Track 2 — Agentic Commerce & Payment Infrastructure:

Develop core infrastructure that enables secure and scalable autonomous payments between AI agents and digital services. Example ideas include x402 Payment Gateway, Multi-Tenant Payment Platform, Agent Payment Router, Spend Policy Engine, Receipt Verification Service, Payment Analytics Dashboard, Agent Reputation System, and Service Registry & Marketplace.

Track 3 — Developer Tools & SDKs:

Build tools that make developing, testing, debugging, and deploying x402 applications easier. Example ideas include x402 CLI, Next.js Starter Kit, Payment Flow Simulator, API Monetization Plugins, Transaction Debugger, Deployment Toolkit, Client SDK Extensions, and Smart Contract Templates.

Track 4 — DeFi, Web3 & Tokenized Finance:

Create decentralized financial applications and blockchain-powered systems using x402 and Web3 technologies. Example ideas include Decentralized Payment Platform, Streaming Payments, Stablecoin Payment Solutions, Cross-Border Payments, Escrow Services, Tokenized Assets Marketplace, Subscription Alternatives with x402, and Web3 Wallet Integrations.

Track 5 — Open Innovation:

Build any solution that leverages x402 and blockchain technology to solve real-world problems.
