Welcome to x402 on Solana
AI-Powered Payments for the Autonomous Web

Experience real on-chain payments, autonomous agents, and decentralized commerce — all powered by Solana, x402, MCP tools, and the Google ADK. Build, test, and deploy AI agents that can transact, charge, and verify payments — automatically.

The future of commerce is agent-to-agent

x402 unlocks autonomous payment flows where agents can request, verify, and execute cryptocurrency payments in real time — no manual steps, no API sprawl, no centralized control. Powered by Solana devnet/mainnet, SPL tokens, USDC, Google ADK, and x402 Payment Required Protocol.

Solana Integration

  • • On-chain transaction verification and explorer links
  • • Instant settlement with USDC SPL tokens
AI Tools & Agent Framework
Everything you need to build revenue-generating autonomous agents.
  • • Preconfigured agents built with Google ADK
  • • Merchant & buyer agent templates
  • • Rich tools for actions, payments, sessions, tracing
  • • MCP server, payment testing tools, debugging utilities
  • • Local & cloud-based agent execution
x402 Payment Protocol
The first payment spec designed for AI ↔ AI commerce.
  • • Machine-verifiable payment requests
  • • Price negotiation or fixed pricing

How It Works

A simple 4-step process for autonomous agent-to-agent commerce

1
The agent requests payment
Client agent sends an x402 request with item, amount, and merchant metadata.
2
User approves & signs
User signs the transaction in Phantom/Solflare or via programmatic signing.
3
Solana processes the transaction
Fast finality and cheap fees make it instant for AI-driven commerce.
4
Merchant agent receives confirmation
The merchant agent verifies the signature and continues the workflow.

Issue item • Return digital asset • Unlock service • Provide receipt

Everything is automated.
