move-patterns

What problem does it solve?

Design patterns provide reusable, battle-tested structures to build robust Move modules, reducing boilerplate and errors.

Core Features & Use Cases

• Events: emit and observe state-changing changes for off-chain clients.
• Error Handling: define typed errors and messages to surface precise failure conditions.
• One-Time Witness (OTW) Pattern: use unique, uncopyable objects to prove publication and ownership.
• Capability Pattern: gate privileged functions with capabilities to improve composability and security.
• Pure Functions and Composability: keep core logic pure and return results for easy composition across contracts.

Quick Start

Create a Move module implementing an event, an error, and a simple OTW-capability pattern to demonstrate composability.
