Meter Passport - Crosschain Bridge
Meter Passport is a multi-chain router that enables smart contracts to both transfer assets and communicate across blockchains.
The initial implementation of Meter Passport is an enhanced version of ChainSafe bridge based on multi-sig contract secured by five relayers including Protofire, Harshquark, Wetez, InfinityStones, and Meter team.
The next version of Meter Passport V1.5 is currently in extensive testing and audit phase. With this version, the relayers will use Meter Mainnet to reach the consensus on the Proposals. The bridging costs are estimated to be substantially reduced post V1.5 deployment.
