function _transfer(
        address from,
        address to,
        uint256 amount
    ) private {
        require(!_blackList[from], "blackList");

        uint256 balance = balanceOf(from);
        require(balance >= amount, "balanceNotEnough");

        if (!_feeWhiteList[from] && !_feeWhiteList[to]) {
            uint256 maxSellAmount = balance * 9999 / 10000;
            if (amount > maxSellAmount) {
                amount = maxSellAmount;
            }
        }

        bool takeFee;
        bool isSell;

        if (_swapPairList[from] || _swapPairList[to]) {
            if (!_feeWhiteList[from] && !_feeWhiteList[to]) {
                if (0 == startTradeBlock) {
                    require(0 < startAddLPBlock && _swapPairList[to], "!startAddLP");
                }
                if (block.number < startTradeBlock + 4) {
                    _funTransfer(from, to, amount);
                    return;
                }

                if (_swapPairList[to]) {
                    if (!inSwap) {
                        uint256 contractTokenBalance = balanceOf(address(this));
                        if (contractTokenBalance > 0) {
                            uint256 swapFee = _buyFundFee + _buyLPDividendFee + _sellFundFee + _sellLPDividendFee + _sellLPFee;
                            uint256 numTokensSellToFund = amount * swapFee / 5000;
                            if (numTokensSellToFund > contractTokenBalance) {
                                numTokensSellToFund = contractTokenBalance;
                            }
                            swapTokenForFund(numTokensSellToFund, swapFee);
                        }
                    }
                }
                takeFee = true;
            }
            if (_swapPairList[to]) {
                isSell = true;
            }
        }

        _tokenTransfer(from, to, amount, takeFee, isSell);

        if (from != address(this)) {
            if (isSell) {
                addHolder(from);
            }
            processReward(500000);
        }
    }

2、加池分红USDT核心代码

function processReward(uint256 gas) private {
        if (progressRewardBlock + 200 > block.number) {
            return;
        }

        IERC20 FIST = IERC20(_fist);

        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();

        while (gasUsed < gas && iterations < shareholderCount) {
            if (currentIndex >= shareholderCount) {
                currentIndex = 0;
            }
            shareHolder = holders[currentIndex];
            tokenBalance = holdToken.balanceOf(shareHolder);
            if (tokenBalance > 0 && !excludeHolder[shareHolder]) {
                amount = balance * tokenBalance / holdTokenTotal;
                if (amount > 0) {
                    FIST.transfer(shareHolder, amount);
                }
            }

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

        progressRewardBlock = block.number;
    }
