Cosmos chain registry ⚛️

chain-registry

The npm package for the Official Cosmos chain registry

npm install chain-registry

A unified store of chains info, assets, asset lists, and IBC channels for the Cosmos ecosystem. Get everything from token symbols, logos, and IBC denominations for all assets you want to support in your application.

example

Fetch data from chain-registry:

import { assets, chains, ibc } from 'chain-registry';

const assetList = assets.find(({chain_name})=>chain_name==='osmosis');

console.log(assetList);

will output:

{
  '$schema': '../assetlist.schema.json',
  chain_name: 'osmosis',
  assets: [
    {
      description: 'The native token of Osmosis',
      denom_units: [Array],
      base: 'uosmo',
      name: 'Osmosis',
      display: 'osmo',
      symbol: 'OSMO',
      logo_URIs: [Object],
      coingecko_id: 'osmosis'
    },
    {
      denom_units: [Array],
      base: 'uion',
      name: 'Ion',
      display: 'ion',
      symbol: 'ION',
      logo_URIs: [Object],
      coingecko_id: 'ion'
    }
  ]
}

Dynamically fetch data:

import { ChainRegistryClient } from '@chain-registry/client';

// create an instance of ChainRegistryClient by passing in the chain names
const client = new ChainRegistryClient({
  chainNames: [
    'osmosis',
    'juno',
    'stargaze'
  ]
});

// chain info, assets and ibc data will be downloaded dynamically by invoking fetchUrls method
await client.fetchUrls();
// get chain data
const chain = client.getChain('osmosis');
// get asset list
const assetList = client.getChainAssetList('osmosis');
// get ibc data
const ibcData = client.getChainIbcData('osmosis);
// get asset list (including ibc assets)
const generatedAssetList = client.getGeneratedAssetLists('osmosis);
