Pancake-create3-factory

create3-factory to be used by PCS for v4 or future deployments for deterministic address

Context

create1 was rejected as

• its under an EOA (tied to 1 person)

create2 was rejected as

• some of v4 contracts takes WETH as constructor args
• WETH address can differs across chains
• this would result in different address across chains

create3 was selected as

• deterministic address based on just salt
• a tweak on the proxy CustomisedProxyChild.sol allows us to run some methods (transferOwnership)

Deployment

Pre-req: before deployment, the follow env variable needs to be set

// set rpc url
export RPC_URL=https://

// private key need to be prefixed with 0x
export PRIVATE_KEY=0x

// so contract can be verified on explorer
export ETHERSCAN_API_KEY=xx

Create3Factory verification on explorer

In case contract verification fail when running deployment script, run

forge verify-contract <address> Create3Factory --watch --chain <chain_id>
