TimeLock contract extends from TimelockController from OpenZeppelin Contracts.
contract TimeLock is TimelockController { constructor( uint256 minDelay, address[] memory proposers, address[] memory executors, address admin ) TimelockController(minDelay, proposers, executors, admin) {} } TimelockControllers Openzeppelin has Roles
bytes32 public constant TIMELOCK_ADMIN_ROLE = keccak256("TIMELOCK_ADMIN_ROLE"); bytes32 public constant PROPOSER_ROLE = keccak256("PROPOSER_ROLE"); bytes32 public constant EXECUTOR_ROLE = keccak256("EXECUTOR_ROLE"); I am using hardhat to deploy contracts which deploys TimeLock contract successfully before it runs setupGovernance contract to assign roles but it gives error at timeLock.PROPOSER_ROLE();
Property 'PROPOSER_ROLE' does not exist on type 'BaseContract'
Below is the setupGovernance hardhat script
const setupGovernance: DeployFunction = async function (hre: HardhatRuntimeEnvironment) { const { getNamedAccounts, deployments } = hre; const { log } = deployments; const { deployer } = await getNamedAccounts(); const timeLock = await ethers.getContract("TimeLock", deployer); const governance = await ethers.getContract("GovernorContract", deployer); log("----------------------------------------------------") log("Setting up roles..."); const proposerRole = await timeLock.PROPOSER_ROLE(); const executorRole = await timeLock.EXECUTOR_ROLE(); const adminRole = await timeLock.TIMELOCK_ADMIN_ROLE(); const proposerTx = await timeLock.grantRole(proposerRole, governance.address); await proposerTx.wait(1); // wait for 1 block confirmation const executorTx = await timeLock.grantRole(executorRole, ADDRESS_ZERO); await executorTx.wait(1); // wait for 1 block confirmation const revokeTx = await timeLock.revokeRole(adminRole, deployer); await revokeTx.wait(1); }
