Prove you can build on this
Twenty-five questions across the eight domains an engineer has to get right to work on an agentic interoperability layer. It runs in your browser, it stores nothing, and every answer comes with its reasoning.
Developer certification
25 questions. 80% to pass.
Eight domains, drawn from what an engineer actually has to get right to build on this stack: protocol fundamentals, transport and statelessness, the pre-execution firewall, sandboxing, memory architecture, erasure, settlement, and WebMCP. Every question shows its reasoning after you submit — a wrong answer you understand is worth more than a right one you guessed.
