AI agents (OpenClaw, etc.) are about to manage real money autonomously. But there's no trust infrastructure:
- How does Agent A verify Agent B is legitimate before paying it?
- How do you stop a compromised agent from draining funds?
- How do you prove an audit ticket is authentic without trusting the issuer?
- How do you gate payments based on verifiable risk scores?
AgntorShield = 3 onchain modules in a single contract, bridged with off-chain AI security via @agntor/sdk:
Register AI agents with audit levels (Bronze/Silver/Gold/Platinum), operation constraints, reputation scores (basis points), and an emergency kill switch — all onchain and verifiable by any counterparty.
agntorshield register --agent-id trading-bot-001 --level Gold --reputation 85
agntorshield verify-agent --agent-id trading-bot-001 --op-value 5.0
agntorshield kill-switch --agent-id trading-bot-001 --active trueGenerate JWT audit tickets using @agntor/sdk and anchor their keccak256 hashes onchain. Anyone can verify a ticket is authentic, unexpired, and unrevoked — without trusting the issuer.
agntorshield anchor-ticket --agent-id trading-bot-001 --level Gold --ttl 3600
agntorshield verify-ticket --hash 0x...Risk-gated escrow for agent-to-agent payments. The @agntor/sdk settlement guard scores transaction risk — the onchain contract enforces release rules:
| Risk Score | Release Policy |
|---|---|
| < 30% | Payer can release |
| 30-70% | Admin release required |
| > 70% | Funds held, admin only |
agntorshield escrow --payee 0x... --amount 0.5 --service "code review" --reputation 0.85
agntorshield release --escrow-id 0 OFF-CHAIN (@agntor/sdk) ONCHAIN (BNB Chain)

The security analysis happens off-chain (prompt injection detection, secret redaction, SSRF protection, settlement risk scoring). The trust verification and value transfer happens onchain. Neither layer trusts the other — they verify.

Agent Registry (9 tests)
✔ register new agent ✔ reject duplicates ✔ reject empty ID
✔ reject reputation > 10000 ✔ update parameters ✔ toggle kill switch
✔ verify trust ✔ deactivate agent ✔ reject non-owner updates
Ticket Anchoring (5 tests)
✔ anchor ticket ✔ reject duplicates ✔ reject expired
✔ revoke ticket ✔ track agent tickets
Settlement Escrow (8 tests)
✔ create/fund escrow ✔ reject zero-address ✔ reject self-escrow
✔ release low-risk ✔ block payer high-risk ✔ admin release high-risk
✔ dispute + refund ✔ track protocol stats
Admin Functions (3 tests)
✔ transfer admin ✔ reject non-admin ✔ admin update reputation

- Risk thresholds are onchain constants — 30% auto-release, 70% auto-hold. Not configurable by agents. Prevents gaming.
- Kill switch — Agent owners can instantly freeze their agent. For the "oh shit" moment when an agent goes rogue.
- Constraints hash — Full constraint JSON lives off-chain (gas efficient), but keccak256 hash stored onchain. Verifiable by anyone.
- Settlement hash — Off-chain risk analysis from
@agntor/sdkis hashed with each escrow. Immutable audit trail of why funds were held or released.

This project was built with the assistance of AI coding tools (OpenCode / Claude) as encouraged by the hackathon guidelines. AI was used for:
- Smart contract development and optimization
- Test suite generation and edge case coverage
- CLI application development
- Web dashboard creation
- Deployment scripting and gas optimization
All code was reviewed, tested, and verified by the developer before deployment.
