发布0x报价api

Question

我正在调用报价api，当将其响应传递给ethereum.request()进行事务处理时，MetaMask会弹出非常高的tx费用--1.89BNB！这对这个基本的交换功能来说太高了。

添加这是在bsc网络中，我将从USDT交换到BEP20自定义令牌。

有人能帮帮我吗。

Answer 1

很可能您的交易失败了，Metamask错误地计算了整个气体块的气体。

看看这里的输出，我现在可以看到它正在产生一个错误，https://bsc.api.0x.org/swap/v1/quote?sellToken=0x55d398326f99059ff775485246999027b3197955&buyToken=0xaf3889ba617ac973b358513d9031778d2bc783df&sellAmount=1000000000000000000&slippagePercentage=0.10&takerAddress=0x06125e1457f833E29D5aebAaCdF8eED8A6Febaee

{
    code: 105,
    reason: "IncompleteTransformERC20Error",
    values: {
        outputToken: "0xaf3889ba617ac973b358513d9031778d2bc783df",
        outputTokenAmount: "1373091610763976",
        minOutputTokenAmount: "1398576787535538"
    }
}

此时，0xAPI只适用于标准的ERC20 20/BEP20 20令牌，它不包括在传输时收取费用的令牌(如SHIBIC)。
