# Missing IERC20 Interface in `ERC20.sol` contract
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.
