B2PIX - A P2P Bitcoin Marketplace on Stacks

This demo showcases B2PIX, a peer-to-peer Bitcoin marketplace built for Brazil using PIX payments. Users can buy and sell Bitcoin non-custodially, with smart contracts coordinating settlement. When a PIX payment is verified, the contract automatically releases BTC, removing the need for escrow agents, custodians, or trusted intermediaries. Key highlights: - P2P Bitcoin trading designed for Brazil - PIX-based fiat payments - Non-custodial BTC settlement - Smart contracts handle release logic - No centralized custody or manual escrow This project was built by Ronoel Junior during the Hacker House and explores how Bitcoin-native smart contracts can power real-world, local payment rails while preserving self-custody. 🔗 Learn more: https://b2pix.org/ #Bitcoin #Stacks #P2P #PIX #noncustodial #bitcoindeFi #hackerhouse #smartcontracts
