【问题标题】:Uniswap v3 nonfungiblePositionManager.mint revert after createAndInitializePoolIfNecessaryUniswap v3 nonfungiblePositionManager.mint 在 createAndInitializePoolIfNecessary 后恢复
【发布时间】:2022-08-29 06:38:03
【问题描述】:
我使用官方部署工具“成功”将 Uniswap v3 部署到 EVM 可比测试网。在NonfungiblePositionManager.createAndInitializePoolIfNecessary() 之后,我打电话给NonfungiblePositionManager.mint() 来创建一个新位置,但它总是会恢复。这是我使用的输入:
console.log("creating pool...");
await NFPositionManagerInstance.createAndInitializePoolIfNecessary(
DaiTokenInstance.address,
USDTTokenInstance.address,
3000,
"80000000000000000000000000000"
); // this can be successfully triggered
console.log("minting a position...")
let tx = await NFPositionManagerInstance.mint({
token0: DaiTokenInstance.address,
token1: USDTTokenInstance.address,
fee: 3000,
tickLower: 193,
tickUpper: 194,
amount0Desired: 1000,
amount1Desired: 1000,
amount0Min: 0,
amount1Min: 0,
recipient: "0x668417616f1502D13EA1f9528F83072A133e8E01",
deadline: Math.round(+new Date()/1000 + 20)
}); // this always revert
有谁知道发生了什么?我计划接下来在合同中对此进行深入调试。

【解决方案2】:
我遇到了同样的问题。有几件事可能是问题所在,但我会先看看我正在工作的代码https://github.com/zack53/uniswapv3-pool-deploy/blob/main/src/test/TERC20.js。我遇到的问题专门与 tickLower 和 tickUpper 相关,因为无故恢复错误。我基本上必须从已部署对的 slot0 获取当前刻度,然后,我还从已部署对中获取了刻度间距。一旦我有了这些,我就用它们来计算允许我建立一个位置的刻度间距。部署的对是我自己部署的一对。两个标记都是 18 位小数。我的代码的 sn-p 如下所示:
// Get tick and tick spacing
let slot0 = await deployedPairContract.methods.slot0().call()
let tickSpacing = parseInt(await deployedPairContract.methods.tickSpacing().call())
// Get correct token order for deployed contract pair
let token0 = await deployedPairContract.methods.token0().call()
let token1 = await deployedPairContract.methods.token1().call()
// Params needed for mint
let params = {
token0: token0,
token1: token1,
fee: pairFee,
tickLower: parseInt(slot0.tick) - tickSpacing * 2,
tickUpper: parseInt(slot0.tick) + tickSpacing * 2,
amount0Desired: 10,
amount1Desired: 10,
amount0Min: 0,
amount1Min: 0,
recipient: accounts[0],
deadline: 5000000000
}
await t1ERC20Contract.approve(UniSwapV3NPositionManagerAddress, BigNumber(1000).shiftedBy(decimals).toFixed(0), { from: accounts[0] })
await t2ERC20Contract.approve(UniSwapV3NPositionManagerAddress, BigNumber(1000).shiftedBy(decimals).toFixed(0), { from: accounts[0] })
await uniswapV3NPositionManager.methods.mint(params).send({ from: accounts[0] })
