Announcing the Sui Overflow 2026 Hackathon Winners
Sui Overflow 2026 concluded with 26 winning projects across four tracks, emphasizing infrastructure for AI agents and secure autonomous transactions, alongside innovations in payments and decentralized storage.
Sui Overflow 2026 concluded with 747 submissions from 58 countries, awarding 26 teams across four tracks: Agentic Web, DeFi & Payments, Walrus, and DeepBook. Winners focused on enabling software-driven transactions rather than user interfaces, such as AI agents managing funds within predefined limits without holding private keys. Projects like @Sup_Wallet and Sprout demonstrated how autonomous systems can execute trades and payments securely while maintaining user control.
The DeFi & Payments track highlighted solutions for seamless merchant adoption and cross-border settlements. Quay enables web2 merchants to accept crypto payments without technical integration, while Talise offers gasless dollar accounts with instant on-chain settlement. Brisk introduced a decentralized tap-to-pay system using USDC, and Splash provided an end-to-end B2B payment network with stablecoin settlement and audit trails.
The Walrus track emphasized verifiable ownership and agent behavior in decentralized storage. Kraterion offered S3-compatible storage with tamper-evident agent runs, while Deploy automated website deployment to the decentralized web with on-chain anchoring. Carry introduced proof-carrying memory for AI agents, and Praxis served as security middleware to validate agent transactions before execution.
The DeepBook track focused on prediction markets and trading interfaces. Yosuku provided a consumer-facing layer for DeepBook Predict, Skew rendered 3D volatility surfaces for instant betting, and Flicky gamified prediction markets. Additionally, 10 student teams were recognized for projects including an AI agent identity layer with verifiable credentials stored on Walrus.
