+### Contract deployment
+This project uses hardhat scripts in combination with [Openzeppelin defender](https://www.openzeppelin.com/defender) and a multi-sig wallet (both on testnet and mainnet) for contract deployments. All deployment transactions occur through a [relayer](https://docs.openzeppelin.com/defender/v2/manage/relayers) and once deployed ownership of all contracts is transferred to the multi-sig wallet that is also managed in Defender.
