TAIPs

Transaction Authorization Improvement Proposals (TAIPs) provide standards for the Transaction Authorization Protocol (TAP).

Please read the TAP Whitepaper for more context.

TAP is a decentralized protocol allowing multiple participants in real-world transactions to identify each other and collaborate with the goal of authorizing them safely.

The purpose of TAIPs is to provide the community with a means to propose enhancements to TAP extending it's capabilities to unique transaction scenarios.

Documentation

• Message Types and Data Structures - Comprehensive documentation of all TAP message types and data structures

Implementation Resources

JSON Schemas

All TAP message types have corresponding JSON Schema definitions available at:

• Base URL: https://taips.tap.rsvp/schemas/
• Local Path: ./schemas/

Example schemas:

• Transfer Message: https://taips.tap.rsvp/schemas/messages/transfer.json
• Payment Message: https://taips.tap.rsvp/schemas/messages/payment.json
• Party Structure: https://taips.tap.rsvp/schemas/data-structures/party.json

TypeScript Types

Official TypeScript type definitions are available as an npm package:

• Package: @taprsvp/types
• Source: ./packages/typescript/
• Installation: npm install @taprsvp/types

The package exports:

• All TAP message type interfaces
• Data structure types (Party, Agent, Policy, etc.)
• Common types (CAIP identifiers, ISO types, etc.)
• Full TypeScript support with comprehensive JSDoc comments

Inspiration

TAIPs are heavily inspired by TAIPs which in turn were heavily inspired by bips.
