Registration deadline: November 10 2025
If you’re a developer, founder, or Web3 innovator looking to launch your next big project — this is one to mark on your calendar. The BNB Chain x YZi Labs Local Hack: Buenos Aires is your chance to gain mentorship, build alongside peers, and potentially tap into meaningful funding pathways. Let’s dive into what the event entails, how you can participate, and how to make the most of the opportunity.
What’s the event about?
The hackathon is part of the first stop in the “Local Hack Series” run by BNB Chain in partnership with YZi Labs. (BNB Chain)
In Buenos Aires, from November 15-16, 2025, participants will convene in person (after an online pre-hack phase) to build Web3 projects in collaboration with mentors, ecosystem partners, and other builders. (BNB Chain)
Registration closes on November 10 — if you’re considering joining, now’s the time to act. (BNB Chain)
Significance
There are several compelling reasons this event is worth your attention:
- Mentorship & network access – Participants aren’t just showing up to code: you’ll have access to BNB Chain’s technical and business-development teams, ecosystem experts, and fellow builders, offering a real chance to refine your idea and execution. (BNB Chain)
- Funding and long-term support – The hackathon is positioned as a gateway to larger support channels: top teams gain access to the $1 billion Builder Fund via BNB Chain’s ecosystem programs. (Blockchain News)
- Focused on innovation & regional impact – Projects can be built in one of eight tracks (Trading, RWA, AI, DeSci, DeFi, Payments, Wallets, or Regional Impact), meaning there’s flexibility to align your idea with something meaningful for Latin America or global Web3. (BNB Chain)
- In-person build environment – For many developers, being side-by-side with mentors, other teams, and real feedback is a game changer. The hackathon offers online pre-hack activities (Nov 12-14) then the live event in Buenos Aires (Nov 15-16). (BNB Chain)
All of this combined makes the event more than just a two-day challenge—it’s a launchpad.
Key Details at a Glance

Who should attend?
This is a valuable opportunity if you’re any of the following:
- A developer or team already working with or interested in building on the BNB Chain ecosystem.
- Someone with an idea for a Web3 product that fits one of the tracks above (especially with regional impact or Latin America in mind).
- A founder or builder seeking mentorship, funding, and ecosystem connections—not just a fun hackathon, but a meaningful step forward.
- Someone comfortable working quickly, deploying code, and demoing a product in a short timeframe (with support).
Less ideal if you are looking for a leisurely project or simply want to attend as a spectator; this is built for builders who are ready to execute.
How to prepare and maximise your chances
Since the registration deadline is approaching and the event is intense, here are practical tips to help you hit the ground running:
Ahead of registration
- Ensure you meet the submission requirements: open-source, deployed/testnet ready, BNB Smart Chain or opBNB integrated.
- Clarify which track you want to build in — picking early helps refine your concept.
- If possible, register your team or be ready to join one. Teams often perform better with diverse skill sets (frontend, backend, Web3 integrations).
- Browse the developer toolkit offered by BNB Chain: documentation, SDKs, bridges, testnet endpoints. (BNB Chain)
- Think about a problem you want to solve (especially one with regional Latin America context) rather than starting from scratch with no direction.
During the pre-hack (Nov 12-14)
- Engage actively in the online sessions: this is your chance to refine the idea, meet potential teammates, get mentorship input.
- Use this time to define your demo vision: what will you be able to show by Nov 16?
- Finalise architecture & stack: choose BNB Smart Chain or opBNB, decide how you’ll deploy, test flows.
- Prepare your assets: GitHub repo, deck, demo video, contract address with at least two transactions (as required). (BNB Chain)
On-site (Nov 15-16)
- Use the physical space to network: meet mentors, other teams, ask questions, get real-time feedback.
- Keep your milestones tight: the demo day is on Nov 16.
- Prepare your pitch: beyond the build, you’ll be presenting. Make sure you can clearly articulate problem, solution, roadmap, and integration within the BNB ecosystem.
- Submit early if possible: there may be system or review delays—committing early reduces risk.
Post-hack
- If you’re one of the standout teams, you’ll have further opportunities: fast-track to the MVB Program via EASY Residency, up to $50,000 ecosystem support, and access to the $1 B Builder Fund. (BNB Chain)
- Even if you don’t win a top prize, consider maintaining momentum: keep building, keep open-sourcing, keep engaging with the BNB ecosystem.
- Leverage the network: the mentors, the other teams, the ecosystem partners. Building relationships can yield long-term value.
What this means for the region & ecosystem
The focus on Buenos Aires — and Latin America more broadly — is significant. By hosting a major hackathon in this region, BNB Chain is signalling its commitment to local builders and regional innovation.
This regional emphasis (via the “Regional Impact” track) means that if you have an idea tailored for Latin America — for example, payments infrastructure, on-chain financial inclusion, wallets with localised UX, decentralised science addressing local challenges — you may have an edge. (BNB Chain)
Moreover, the hackathon is part of a larger global series — following this, other cities like Bangalore, Johor Bahru, Abu Dhabi, Hong Kong will host editions. (BNB Chain)
So participating here isn’t just a one-off event; it could be the start of building in a global ecosystem.
Quick FAQ

Yes, solo hackers are welcome — though forming a team often helps boost viability and scale. (Luma)
Q: Do I need to travel to Buenos Aires or can I build remotely?
The in-person onsite hack is in Buenos Aires (Nov 15-16). There is an online pre-hack phase (Nov 12-14) to get ready. If you cannot attend in-person, your ability to participate may be limited — check registration terms. (BNB Chain)
Q: What are the judging criteria?
Submissions will be judged based on: design & usability, scalability, innovation, open-source nature, and integration (with BNB ecosystem). (BNB Chain)

Prize pool up to US$160,000 in cash + ecosystem support. Top teams may receive cash, up to $50,000 in support packages, fast-track interviews for the MVB program, and potential access to the Builder Fund. (MEXC)
Q: Does the project need to be live on mainnet?
The requirement: project must be “live on the testnet or mainnet after the announcement date” and must be connected to the opBNB/BSC mainnet or testnet in some way. (BNB Chain)
Conclusion
If you’re reading this and you’ve been looking for the right moment to jump into building — this could be it. The combination of mentorship, funding potential, ecosystem access and regional focus makes the BNB Chain x YZi Labs hackathon in Buenos Aires a real opportunity for builders.
Don’t let the registration deadline pass without deciding: forming a team, defining a track, and starting your preparation now increases your chance of success.
If you’d like help brainstorming ideas for one of the tracks (Trading, AI, DeFi, etc.), or want a review of your pitch or demo plan, I’d be happy to help.
