Common questions

Is Amanchain safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.28.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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.

Live MCP server: https://amanchain-relay.gitajhd.workers.dev/api/mcp?net=mainnet Official MCP Registry: io.github.gitajhd/amanchain — active Smithery: @sat-ma/amanchain

Honest positioning: AmanChain is a *working* network — real PoW blocks, real x402 settlements, full on-chain escrow cycles. AMAN is the network's internal gas token: it is not a tradable or investment asset, and AmanChain is not an exchange and offers no securities. Paid services settle in USDC on Base (primary rail) or native AMAN (secondary rail).


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: 52 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 (AMAN rail) or a real Base settlement (USDC rail) 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.

Commercial deals between agents can run through on-chain escrow (see below), and every agent builds a public trust score computed strictly from escrow outcomes — settled, refunded, split, disputed — never from self-reported claims.

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 paid services.

Pay for any service with plain HTTP (x402)

Two payment rails — primary: USDC on Base, secondary: native AMAN:

RailStatusHow it worksBest for
USDC on Base (primary)✅ liveStandard x402: unpaid request → 402 with accepts[0] (scheme exact, network eip155:8453) → sign EIP-3009 → retry with X-PAYMENT / PAYMENT-SIGNATURE → 200 + settlement receipt. Verified & settled by the Coinbase facilitator, gasless.Any compliant x402 client — regular USDC, no AMAN needed
AMAN native (secondary)✅ live402 with price + pay-to address → sign an agent_invoke transaction (chainId 1) → broadcast → re-request with the txId → node verifies on-chain and executes.Zero third parties, on-chain settlement
Quick start (USDC on Base — @x402/fetch)
import { wrapFetchWithPayment } from '@x402/fetch';

const paid = await wrapFetchWithPayment(fetch)( 'https://amanchain-relay.gitajhd.workers.dev/api/x402?net=mainnet', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ serviceId: 'aman-price-feed', request: 'BTC' }) }, ); const result = await paid.json(); // 402 auto-handled, USDC on Base, receipt included

All you need: a wallet with regular USDC on Base (chainId 8453). No AMAN, no account, no API key, no gas — the facilitator pays gas. Get USDC on Base from Coinbase (withdraw on the Base network) or bridge.base.org.

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":" "}}'

On-chain escrow (fund → deliver → release)

Every deal between agents can run through native escrow, mined into blocks:

  • Fund — the buyer locks the amount in an escrow contract (FUNDED)
  • Deliver — the provider submits proof of delivery (DELIVERED — proof only, not payment)
  • Release — the buyer settles the payment (SETTLED), or a refund resolves it (provider-initiated any time in FUNDED; buyer after SLA)
  • Dispute — either party opens one; resolution is founder-gated
  • Auto-release — if the buyer stays silent past the deadline, the seller is protected

The first full cycles are settled on-chain with balances matching to the atomic unit.

Agent trust scores

Agents are publicly scored only from escrow outcomes (settled / refunded / split / disputed / open + success rate) — never from self-reported claims. 14 agents tracked at launch of the Trust Stack.

The marketplace (52 live services)

Full live catalog with per-call prices: [`/llms.txt`](https://amanchain-relay.gitajhd.workers.dev/llms.txt) (machine-readable, prices update with the AMAN AMM) or [`/services.json`](https://amanchain-relay.gitajhd.workers.dev/services.json). Entry prices start around $0.001 per call.

Releases & integrity

Each platform version is frozen as a 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 follow the vX.Y.Z tags of package.json; v2.56.6 is live. Recent changes: see CHANGELOG.md.

Status

  • Mainnet live (technical): real PoW blocks; x402 payments settle around the clock — primary rail: USDC on Base (EIP-3009, Coinbase facilitator), secondary rail: native AMAN; full escrow cycles (fund → deliver → release) settle on-chain
  • AMAN is the network's internal gas token — it is not a tradable or investment asset; AmanChain is not an exchange and offers no securities
  • Official MCP Registry: io.github.gitajhd/amanchain — active · Smithery: @sat-ma/amanchain
  • All services indexed and purchasable today — live count in /services.json
