Usage

Using the chain-registry

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'
    }
  ]
}

Using the @chain-registry/client for dynamic data

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');
