First Flight #3: Thunder Loan

Summary: Unrequired casting IERC20 variable, as it is already IERC20

Vulnerability Details: No vulnerability, just makes the code more difficult/incongruent to read.

Impact: None

Tools Used

Recommendations:

In function

function repay(IERC20 token, uint256 amount), line 223 is:

AssetToken assetToken = s_tokenToAssetToken[IERC20(token)];

should be replaced with:

AssetToken assetToken = s_tokenToAssetToken[token];

as the 'token' variable is already IERC20.
