Are you ready to create the next big thing in Web3?

Whether you’re a local developer or flying in for DevConnect Buenos Aires, this is your chance to build, connect, and win with the BNB Chain community.

This edition of BNB Hack: Buenos Aires introduces a series of activities to assist builders ahead of the hackathon, giving you time to meet collaborators, solve your questions with the team, and arrive on-site in Buenos Aires ready to build your project during the in-person hackathon.

Registration closes on November 10, 2025.

Kickoff begins on November 12 with online sessions for orientation and team formation, followed by the offline hackathon in Buenos Aires on November 15–16.

Accepted participants will receive an onboarding email with next steps, including access to Discord and the full pre-hackathon schedule.

Live Demos & Finals

On November 16, the top teams will present their projects live to judges and the BNB Chain community.

Participation in the demo is mandatory for finalists — so bring your best pitch and show us your build!

This hackathon is all about creative freedom. We’re not giving you a prescriptive brief — instead, we’re inviting you to choose a track and build anything you believe pushes the frontier forward.

Select one of the 8 high-level innovation areas below as your foundation, then dream, design, and develop your own idea within it:

• Trading – Next-gen exchanges, liquidity tools, quant systems
• RWA – Tokenized finance, stablecoins, yield protocols
• AI – Smart agents, adaptive contracts, intelligent infrastructure
• DeSci – Open research, transparent collaboration
• DeFi – Lending, composable liquidity, yield aggregation
• Payments – Stablecoin & on-chain settlement
• Wallets – UX innovation, account abstraction, next-gen security
• Regional Impact Track – Projects that reflect LATAM priorities, regional opportunities, or unique local trends are especially encouraged.
