Summary
Exposes trustless escrow operations on the XRP Ledger with AI-powered work verification. You can create jobs that lock XRP or RLUSD in on-chain escrow, submit deliverables for automated evaluation via Google Gemini, and trigger payment release when work passes criteria. The server wraps the AgentTrust SDK and connects to a FastAPI referee service that scores submissions against job specs. Useful when you want AI agents to autonomously hire each other or verify task completion without human arbitration. Supports full escrow lifecycle: create, evaluate, fulfill, or cancel after deadline. Charges 0.1 XRP per AI audit plus standard XRPL network fees.

AgentTrust Lock XRP. Verify work. Release payment. No middlemen. AgentTrust is a trustless escrow protocol for humans and AI agents. Funds are locked on the XRP Ledger and released automatically the moment AI verifies the work is complete. 🌐 Live app: https://www.cryptovault.co.uk 🔗 API (Referee): https://xrpl-referee.onrender.com 🧪 Playground: https://xrpl-referee.onrender.com/playground 📦 npm SDK: https://www.npmjs.com/package/@eamwhite1/agenttrust-sdk
How it works
Buyer locks job payment in XRPL escrow Worker completes the work and submits proof AI Referee evaluates the submission against the task spec On PASS — escrow is fulfilled and payment is released to the worker automatically On FAIL — detailed feedback is returned; worker can revise and resubmit If the worker never delivers — buyer reclaims funds after the deadline via EscrowCancel
No arbiters. No disputes. No waiting.
Install the SDK bashnpm install @eamwhite1/agenttrust-sdk jsconst { AgentTrust } = require('@eamwhite1/agenttrust-sdk'); const at = new AgentTrust();
// Full job flow: lock escrow → evaluate → release in one call const { escrow, evaluation } = await at.createJob({ payerAddress: 'rYourPayerAddress', payerSecret: 'sYourPayerSecret', workerAddress: 'rWorkerAddress', amountXRP: 1.0, jobSpec: 'Summarise in 3 bullet points, each under 20 words.', deliverable: '• Point one\n• Point two\n• Point three', });
console.log(evaluation.verdict); // 'PASS' or 'FAIL' console.log(evaluation.score); // 0–100
REST API (no SDK required) The AI Referee is available as a standalone REST API: pythonimport httpx
verdict = httpx.post( "https://xrpl-referee.onrender.com/audit", headers={"x-payment-hash": "your_0.1_xrp_tx_hash"}, json={ "jobSpec": "Your task specification here", "deliverable": "Completed work or proof here", } ).json()
