The fault-detector is a simple service for detecting discrepancies between your local view of the Mantle network and the L2 output proposals published to Ethereum.
Clone, install, and build the Optimism monorepo:
git clone https://github.com/mantlenetworkio/mantle.git
yarn install
yarn build
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 service via:
yarn start
