Dev environment configuration

Instructions for launching a bridge instance for developers:

1. Install Rust and Docker.

2. Install Solana CLI: https://docs.solanalabs.com/cli/install

3. Install Anchor: https://www.anchor-lang.com/docs/installation and select version 0.30.1:

avm install 0.30.1
avm use 0.30.1

1. Generate a new keypair: solana-keygen new --no-bip39-passphrase -s -o anchor.json.

2. Install yarn.

3. Run yarn at the project root.

4. Run anchor test to test BTC relay program.

5. Run anchor build && cd block_relayer && cargo test to start E2E tests of all bridge components.

Block relayer

The Block Relayer uses a TOML configuration format. On startup, it attempts to open a config.toml file in its working directory. For detailed configuration options, refer to the example configuration file.

The Block Relayer is a command-line tool with several subcommands:

block-relayer [SUBCOMMAND]

Available subcommands:

• init-deposit: Initialize a BTC deposit to the Relay program's PDA (currently unimplemented)

• init-program: Initialize the BTC relay program on the Yona network

• relay-blocks: Start relaying Bitcoin blocks to the Yona network

• relay-transactions: Start the transaction relaying service

Getting Started

1. Clone the repository:

   git clone https://github.com/your-repo/yona-block-relayer.git
   cd yona-block-relayer

2. Create a config.toml file in the project root directory, using the provided example as a template.

3. Run the desired command:

   cargo run -- [SUBCOMMAND]
