The Buenos Aires stop of the BNB Chain x YZi Labs Hack Series brought two intense days of building, collaboration, and sharp ideas from across LATAM and the global DevConnect crowd. With 19 submissions, 4 live demos, and a packed venue, the city showed once again why it’s becoming one of the most active blockchain hubs in the region.

Event Overview

Teams kicked off their journey online on November 12 with onboarding and team-formation sessions. By the time they arrived on-site, builders were aligned, prepared, and ready to execute, turning the in-person hackathon into two days of focused, high-quality development.

A big thank-you to our judges for lending their insight and pushing teams to think bigger:

• Jiawei Zhu — IOSG Ventures
• Lorena Zhang — Lista DAO
• Deke Wilkins — Fenbushi Capital
• Keith — SNZ Holding
• Kun Peng — Blockchain Builders Fund; Founder, Stanford Blockchain Accelerator & BASS

Their guidance helped teams refine their design, technical depth, and long-term direction inside the BNB Chain ecosystem.

Before final judging, four teams took the stage for Demo Night. It was an early look at what they were building, paired with direct, actionable feedback from mentors and judges.

The featured teams were:

• ARST Finance
