Simple Summary

This document is about the details of the SLIP44 asset namespace and reference for CAIP-19.

Abstract

In CAIP-19 a general asset identification scheme is defined. This is the implementation of CAIP-19 for SLIP44 (referencing native fungible coins).

Motivation

See CAIP-19.

Specification

SLIP44 Asset Namespace

The asset namespace is called "slip44" as in SLIP44. It reference native fungible coins of most of the existing blockchains.

Asset Reference Definition

The definition is delegated to SLIP44. The format is an unsigned integer in decimal representation and corresponds to index of SLIP44.

Note: due to length restrictions of the reference field (64 characters), the largest supported index is 9999999999999999999999999999999999999999999999999999999999999999.

Rationale

The index defined in SLIP44 is the most widely used coin identifier to the authors. It strives for uniqueness for native coins.
