Summary

Vulnerability Detail

The previous contest issue Protocol fee from Market.sol is locked
https://github.com/sherlock-audit/2023-07-perennial-judging/issues/52 seems still exist in this contest codebase.

    function _claimFee(address receiver, UFixed6 fee) private returns (bool) {
        if (msg.sender != receiver) return false;

        token.push(receiver, UFixed18Lib.from(fee));
        emit FeeClaimed(receiver, fee);
        return true;
    }

Nothing changes in function _claimfee and the issue still exist
