Hello lovely people
am still in solidity learning curve, and i need your help please

am trying to import this contract to my token smart contract

compound-finance/compound-protocol/blob/master/contracts/Timelock.sol

pragma solidity ^0.5.16;

import "./SafeMath.sol";

contract Timelock {
    using SafeMath for uint;

    event NewAdmin(address indexed newAdmin);
    event NewPendingAdmin(address indexed newPendingAdmin);
    event NewDelay(uint indexed newDelay);
    event CancelTransaction(bytes32 indexed txHash, address indexed target, uint value, string signature,  bytes data, uint eta);
    event ExecuteTransaction(bytes32 indexed txHash, address indexed target, uint value, string signature,  bytes data, uint eta);
    event QueueTransaction(bytes32 indexed txHash, address indexed target, uint value, string signature, bytes data, uint eta);

    uint public constant GRACE_PERIOD = 14 days;
    uint public constant MINIMUM_DELAY = 2 days;
    uint public constant MAXIMUM_DELAY = 30 days;

    address public admin;
    address public pendingAdmin;

This file has been truncated. show original

I have imported the contract by : import { Timelock } from "./Timelock.sol";

and then called it in my contract declaration by
contract XXX is Context, IERC20, Timelock {

am lost here how to write the function inside my contract that will call the timelock contract

the time lock should be called when i want to lock someone from selling their tokens for a specific

my contract is standard ERC20 token

thanks

The Timelock contract is typically not inherited by an ERC20 contract. Usually its deployed by itself and then used in conjunction with a multisig contract or a DOA. The OpenZeppelin Governor example shows how to use it pretty well.

So, you would:

Deploy the Timelock contract by itself.
Deploy your multisig/DOA/Governor contract
Make the multisig/DOA/Governor have both the proposer role and executor role in the Timelock.
Have the account that deployed the contract renounce its TIMELOCK_ADMIN_ROLE role in the Timelock.
Multisig/Doa/Governor queues tasks and then executes tasks from the Timelock.

Technically, you certainly could use the timelock as a parent class of your ERC20, that's just not a common pattern I've seen before.
