Oh, it's easy. Suhail Kakar made a great thread on Twitter about free educational Web3 projects.

1. Pointer
2. Learn Web3 DAO
3. Buildspace
4. Solidity by Example
5. The Road to Web3
6. Odyssey
7. Questbook
8. Smart Contract Best Practices
9. Crypto Zombies
10. Third Academy

By the way, we are aiming to bring those educational projects to Peeranha to help them attract more users, and make Web3 accessible together.
