Submission Details
Severity:
Valid ERC20s with no `decimals()` implementation are not supported
Vulnerability Details
As per the ERC20 standard, the decimals() function is OPTIONAL.
Thus, some valid ERC20 tokens may not have the decimals() function implemented. Thus reverting on the _create() function here:
uint8 tokenDecimals = IERC20Metadata(address(token)).decimals();
Impact
Expected supported ERC20 tokens, as per the contest docs Scope/Compatibility section and ERC20 specification are not supported.
Recommendations
Add to the list of supported tokens those that have the decimals() function implemented.
