【中文标题】Pancakeswap liqidty 不适用于分叉令牌【英文标题】:Pancakeswap liqidty not working with forked token 【发布时间】:2021-10-07 11:53:09 【问题描述】:

我已经分叉了新芽代币,并且我已经更改了基本内容,但我不确定池中的流动性是否有效,请建议我如何确保流动性有效,或者是否有任何方法可以发送到pancakeswap 流动资金池到另一个钱包?

【问题讨论】:

【参考方案1】:

合约的代币余额和其他验证决定是否应运行 swapAndLiquify。

bool overMinTokenBalance = contractTokenBalance >= numTokensSellToAddToLiquidity;
if (
    overMinTokenBalance &&
    !inSwapAndLiquify &&
    from != uniswapV2Pair &&
    swapAndLiquifyEnabled
) 
    contractTokenBalance = numTokensSellToAddToLiquidity;
    swapAndLiquify(contractTokenBalance);

如果代币余额大于numTokensSellToAddToLiquidity,并且开启了swap和liquify,并且没有在swap和liquify过程中,并且不是从pair转移,则执行swapAndLiquify。

对此进行测试的唯一方法是部署到测试网,为numTokensSellToAddToLiquidity 设置一个非常低的值并开始进行交易(购买、出售、转移)。你会注意到的第一件事是代币合约将开始持有代币,在到达numTokensSellToAddToLiquidity 之后,你会突然看到大量的交易记录(掉期、液化、代币转移等)。此过程通常由卖出或转让触发。购买不会触发它,因为购买交易来自配对地址。

关于发送到其他钱包而不是 PCS LP,是的,有可能,你可以为所欲为。

【参考方案2】:

我们不能在测试网上这样做。我真的不知道为什么。当overMin Token Balance返回true时,pancakeswap上的交易无法进行,添加LP也不起作用。
