Version control and key management for Solana programs.

• Automatic versioning of program binaries based on Cargo
• Separation of deployer and authority keys
• Per-cluster configuration
• Reusable and custom program addresses
• (optional) Integration with Anchor IDLs

Install via Cargo like so:

cargo install --git https://github.com/saber-hq/captain --force --locked

Then, in your directory containing your root Cargo.toml, run the following command:

captain init

A Captain workflow works like so:

1. Build your latest programs via captain build
2. Deploy any new programs with captain deploy
3. Upgrade any new programs with captain upgrade

First, build your programs using the command:

captain build

This runs anchor build -v if you have Anchor installed, and cargo build-bpf if you don't have Anchor installed.

Once your new program is ready to be deployed to the blockchain, run:

captain deploy --program <program> --network <network>

where:

• <network> is one of mainnet, devnet, testnet, localnet, or debug
• <program> is the name of your program in the target/deploy/ directory. You can view a list of all available programs using the command captain programs.

This does several things for you:

• Deploys the program
• Sets the deployer of the program to the upgrade_authority of <network> in your Captain.toml file
• If Anchor is installed, uploads the IDLs and sets the authority to the upgrade_authority

If you need to make changes to your program, you can run:

captain upgrade --program <program> --network <network>

This performs the following actions:

• Writes a new program buffer
• Replaces the existing program buffer with this new buffer using the upgrade authority
• (WIP) If Anchor is installed, uploads the new IDL
