Messaging Protocols

LayerZero, CCIP.

Beyond Token Bridges

Moving tokens is just the start. Cross-chain messaging protocols let contracts on one chain send arbitrary data and trigger functions on another.

This generalizes bridging into full cross-chain application logic.

What Is a Messaging Protocol?

A messaging protocol is infrastructure that delivers a payload from a source-chain contract to a destination-chain contract, with some security guarantee about authenticity.

Developers build on top of it instead of operating their own validators.
