Metamask: How to set up my own ganache provider in web3-react?

I can help you set up your own MetaMask provider using Web3 React. Here’s an example of how to do it:

Metamask: How to set up my own ganache provider in web3-react?

This example assumes you have a basic understanding of Web3 and React.

First, create a new MetaMaskProvider.js file in the same directory as your App.js or index.js file:

// MetaMaskProvider.js
import { ChainId, network } from '@web3-react/core';
import { MetaMask } from '@metamask-connected-web3 provider';
const provider = new MetaMask({ chainId: ChainId.SOLANA });
export default function MetaMaskProvider() {
return ;
}

Here’s what’s happening:

  • We import the ChainId and network constants from @web3-react/core.
  • We create a new instance of the MetaMask provider with an options object that includes the chain ID set to SOLANA. You can choose any supported chain ID (e.g. Etherscan, Polkadot, etc.).
  • We export a component called MetaMaskProvider that returns a MetaMask.Provider component wrapped in our provider instance.
  • In your App.js or index.js file, you can use the MetaMaskProvider like this:

import React from 'react';
import MetaMaskProvider from './MetaMaskProvider';
function App() {
return (
{/ Your app code here /}
);
}

Using Web3 React’s useWeb3Provider hook

Alternatively, you can use the useWeb3Provider hook provided by Web3 React to set up your own provider:

import { ChainId, network } from '@web3-react/core';
import { useWeb3Provider } from '@web3-react/ethers';
const provider = new ethers.providers.Web3Provider(window.ethereum);
const MetaMaskProvider = () => {
return ;
};

This hook returns a Web3Provider component that wraps your application with the current Ethereum provider.

Using the Web3 React Provider component

You can also create your own custom provider by extending the Provider component:

import { ChainId, network } from '@web3-react/core';
import { MetaMask, ethers } from 'ethers';
const MyMetaMaskProvider = () => {
const provider = new ethers.providers.Web3Provider(window.ethereum);
return ;
};

This will create a custom provider that wraps your application with the current Ethereum provider.

Hope this helps! Let me know if you have any questions or need further assistance.
