A single Web3 / Ethereum provider solution for all Wallets

Introduction

Web3Connect is an easy-to-use library to help developers add support for multiple providers in their apps with a simple customizable configuration.

By default Web3Connect Library supports injected providers like (Metamask, Dapper, Gnosis Safe, Web3 Browsers, etc) and WalletConnect, You can also easily configure the library to support Fortmatic, Squarelink, and Portis.

Preview

You can test the library on: https://web3connect.com/

Usage

1. Install Web3Connect NPM package

npm install --save web3connect

# OR

yarn add web3connect

2. Install Provider packages

npm install --save @walletconnect/web3-provider @portis/web3 fortmatic squarelink

# OR

yarn add @walletconnect/web3-provider @portis/web3 fortmatic squarelink

3. Then you can integrate it three different ways:

• React Button
• Core Module
• Individual Connectors

React Button

Add Web3Connect Button to your React App as follows

import Web3Connect from "web3connect";

<Web3Connect.Button
  network="mainnet" // optional
  providerOptions={{
    walletconnect: {
      infuraId: "INFURA_ID" // required
    },
    portis: {
      id: "PORTIS_ID" // required
    },
    squarelink: {
      id: "SQUARELINK_ID" // required
    },
    fortmatic: {
      key: "FORTMATIC_KEY" // required
    }
  }}
  onConnect={(provider: any) => {
    const web3 = new Web3(provider); // add provider to web3
  }}
  onClose={() => {
    console.log("Web3Connect Modal Closed"); // modal has closed
  }}
/>;

Core Module

Add Web3Connect Core to your Dapp as follows

import Web3Connect from "web3connect";

const web3Connect = new Web3Connect.Core({
  network: "mainnet", // optional
  providerOptions: {
    walletconnect: {
      infuraId: "INFURA_ID" // required
    },
    portis: {
      id: "PORTIS_ID" // required
    },
    squarelink: {
      id: "SQUARELINK_ID" // required
    },
    fortmatic: {
      key: "FORTMATIC_KEY" // required
    }
  }
});

// subscribe to connect
web3Connect.on("connect", (provider: any) => {
  const web3 = new Web3(provider); // add provider to web3
});

// subscribe to close
web3Connect.on("close", () => {
  console.log("Web3Connect Modal Closed"); // modal has closed
});

web3Connect.toggleModal(); // open modal on button click

Individual Connectors

Add individual connectors for each provider to your own UI (no modal provided)

import Web3Connect from "web3connect";

// For inject providers in dapp browsers
const provider = await Web3Connect.ConnectToInjected();

// For WalletConnect
const provider = await Web3Connect.ConnectToWalletConnect({
  infuraId: "INFURA_ID", // required
  bridge: "https://bridge.walletconnect.org" // optional
});

// For Squarelink
const provider = await Web3Connect.ConnectToSquarelink({
  id: "SQUARELINK_ID", // required
  network: "mainnet" // optional
});

// For Portis
const provider = await Web3Connect.ConnectToPortis({
  id: "PORTIS_ID", // required
  network: "mainnet" // optional
});

// For Fortmatic
const provider = await Web3Connect.ConnectToFortmatic({
  key: "FORTMATIC_KEY", // required
  network: "mainnet" // optional
});

Utils

function checkInjectedProviders(): IInjectedProvidersMap;
function getInjectedProviderName(): string | null;
function getProviderInfoByName(name: string | null): IProviderInfo;
function getProviderInfo(provider: any): IProviderInfo;
function isMobile(): boolean;
function formatProviderDescription(ProviderInfo: IProviderInfo);

Types

interface IProviderInfo {
  name: string;
  type: string;
  logo: string;
  check: string;
  styled: {
    [prop: string]: any;
  };
}

interface IProviderOptions {
  [providerName: string]: any;
}

interface IEventCallback {
  event: string;
  callback: (result: any) => void;
}

interface IInjectedProvidersMap {
  injectedAvailable: boolean;
  [isProviderName: string]: boolean;
}
