require(tradeAmount != 0, "Trade amount must be non-zero");
require(tradeAmountSqrt != 0, "Trade amount sqrt must be non-zero");

}
Incorporating these checks guarantees the validity of parameters, thereby preventing unintended behavior within the protocol.

Vulnerability details
Impact:
Lack of proper validation for parameters can introduce unforeseen behavior and security risks in the protocol.
Proof of Concept:
Consider the following code from RebalancingLibrary.sol:
solidity function rebalance( GlobalDataLibrary.GlobalData storage globalData, uint256 pairId, int256 tradeAmount, int256 tradeAmountSqrt, bytes memory settlementData ) external returns (RebalancingResult memory result) { // Code omitted for brevity }
Parameters such as pairId, tradeAmount, and tradeAmountSqrt does not contain validation checks,which will lead to potential issues during execution.
Tool Used:
Manual Review.
Recommended Mitigation Steps:
validation checks should be Introduce for parameters so as to ensure they are within expected ranges and readily adhere to protocol requirements:
diff function rebalance( GlobalDataLibrary.GlobalData storage globalData, uint256 pairId, int256 tradeAmount, int256 tradeAmountSqrt, bytes memory settlementData ) external returns (RebalancingResult memory result) {
Incorporating these checks guarantees the validity of parameters, thereby preventing unintended behavior within the protocol.
