每天增加TRC20令牌的总供应量

Question

我想在Tron区块链上发布一个令牌，我从以下地址获得了令牌的模板：https://github.com/TRON-Developer-Hub/TRC20-Contract-Template

问题是，我希望将我的令牌设置为每天自动生成指定数量的令牌。(例如，每天最多2000个令牌)

我应该在模板中添加什么？

你可以添加一个函数，如下所示。但是您必须手动执行mintDaily()

    uint256 constant private dailyMinted = 2000e18;
    uint256 lastMintTime;

    address public _owner;
    
    constructor(
        string memory name,
        string memory symbol,
        uint8 decimals,
        address owner
    ) public {
        _name = name;
        _symbol = symbol;
        _decimals = decimals;

        _owner = owner;
        lastMintTime = block.timestamp;
    }
    
    function mintDaily() public {
        require(_owner == msg.sender, "not permitted");
        // 24h = 86400
        require(lastMintTime + 86400 >= block.timestamp, "mint already" );
        _mint(msg.sender, dailyMinted);
        lastMintTime = block.timestamp;
    }
