The Arbitrary Message Bridge (AMB) is designed to relay any data between two EVM-based chains. The originating contract encodes data in the form of an arbitrary method call, which can also include or exclude parameters. This information, along with the target contract address, is passed to the AMB contracts. As soon as data are relayed from chain A to chain B by the Arbitrary Message Bridge oracles, the bridge contract on side B passes the ABI-encoded method to the target contract.
