v2-core VS revoke.cash

For source code, Uniswap V2 Core and Uniswap V2 Peripheral

Here is the Uniswap V2 on github: https://github.com/Uniswap/v2-core

Eh, Curve pools and other invariant-based AMMs have some interesting properties outside traditional finance, bank runs, etc.

I'd read up on the Uniswap constant product invariant (xy=k) and consider reading the Uniswap v2 code (it's a pleasure to read) [0].

Then check out the StableSwap paper by Curve founder Michael Egorov [1]

Finally if you want a well-documented implementation to read in Solidity, check out Saddle [2]. Disclaimer, I helped write the first iteration.

UniswapV2Pair.sol：https://github.com/Uniswap/v2-core/blob/master/contracts/UniswapV2Pair.sol

Any of those above functions that have require statements could have triggered it. I guess that is why you suggested the "hardhats console log". I am not familiar with that and will get right on trying to get that to work. Sorry for slow response, it seems since your message I have went all up and down the entire uniswap code database that includes the router, pair, libraries, transferhelper, WETH, etc.... So I just had the most extensive crash course I have ever had. hahahaha... Thanks for pointing me in that direction. I have learned A LOT. Though I still haven't figured out why the error is happening so I will now try using the hardhats console log to debug it.

The function comes from UniswapV2Pair.sol, shown here:

FWIW, I'd also revoke this contract spending approval, since you have a significant amount of USDC sitting on your wallet that could be moved by a malicious actor if that smart contract is exploited. I typically use Revoke.cash for this. It's also open source In the future, it's best practice to only approve the amount that you need, though I don't know if that's possible going through ledger live. MetaMask let's you edit the approval amount before you send the transaction, so that's typically what I do.
