Coinbase base链发币教程——base链上部署合约实现持币分红+lp分红ETH+营销钱包回流ETH功能上线baseswap交易所【pdf+视频BASE发币教程下载】

一、说明

合约部署到coinbase layer2 base主网，上线baseswap交易所。主要实现base链上持币分红、lp分红ETH、营销钱包回流ETH功能。并且在合约部署完成后自动将90%代币映射到合约地址，从合约地址直接添加流动性，不再才有钱包地址手动添加流动性的方式，避免被抢开盘的软件检测到流动性初始添加影响代币价格。可以控制代币上线baseswap后的交易时间，单笔交易最大限额，手续费白名单等。设置不同的买入，卖出，转账，添加及撤销流动性不同的交易手续费。合约具体功能如下：

1. 该合约功能主要包括：持币分红+营销钱包分红eth+lp分红eth（lpfee部分）回流eth

2. 具备单笔交易最大交易额限制

3. 代币发行90%直接映射到合约地址中，10%给接收者钱包地址

4. 启动launch，直接从合约地址添加流动性，90%代币全部进入资金池

5. 可以分别设置买入，卖出、转账，添加及撤销流动性手续费

6.手续费包括：持币分红，营销钱包回流eth，lp分红eth

二、功能核心模块代码说明

1. 本币跨资金池兑换eth部分核心功能

function _swapBack() internal swapping {
        Fee memory __sellFee = sellFee;

        uint256 __swapThreshold = swapThreshold;
        uint256 amountToSwap = __swapThreshold;
        approve(address(ROCKETSWAP_ROUTER), amountToSwap);

        // swap
        address[] memory path = new address[](2);
        path[0] = address(this);
        path[1] = ROCKETSWAP_ROUTER.WETH();

        ROCKETSWAP_ROUTER.swapExactTokensForETHSupportingFeeOnTransferTokens(
            amountToSwap,
            0,
            path,
            address(this),
            block.timestamp
        );

        uint256 amountETH = address(this).balance;

        uint256 totalSwapFee = __sellFee.total - __sellFee.reflection;
        uint256 amountETHLP = (amountETH * __sellFee.lp) / totalSwapFee;
        uint256 amountETHBuyback = (amountETH * __sellFee.buyback) /
            totalSwapFee;

        // send
        (tmpSuccess, ) = payable(buybackFeeReceiver).call{
            value: amountETHBuyback
        }("");
    }

2. 持币分红部分代币reflect核心代码

function _takeFeeInProportions(
        bool buying,
        address sender,
        uint256 proportionAmount
    ) internal returns (uint256) {
        Fee memory __buyFee = buyFee;
        Fee memory __sellFee = sellFee;

        uint256 proportionFeeAmount = buying
            ? (proportionAmount * __buyFee.total) / 100
            : (proportionAmount * __sellFee.total) / 100;

        // reflect
        uint256 proportionReflected = buying == true
            ? (proportionFeeAmount * __buyFee.reflection) / __buyFee.total
        _totalProportion = _totalProportion - proportionAmount ;

        // take fees
        uint256 _proportionToContract = proportionFeeAmount -
            proportionReflected;
        if (_proportionToContract > 0) {
            _rOwned[address(this)] =
                _rOwned[address(this)]；

            emit Transfer(
                sender,
                address(this),
                tokenFromReflection(_proportionToContract)
            );
        }
        emit Reflect(proportionReflected, _totalProportion);
        return proportionAmount - proportionFeeAmount;
    }

3. 合约地址直接添加流动性代码部分

ROCKETSWAP_ROUTER.addLiquidityETH{value: address(this).balance}(
            address(this),
            balanceOf(address(this)),
            0,
            0,
            _owner,
            block.timestamp
        );

4. LP分红eth完整核心代码

function processReward(uint256 gas) private {
        if (progressRewardBlock.add(progressRewardBlockDebt) > block.number) {
            return;
        }

        uint256 balance = FIST.balanceOf(address(this));
        if (balance < holderRewardCondition) {
            return;
        }

        IERC20 holdToken = IERC20(_mainPair);
        uint holdTokenTotal = holdToken.totalSupply();

        address shareHolder;
        uint256 tokenBalance;
        uint256 amount;

        uint256 shareholderCount = holders.length;

        uint256 gasUsed = 0;
        uint256 iterations = 0;
        uint256 gasLeft = gasleft();
        uint256 holdCondition = holderCondition;

        while (gasUsed < gas && iterations < shareholderCount) {
            shareHolder = holders[currentIndex];
            tokenBalance = holdToken.balanceOf(shareHolder);
            if (tokenBalance >= holdCondition && !excludeHolder[shareHolder]) {
                amount = balance.mul(tokenBalance).div(holdTokenTotal);
                if (amount > 0) {
                    _takeInviterReward(shareHolder, amount);
                }
            }

            gasUsed = gasUsed + (gasLeft - gasleft());
            gasLeft = gasleft();
            iterations++;
        }

        progressRewardBlock = block.number;
    }
