# Missing IERC20 Interface in `ERC20.sol` contract
Author Revealed upon completion
Missing IERC20 Interface in ERC20.sol contract
Description
The contract does not import nor implement the standard IERC20 interface. It manually defines the ERC20 functions but does NOT declare:
contract ERC20 is IERC20
// SPDX-License-Identifier: MIT
import {ERC20Internals} from "./helpers/ERC20Internals.sol";
import {IERC20Errors} from "./helpers/IERC20Errors.sol";
@> No import here for "IERC20.sol"
@> contract ERC20 is IERC20Errors, ERC20Internals {
Risk
Likelihood:
-
Tools cannot detect that the contract is ERC20-compliant
-
Other contracts expecting a standard interface may fail
-
ABI-level compatibility issues may occur
Impact:
Not formally compliant with ERC20 despite exposing the functions. Integrations may break because systems expect an explicit
IERC20inheritance.
Recommended Mitigation
Add to ensure system works correctly.
