Hawaii Liquidity Pool is a training project born to give to ganyone who wants to contribute to the project) the possibility to learn Solidity (Defi, Ercs standards ...) & Hardhat. Infact anyone can contribute adding by Defi functionality or improve one that already exists.
Why do you think that https://github.com/Envoy-VC/30-Days-of-Solidity is a good alternative to Hawaii-LiquidityPool
