What we built
OPN Guestbook is a lightweight Web3 guestbook built on OPN Chain.
Users can connect their wallet, send messages on-chain, and interact directly with a public smart contract through a simple decentralized interface.
The project combines:
- Solidity smart contracts
- Wallet interaction
- On-chain social interaction
- Community participation
Why
The purpose of this project is to explore decentralized social interaction and builder identity inside the OPN ecosystem.
This project also helps expand knowledge in:
- Smart contract development
- Web3 interaction
- Decentralized application design
- On-chain community engagement
How it works
- Users connect their wallet
- Messages are submitted directly to the smart contract
- Every interaction is stored on-chain
- The contract remains publicly accessible for all users
