Sentinel Vaults

Sentinel Vaults is a decentralized, on-chain risk management layer built for the era of autonomous AI agents. As AI trading agents become more prevalent, users face a critical problem: handing over full wallet control to an AI is extremely risky. A hallucination or hijacked prompt could instantly drain a user's life savings. Sentinel Vaults solves this by introducing a "trustless middleman" smart contract. Instead of giving the AI direct access to their funds, users deposit funds into a Sentinel Vault on the Monad Testnet and configure immutable on-chain risk rules (e.g., 'Max Swap Size = 2.5 MON', 'Daily Loss Limit = 10 MON'). The AI agent then submits trade intents to the vault via the Para SDK. The smart contract validates the intent against the user's rules. If it complies, the trade executes; if it violates a rule, the vault instantly reverts the transaction, protecting the user's funds. During this hackathon, we learned how to deeply integrate the Para SDK to facilitate seamless cross-chain and AI-to-contract interactions. We also leveraged the extreme low-latency of the Monad Testnet to ensure that our on-chain risk validations do not bottleneck the high-frequency trading capabilities of AI agents.
