❎Cross-Chain Layer

Multi-Chain Reach Without Off-Chain Relays

Z4R0’s cross-chain layer enables agents to operate across multiple chains — not by duplicating logic, but by transmitting execution intent between environments in a verifiable, on-chain manner.

This layer integrates LayerZero as its core messaging protocol, supporting secure and gas-efficient inter-chain communication. When an agent on Ethereum needs to trigger execution on Arbitrum or zkSync, it submits a validated message payload through LayerZero’s endpoint. On the receiving chain, a verified execution request is unpacked and processed by the local strategy module.

All messages carry proof-of-origin, eliminating the need for external trust assumptions or custodial bridges. This means agents can coordinate multi-chain actions like capital reallocation, state observation, or conditional execution — all under the same set of agent rules and system constraints.

In future phases, the layer is designed to become IBC-compatible, opening access to Cosmos-native chains and further extending agent interoperability across ecosystems.
