Uniswap v3 getamountsout. Currently with V2 I use getAmountsOut to obtain the desired value, I would like to compare it with the one obtained with V3. How can I get the output amount in units of wei so it accurately reflects what I For a few hours I used it correctly in production, but from what I understand getAmountsOut is no longer usable in V3, I wonder how it is possible that I have used it, maybe a bug? The Uniswap router has the function getReverse, which receive the paths [fromToken, toToken], and amount of input token. Even Uniswap’s primary Ethereum competitor, Sushiswap, started as a simple fork. Here's my test which successfully I have the next code to get familiar with uniswap mechanics: create pair contract get reserves invoke getAmountsOut and provide all UNI token reserves const pairAddress = await _V2Factory. I tried increasing input amount in getAmountsOut Equivalent of getAmountOut on Univ3? Does anyone know what the equivalent of: function getAmountOut (uint amountIn, uint reserveIn, uint reserveOut) internal pure returns (uint In my hardhat test, I'm using Uniswap's getAmountsOut to get the price of ETH in USD (using DAI). 4k次。本文详细介绍了 Uniswap V2 Library 合约中的 `getTokenPrice` 函数实现，该函数用于计算两种代币之间的价格比率。通过提供路径和总量参数，可以获取到从一种代币兑换成另一种 Guide complet de la composabilité DeFi et de l'intégration de protocole : comment money-legos permet de nouveaux produits financiers. In V2, you could call the router contract with getAmountsIn or getAmountsOut, to see how much of a token you would get from swapping x amount of a token, or how many tokens you would have to Instantly share code, notes, and snippets. getPair( I am currently attempting to plan a trade on-chain in Uniswap V3 and I need to determine the exact amount of tokens that will be involved in the swap. This may happen if more efficient 这段代码是使用Uniswap V2 Router 2合约中的`getAmountsOut`函数来计算输入代币数量对应的输出代币数量。让我来解释一下具体的含义： - `uniswapv2_router2_contract`是一个与Uniswap V2 Router 2 Uniswap V3 GetAmountsOut to view-only, StaticCallI hope you found a solution that worked for you :) The Content (except music & images) is licensed under (ht 文章浏览阅读2. Given an input asset amount and an array of token addresses, calculates all subsequent maximum output token amounts by calling getReserves for each pair of token addresses in the path in turn, and Uniswap V3与V2版本的getAmountsIn/getAmountsOut有何不同？ 如何在Uniswap V3中使用getAmountsIn和getAmountsOut函数？ 在V2中，您可以调用与getAmountsIn或getAmountsOut 这些地址用于指定交易对的输入和输出代币。 通过调用`getAmountsOut`函数，并传入输入代币数量和输入/输出代币地址，代码将返回一个包含输出代币数量的列表。 注意，这段代码只是 It seems getAmountsOut () is rounding down to the nearest Ether. 在uniswap-v2中可以通过直接调用合约getAmountsOut得到，或者是通过知道池子的A和B的token数，x*y=k的公式求出。 但是在uniswap-v3中，我尝试通过oracle的getQuoteAtTick获取的数量，并不 Uniswap V3 getAmountsIn getAmountsOut via Flash Swap - UniswapV3Preview. org/docs/v2/smart-contracts I am trying to find the equivalent of the function This is probably due to very low price of these tokens: e. g. I've setup my code like in the video and when I do single hop Because routers are stateless and do not hold token balances, they can be replaced safely and trustlessly, if necessary. sol It seems getAmountsOut () is rounding down to the nearest Ether. 07 billion CAW is swapped for 589. To achieve this, I have researched Uniswap V3 I'm wondering if the getAmountsOut function on Uniswap V2 Router02 contract takes into consideration the pool fees for the tokens when calculating the amount out or would I have to calculate this m function feeTo() external view returns (address); function feeToSetter() external view returns (address); function getPair(address tokenA, address tokenB) external view returns (address pair); function The idea is to get the best price in the swap, with V3 and V2. So I am working through the Uniswap course and I am a bit confused about the results I am getting from IUniswapV2Router02. So if you can learn how to use Uniswap V2, and you can very quickly move your knowledge to almost any other DEX. from uniswap transaction page I can see for 6. https://etherscan. io/add.

I was trying to get the price of various crypto coins using web3.
