Web3-connect-react is a React library for seamless blockchain wallet integration across multiple networks.
It provides ready-made hooks and components for connecting popular wallets like MetaMask, OKX, Phantom, and WalletConnect,
with support for custom wallet providers.
The library simplifies Web3 interactions by managing wallet connections, network switching, and smart contract calls through a unified API.
Just wrap your app with WalletContextProvider
to access its complete functionality across your React components.
Online Demo: https://web3-connect.pagepreview.dev
Features
- Multiple chains support
- Multiple wallet support
- MetaMask
- OKX
- Phantom
- WalletConnect
- Custom providers
- Smart contract interaction
- Network switching
- Send transactions
- Event listeners (on network change, on account change)
Installation
pnpm install web3-connect-react
Usage
Wrap your application with the WalletContextProvider
and EnvironmentProvider
.
<EnvironmentProvider>
<WalletContextProvider
session={session}
walletConnectConfig={WalletConnectConfig}
>
{children}
</WalletContextProvider>
</EnvironmentProvider>
Use the sdk
Sign In
import { useWallet } from "web3-connect-react";
const { signIn, isSignedIn } = useWallet();
await signIn(providerName, {
onSignedIn: async (walletAddress, provider, session) => {
sessionStorage.setItem("session", JSON.stringify(session));
router.refresh();
},
getSignInData: async () => {},
});
Sign Out
import { useWallet } from "web3-connect-react";
const { signOut } = useWallet();
await signOut();
Call a Contract
import { useWallet } from "web3-connect-react";
const { sdk } = useWallet();
// deploy
const address = await sdk
.deployContract({
abi,
bytecode,
});
// call
const result = await sdk.callContractMethod({
contractAddress,
abi,
method: "balanceOf",
params: [walletAddress],
})
Implementing a Custom Provider
Implementing a custom provider is straightforward; you simply need to extend the BaseProvider
class. Below is an
illustrative example of a MetaMaskProvider
.
export class MetaMaskProvider extends BaseProvider {
// MetaData is used to display information about the provider in the modal
metadata: MetaData = {
name: "MetaMask",
image: <MetaMaskIcon/>,
description:
"Connect using a browser plugin or mobile app. Best supported on Chrome or Firefox.",
displayName: "MetaMask",
notInstalledText:
"Dear friend, If you don't have a wallet yet, you can go to install MetaMask and create one now.",
downloadLink: "https://metamask.io/",
};
// The rdns is used to identify the provider using the EIP-6963 event
rdns: string = "io.metamask";
constructor(globalWindow: any) {
super(globalWindow);
}
init() {
if (this.globalWindow === undefined) {
return;
}
// get the provider from the EIP-6963 event
this.globalWindow.addEventListener(
"eip6963:announceProvider",
(event: any) => {
const eipEvent = event as EIP6963AnnounceProviderEvent;
if (eipEvent.detail.info.rdns === this.rdns) {
this.provider = eipEvent.detail.provider;
}
}
);
this.globalWindow.dispatchEvent(new Event("eip6963:requestProvider"));
}
}
