foundry-create2-deployer

Currently a work in progress - Currently stuck until Foundry implements multiple forks per test, as the script cannot read code deployed in the same transaction (I think)

src/Create2DeployScriptBase.s.sol serves as a basis for Foundry scripts meant to deploy contracts to a deterministic address on any network using CREATE2_DEPLOYER.safeCreate2(salt, code), which has the following interface:

interface ImmutableCreate2Factory {
    function safeCreate2(bytes32 salt , bytes memory contractCreationCode) external;
}

Where salt is a bytes32 with the msg.sender's address encoded as the first 160 bits, and contractCreationCode is the code to be deployed.

Usage

The setUp() method of Create2DeployerBase.s.sol performs the following checks and steps:

1. Check that the KEYLESS_CREATE2_FACTORY is deployed to the network
   • If not, check that KEYLESS_CREATE2_DEPLOYER has sufficient funds to deploy the KEYLESS_CREATE2_FACTORY
     • If not, send funds (0.01 of the native token) to the KEYLESS_CREATE2_DEPLOYER
   • Submit a pre-signed transaction from KEYLESS_CREATE2_DEPLOYER to deploy the KEYLESS_CREATE2_FACTORY
2. Check that the INEFFICIENT_IMMUTABLE_CREATE2_FACTORY is deployed to the network
   • If not, submit a transaction to KEYLESS_CREATE2 to deploy the INEFFICIENT_IMMUTABLE_CREATE2_FACTORY
3. Check that the EFFICIENT_IMMUTABLE_CREATE2_FACTORY is deployed to the network
   • If not, submit a transaction to INEFFICIENT_IMMUTABLE_CREATE2_FACTORY to deploy the EFFICIENT_IMMUTABLE_CREATE2_FACTORY

When overriding the base script, calls to super.setUp() will ensure that the CREATE2_DEPLOYER is available on the network before the body of the script's run() function is executed.
