Computes the EIP-1014 CREATE2 address from the executing deployer, exact salt, and complete init-code hash. This is deterministic local arithmetic and does not query or mutate chain state.

create2_predict(ADDRESS, BYTES32, BYTES32) # Create2 Prediction Exact Salt Expects salt as exact BYTES32 and init_hash as keccak256(init_code).
| Name | Type | Use |
|---|---|---|
deployer | ADDRESS Address that will execute CREATE2. For factory deployments, this is the factory address, not the future contract owner, transaction caller, or deployer key. | required positional |
salt | BYTES32 All 32 bytes are used exactly in the CREATE2 formula. | required positional |
init_hash | BYTES32 `keccak256(init_code)`, where complete init code is linked creation bytecode plus ABI-encoded constructor arguments. Runtime bytecode hashes are invalid substitutes. | required positional |
| Name | Type |

address | ADDRESS |
Predicted deployment address. Returns keccak256(0xff ++ deployer20 ++ salt32 ++ keccak256(init_code))[12:]. NULL or incorrectly sized raw blobs currently return NULL.
The exact formula is `keccak256(0xff ++ deployer20 ++ salt32 ++ keccak256(init_code))[12:]`.
Prediction is pure address arithmetic. The SQL registration remains VOLATILE despite the deterministic implementation; this is a catalog metadata defect.
create2_predict(ADDRESS, BIGINT, BYTES32) # Create2 Prediction Bigint Salt Converts the signed BIGINT to its lower unsigned 64 bits and left-pads those bytes to salt32. Negative values map modulo 2^64; use BYTES32 when exact or full-width salt bytes matter.

deployer | ADDRESS Address that will execute CREATE2. For factory deployments, this is the factory address, not the future contract owner, transaction caller, or deployer key. | required positional |
salt | BIGINT Signed SQL BIGINT converted to its lower unsigned 64-bit representation and left-padded to 32 bytes. Negative values therefore map modulo 2^64; use BYTES32 for exact or full-width salts. | required positional |
init_hash | BYTES32 `keccak256(init_code)`, where complete init code is linked creation bytecode plus ABI-encoded constructor arguments. Runtime bytecode hashes are invalid substitutes. | required positional |
