web3-toolkit-react v0.5.1

web3-toolkit-react

Web3 Toolkit for React

Install

The library depends on the ethers package so install it first:

npm install --save ethers

Also make sure you use react >= 16.14.0.

Finally install the library:

npm install --save web3-toolkit-react

Quick start

1. Setup a Web3Provider to share session variables (address, network etc) across your app.

It is not required but strictly recommended to create an Ethereum provider and pass it to Web3Provider.

Don't get confused:

• Web3Provider provides React context
• Ethereum provider provides data from the Ethereum network, read more in ethers library documentation

import { Web3Provider} from 'web3-toolkit-react';

...

const alchemyProvider = new ethers.providers.AlchemyProvider(
  NETWORK_NAME,
  ALCHEMY_API_KEY
);

<Web3Provider provider={alchemyProvider}>
    <App />
</Web3Provider>

2. Use components and hooks:

import { Address, useMetaMask, useAddress, useChain } from 'web3-toolkit-react';

const App = () => {
  const { status, error, connect } = useMetaMask();
  const address = useAddress();
  const chain = useChain();

  return (
    <div>
      <button onClick={connect}>{status}</button>
      <Address>{address}</Address>
      <div>{chain?.name}</div>
    </div>
  );
};
