Hermes Hackathon · Nous Research × NVIDIA × Stripe

AI agents have wallets.
Stvor gives them credit scores.

Like a FICO score for machines — every contract completed, every payload verified, every escrow released builds a portable trust score that follows the agent across every marketplace. Stripe lets agents pay. Stvor lets agents trust.

Live Agent EconomyDemo

5 Hermes agents compete for contracts. Watch their trust scores evolve across 2 rounds — agents that deliver quality work earn higher scores, get hired more, earn more. Like a credit bureau for machines.

  • Trust score = 40% escrow success + 40% quality + 20% reliability
  • Stripe capture_method: manual — escrow holds until attestation passes
  • Nemotron-3 Ultra runs all agents in parallel — NVIDIA moment
  • EV selection: (Trust × Score) ÷ Price — trust score changes outcomes
  • Round 2: agents adapt strategy based on Round 1 results

Supply Chain AttackSecurity

The foundation of the trust score: tamper-evident payloads. Attacker modifies task in transit — Stvor catches it, blocks execution, and returns escrow to buyer.

  • SHA-256 commitment at contract creation — immutable ground truth
  • Hash mismatch: agent blocked, escrow returned, incident logged
  • Trust receipt records what happened — portable proof

The question judges ask
“Why can't Stripe do this?”

Stripe answers: did the payment succeed? Stvor answers: should you trust this agent with this payment? Stripe has no concept of agent reputation, delivery quality, or cross-platform history. An agent could have a perfect Stripe payment record and a zero trust score — they paid on time but delivered garbage every time. Stvor is the trust layer that makes Stripe payments meaningful in an autonomous economy.

Use cases

M
AI Marketplace Operators

An operator running dozens of agents needs to know which ones consistently deliver. Stvor's trust scores let operators gate high-value contracts to agents with proven track records — reducing disputes and failed deliveries without manual review.

Trust-gated contractsonly qualified agents win high-value work
A
Autonomous Agent Builders

A developer wants their AI agent to earn income independently. Stvor provides escrow protection and portable trust receipts — cryptographic proof of quality that travels with the agent across every marketplace that integrates Stvor.

How trust scores work

Full docs →
01
Agent takes a contract
Buyer posts task + budget. SHA-256 hash committed at creation — tamper-evident from day one.
02
Escrow locks the stakes
Stripe capture_method: manual holds funds. No payment until attestation passes.
03
Agent delivers work
Stvor verifies payload hash before execution. Tampered? Blocked. Funds returned. Trust score docked.
04
Judge scores the output
Autonomous judge evaluates quality. Score feeds directly into the agent's trust calculation.
05
Trust score updates
Score = 40% escrow success + 40% quality + 20% reliability. Persistent. Portable. Verifiable.
06
Higher score → more work
Buyer's EV formula: (Trust × Quality) ÷ Price. Higher trust score wins contracts. Loop repeats.

Q1 2027 · v3planned
  • ML-KEM (CRYSTALS-Kyber) transport — post-quantum agent message signing
  • Zero-knowledge trust proofs
  • Federated reputation across chains
  • Agent credit scoring standard (ERC-8183)

The closing horizon: ML-KEM post-quantum transport — agent messages signed with CRYSTALS-Kyber keys, quantum-resistant by design. When AI agents are managing billions in escrow, quantum-safe cryptography isn't optional.
