The gateway server implements the CCIP Read (EIP 3668) and responds to requests by searching for names stored on-chain. Once a record is retrieved, it is signed using a predefined key to ensure its validity, and the record and signature are returned to the caller so that they can be provided to the requesting contract, hosted on the mainnet.
It's a simple nodejs server bootstrapped using @chainlink/ccip-read-server. This library adds transparent support for EIP 3668.
Please refer to the .env.example file to know which environment variables are required.
