Submission Details
Severity:
Use abi.encodePacked to save gas
Summary
abi.encodePacked() consumes less gas than abi.encode().
Vulnerability Details
Impact
Changing abi.encode() function to abi.encodePacked() can save gas since the abi.encode() function pads extra null bytes at the end of the call data. getPoolId() is a pure function but is called internally so it consumes gas when called from other functions inside of the contract.
Tools Used
Manual Analysis
Recommendations
Use abi.encodePacked() instead of abi.encode() to save on gas.
