multichain-deployment

You can deploy the same protocol address across multiple blockchains using deterministic CREATE2 deployment. This approach applies per-chain configuration and a deployment registry to ensure identical deployment outcomes across chains without manual address tracking.

Deterministic deployment uses the CREATE2 opcode to generate identical contract addresses across multiple blockchains. It requires a deterministic factory and per-chain initialization logic to ensure the same protocol address is deployed repeatably across testnets and mainnets.

You configure per-chain initialization logic using initialize patterns that accept chain-specific configuration. This allows the deployment script to apply unique parameters per blockchain while maintaining the same deterministic contract address through the CREATE2 factory.

Yes, a deployment registry is required to track blockchain addresses and provide auditable deployment records across chains. It records the deployed addresses for cross-chain deployments, ensuring you can verify address equivalence across testnets and mainnets.

You verify address equivalence by executing multi-chain testing workflows after configuring your deterministic CREATE2 factory. These workflows check that the per-chain configuration and initialization logic produce the identical protocol address across the targeted blockchains.
