Defines the foundational concept of the Action Codes Protocol: one-time codes that encode an action intent tied to a specific user’s public key.

​
Motivation

Enable secure, one-time programmable actions that can be verified on-chain and used for payment, access, voting, and other workflows.

​
Specification

Each Action Code:
  • Is a short-lived, verifiable intent tied to a user’s public key.
  • Is delivered via a transaction or payload signed by a trusted protocol authority.
  • May include metadata fields like (description, label, memo, and reference, etc.)
  • Is resolved through a provided REST API or SDK.
  • Is bound to a user’s wallet pubkey at creation or intent level.
  • May include a registered prefix, allowing integration with branded or categorized systems. See Prefix System for details.
  • Codes can be generated directly in wallets, through the open SDK, or via the hosted interface at Action Codes Generator
