A2A SHIB Payment System - OpenClaw Skill

Framework-agnostic agent-to-agent payment infrastructure on Polygon network.

Summary

This skill enables AI agents to:

  • 💰 Send/receive SHIB payments on Polygon (~$0.003 gas)
  • 🔒 Create trustless escrow contracts
  • 💬 Negotiate prices automatically (multi-round)
  • ⭐ Build reputation through ratings
  • 🌐 Discover other agents via A2A protocol

9,416x cheaper than traditional escrow services (Escrow.com charges $28.25 per $100, this costs $0.003).

Features

Payment System

  • Direct SHIB transfers on Polygon
  • Sub-penny gas costs (~$0.003)
  • Balance checking
  • Transaction history

Escrow System

  • Time-locked trustless payments
  • Multi-party approval required
  • Delivery proof submission
  • Automatic release when conditions met
  • Dispute resolution with arbiter
  • 6-state machine: pending → funded → locked → released/refunded/disputed

Price Negotiation

  • Service quote creation
  • Multi-round counter-offers
  • Accept/reject workflow
  • Automatic escrow integration
  • Service delivery tracking

Reputation System

  • Star ratings (0-5) with reviews
  • Dynamic trust scores (0-100)
  • Trust levels: new → bronze → silver → gold → platinum
  • Achievement badges
  • Agent verification

Security Layer

  • API key authentication (64-byte keys)
  • Rate limiting (requests + payments + volume)
  • Immutable audit logging (hash-chained)
  • Per-agent permissions & limits

Installation

# Via ClawHub
clawhub install a2a-shib-payments

# Or manual clone
cd ~/clawd/skills
git clone https://github.com/marcus20232023/a2a-shib-payments.git
cd a2a-shib-payments
npm install

Configuration

Create .env.local:

cp .env.example .env.local
nano .env.local

Required environment variables:

  • WALLET_PRIVATE_KEY - Your Polygon wallet private key
  • RPC_URL - Polygon RPC endpoint (default: https://polygon-rpc.com)
  • SHIB_CONTRACT_ADDRESS - SHIB token contract (default: 0x95ad61b0a150d79219dcf64e1e6cc01f0b64c4ce)

Usage

Start the Agent

node a2a-agent-full.js

Agent runs on port 8003 by default.

OpenClaw Integration

The agent exposes A2A protocol endpoints that OpenClaw can communicate with:

Agent Card: http://localhost:8003/.well-known/agent-card.json

Example commands from OpenClaw:

// Check balance
const result = await fetch('http://localhost:8003/a2a/jsonrpc', {
  method: 'POST',
  headers: {'Content-Type': 'application/json'},
  body: JSON.stringify({
    jsonrpc: '2.0',
    method: 'message/send',
    params: {
      message: {
        kind: 'message',
        messageId: '1',
        role: 'user',
        parts: [{kind: 'text', text: 'balance'}]
      }
    },
    id: 1
  })
});

// Send payment
// text: 'send 100 SHIB to 0x...'

// Create escrow
// text: 'escrow create 500 SHIB for data purchase payee data-agent'

// Check reputation
// text: 'reputation check data-agent'

Framework Compatibility

Works with:

  • ✅ OpenClaw - As a skill or standalone agent
  • ✅ LangChain - Via A2A tools
  • ✅ AWS Bedrock - Via agent invocation
  • ✅ AutoGen - Via A2A messaging
  • ✅ Any A2A-compatible system

See INTEGRATION-EXAMPLES.md for detailed integration guides.

Use Cases

Data Marketplace

// Research agent buys Tesla historical data
const quote = await negotiation.createQuote({
  service: 'TSLA 2020-2025 historical data',
  price: 500  // SHIB
});

// Counter-offer and accept
await negotiation.counterOffer(quote.id, 'research-agent', 400);
await negotiation.acceptCounter(quote.id, 'data-provider');
// Escrow created automatically

AI Model Training

// Create escrow for model training job
const escrow = await escrowSystem.create({
  payer: 'startup-agent',
  payee: 'ai-trainer',
  amount: 1000,
  purpose: 'Train GPT-style model',
  conditions: {requiresDelivery: true},
  timeoutMinutes: 720  // 12 hours
});

API Endpoints

A2A Protocol

  • /.well-known/agent-card.json - Agent capabilities
  • /a2a/jsonrpc - JSON-RPC messaging
  • /a2a/rest/* - REST API

Commands (via message text)

  • balance - Check SHIB balance
  • send [amount] SHIB to [address] - Send payment
  • escrow create [amount] SHIB for [purpose] payee [agent] - Create escrow
  • escrow fund [id] - Fund escrow
  • escrow release [id] - Release funds
  • quote create [service] [price] - Create price quote
  • reputation check [agentId] - Check agent reputation
  • rate [agentId] [1-5] [review] - Rate an agent
