Contract: Smart Contract for X7R fee discounts

This contract will NOT be renounced.

The following are the only functions that can be called on the contract that affect the contract:

    function setEcosystemMaxiNFT(address tokenAddress) external onlyOwner {
        require(address(ecoMaxiNFT) != tokenAddress);
        address oldTokenAddress = address(ecoMaxiNFT);
        ecoMaxiNFT = IERC721(tokenAddress);
        emit EcosystemMaxiNFTSet(oldTokenAddress, tokenAddress);
    }

    function setLiquidityMaxiNFT(address tokenAddress) external onlyOwner {
        require(address(liqMaxiNFT) != tokenAddress);
        address oldTokenAddress = address(liqMaxiNFT);
        liqMaxiNFT = IERC721(tokenAddress);
        emit LiquidityMaxiNFTSet(oldTokenAddress, tokenAddress);
    }

    function setMagisterNFT(address tokenAddress) external onlyOwner {
        require(address(magisterNFT) != tokenAddress);
        address oldTokenAddress = address(magisterNFT);
        magisterNFT = IERC721(tokenAddress);
        emit MagisterNFTSet(oldTokenAddress, tokenAddress);
    }

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