@eth-optimism/message-relayer

message-relayer is a service that automatically finalizes ("relays") messages sent from Optimism to Ethereum. This package is meant to be used during local development and should NOT be used on a production network.

Installation

Clone, install, and build the Optimism monorepo:

git clone https://github.com/ethereum-optimism/optimism.git
yarn install
yarn build

Running the relayer (Docker)

The message-relayer can be included as part of the local Optimism development environment. Although the message-relayer is not turned on by default, it can be enabled by changing this line in docker-compose.yml to:

replicas: 1

Running the relayer (manual)

The message-relayer can also be run manually. Copy .env.example into a new file named .env, then set the environment variables listed there. Once your environment variables have been set, run the relayer via:

yarn start
