Open the reportLowDivide Before MultiplyUSDFI Dex & Miner - Audit · CertiK · 12 Sep 2022Fixed
Performing integer division before multiplication truncates the low bits, losing the precision of calculation. ```solidity=73 uint256 bal = checkMining().div(10000).mul(percent[i]); ``` --- ```solidity=81 uint256 bal = checkMining().div(10000).mul(percentPanic[i]); ``` --- ```solidity=90 uint256 receivedWantTokens = IERC20(wantToUSDFI[1]) .balanceOf(address(this)) .div(100000) .mul(mintingFee); ```
Open the reportLowImproper Usage of `public` and `external` TypeUSDFI Dex & Miner - Audit · CertiK · 12 Sep 2022Fixed
`public` functions that are never called by the contract could be declared as `external`. `external` functions are more efficient than `public` functions.
Open the reportLowMissing Zero Address ValidationUSDFI Dex & Miner - Audit · CertiK · 12 Sep 2022Fixed
Addresses should be checked before assignment or external call to make sure they are not zero addresses. ```solidity=122 receiverAddress = _receiverAddress; ``` - `_receiverAddress` is not zero-checked before being used. --- ```solidity=130 receiverMintFeeAddress = _receiverMintFeeAddress; ``` - `_receiverMintFeeAddress` is not zero-checked before being used.

The return value of the transfer()/transferFrom() call is not checked. ```solidity=95 IERC20(wantToUSDFI[1]).transfer(receiverAddress, receivedWantTokens); ``` --- ```solidity=104 IERC20(wantToUSDFI[1]).transfer( receiverMintFeeAddress, receivedWantTokens ); ```
