yarn

Building Protos

The generated proto files have been committed for convenience, but if there's ever a change you'll need to re-generate. Steps to regenerate:

• Make sure you have protoc installed on your system
• If any new .proto files were added, update the appropriate ./scripts/gen-*-protos script to include it.
• Run the appropriate yarn gen-* ${PATH_TO_PROTOS} and commit!

Geyser

Note: Mac users may run into an error to the effect of "protoc-gen-js: program not found or is not executable"; if this is thrown, run:

• brew install protobuf@3
• brew link --overwrite protobuf@3
• yarn gen-block-engine ${PATH_TO_BLOCK_ENGINE_PROTOS}
• yarn gen-geyser ${PATH_TO_GEYSER_PROTOS}

Usage

export RPC_URL="https://MY_RPC_URL"
export BLOCK_ENGINE_URL=mainnet.block-engine.jito.wtf
export AUTH_KEYPAIR_PATH=MY_AUTH_KEYPAIR.json
export BUNDLE_TRANSACTION_LIMIT=5
