Overview
A messaging protocol is a standard for sending messages between blockchains. It enables cross-chain applications. It is the foundation of interoperability.
How It Works
Messages are relayed between chains via relayers and validated by oracles or validators. Applications use them to coordinate state. This powers omnichain apps.
Why It Matters
Messaging protocols unlock cross-chain applications and liquidity. They are essential to interoperability. Their security is critical.
