Project Story

🛡️ Inspiration

The B2B payments market is plagued by a "trust deadlock." Freelancers fear non-payment, and businesses fear receiving subpar work or being scammed. We built MNEE Sentinel to bridge this gap by creating an autonomous AI treasurer that uses math (ZK-proofs) and smart mandates (EIP-712) to ensure fairness for both parties.


🏗️ What it does

MNEE Sentinel is a cross-platform Treasury Agent (Telegram & Slack) that automates B2B procurement:

  • Autonomous Negotiation: Gemini AI negotiates discounts with vendors directly in the chat.

  • ZK-Verified Escrow: Payments are locked in MNEE and only released once the AI verifies the work matches the mandate.

  • Gasless UX: Users never need to hold ETH; all transactions are sponsored by our custom relayer pattern.

  • Adversarial Governance: A "Red Team" AI auditor (GeminiAuditor) checks every transaction for policy violations before execution.

🚧 Challenges we ran into

  • The "Paranoid" Auditor: Our Red Team AI was so effective it initially blocked high-value demo payments as "potential laundering." We built Smart Escalation Logic so that "limit hits" automatically trigger the Multi-Sig Flow, turning a hard block into a governance opportunity.

  • Docker "Zombie" Processes: Managing dual-bots in one container led to orphan processes. We solved this with concurrently --kill-others to ensure the container self-heals if one bot fails.

  • Audio Codec Mismatch: Slack (.webm) and Telegram (.ogg) send different formats. We implemented dynamic Content-Type detection to ensure Azure Speech reached ~90% accuracy.


🏆 Accomplishments that we're proud of

  • Security-First Architecture: As a Cybersecurity Graduate, this project allowed me apply the principle of Defense-in-Depth (Biometrics → AI Auditor → Multi-Sig) rather than just delivering a functional prototype.

  • Real On-Chain Transactions: Live MNEE transfers on Sepolia with verifiable Etherscan receipts; Generated in the app without having to leave.

  • Multi-Sig Emoji Consensus: High-value transactions require a quorum of "✅" reactions from authorized admins before execution.

  • Adversarial AI Governance: Our internal Red Team AI actively monitors and prevents fraudulent intent in real-time.

  • Voice-to-Intent: Processing biometric voice commands into cryptographically signed mandates via Azure.

  • Enterprise Audit Trail: JSON-LD structured logs that are fully exportable to CSV for corporate compliance.


🚀 What's next for MNEE Sentinel

  • Mainnet Deployment: Moving from Sepolia to Ethereum Mainnet for live MNEE transactions.

  • Advanced ZK-Proofs: Implementing full Groth16 proof generation for private invoice verification.

  • Advanced Multi-Sig: Adding time-locked approvals and threshold-weighted voting for large treasury funds.
