It was built with FreeCodeCamp.Is this a smart contract library or a full course?It is a course repo: a linked video walkthrough paired with lesson-by-lesson code (Remix, Hardhat, HTML/JS, NextJS projects), not a reusable library.

Beginners with little to no blockchain background who want to go from zero to writing, testing, and deploying Solidity smart contracts and full-stack Web3 frontends.Is the code from this course safe to deploy to mainnet?No — the repo explicitly warns that all course code is for demo purposes only, has not been audited, and should not be considered production ready.
