Submission Details
Severity:
Extract common verification into a modifier
Summary
It's convenient to not duplicate code and extract whenever possible such code into a function.
Vulnerability Details
The following code is used multiple times in Lender.sol:
if (pools[poolId].lender != msg.sender) revert Unauthorized();
In such cases, it is recommended to create a modifier that will be verifying that the msg.sender is allowed to use functions addToPool, removeFromPool, updateMaxLoanRatio and updateInterestRate.
It will also save gas by having less code implemented.
