Most agent demos show money moving. The useful part is the refusal. Tranche for @openservai #SERVHackathon (Kite): evidence -> SERV -> @reppo -> policy gate -> @GoKiteAI Passport. 👉 https://t.co/KsKPrKl9LS Source: https://t.co/N0dzk4jzP8

Steward: an AI agent for RWA vaults that has to earn its limits. The model only proposes. A contract decides. Limits rise only through a verifiable on-chain record. Live demo: https://t.co/Ty6IuqRU9B Code: https://t.co/l0WVeHjATd @openservai #SERVHackathon A thread 🧵👇

Started building SpendGuard for the @openservai #SERVHackathon AI agents got wallet access but no accountability. Prompt-injection drains, "bill-swap" payload swaps, unbounded autonomy. There's no record of what a funded agent *considered, did, declined, and why*. SpendGuard a pre-execution guardrail + immutable audit ledger that makes an agent "board-approved" before it touches money: - schema-forced execution (payload must match the permitted shape or reject) - per-agent spend caps · velocity · human-in-the-loop · emergency freeze - SERV shadow-verify a 2nd agent re-checks the approved binding for injection/drift before signing - x402 bill-swap binder (freezes the signed payload to the exact approved amount + payee + chain + token) - append-only SHA-256 audit chain of considered/did/declined + why, explorer-linkable receipts Counterfactual (replayable live): a $5 approve → attacker swaps to $5,900 → refused. An injection drain → refused, logged. And it's real, not a mock: on an allow it signs + broadcasts to Base Sepolia verified on-chain 0x39805e56…82fb3 (block 47282295). On a deny, nothing hits the chain · Live: https://t.co/LvwcaFtATO · Repo: https://t.co/qr7tah9AWc #SERVHackathon #agents #safety #openserv
