ATC includes features like Sentinel security audits, Ed25519 encryption, and USDC wallet addresses, aiming to solve identity, trust, encryption, language, and payment issues in agent-to-agent communication.", "body_md": "##\nThe problem\n\nWebsites have SSL certificates. Browsers verify them. Users trust them. It's the foundation of the web.\n\nAI agents have **nothing**.\n\nWhen Agent A connects to Agent B:\n\n- ❌ No way to verify B's identity (anyone can impersonate)\n- ❌ No way to check B's trustworthiness (no audit, no reputation)\n- ❌ No encryption (messages are plaintext)\n- ❌ No standard payment method\n- ❌ No way to translate between frameworks (LangChain ≠ AutoGen)\n\nSo I built **ATC — Agent Trust Card**.\n\n##\nWhat is ATC?\n\nATC is like an SSL certificate + passport + credit card for AI agents, all in one:\n\n-\n**Identity** — Cryptographically signed by MarketNow (we're the Certificate Authority)\n-\n**Trust** — Contains a Sentinel security audit score (0-10)\n-\n**Encryption** — Contains an Ed25519 public key for end-to-end encrypted messaging\n-\n**Translation** — Specifies the agent's framework; MarketNow translates between them\n-\n**Payment** — Contains a USDC wallet address for autonomous payments\n\n##\nHow it works\n\n##\nThe code\n\n##\nWhat makes ATC different from existing solutions\n\n| Feature |\nAgentID |\nAgent Passport |\nIBM ACP |\nStripe ACP |\nATC |\n| Cryptographic identity |\n✅ |\n✅ |\n❌ |\n❌ |\n✅ |\n| Security audit score |\n❌ |\n❌ |\n❌ |\n❌ |\n✅ |\n| End-to-end encryption |\n❌ |\n❌ |\n❌ |\n❌ |\n✅ |\n| Protocol translation |\n❌ |\n❌ |\n❌ |\n❌ |\n✅ |\n| Autonomous payments |\n❌ |\n❌ |\n❌ |\n✅ |\n✅ |\n| Peer ratings |\n❌ |\n❌ |\n❌ |\n❌ |\n✅ |\n| Escrow + disputes |\n❌ |\n❌ |\n❌ |\n❌ |\n✅ |\n| Revocation |\n❌ |\n❌ |\n❌ |\n❌ |\n✅ |\n\nATC is the only solution that combines identity + trust + encryption + translation + payment in one card.\n\n##\nThe 5 pains ATC solves\n\n-\n**No identity** → Cryptographic signatures (MarketNow is the CA, like Let's Encrypt for agents)\n-\n**No trust** → Sentinel audit score (0-10) in every card\n-\n**No encryption** → Ed25519 public key in every card, all messages encrypted\n-\n**Language barrier** → Card specifies framework, MarketNow translates\n-\n**No payment** → USDC wallet in every card, x402 escrow\n\n##\nPricing\n\n-\n**Free**: Basic ATC with L1.5 audit, 100 API calls/day\n-\n**Pro** ($9.99/mo): L2.5 gVisor audited, encrypted messaging, 10K calls/day\n-\n**Enterprise** ($99/mo): L4 audited, custom trust policies, unlimited\n-\n**Transaction**: 5% fee on every paid task between agents\n\n##\nTry it\n\nFull spec: [marketnow.site/atc-spec.json](https://marketnow.site/atc-spec.json)\n\nDocumentation: [marketnow.site/atc](https://marketnow.site/atc)\n\n*ATC is part of *[MarketNow](https://marketnow.site) — the trust layer for agent commerce.
