## Go Ethereum
## Swarm
Official Golang implementation of the Ethereum protocol.
[https://swarm.ethereum.org](https://swarm.ethereum.org)
Swarm is a distributed storage platform and content distribution service, a native base layer service of the ethereum web3 stack. The primary objective of Swarm is to provide a decentralized and redundant store for dapp code and data as well as block chain and state data. Swarm is also set out to provide various base layer services for web3, including node-to-node messaging, media streaming, decentralised database services and scalable state-channel infrastructure for decentralised service economies.

## Building the source
For prerequisites and detailed build instructions please read the
[Installation Instructions](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum)
on the wiki.
Building Swarm requires Go (version 1.10 or later).
Building geth requires both a Go (version 1.10 or later) and a C compiler.
You can install them using your favourite package manager.
Once the dependencies are installed, run
go get -d github.com/ethereum/go-ethereum
make geth
go install github.com/ethereum/go-ethereum/cmd/swarm
or, to build the full suite of utilities:
## Running Swarm
make all
Going through all the possible command line flags is out of scope here, but we've enumerated a few common parameter combos to get you up to speed quickly on how you can run your own Swarm node.
## Executables
To run Swarm you need an Ethereum account. You can create a new account by running the following command:
The go-ethereum project comes with several wrappers/executables found in the `cmd` directory.
geth account new
| 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. |
| `puppeth` | a CLI wizard that aids in creating a new Ethereum network. |
You will be prompted for a password:
## Running geth
Your new account is locked with a password. Please give a password. Do not forget this password.
Passphrase:
Repeat passphrase:
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.
Once you have specified the password, the output will be the Ethereum address representing that account. For example:
### Full node on the main Ethereum network
Address: {2f1cd699b0bf461dcfbf0098ad8f5587b038f0f1}
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:
Using this account, connect to Swarm with
swarm --bzzaccount <your-account-here>
# in our example
swarm --bzzaccount 2f1cd699b0bf461dcfbf0098ad8f5587b038f0f1
### Verifying that your local Swarm node is running
When running, Swarm is accessible through an HTTP API on port 8500.
Confirm that it is up and running by pointing your browser to http://localhost:8500
### Ethereum Name Service resolution
The Ethereum Name Service is the Ethereum equivalent of DNS in the classic web. In order to use ENS to resolve names to Swarm content hashes (e.g. `bzz://theswarm.eth`), `swarm` has to connect to a `geth` instance, which is synced with the Ethereum mainnet. This is done using the `--ens-api` flag.
swarm --bzzaccount <your-account-here> \
--ens-api '$HOME/.ethereum/geth.ipc'
# in our example
swarm --bzzaccount 2f1cd699b0bf461dcfbf0098ad8f5587b038f0f1 \
--ens-api '$HOME/.ethereum/geth.ipc'
For more information on usage, features or command line flags, please consult the Documentation.
## Documentation
Swarm documentation can be found at [https://swarm-guide.readthedocs.io](https://swarm-guide.readthedocs.io).
## Developers Guide
### Go Environment
We assume that you have Go v1.10 installed, and `GOPATH` is set.
You must have your working copy under `$GOPATH/src/github.com/ethereum/go-ethereum`.
Most likely you will be working from your fork of `go-ethereum`, let's say from `github.com/nirname/go-ethereum`. Clone or move your fork into the right place:
```
$ geth console
git clone git@github.com:nirname/go-ethereum.git $GOPATH/src/github.com/ethereum/go-ethereum
```
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),
(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`.
### Vendored Dependencies
### A Full node on the Ethereum test network
All dependencies are tracked in the `vendor` directory. We use `govendor` to manage them.
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.
If you want to add a new dependency, run `govendor fetch <import-path>`, then commit the result.
If you want to update all dependencies to their latest upstream version, run `govendor fetch +v`.
### Testing
This section explains how to run unit, integration, and end-to-end tests in your development sandbox.
Testing one library:
```
$ geth --testnet console
go test -v -cpu 4 ./swarm/api
```
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.
Note: Using options -cpu (number of cores allowed) and -v (logging even if no error) is recommended.
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.
Testing only some methods:
```
$ geth --rinkeby console
go test -v -cpu 4 ./eth -run TestMethod
```
### Configuration
Note: here all tests with prefix TestMethod will be run, so if you got TestMethod, TestMethod1, then both!
As an alternative to passing the numerous flags to the `geth` binary, you can also pass a configuration file via:
Running benchmarks:
```
$ geth --config /path/to/your_config.toml
go test -v -cpu 4 -bench . -run BenchmarkJoin
```
To get an idea how the file should look like you can use the `dumpconfig` subcommand to export your existing configuration:
### Profiling Swarm
This section explains how to add Go `pprof` profiler to Swarm
If `swarm` is started with the `--pprof` option, a debugging HTTP server is made available on port 6060.
You can bring up http://localhost:6060/debug/pprof to see the heap, running routines etc.
By clicking full goroutine stack dump (clicking http://localhost:6060/debug/pprof/goroutine?debug=2) you can generate trace that is useful for debugging.
### Metrics and Instrumentation in Swarm
This section explains how to visualize and use existing Swarm metrics and how to instrument Swarm with a new metric.
Swarm metrics system is based on the `go-metrics` library.
The most common types of measurements we use in Swarm are `counters` and `resetting timers`. Consult the `go-metrics` documentation for full reference of available types.
```
$ geth --your-favourite-flags dumpconfig
# incrementing a counter
metrics.GetOrRegisterCounter("network.stream.received_chunks", nil).Inc(1)
# measuring latency with a resetting timer
start := time.Now()
t := metrics.GetOrRegisterResettingTimer("http.request.GET.time"), nil)
...
t := UpdateSince(start)
```
*Note: This works only with geth v1.6.0 and above.*
#### Visualizing metrics
#### Docker quick start
One of the quickest ways to get Ethereum up and running on your machine is by using Docker:
Swarm supports an InfluxDB exporter. Consult the help section to learn about the command line arguments used to configure it:
```
docker run -d --name ethereum-node -v /Users/alice/ethereum:/root \
-p 8545:8545 -p 30303:30303 \
ethereum/client-go
swarm --help | grep metrics
```
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.
We use Grafana and InfluxDB to visualise metrics reported by Swarm. We keep our Grafana dashboards under version control at `./swarm/grafana_dashboards`. You could use them or design your own.
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.
We have built a tool to help with automatic start of Grafana and InfluxDB and provisioning of dashboards at https://github.com/nonsense/stateth , which requires that you have Docker installed.
### Programmatically interfacing Geth nodes
Once you have `stateth` installed, and you have Docker running locally, you have to:
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).
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")
* `--wsorigins` Origins from which to accept websockets requests
* `--ipcdisable` Disable the IPC-RPC server
* `--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!
**Note: Please understand the security implications of opening up an HTTP/WS based transport before
doing so! Hackers on the internet are actively trying to subvert Ethereum nodes with exposed APIs!
Further, all browser tabs can access locally running web servers, so malicious web pages could try to
subvert locally available APIs!**
### 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`):
```json
{
"config": {
"chainId": 0,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"alloc" : {},
"coinbase" : "0x0000000000000000000000000000000000000000",
"difficulty" : "0x20000",
"extraData" : "",
"gasLimit" : "0x2fefd8",
"nonce" : "0x0000000000000042",
"mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00"
}
1. Run `stateth` and keep it running in the background
```
stateth --rm --grafana-dashboards-folder $GOPATH/src/github.com/ethersphere/swarm/grafana_dashboards --influxdb-database metrics
```
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:
```json
"alloc": {
"0x0000000000000000000000000000000000000001": {"balance": "111111111"},
"0x0000000000000000000000000000000000000002": {"balance": "222222222"}
}
2. Run `swarm` with at least the following params:
```
--metrics \
--metrics.influxdb.export \
--metrics.influxdb.endpoint "http://localhost:8086" \
--metrics.influxdb.username "admin" \
--metrics.influxdb.password "admin" \
--metrics.influxdb.database "metrics"
```
With the genesis state defined in the above JSON file, you'll need to initialize **every** Geth node
with it prior to starting it up to ensure all blockchain parameters are correctly set:
3. Open Grafana at http://localhost:3000 and view the dashboards to gain insight into Swarm.
```
$ geth init path/to/genesis.json
```
#### Creating the rendezvous point
## Public Gateways
With all nodes that you want to run initialized to the desired genesis state, you'll need to start a
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:
Swarm offers a local HTTP proxy API that Dapps can use to interact with Swarm. The Ethereum Foundation is hosting a public gateway, which allows free access so that people can try Swarm without running their own node.
```
$ bootnode --genkey=boot.key
$ bootnode --nodekey=boot.key
```
The Swarm public gateways are temporary and users should not rely on their existence for production services.
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.
The Swarm public gateway can be found at https://swarm-gateways.net and is always running the latest `stable` Swarm release.
*Note: You could also use a full-fledged Geth node as a bootnode, but it's the less recommended way.*
## Swarm Dapps
#### Starting up your member nodes
You can find a few reference Swarm decentralised applications at: https://swarm-gateways.net/bzz:/swarmapps.eth
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.
Their source code can be found at: https://github.com/ethersphere/swarm-dapps
```
$ geth --datadir=path/to/custom/data/folder --bootnodes=<bootnode-enode-url-from-above>
```
*Note: Since your network will be completely cut off from the main and test networks, you'll also
need to configure a miner to process transactions and create new blocks for you.*
#### 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.
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:
```
$ geth <usual-flags> --mine --minerthreads=1 --etherbase=0x0000000000000000000000000000000000000000
```
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`).

The other files (including this README) are broken in various ways

- File: empty (file with no content)
- File: swapfile~ (should be skipped)
- File: .hiddenfile (should be skipped)

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.
Check out
* 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
## 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
gendoc Generate documentation about json-rpc format
help Shows a list of commands or help for one command
GLOBAL OPTIONS:

--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, 3=ropsten, 4=rinkeby, 5=Goerli) (default: 1)
--lightkdf Reduce key-derivation RAM & CPU usage at some expense of KDF strength
--nousb Disables monitoring for and managing USB hardware wallets

--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
--help, -h show help
--version, -v print the version
```
Example:
```
signer -keystore /my/keystore -chainid 4
```
## Security model
The security model of the signer 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.
* The 'external' API is considered UNTRUSTED.
* The signer binary 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 `--externalsigner=http://localhost:8550` and would relay requests to `eth.sendTransaction`.
## 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),
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 --external_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/mist/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
The signer listens to HTTP requests on `rpcaddr`:`rpcport`, with the same JSONRPC standard as Geth. The messages are
expected to be JSON [jsonrpc 2.0 standard](http://www.jsonrpc.org/specification).
Some of these call can require user interaction. Clients must be aware that responses
may be delayed significantly or may never be received if a users decides to ignore the confirmation request.
The External API is **untrusted** : it does not accept credentials over this api, nor does it expect
that requests have any authority.
### 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.
An example (insecure) proof-of-concept of has been implemented in `pythonsigner.py`.
The model is as follows:
* The user starts the UI app (`pythonsigner.py`).
* The UI app starts the `signer` with `--stdio-ui`, and listens to the
process output for confirmation-requests.
* The `signer` opens the external http api.
* When the `signer` receives requests, it sends a `jsonrpc` request via `stdout`.
* The UI app prompts the user accordingly, and responds to the `signer`
* The `signer` 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`.
## Methods
### account_new
#### Create new password protected account
The signer will generate a new private key, encrypts it according to [web3 keystore spec](https://github.com/ethereum/wiki/wiki/Web3-Secret-Storage-Definition) and stores 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
None
#### Result
- address [string]: account address that is derived from the generated key
- url [string]: location of the keyfile
#### Sample call
```json
{
"id": 0,
"jsonrpc": "2.0",
"method": "account_new",
"params": []
}
```
Response

}
}
```
### account_list
#### List available accounts
List all accounts that this signer currently manages
#### Arguments
None
#### Result
- array with account records:
- account.address [string]: account address that is derived from the generated key
- account.type [string]: type of the
- account.url [string]: location of the account

}
]
}
```
### account_signTransaction
#### Sign transactions
Signs a transactions and responds with the signed transaction in RLP encoded form.
#### Arguments
2. 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
3. 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
- signed transaction in RLP encoded form [data]

## 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 uses object-based parameters, so that there can be no mixups 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/
```
Results in the following invocation on the UI:
```json

"meta": {
"remote": "signer binary",
"local": "main",
"scheme": "in-proc"
}
}
]
}
```
### ShowInfo / `ui_showInfo`
The UI should show the info to the user. Does not expect response.
#### Sample call
```json
{
"jsonrpc": "2.0",
"id": 9,
"method": "ui_showInfo",
"params": [
{
"text": "Tests completed"
}
]
}
```
### ShowError / `ui_showError`
The UI should show the info to the user. Does not expect response.
```json
{
"jsonrpc": "2.0",
"id": 2,
"method": "ShowError",
"params": [
{
"text": "Testing 'ShowError'"
}
]
}
```
### 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`.
### OnSignerStartup / `ui_onSignerStartup`
This method provide the UI with information about what API version the signer uses (both internal and external) aswell 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"
}
}
]
}
```
### 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 approproate 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.

## 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 presentthe user with the contents of the `message`
Example:
```json
{
"content_type": "text/plain",
"address": "0xDEADbEeF000000000000000000000000DeaDbeEf",
"raw_data": "GUV0aGVyZXVtIFNpZ25lZCBNZXNzYWdlOgoxMWhlbGxvIHdvcmxk",
"message": [
{
"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 aswell"
}
],
"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",
"s": "0x4e8a4ebfff434e971e0ef12c5bf3a881b06fd04fc3f8b8a7291fb67a26a1d4ed",
"hash": "0x662f6d772692dd692f1b5e8baa77a9ff95bbd909362df3fc3d301aafebde5441"
}
}
```
### 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": ""
}
]
}
```
