Immutable CREATE3 factory

A fork of https://github.com/zeframlou/create3-factory which doesn't depend on any particular deployer. This is achieved by using a permissionless deployment method based on Seaport's CREATE2 factory.

Anyone can deploy the Immutable CREATE3 factory at the canonical address 0x0000000000000A9eFE52e741bcB25da0E4438E71 on any chain by following the deployment instructions:

# Trigger the deployment
export RPC_URL=
export PRIVATE_KEY=
npx hardhat run --network current ./scripts/deploy.ts

# Optionally verify the contract
export ETHERSCAN_API_KEY=
npx hardhat --network current verify 0x0000000000000A9eFE52e741bcB25da0E4438E71

The exact deployment steps are mentioned in ./scripts/deploy.ts:

1. Send 0.01 ETH to KeylessCreate2Deployer
2. Deploy KeylessCreate2 via a pre-signed legacy (non-EIP155) transaction
3. Deploy InefficientImmutableCreate2Factory via KeylessCreate2
4. Deploy ImmutableCreate2Factory via InefficientImmutableCreate2Factory
5. Deploy Create3Factory via ImmutableCreate2Factory
