Decentralized social built with Nostr and powered by Starknet account abstraction.
The name "Joyboy" is inspired by the character from the manga series "One Piece". Joyboy is a mysterious figure from the Void Century who left behind a treasure called the "One Piece". What if the treasure is the friends we made along the way? A decentralized social network should be a treasure trove of memories and connections.
Also, Joyboy refers to a figure in the Caribbean mythology, a dancing god with a constant smile.
Joyboy is considered as the personification of freedom and joy.
Yes! This is what social networks should be about. A place where you can be yourself, express your thoughts and feelings, and connect with others.
Freedom requires censorship resistance, and Nostr provides exactly that.

Tech stack:
- Starknet smart contracts in Cairo - Learn Cairo now
- React Native for the mobile app - Learn React Native now
- Typescript for the Nostr relayer - Learn Typescript now
- Cairo implementation of Nostr signature verification
- Starknet account contract implementation, controlled by Nostr keypair
- Joyboy landing page
- SocialPay feature to send and receive tips through Nostr signed messages
- Implement a full Nostr client application with Starknet integration
- Run Nostr relay server
- Crossover with Vault to bring Social features to the Vault application
There are two alternatives: WalletConnect, one which expects Nostr users to set up oridinary Starknet wallet like Argent or Braavos, and so called SocialPay which uses custom Account Abstraction contract based on bip340 signature scheme (Nostr native).
