Web3 Components Library - DEPRECATED

Replaced with GoldRush Kit - https://github.com/covalenthq/goldrush-kit

This web3 library is powered by the Covalent Unified API and consists of useful React components to fetch any on-chain data across any of the 30+ Covalent supported blockchain networks.

These components do not require an active web3 provider since data is hosted, indexed and queried from the Covalent Network. However, an API Key is required to use them.

Please refer to the Covalent API reference for documentation on how the API works.

Quick Start

  1. Install with npm: npm install @covalenthq/web3-components or install with yarn: yarn install @covalenthq/web3-components

  2. Create an .env file and set the variable: REACT_APP_COVALENT_API_KEY=Your Covalent API Key

Note: React v18.0 and greater is required to use these components

Token balances demo

The <TokenBalances /> component provides a complete and paginated balances table with all the ERC20 tokens and NFTs for a given wallet address and chainId.

Required Props:

  • noNFTFetch: Defaults to true. Set to false to fetch all the NFT metadata, which may take some time.
  • quoteCurrency: Defaults to USD. Visit the API Reference to see the full list of quote currency options.

Sample code:

import { TokenBalances } from '@covalenthq/web3-components';

function App() {
  return(
    <div className="TokenBalances">
      <TokenBalances
        address="demo.eth"
