Generic Message Passing

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.
