🤓Avoid using "transfer" to send ERC20s

Avoid using "transfer" on your smart contract, instead use "call".

⛔ WRONG

function withdraw(uint256 amount) external {
        msg.sender.transfer(amount);
}

✅RIGHT

function withdraw(uint256 amount) external {
  (bool success, ) = msg.sender.call.value(amount)(""); // HERE's the "CALL"
  require(success, "Transfer failed."); // Confirm the transaction
}

Logic behind execution.
