With x402 on Aptos, we're unlocking pay-per-request APIs, autonomous agents that pay each other, and consumer apps that finally ditch subscriptions.
This list is not complete nor exclusive. It is meant to excite you about the kinds of things you can build this weekend. Choose from one or chose from several! Or invent your own!
"Make x402 easy, observable, and production-ready on Aptos"
We need teams who want to build the plumbing that makes x402 usable by the next 100k developers on Aptos. This is your chance to build the foundational tools everyone else will use. This track focuses on the projects that make x402 integration seamless for thousands of developers.
Purpose
Build the foundational tools and infrastructure that enable developers to integrate x402 payments into their applications. This track focuses on completing the missing Aptos implementation and creating developer-friendly tooling.
Payment analytics and dashboards
Build tools that make x402 payment flows visible and debuggable. Where did the money go? Why did a payment fail? Show developers what's happening.
Better developer experience
Create CLIs, SDKs, middleware, or templates that make integrating x402 straightforward. Think "npx create-x402-app" level simplicity.
Production-ready plugins
Rate limiting, dynamic pricing, retries, caching, auth middleware - all the stuff real APIs need.
Managed facilitator services
What if developers didn't have to run their own payment infrastructure? Build the Stripe of x402.
Testing and simulation
Mock payment environments, load testing tools, or simulators so developers can test without spending real money.
Monitoring and observability
Real-time monitoring for payment health, failed transactions, revenue analytics, and alerts.
