clef
Check out
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 asks for permission to sign the content. If the users grants the signing request, Clef will send the signature back to the DApp.
* the [tutorial](tutorial.md) for some concrete examples on how the signer works.
* the [setup docs](docs/setup.md) for some information on how to configure it to work on QubesOS or USBArmory.
* the [data types](datatypes.md) for detailed information on the json types used in the communication between
clef and an external UI
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 synchronised 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 infos 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.

## Security model
The security model of the signer is as follows:
The security model of Clef is as follows:
* One critical component (the signer binary / daemon) is responsible for handling cryptographic operations: signing, private keys, encryption/decryption of keystore files.
* The signer binary has a well-defined 'external' API.
* 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.
* The signer binary also communicates with whatever process that invoked the binary, via stdin/stdout.
* 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:
The general flow for signing a transaction using e.g. Geth is as follows:

## TODOs
Some snags and todos
* [ ] The signer 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 the signer 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 the signer 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".
* [x] It should be possible to configure the signer to auto-allow listing (certain) accounts, instead of asking every time.
* [x] Done Upon startup, the signer should spit out some info to the caller (particularly important when executed in `stdio-ui`-mode),

### UI API
### Internal UI API
The signer 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 the
`stdin`/`stdout` for the UI-api.

## Initializing the signer
## Initializing Clef
First, initialize the master seed.
First thing's 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
#./signer init
$ clef init
WARNING!
The signer is alpha software, and not yet publically released. This software has _not_ been audited, and there
are no guarantees about the workings of this software. It may contain severe flaws. You should not use this software
unless you agree to take full responsibility for doing so, and know what you are doing.
Clef is an account management tool. It may, like any software, contain bugs.
TLDR; THIS IS NOT PRODUCTION-READY SOFTWARE!
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;

This is required to be able to store credentials, such as :
The master seed of clef will be locked with a password.
Please specify a password. Do not forget this password!

* Storage for JavaScript auto-signing rules
* Hash of JavaScript rule-file
You should treat that file with utmost secrecy, and make a backup of it.
NOTE: This file does not contain your accounts. Those need to be backed up separately!

## Creating rules
## Remote interactions
Now, you can create a rule-file. Note that it is not mandatory to use predefined rules, but it's really handy.
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).
```javascript
function ApproveListing(){
```text
$ clef --keystore ~/.ethereum/rinkeby/keystore --chainid 4
INFO [07-01|11:00:46.385] Starting signer chainid=4 keystore=$HOME/.ethereum/rinkeby/keystore light-kdf=false advanced=false

```
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:
```text
-------- List Account request--------------
A request has been made to list all accounts.
You can select which accounts the caller can see
[x] 0xD9C9Cd5f6779558b6e0eD4e6Acf6b1947E7fA1F3

-------------------------------------------
Request context:
NA -> NA -> NA
Additional HTTP header data, provided by the external caller:
User-Agent:

```
Depending on whether we approve or deny the request, the original NetCat process will get:
```text
{"jsonrpc":"2.0","id":1,"result":["0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3","0x086278a6c067775f71d6b2bb1856db6e28c30418"]}
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"
}
```
Get the `sha256` hash. If you have openssl, you can do `openssl sha256 rules.js`...
```text
#sha256sum rules.js
6c21d1737429d6d4f2e55146da0797782f3c0a0355227f19d702df377c165d72 rules.js
```
...now `attest` the file...
```text
#./signer attest 6c21d1737429d6d4f2e55146da0797782f3c0a0355227f19d702df377c165d72
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.

In `~/.signer`, the `secrets.dat` file was created, containing the `master_seed`.
The `master_seed` was then used to derive a few other things:
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 `43f73718397aa54d1b22` .
- Thus, if you use a different `master_seed`, another `vault_location` will be used that does not conflict with each other.
- Example: `signer --signersecret /path/to/afile ...`
- `config.json` which is the encrypted key/value storage for configuration data, containing the key `ruleset_sha256`.
- **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
## Adding credentials
In order to make more useful rules like signing transactions, the signer needs access to the passwords needed to unlock keystores.
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
#./signer addpw "0x694267f14675d7e1b9494fd8d72fefe1755710fa" "test_password"
$ clef setpw 0xd9c9cd5f6779558b6e0ed4e6acf6b1947e7fa1f3

```
## More advanced rules
Now let's update the rules to make use of credentials:
Now let's update the rules to make use of the new credentials:
```javascript
function ApproveListing(){
```js
function ApproveListing() {
return "Approve"
}
function ApproveSignData(r){
if( r.address.toLowerCase() == "0x694267f14675d7e1b9494fd8d72fefe1755710fa")
{
if(r.message.indexOf("bazonk") >= 0){
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 `0x694...` will be
* auto-approved if the message contains with `bazonk`
* auto-rejected if it does not.
* Any other signing-requests will be passed along for manual approve/reject.
_Note: make sure that `0x694...` is an account you have access to. You can create it either via the clef or the traditional account cli tool. If the latter was chosen, make sure both clef and geth use the same keystore by specifing `--keystore path/to/your/keystore` when running clef._
- 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 specifing `--keystore path/to/your/keystore` when running Clef.*
Attest the new rule file so that Clef will accept loading it:

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
from: 0xD9C9Cd5f6779558b6e0eD4e6Acf6b1947E7fA1F3 [chksum ok]
value: 0 wei
gas: 0x5208 (21000)
gasprice: 1000000000 wei
nonce: 0x2366 (9062)
Request context:
NA -> NA -> NA
Additional HTTP header data, provided by the external caller:
User-Agent:
Origin:
-------------------------------------------
Approve? [y/N]:
> y
```
:boom:
*Note, if you enable the external signer backend in Geth, all other account management is disabled. This is because long term we want to remove account management from Geth.*
