Create2Deployer

0x4e59b44847b379578588920cA78FbF26c0B4956C

Can be used to deploy contracts with CREATE2 Factory.

State Variables

CREATE2_FACTORY

_Used by default when deploying with create2, https://github.com/Arachnid/deterministic-deployment-proxy._

address public constant _CREATE2_FACTORY = 0x4e59b44847b379578588920cA78FbF26c0B4956C;

Functions

deployWithCreate2

Deploys a contract using the _CREATE2_FACTORY.

The call data is encoded as abi.encodePacked(salt, initCode).

The return data is abi.encodePacked(addr).

function deployWithCreate2(uint256 salt, bytes memory initCode) internal returns (address addr);

Parameters

Name	Type	Description
salt	uint256	The salt to use for the deployment.
initCode	bytes	The init code of the contract to deploy.

Returns

Name	Type	Description
addr	address	The address of the deployed contract.

deployWithCreate2IfNecessary

Deploys a contract using the _CREATE2_FACTORY if it hasn't been deployed yet.

function deployWithCreate2IfNecessary(uint256 salt, bytes memory initCode) internal returns (address addr);

getCreate2Address

Returns the deterministic address of a contract for the given salt and init code.

Assumes that the contract will be deployed using deployWithCreate2.

function getCreate2Address(uint256 salt, bytes memory initCode) internal pure returns (address);

Parameters

Name	Type	Description
salt	uint256	The salt to use for the deployment.
initCode	bytes	The init code of the contract to deploy.

Returns

Name	Type	Description
<none>	address	addr The address of the deployed contract.

getCreate2Address

Returns the deterministic address of a contract for the given salt and init code.

Assumes that the contract will be deployed using deployWithCreate2.

function getCreate2Address(uint256 salt, bytes32 initCodeHash) internal pure returns (address);

Parameters

Name	Type	Description
salt	uint256	The salt to use for the deployment.
initCodeHash	bytes32	The init codehash of the contract to deploy.

Returns

Name	Type	Description
<none>	address	addr The address of the deployed contract.

deployProxyWithCreate2

Deploys a ERC1967 Proxy for the already deployed implementation contract.

function deployProxyWithCreate2(address implementation, uint256 salt) internal returns (address);

Parameters

Name	Type	Description
implementation	address	The implementation contract address.
salt	uint256	The salt that will be used for the deployment of the proxy.

Returns

Name	Type	Description
<none>	address	instance The determinitic address of the deployed proxy contract.

deployProxyWithCreate2IfNecessary

Deploys a ERC1967 Proxy for the already deployed implementation contract if it hasn't been deployed yet.

function deployProxyWithCreate2IfNecessary(address implementation, uint256 salt) internal returns (address);

getCreate2ProxyAddress

Returns the deterministic address of a ERC1967 proxy for the given implementation and salt.

Assumes that the proxy is deployed using deployProxyWithCreate2.

function getCreate2ProxyAddress(address implementation, uint256 salt) internal pure returns (address);

Parameters

Name	Type	Description
implementation	address	The implementation contract address.
salt	uint256	The salt that will be used for the deployment of the proxy.

Returns

Name	Type	Description
<none>	address	instance The address of the deployed proxy contract.
