Congrats to all the winners of the Sui Overflow hackathon! Incredible work across the board. The winners of this year's Walrus track focused on rethinking how agentic systems (including memory) are built, and each won their share of the $70k prize pool: 🥇 – Kraterion: S3-compatible object storage where users retain full ownership, featuring an integrated AI runtime for tamper-evident agent runs. 🥈 – Deploy by Suize: A deployment tool that pushes websites to the decentralized web in a single call, hosting files on Walrus and verifying hashes on-chain. 🥉– Carry: A memory system for AI agents that forces permission checks and cryptographic proof before an agent can read stored context. 4th place – Praxis: Security middleware that dry-runs every agent transaction, risk-scores the spend, and logs decision receipts directly to Walrus.

The results are in for Walrus Session 4: Walrus Memory World Cup! Builders shipped prediction apps, tournament trackers, and match companions on Walrus. Here are the winners 🧵

🚨 Walrus is a Headline Partner at Sui Overflow 2026, sponsoring our own Walrus Track. Sui Overflow is Sui's global hackathon with three tracks: Walrus, Finance, Infrastructure. The Walrus Track has a $70K prize pool. 🥇 1st: $35,000 🥈 2nd: $15,000 🥉 3rd: $7,500 ⚡️ 4th: $5,000 Agents are moving beyond demos, but the infrastructure isn't ready. They forget context, rely on fragile memory setups, and can't share or verify data across workflows. That's what we want builders to tackle: • Persistent memory • Shared context across agents • Verifiable data and provenance Build real agent systems, not just demos. Registration is open 👇
