Hands-On Blockchain for AI Agents
AI agents are beginning to transact on their own, but autonomous payments introduce serious security and control challenges.
This workshop shows you how agent payments actually work, how to build one using x402, and how to harden it against real-world risks such as replay attacks, wallet abuse, and unauthorized actions.
What You’ll Get
Hands-on experience building an end-to-end agent payment flow
A practical understanding of HTTP 402 and x402
Experience exposing payment functionality through MCP
Real attack scenarios and failure modes
Security patterns for spend limits, allowlists, audit trails, and kill switches
Runnable reference code you can extend after the workshop
Key Takeaway
You’ll leave with a working mental model of agent payments, runnable reference code, and the security patterns needed to distinguish a compelling demo from something that could realistically be shipped into production.
