Sentinel DAO is an on-chain treasury firewall powered by Arbitrum Stylus. We prevent treasury hacks by enforcing dynamic risk policies and trust scores at the execution level using Rust logic.
🛡️ The Problem: Static Security is Failing
DAO treasuries lose millions annually because standard multisig wallets (like Gnosis Safe) are static. They verify signatures, not intent. If a signer is phished or their private key is compromised, the multisig approves the transaction because the signature is mathematically valid.
đź’ˇ The Solution: Sentinel DAO
Sentinel DAO acts as an On-Chain Firewall that sits between the treasury and the blockchain execution layer. Even if a hacker possesses a valid private key, Sentinel’s Rust Policy Engine will block the transaction if it violates the DAO’s safety rules.
We introduce "Dynamic Compliance":
1. Trust Scores: Every contributor has a dynamic score based on behavior.
2. Panic Mode: Guardians can instantly freeze assets on-chain when anomalies are detected.
3. Execution Blocking: Malicious transactions are reverted at the protocol level.
🏗️ Why Arbitrum Stylus?
Calculating dynamic risk scores involves complex logic and math that is prohibitively expensive on the standard EVM.
By using Arbitrum Stylus (Rust), Sentinel DAO can:
Compute complex risk models at *10x-100x lower gas costs**.
* Leverage Rust's memory safety guarantees.
* Maintain a hybrid architecture: Solidity for standard interfaces (ERC-20), Rust for heavy computation.
🚀 Key Features
* Hybrid Architecture: Seamless interoperability between Solidity state and Rust logic.
* Guardian Console: Real-time monitoring and manual override capabilities.
* Panic Button: Immediate freeze functionality for compromised accounts.
* Institutional UI: Designed for DAO treasuries and grant programs.

<p>During the hackathon, we built Sentinel DAO from scratch, focusing on the Hybrid Architecture implementation:</p><p>1. Smart Contracts:</p><p>- Developed the Rust Policy Engine (Stylus) to handle risk scoring and whitelist logic.</p><p>- Built the Solidity AccessControl layer to manage roles (Guardian vs. Contributor).</p><p>- Successfully connected Solidity interface to Rust logic via Stylus SDK.</p><p>2. Frontend:</p><p>- Built a Next.js dashboard with "Guardian" and "Contributor" personas.</p><p>- Integrated Wagmi/Viem for seamless interaction with the Stylus contract.</p><p>- Implemented real-time status monitoring (Green/Yellow/Red indicators).</p><p>3. Deployment:</p><p>- Deployed and verified contracts on Arbitrum Sepolia Testnet.</p>
<p>Not Funded</p>
