সোর্স ↗

Problem / Context

A decentralized application spanning web and mobile: exchange contact details, swap tokens, and trade NFTs without a central operator. The platform had to support wallet-based identity, on-chain asset ownership and real-time messaging across clients.

What it does

Wallet-based contact sharing between users, with Privy wallet authentication
Token swapping across supported chains
A decentralized NFT marketplace with minting and trading via Metaplex
Real-time chat and media sharing over Socket.IO channels
XMTP-based decentralized messaging
Stripe and Firebase integrations for payments and notifications

Engineering notes

React/Next.js web client and a Flutter/React Native mobile client over Node.js/Express services with Socket.IO channels, Solana/Ethereum program interaction through Metaplex, Privy wallet auth, XMTP messaging, MongoDB storage, Redis caching, and Stripe/Firebase integrations. REST + WebSocket hybrid, with Redis for session/cache and Mongo for document state.

Outcome / Value

A full-stack Web3 product spanning web and mobile — a strong showcase of wallet auth, on-chain marketplace flows and real-time messaging for Web3 clients.
