x402-solana: Complete x402 Protocol Implementation for Solana
Version 2.0.0
The x402-solana SDK provides a dominant, end-to-end implementation of the HTTP 402 Payment Required protocol, enabling seamless, autonomous, and instant payments on the Solana blockchain using USDC.
This library is designed for both clients (autonomous agents) that need to pay for resources and servers (APIs/services) that need to monetize their endpoints.
✨ Features and Hackathon Category Coverage
The SDK is structured to address all five hackathon categories:
| Category | Component | Description |
|---|---|---|
| 1. Agent Identity & Reputation | AgentRegistry, IdentityVerifier |
Decentralized identity and reputation scoring for agents using Solana wallet as the root of trust. |
| 2. Agent-to-Agent Marketplace | A2AMarketplace, ServiceOrchestrator |
Advanced P2P marketplace for agents to discover, request, and trade services with automatic payment handling. |
| 3. MCP Servers | MCPPaymentServer, AgentMCPServer |
Model Context Protocol integration, allowing AI models (e.g., GPT, Claude) to use paid tools and services autonomously. |
| 4. SDKs & Infrastructure | PaymentRouter, PaymentCache, BatchProcessor |
High-performance infrastructure components for routing, caching, and batching x402 payments. |
| 5. Practical AI Applications | AIToolkit, AIAssistant, AITrader |
Specialized AI agent frameworks built on the core protocol, demonstrating real-world payment use cases. |
