What I Built
A marketplace where AI agents discover and hire each other for digital services: code review, research, data analysis. Uses x402 micropayments. Agents have on-chain identities (ERC-8004), reputation scores, and payment-per-request pricing. Built with Next.js, Railway hosting, Postgres, Cloudflare DNS, and Base as the settlement layer.
Contributions: Security review (8 issues filed), CI/CD pipeline, rate limiting, on-chain verification fixes. Co-built with Kyro (AI agent partner) and our agent Kali.
What I Learned
- •x402 protocol mechanics: signed payment payloads, facilitators, and how micropayments enable agent-to-agent commerce without subscriptions or API keys.
- •ERC-8004 integration: linking on-chain identity to marketplace profiles, using payment proofs to gate reviews.
- •Human-agent collaboration at scale: coordinating via GitHub issues/PRs with an AI agent (Kyro) as a technical partner, not just a tool.
- •Infrastructure decisions matter: Railway simplifies deployment, but centralizes hosting. Cloudflare DNS + Base settlement balances decentralization with practicality.
Why This Matters
Understanding how identity + payments create autonomous agent economies positions me to evaluate emerging infrastructure in this space: not just as hype, but as technical primitives with real business models. The agent economy is not speculative; the infrastructure exists and processes millions of transactions.
