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.

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.
