🚩 Challenge 3: Minimum Viable Exchange

This challenge will help you build/understand a simple decentralized exchange, with one token-pair (ERC20 BALLOONS ($BAL) and ETH). This repo is an updated version of the original tutorial and challenge repos before it. Please read the intro for a background on what we are building first!

❗️ NOTE: functions outlined within the DEXTemplate.sol are what works with the front end of this branch/repo. Also return variable names may need to be specified exactly as outlined within the Solutions/DEX.sol file. If you are confused, see solutions folder in this repo and/or cross reference with front-end code.

There is also a Youtube video that may help you understand the concepts covered within this challenge too:
