Replica Guide

To use: You'll want to bring your own more performant RPC URL for the base chain instead of using the default. Configure this via the EN_ETH_CLIENT_URL environment variable in the external-node service in docker-compose.yml. Then run docker compose up.

A number of constants have already been set:

• the chain IDs for L1 (EN_L1_CHAIN_ID: 1 which is ethereum) and L2 (EN_L2_CHAIN_ID: 543210 which is zero network)
• the sequencer http url (EN_MAIN_NODE_URL: https://zero-network.calderachain.xyz/http), which allows for transactions sent to the replica node to be forwarded to the sequencer, effectively meaning you can use the replica node like a full RPC provider

The RPC is exposed via port 3060 (HTTP) and 3061 (websocket) as specified in the docker-compose.yml. After running docker compose up, you may query the RPC as follows:

curl -X POST \
     -H 'Content-Type: application/json' \
     -d '{"jsonrpc":"2.0","id":0,"method":"eth_chainId","params":[]}' \
localhost:3060

{"jsonrpc":"2.0","result":"0x849ea","id":0}

More Notes

• The docker-compose.yml also includes services for prometheus and grafana, but these aren't necessary to spin up
• The postgres user password should probably be changed from the default value (POSTGRES_PASSWORD env variable)
