relayer

Relayer

A relayer for the Bridge to watch and sync event between Layer 1 and Taiko Layer 2.

Build the source

Building the taiko-client binary requires a Go compiler. Once installed, run:

make build

Configuration

To run an indexer: run cp .l1processor.example.env .l1processor.env, and replace the variables as needed in .l1processor.env. You need to be running a MySQL instance and a RabbitMQ instance, and replace all the MYSQL_ env vars with yours.

RabbitMQ can be installed with ./scripts/install-rabbitmq.sh.
