Missing zero address check :

https://github.com/code-423n4/2022-05-velodrome/blob/main/contracts/contracts/PairFees.sol#L13-L17 _token0 and _token1 is not checked whether they are 0 addresses

https://github.com/code-423n4/2022-05-velodrome/blob/main/contracts/contracts/Velo.sol#L56-L58 _to can be a 0 address , and the transferred fund, would be forever locked
