Welcome to the Wonderland's OP Handbook ✨

Whether you’re here to ship a feature, reason through protocol design, or audit smart contracts that power interop across L2s, this guide is for you. It distills core knowledge about the OP Stack, technical architecture, governance models, and the shared practices that shape how we work together.

OP is a protocol for scaling Ethereum and expanding what’s possible. That mission demands thoughtful engineering, good security hygiene, clear specs, and fearless curiosity. This handbook helps you get there 🪄

You’ll find:

• An introduction to the OP Stack and how its components interact
• Deep dives into interop, governance, and fault proof infrastructure
• Examples and guidelines for writing specs, PRs, and design docs
• Tips from past contributors to help you avoid common pitfalls

This is a living document. It grows with the stack, shaped by every dev who joins.
