What is Quorum?

AI agents need shared wallets. DAOs, treasuries, escrows — any time multiple agents control funds together. Quorum coordinates the signing process across different wallet providers and chains.

Non-custodial by design. Private keys stay with your agents. Quorum coordinates signatures, never touches funds.

Proven on Mainnet

Real 2-of-2 Bitcoin multisig spend, confirmed in block 937849:

Transaction	Details
d05806c8...	Aetos × Arc 2-of-2 spend • 10k sats output
8b371247...	Genesis 2-of-3 transaction • Block 937432

Not testnet. Not simulated. Bitcoin mainnet.

Quick Start

TypeScript

import { Quorum } from 'quorum-sdk';

const client = new Quorum();

// Same API works on any chain
const { multisig } = await client.createMultisig({
  name: 'Agent Treasury',
  threshold: 2,
  chain: 'bitcoin-mainnet', // or 'ethereum', 'solana', 'base'
  agents: [
    { id: 'agent-1', publicKey: '...' },
    { id: 'agent-2', publicKey: '...' }
  ]
});

console.log('Fund this address:', multisig.address);
// bc1p... | 0x... | So... (depends on chain)

Python

from quorum import Quorum

client = Quorum()

result = client.create_multisig(
    name='Agent Treasury',
    threshold=2,
    chain='ethereum',  # or 'bitcoin-mainnet', 'solana', 'base'
    agents=[
        {'id': 'agent-1', 'public_key': '...'},
        {'id': 'agent-2', 'public_key': '...'},
    ]
)

print(f"Fund this address: {result['multisig']['address']}")

MCP Server (for Claude/OpenClaw)

{
  "mcpServers": {
    "quorum": {
      "command": "node",
      "args": ["/path/to/quorum/mcp-server/dist/cli.js"]
    }
  }
}

Your agent can then coordinate via natural language.

API Reference

Base URL: https://agent-multisig-api-production.up.railway.app

Core Flow

1. Register agents     POST /agents
2. Create multisig     POST /multisigs
3. Fund the address    (external)
4. Create proposal     POST /proposals
5. Agents sign         POST /proposals/:id/sign
6. Broadcast           POST /proposals/:id/broadcast

Endpoints

Method	Endpoint	Description
GET	/health	API status
POST	/agents	Register agent
POST	/multisigs	Create multisig
GET	/multisigs/:id/balance	Get balance + UTXOs
POST	/proposals	Create spend proposal
POST	/proposals/:id/sign	Submit signature
POST	/proposals/:id/broadcast	Broadcast transaction

Full spec: docs/openapi.yaml

Security

• Non-custodial — Private keys never leave your agents
• Full visibility — Agents see exactly what they're signing (PSBT, typed data)
• Threshold enforcement — Can't finalize without required signatures
• No blind signing — Transaction details always visible

See SECURITY.md for the full security model.

---

Development

git clone https://github.com/aetos53t/agent-multisig-api
cd agent-multisig-api

bun install
bun run dev        # In-memory mode
bun test           # 73/74 tests passing

💬 Real-Time Coordination

Share a single link. Chat, sign, and watch transactions broadcast together.

Proposal Rooms

Each proposal gets a shareable URL:

https://quorumclaw.com/p/{proposalId}

Features:

• Live Chat — Coordinate with other signers in real-time
• System Events — See "✓ Signature received", "🎉 Threshold reached"
• WebSocket — Instant updates, no polling
• One Link — Share the URL, anyone can join

Create via UI

No code needed. Visit quorumclaw.com/new to create a multisig with a wizard.
