Create2

Helper to make usage of the CREATE2 EVM opcode easier and safer. CREATE2 can be used to compute in advance the address where a smart contract will be deployed, which allows for interesting new mechanisms known as 'counterfactual interactions'. See the https://eips.ethereum.org/EIPS/eip-1014#motivation[EIP] for more information.

Functions

deploy

*Deploys a contract using CREATE2. The address where the contract will be deployed can be known in advance via computeAddress. The bytecode for a contract can be obtained from Solidity with type(contractName).creationCode. Requirements:

• bytecode must not be empty.
• salt must have not been used for bytecode already.
• the factory must have a balance of at least amount.
• if amount is non-zero, bytecode must have a payable constructor.*

function deploy(uint256 amount, bytes32 salt, bytes memory bytecode) internal returns (address addr);

computeAddress

Returns the address where a contract will be stored if deployed via deploy. Any change in the bytecodeHash or salt will result in a new destination address.

function computeAddress(bytes32 salt, bytes32 bytecodeHash) internal view returns (address);

computeAddress

Returns the address where a contract will be stored if deployed via deploy from a contract located at deployer. If deployer is this contract's address, returns the same value as {computeAddress}.

function computeAddress(bytes32 salt, bytes32 bytecodeHash, address deployer) internal pure returns (address addr);

Errors

Create2EmptyBytecode

There's no code to deploy.
