[@alexmorison4060]

Your videos come out too rarely… But I hope that the next one will be about CosmicSwap and $Cosmic. I'm so in love with them and I'll be glad to hear your prediction!

[@guanyuwu3657]

I cannot understand why the reserve ratio after swap should be equal to the ratio of token that we have(i.e. (a-s)/b). I even cannot understand the meaning of (a-s)/b. Could you please make them clear?☺

@@smartcontractprogrammer thanks. if you can please answer. Is REMIX enough for all this? If we need another software? thanks agein

When add liquidity goes to contract owner() isn't this a scam?

[@smartcontractprogrammer]

Keeping the examples simple. Shares should be transferred back to the caller with `transferFrom`

Author, i didnt understand why you deleted my comment, where i said that K is changing with every swap. I made an experement, where i check that. This experement is: 1.fork the mainnet 2.write the test, where instatiating UniswapV2Router02 and UniswapV2Pair contracts. 3.call function getReserves() and swapExactETHForTokens() (or swapExactTokensForTokens() (it is not nessasary)) 4.look the reserves before and after swap.

[@smartcontractprogrammer]

I didn't delete your comment. Maybe something wrong with KZbin

[@Ortons171]

@@smartcontractprogrammer Ok, let it be

[@smartcontractprogrammer]

I guess K is not exactly same after swap, when trading fees are included?

[@Ortons171]

@@smartcontractprogrammer yes, it is right. But i don`t catch formulas where it is calculated. If i use your formulas, it will be deffirence between expected and actual.

[@никитамазепа-д7г]

Mm, I can't agree with some of your points. What do you think about @musashifinance, btw? It's a DEFI platform with a taste of Japanese heritage and lots of profitable solutions!

[@oleh1]

You can just avoid using uniswap router and add liquidity in any proportion, avoiding the swap. You still need some B tokens, but it can be a very small amount of them. tokenA.transfer(pair, amountA) tokenB.transfer(pair, amountB) IUniswapV2Pair(pair).mint(msg.sender)

[@Lopol2010]

but isn't that make you instantly have impermanent loss?

[@oleh1]

@@Lopol2010 yes, it will. Swapping tokens and then adding liquidity also exposes you to instant impermanent loss. But adding liquidity directly to a pair avoids complex calculations and consumes less gas

[@Lopol2010]

@@oleh1 very interesting, thanks, sounds like these 2 approaches are equivalent, but I will try test them manually as my math skill too low for formal verification

[@oleh1]

@@Lopol2010 I am not sure that they are equivalent. I did not verify that. But judging by UniswapV2Pair code, they should be equivalent
