Missing checks for `address(0)` #93

Missing checks for address(0)

Low/Info issue submitted by NoOne

Summary

The constructor in the contract initializes key parameters such as token pools and price feeds. However, it lacks checks to ensure that the addresses for _token0Pool and _token1Pool are not zero. This omission can lead to potential issues if these addresses are inadvertently set to zero during deployment, causing the contract to behave unexpectedly or fail.

Vulnerability Detail

The constructor initializes the contract state variables but does not check if the_token0Pool and _token1Pooladdresses are zero. If either of these addresses is zero, it can lead to unexpected behavior or contract failure.

Impact

Contract Misbehavior: The contract may not function as intended if _token0Pool or _token1Pool is zero.

Recommendation

Add checks to ensure that _token0Pool and _token1Pool are not zero addresses during contract deployment. This can be achieved by using require statements in the constructor.
