The Transceiver is intended to offer a protocol-agnostic interface for sending and receiving cross-chain messages. For Native Token Transfers, this entails initiating attestation generation on the source chain, verifying the resulting attestation on the destination chain, and delivering the message to the associated NttManager.
In the provided implementations (EVM/SVM), Transceiver are intended to have a many-to-one or one-to-one relationship with Managers.
NttManager message emitted by a Transceiver implementation. Each message includes a Transceiver-specified 4-byte prefix. This should be a constant value, set by a protocol-specific Transceiver implementation, that identifies the payload as an NTT Transceiver emitted payload.
