The Sui Overflow 2026 global hackathon focuses on pushing the boundaries of the Sui ecosystem through practical, production-ready applications. Participants can choose between core tracks such as The Agentic Web and DeFi & Payments, or build on specialized network primitives. Verified prize distributions for the core tracks allocate $30,000 to first place, $15,000 to second, $10,000 to third, and $7,500 to fourth place.
In addition to the main categories, builders leveraging specific ecosystem tools can tap into dedicated sponsor pools, including a $70,000 track for Walrus data integrations and another $70,000 allocated for DeepBook liquidity projects.
