CREATE2 address

Deployer addressSalt (bytes32)Init code / bytecode (hex)

About this tool

CREATE2 lets factories deploy to a predetermined address from deployer + salt + init code. Common for cross-chain twins and permissionless factories.

All computation happens locally in your browser. No inputs are sent to a server.

Factories

OpenZeppelin-style factory patterns and counterfactual wallets rely on CREATE2. Salt carefully — colliding salts with different bytecode still produce different addresses, but reuse of the same init code + salt is a replay surface.
