|
||||
> **⚠️ IMPORTANT DISCLAIMER: ALPHA SOFTWARE**
|
||||
>
|
||||
> Ark is currently in alpha stage. This software is experimental and under active development.
|
||||
> **DO NOT ATTEMPT TO USE IN PRODUCTION**. Use at your own risk.
|
||||
|
||||
- [`server`](./server/) always-on daemon that serves as the Ark Service Provider (ASP)
|
||||
- [`client`](./client/) single-key wallet as command-line interface (CLI) to interact with the ASP
|
||||
## Repository Structure
|
||||
|
||||
Refer to the README in each directory for more information about development.
|
||||
- [`server`](./server/): `arkd` Ark Service Provider (ASP) - the always-on daemon
|
||||
- [`client`](./client/): `ark` Single-key wallet CLI for interacting with the ASP
|
||||
- [`common`](./common/): Shared code between the server and client
|
||||
- [`pkg/client-sdk`](./pkg/client-sdk/): Go SDK for interacting with ASPs running the Ark protocol. It offers WASM bindings to interact with the SDK from the browser and other environments.

|

## Usage Documentation
|
||||
|
||||
### Covenant-less Ark
|
||||
For a comprehensive guide on how to set up and use Ark, please visit our [Developer Portal](https://arkdev.info).
|
||||
For a quick-start with Docker, head over to our [Quick Start guide](https://arkdev.info/docs/quick-start/intro) where you can setup an Ark Server and Clients in a local Bitcoin regtest network.
|
||||
|
||||
#### Run the daemon (regtest)
|
||||
## Development
|
||||
|
||||
Run locally with [Docker](https://docs.docker.com/engine/install/) and [Nigiri](https://nigiri.vulpem.com/).
|
||||
For detailed development instructions, including building from source, running tests, and contributing guidelines, please refer to the README files in the `server` and `client` directories.
|
||||
|
||||
### Contributing Guidelines
|
||||
|
||||
1. **No force pushing in PRs**: Always use `git push --force-with-lease` to avoid overwriting others' work.
|
||||
2. **Sign your commits**: Use GPG to sign your commits for verification.
|
||||
3. **Squash and merge**: When merging PRs, use the "Squash and merge" option to maintain a clean commit history.
|
||||
4. **Testing**: Add tests for each new major feature or bug fix.
|
||||
5. **Keep master green**: The master branch should always be in a passing state. All tests must pass before merging.
|
||||
|
||||
### Local Development Setup
|
||||
|
||||
1. Install Go (version 1.18 or later)
|
||||
2. Install [Nigiri](https://nigiri.vulpem.com/) for local Bitcoin and Liquid networks
|
||||
3. Clone this repository:
|
||||
```
|
||||
nigiri start
|
||||
docker compose -f ./docker-compose.clark.regtest.yml up -d
|
||||
git clone https://github.com/ark-network/ark.git
|
||||
cd ark
|
||||
```
|
||||
4. Install dependencies:
|
||||
```
|
||||
go mod download
|
||||
```
|
||||
5. Build the project:
|
||||
```
|
||||
cd server
|
||||
make build
|
||||
cd ../client
|
||||
make build
|
||||
```
|
||||
|
||||
the compose file will start a `clarkd` container exposing Ark API on localhost:6000.
|
||||
Note: You need to run `make build` in both the `server` and `client` directories separately.
|
||||
|
||||
#### Fund the embedded wallet
|
||||
## Support
|
||||
|
||||
The ASP needs funds to operate. the `v1/admin/address` allows to generate a new address. This endpoint is protected by Basic Authorization token.
|
||||
If you encounter any issues or have questions, please file an issue on our [GitHub Issues](https://github.com/ark-network/ark/issues) page.
|
||||
|
||||
```
|
||||
curl http://localhost:6000/v1/admin/address -H 'Authorization: Basic YWRtaW46YWRtaW4='
|
||||
```
|
||||
## Security
|
||||
|
||||
> This exemple is using the default USER/PASSWORD credentials. You can customize them by setting the `ARK_AUTH_USER` and `ARK_AUTH_PASS` variables.
|
||||
We take the security of Ark seriously. If you discover a security vulnerability, we appreciate your responsible disclosure.
|
||||
|
||||
Faucet the address using nigiri
|
||||
Currently, we do not have an official bug bounty program. However, we value the efforts of security researchers and will consider offering appropriate compensation for significant, [responsibly disclosed vulnerabilities](./SECURITY.md).
|
||||
|
||||
```
|
||||
nigiri faucet <ASP_address>
|
||||
```
|
||||
|
||||
### Ark with covenants (Liquid only)
|
||||
|
||||
#### Setup the Ocean wallet
|
||||
|
||||
Run locally with Docker on Liquid Testnet. It uses `docker-compose` to build the `arkd` docker image from `server` and run the it as container, together with the `oceand` container.
|
||||
|
||||
Start `oceand` in Liquid Testnet:
|
||||
|
||||
```bash
|
||||
docker compose up -d oceand
|
||||
```
|
||||
|
||||
Setup `oceand`:
|
||||
|
||||
```bash
|
||||
alias ocean='docker exec oceand ocean'
|
||||
ocean config init --no-tls
|
||||
ocean wallet create --password <password>
|
||||
ocean wallet unlock --password <password>
|
||||
```
|
||||
|
||||
#### Run `arkd` connected to Ocean
|
||||
|
||||
Start the ASP
|
||||
|
||||
```bash
|
||||
docker compose up -d arkd
|
||||
```
|
||||
|
||||
**Note:** On startup `arkd` will create an account `ark` on oceand.
|
||||
|
||||
Get an address from Ocean to add funds to the ASP:
|
||||
|
||||
```bash
|
||||
ocean account derive --account-name ark
|
||||
```
|
||||
|
||||
Fund the resulting address with [Liquid testnet faucet](https://liquidtestnet.com/faucet).
|
||||
|
||||
Check the balance of the `ark` account:
|
||||
|
||||
```bash
|
||||
ocean account --account-name=ark balance
|
||||
```
|
||||
|
||||
### Ark client
|
||||
|
||||
Inside the `arkd` container is shipped the `ark` CLI. You can submit payment to the ASP using the `ark` CLI.
|
||||
|
||||
```bash
|
||||
alias ark='docker exec -it arkd ark'
|
||||
ark init --password <password> --ark-url localhost:8080
|
||||
```
|
||||
|
||||
This will add a `state.json` file to the following directory:
|
||||
|
||||
- POSIX (Linux/BSD): ~/.Ark-cli
|
||||
- Mac OS: $HOME/Library/Application Support/Ark-cli
|
||||
- Windows: %LOCALAPPDATA%\Ark-cli
|
||||
- Plan 9: $home/Ark-cli
|
||||
|
||||
**Note:** you can use a different datadir by exporting the env var `ARK_WALLET_DATADIR` like:
|
||||
|
||||
```bash
|
||||
export ARK_WALLET_DATADIR=path/to/custom
|
||||
ark init --password <password> --ark-url localhost:8080 --network testnet
|
||||
```
|
||||
|
||||
Add funds to the ark wallet:
|
||||
|
||||
```bash
|
||||
ark receive
|
||||
{
|
||||
"offchain_address": <address starting with "tark1q...">,
|
||||
"onchain_address": <address starting with "tex1q...">
|
||||
}
|
||||
```
|
||||
|
||||
Fund the `onchain_address` with https://liquidtestnet.com/faucet.
|
||||
|
||||
Onboard the ark:
|
||||
|
||||
```bash
|
||||
ark onboard --amount 21000
|
||||
```
|
||||
|
||||
After confirmation, ark wallet will be funded and ready to spend offchain.
|
||||
|
||||
In **another tab**, setup another ark wallet with:
|
||||
|
||||
```bash
|
||||
export ARK_WALLET_DATADIR=./datadir
|
||||
alias ark2=$(pwd)/build/ark-<os>-<arch>
|
||||
ark2 init --password <password> --ark-url localhost:8080 --network testnet
|
||||
```
|
||||
|
||||
**Note:** `ark2` should always run in the second tab.
|
||||
|
||||
### Make payments
|
||||
|
||||
You can now make ark payments between the 2 ark wallets:
|
||||
|
||||
```bash
|
||||
ark2 receive
|
||||
{
|
||||
"offchain_address": <address starting with "tark1q...">,
|
||||
"onchain_address": <address starting with "tex1q...">,
|
||||
"relays": ["localhost:8080"]
|
||||
}
|
||||
```
|
||||
|
||||
```bash
|
||||
ark send --to <ark2 offchain address> --amount 2100
|
||||
```
|
||||
|
||||
Both balances should reflect the payment:
|
||||
|
||||
```bash
|
||||
ark balance
|
||||
{
|
||||
"offchain_balance": 18900,
|
||||
"onchain_balance": 0
|
||||
}
|
||||
```
|
||||
|
||||
```bash
|
||||
ark2 balance
|
||||
{
|
||||
"offchain_balance": 2100,
|
||||
"onchain_balance": 0
|
||||
}
|
||||
```
|
||||
|
||||
### Exiting
|
||||
|
||||
User `ark` can leave the ark collaboratively (i.e. ASP needs to collaborate):
|
||||
|
||||
```bash
|
||||
ark redeem --address <onchain_address> --amount 12100
|
||||
```
|
||||
|
||||
In the case of the ASP is not responding, you can leave the ark unilaterally (`--amount` is not necessary since `--force` will redeem all funds):
|
||||
|
||||
```bash
|
||||
ark redeem --force
|
||||
```
|
||||
|
||||
### Help
|
||||
|
||||
You can see all available commands with `help`:
|
||||
|
||||
```bash
|
||||
ark help
|
||||
```
