Unchecked return value for IWETH.transfer call
In `EthUniswapPCVController`, there is a call to `IWETH.transfer` that does not check the return value:\\n```\\nweth.transfer(address(pair), amount);\\n```\\n\\nIt is usually good to add a require-statement that checks the return value or to use something like safeTransfer; unless one is sure the given token reverts in case of a failure.
Consider adding a require-statement or using `safeTransfer`.
```\\nweth.transfer(address(pair), amount);\\n```\\n
