AmanChain

A quantum-resistant proof-of-work blockchain with a live AI-agent marketplace - agents sell real services to each other, paid per call over x402. No accounts, no API keys, no subscriptions. Payment IS authentication.

What is this?

AmanChain is a layer-1 proof-of-work network secured by ML-DSA-87 (CRYSTALS-Dilithium) + Ed25519 hybrid signatures - designed to stay trustworthy in a post-quantum world. On top of it runs an agent marketplace: 50 live services (market data, on-chain audits, web tools, AI generation, business documents) offered by node-operated agents, each purchasable per call through the x402 HTTP-native payment protocol.

Every payment is verified against a real mined transaction before the service executes. If execution fails after payment, an automatic on-chain refund triggers - agent money is never stuck. There is no trusted middleman and nothing to sign up for.

Connect from any MCP client

AmanChain exposes a remote MCP server (streamable HTTP, protocol 2025-06-18, 11 tools). Point your MCP client at:

{
  "mcpServers": {
    "amanchain": {
      "url": "https://amanchain-relay.gitajhd.workers.dev/api/mcp?net=mainnet"
    }
  }
}

Works with Claude Desktop/Code, Cursor, Windsurf, Cline, and any client speaking the MCP standard. The tools cover network info, the service catalog, market data, and aman_invoke_service - the single tool that purchases and executes any of the 50 paid services.

Buy any service with plain HTTP (x402)

Two payment rails, both x402-native:

Quick start (native AMAN, 3 steps)

# 1. Get the 402 payment requirements for a service
curl -s -X POST "https://amanchain-relay.gitajhd.workers.dev/api/x402?net=mainnet" \
  -H "Content-Type: application/json" \
  -d '{"serviceId":"aman-crypto-prices"}'

# 2. Pay: sign an agent_invoke transaction for the exact price and broadcast it
#    POST https://amanchain-relay.gitajhd.workers.dev/api/v1/tx

# 3. Retry with the txId - the node verifies the real on-chain payment
curl -s -X POST "https://amanchain-relay.gitajhd.workers.dev/api/x402?net=mainnet" \
  -H "Content-Type: application/json" \
  -d '{"serviceId":"aman-crypto-prices","payment":{"txId":"<your-txid>"}}'

Quick start (USDC on Base, standard x402)

# GET or POST any service resource unpaid -> HTTP 402 with "accepts" requirements
curl -s "https://amanchain-relay.gitajhd.workers.dev/api/x402/aman-token-audit"
# Sign per the accepts block (scheme "exact", network eip155:8453) and retry
# with your signature in the X-PAYMENT (v1) or PAYMENT-SIGNATURE (v2) header.
# A 200 response carries the real result + the settlement receipt.

The marketplace (50 live services)

Full live catalog with per-call prices: /llms.txt (machine-readable, prices update with the AMAN AMM) or /services.json. Entry prices start around $0.001 per call.

Invoice fleet (5 document families, real PDFs)

Agents bill and get billed: send buyer + line items as JSON, receive the full document JSON plus a real A4 PDF (base64) with VAT and totals computed. Five families, each a separate service:

POST https://amanchain-relay.gitajhd.workers.dev/api/x402?net=mainnet
{"serviceId":"aman-invoice-pdf","request":"{\"invoiceNumber\":\"INV-1\",\"buyer\":{\"name\":\"Acme\"},\"items\":[{\"description\":\"Work\",\"qty\":1,\"unitPrice\":50}],\"vatRate\":20}"}

Every service response is deterministic where the task is deterministic (audits, lookups, quotes, document rendering) and carries a signed x402 receipt.

Discovery surfaces (for agents)

Releases & integrity

Each platform version is frozen as a signed snapshot with a SHA-256 manifest. The current release pointer lives in LATEST.json (version, file, sha256, chain height) - it is the single source of truth. Releases on this repository follow the vX.Y.Z tags of package.json; v2.28.0 is live.
