+caip: 24
+title: Asset Reference for the Cosmos Asset Namespace
+author: Theobold Frazier
+discussions-to: https://github.com/shapeshift/CAIPs/issues/1
+status: Draft
+type: Standard

+
+## Simple Summary
+
+This document is about the details of the Cosmos network 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 Cosmos chain native assets and ibc assets.
+
+## Motivation
+
+See [CAIP-19](https://github.com/ChainAgnostic/CAIPs/blob/master/CAIPs/caip-19.md).
+
+## Specification
+
+### Cosmos chain Native Asset Namespace
+
+An Asset Namespace called "native" that references Cosmos network blockchain native assets, allowing for unique identification on Cosmos chains with multiple native assets.
+
+### Cosmos chain IBC Asset Namespace
+
+An Asset Namespace called "ibc". It references Cosmos network blockchain Inter-Blockchain Communication Protocol assets.
+
+#### Multiple Native Asset Reference Definition
+
+The Asset Reference format for Cosmos chain native assets is the base denomination of the asset in the current `chain_id`.
+
+#### IBC Asset Reference Definition
+
+The Asset Reference format for Cosmos chain ibc assets is the ibc channel identifier for that asset.
+
+## Rationale
+
+The Asset Namespace using slip44 for Cosmos chains is insufficient for chains with multiple native assets like osmosis-1. Using the "native" namespace allows multiple native assets to have unique CAIP19s.
+
+## Backwards Compatibility
+
+Not applicable.
+
+## Test Cases
+
+This is a list of manually composed examples
+
+```
+# Native Atom Asset on the cosmoshub-4 chain
+cosmos:cosmoshub-4/slip44:118
+
+# Native Osmosis Asset on the osmosis-1 chain
+cosmos:osmosis-1/slip44:118
+
+# Native Ion Asset on the osmosis-1 chain
+cosmos:osmosis-1/native:uion
+
+# IBC Atom asset on the osmosis-1 chain
+cosmos:osmosis-1/ibc:27394FB092D2ECCD56123C74F36E4C1F926001CEADA9CA97EA622B25F41E5EB2
