Thank you for the video. But why the result I got is a little different from the number I see in the uniswap pool?
Nice video!, i have a question, im making a trading bot, and when try to get prices this smart contract returns always the same number, i mean, i made a loop that calls estamateAmount every 1 min but returns same value, coud this happen? Or there are some issue that i dont know it
How can I add the new Uniswap v3 in your my smart contracts for flashbots simple arbitrage ?thanks(newby asking)
Does anyone know how to communicate with a (eth/other token) liquidity pool? Ethereum doesn't have a token address that I am aware of, but I know they have the liquidity pools.
thankyou everything
Thanks for your Videos, they are really helpfull, is there by change any recomendation on a block chain course that you know? it will be helpfull! thanks againg.
Excellent! Thank you!
After all, the written function shows the average value of the price for secondsAgo, and not the exact value of getAmountOut(in termins uni v2)? And what happens if the amount of amoumtIn swings the price to another tick?
hope to see more vyper series soon!
can you go over how uniswap v3 stores historic TWAPs?
Thanks alot for the tutorial! One question , while testing, in test file ,'twap.test.js' , const DECIMALS_0 = 6n , what does 'n' means here?Is it related to 'chai library?
Thank you so much for this channel!
I was wondering what to use to take the token price in Smart contrat for free, I chose Chailink, but now I will change it, because I need more tokens ERC20 and your solution give me this. But what id cheaper in gas fee 🤔
