Meter Passport is the first bridge that supports generic cross chain messaging in production. Ampleforth team uses Meter Passport for both AMPL token transfers and crosschain rebasing. Meter Passport is a fork of ChainSafe's Sygma bridge v2. The generic message-passing interface is the same as the Sygma Bridge. The details of the generic messaging passing can be found in the Sygma bridge documents.
