Uniswap docs say: These functions are not gas efficient and should not be called on chain. so, for tokenX, L = 1x10¹⁸ Uniswap and other constant product automated market makers (AMM) use the following invariant for each pool: Where x and y are the amounts of the tokens in the pool and k is a constant. call() from which I'm getting: Get a quote (ie amount out for a given amount in) of an Uniswap V3 pool, by simulating the actual swap, in a Solidity-based test. py - implementation of the equations and examples from the "Liquidity Math in Uniswap v3" paper; subgraph-liquidity-query-example. getAmountsOut() doesn't seem to work with v3, I've searched the web, can't find anything related to v3, I find the best solution to simulate the output of value in uniswap v3, using tick in the structure of uniswap v3 caused a different value between my calculation and realvalue, which is cross ticks swaps. Should I put black garbage bags on the Lets say I have two different routers - Uniswap V2 and Sushiswap To calculate possible arbitrage I use getAmountOut from both routers, so: const amountIn = 1000000000000000000 // 1 ETH const boughtAmount = await uniswapRouter. Previous versions were open-source. While most have talked about the impact V3 can potentially bring on the When calling the router contract to issue a swapExactEthForTokens swap, due to the fluctuation of the market, the router takes a parameter called AmountOutMin which is how much token you want at least from this transaction , so you could still get more tokens than the AmountOutMin tokens initially set , its just you cant receive less tokens than the To get a time weighted average tick or liquidity-in-range, you must call this with two values, one representing the beginning of the period and another for the end of the period. Buying ETH will remove some amount of it from the pool When you use Uniswap v3 adding liquidiy feature (app link), after you select token pair, price range (lower and upper), plus the amount of the 1st token, then the amount of 2nd token is Uniswap V3 GetAmountsOut to view-only, StaticCall.
