Cosmos Wallet Registry

The wallet registry for the Cosmos Blockchain Ecosystem

Wallet Data

Wallet data contains information needed to allow dApps to associate wallets with chains.

Supported Chains

Supported chains must be registered to the Cosmos Chain Registry, and should be written exactly as defined in the Chain Registry (as folder name or chain_name). E.g., use 'cosmoshub', not 'Cosmos Hub'.

A wallet provider only needs a single file if the list of supported chains is identicial on all platforms, but may instead need to create multiple files, one for each platform with a unique set of supported chains. E.g., since Keplr's browser extensions support a different set of chains than their mobile apps support, they instead have two files: keplrextension.json and keplrmobile.json, each defining a different set of supported chains.

Features

The 'features' array contains allows a limited set of features to be defined:

suggest-chain: referes to an experimental suggest chain feature. E.g., See Keplr's: https://docs.keplr.app/api/suggest-chain.html
get-supported-chains: a feature that returns a list of chains supported by the wallet.

Platforms

A platform object is defined by several properties:

device: (desktop, mobile, tablet, other)
type: (application vs extension)
platform (the system on which the software runs): (ios, android, chrome, firefox, otherOS, otherBrowser)

The install_link is optional, but is a good way to confirm to users they've found the correct installation. Try to avoid language-specific url parameters in the URL.

Example

Here is an example wallet entry:

  "$schema": "../wallet.schema.json",
  "wallet_name": "keplrmobile",
  "pretty_name": "Keplr",
  "website": "https://www.keplr.app/",

  "supported_chains": [
    "cosmoshub",
    "osmosis"
  ],
  "features": [
    "suggest_chain",
    "icns"
    "get_supported_chains"
