## Message Relayers

Message Relayers are decentralized or semi-decentralized entities responsible for transporting messages, identity proofs, or transaction data across different blockchain networks. They play a key role in interoperability, ensuring that information from one chain reaches its destination on another chain in a secure and timely manner.

In the context of identity and compliance, relayers might carry the cryptographic proofs needed to verify a user's identity on a remote chain. Because they are responsible for the movement of sensitive data, relayers must be designed to be censorship-resistant and reliable.

They often operate as part of a larger network of validators or as specialized infrastructure providers. The efficiency and security of these relayers directly impact the latency and reliability of cross-chain identity verification and derivative trade execution.

They are a critical layer in the architecture of multi-chain decentralized finance, facilitating the seamless flow of information required for complex financial operations.
