【问题描述】：



  const quotedAmountOut = await quoterContract.callStatic.quoteExactInputSingle(
    immutables.token0,
    immutables.token1,
    immutables.fee,
    amountIn,
    0
  )

我创建了两个 erc20 虚拟令牌并使用 uniswapV3Factory createPool() 方法为它们创建了一个池并获得了池地址。但是当我想使用上面的脚本获取我使用过的代币的现货价格时，它会抛出以下错误：

【解决方案1】：

我发现这里的问题是你提供的代币地址，比如 token0 是 WETH9 你必须提供准确的 WETH9 代币地址，你可以在 etherscan.io 上找到它
