Ora ABI Specification v0.1

The complete Application Binary Interface (ABI) specification for Ora contracts.

Overview​

Ora ABI is a professional, tooling-first interface layer for smart contracts, with strong support for UI/UX, code generation, and stable type identities.

Ora ABI is split into two layers:

  1. Manifest (authoritative): a self-describing interface + type graph + metadata.
  2. Wire profiles (optional): concrete byte encoding rules used for calls/returns/errors/events.
