Uniswap Deep Dive 1:
For source code, Uniswap V2 Core and Uniswap V2 Peripheral

Can I directly swap ETH with an ERC-20 token on DEX like Uniswap?
u/lapurita is right. Uniswap has periphery contracts which are created solely to make the end user experience easier. They have a function to swap ETH for tokens, but the first step is to convert ETH to WETH and then make the swap. Take a look at the Uniswap (v2) source code to see for yourself: https://github.com/Uniswap/v2-periphery/blob/master/contracts/UniswapV2Router02.sol

Error When Deploying Token Contract to TestNet?
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.

Transaction has Input but no Output. Can someone help me understand why this transaction is failing on the function call?
I've never implemented a flash swap, but I don't see where you exchange anything before your callback to resolve the initial amount. Have you seen Uniswap's full example?

[ETH-Brownie] How can I import from github when the version number includes letters and numbers?
However, I am having trouble importing the Uniswap/v2-periphery because the only tag is 1.0.0-beta.0 shown here. I've tried importing in the following ways with no success:
-
How can you execute a function if a contract on has external functions?
Learning about flash swaps on uniswap and I'm reading thru this example code and i noticed that this contract only has external functions.
