Getting Started with Web SDK

Learn how to get started with Web SDK by installing the necessary packages and using the wagmi connectors to utilize an Embedded Wallet or Native EOA Wallet for authentication.

Setting Up your Dapp

To utilize the SequenceConnect wrapper for connecting web3 wallets to your application, follow these steps:

Web SDK is built on top of wagmi, so for advanced configurations, sending transactions, calling contracts, etc., please refer to the wagmi documentation.

Vite App

1. Create a React Project with Vite

   We will start by creating a React project with vite:

   npm create vite
   # or
   pnpm create vite
   # or
   yarn create vite
   
2. Install the Web SDK dependencies

   npm install @0xsequence/connect wagmi ethers@6.13.0 viem 0xsequence @tanstack/react-query
   # or
   pnpm install @0xsequence/connect wagmi ethers@6.13.0 viem 0xsequence @tanstack/react-query
   # or
   yarn add @0xsequence/connect wagmi ethers@6.13.0 viem 0xsequence @tanstack/react-query
   
3. Create a Config

   Next, a configuration variable for SequenceConnect will need to be created as waas (meaning an Embedded Wallet).

   First obtain a WaaS Config Key from the Sequence Builder and a project access key, then make sure your project origin is whitelisted in the Builder Embedded Wallet Configuration. If you want to allow WalletConnect you will also need a Wallet Connect ID. To setup Google Login follow the Google Configuration for Embedded Wallet.

   [config.ts]

   import { createConfig } from "@0xsequence/connect";
   
   export const config: any = createConfig("waas", {
     projectAccessKey: "<your-project-access-key>",
     chainIds: [1, 137],
     defaultChainId: 1,
     appName: "Demo Dapp",
     waasConfigKey: "<your-waas-config-key>", // for waas
     google: {
       clientId: "<your-google-client-id>",
     },
     walletConnect: {
       projectId: "<your-wallet-connect-project-id>",
     },
   });
   

   In order to customize further, you can view additional configuration parameters.

4. Setup Provider Component

   The configuration we created in step 3 needs to be passed into the providers below in the main.tsx.

   [main.tsx]

   import React from "react";
   import ReactDOM from "react-dom/client";
   import "index.css";
   
   import App from "./App";
   import { config } from "./config";
   import { SequenceConnect } from "@0xsequence/connect";
   
   function Dapp() {
     return (
       <SequenceConnect config={config}>
         <App />
       </SequenceConnect>
     );
   }
   
   ReactDOM.createRoot(document.getElementById("root")!).render(
     <React.StrictMode>
       <Dapp />
     </React.StrictMode>
   );
   
5. Trigger the Connection Modal

   [App.tsx]

   import './App.css'
   import { useOpenConnectModal } from '@0xsequence/connect'
   
   function App() {
     const {setOpenConnectModal} = useOpenConnectModal()
     
     return (
       <>
         <button onClick={() => setOpenConnectModal(true)}>Connect</button>
       </>
     )
   }
   
   export default App
   

   For web3 interactions, wagmi exposes a set of React hooks that make it convenient for common functions like sending transactions.

NextJS App

1. Create a NextJS Project

   We will start by creating a NextJS project with create-next-app:

   npx create-next-app@latest
   # or
   pnpm create next-app
   # or
   yarn create next-app
   
2. Install the Web SDK dependencies

   npm install @0xsequence/connect wagmi ethers@6.13.0 viem 0xsequence @tanstack/react-query
   # or
   pnpm install @0xsequence/connect wagmi ethers@6.13.0 viem 0xsequence @tanstack/react-query
   # or
   yarn add @0xsequence/connect wagmi ethers@6.13.0 viem 0xsequence @tanstack/react-query
   
3. Create a Config

   Next, a configuration variable for SequenceConnect will need to be created as waas (meaning an Embedded Wallet).

   First obtain a WaaS Config Key from the Sequence Builder and a project access key, then make sure your project origin is whitelisted in the Builder Embedded Wallet Configuration. If you want to allow WalletConnect you will also need a Wallet Connect ID. To setup Google Login follow the Google Configuration for Embedded Wallet.

   [src/app/config.ts]

   import { createConfig } from "@0xsequence/connect";
   
   export const config = createConfig("waas" /*or, 'universal'*/, {
     projectAccessKey: "<your-project-access-key>",
     chainIds: [1, 137],
     defaultChainId: 1,
     appName: "Demo Dapp",
     waasConfigKey: "<your-waas-config-key>", // for waas
     google: {
       clientId: "<your-google-client-id>",
     },
     walletConnect: {
       projectId: "<your-wallet-connect-project-id>",
     },
   });
   

   In order to customize further, you can view additional configuration parameters.

4. Setup Provider Component

   The configuration we created in step 3 needs to be passed to the SequenceConnect provider.

   Create a separate “providers.tsx” file to wrap your app in the Providers component.

   [src/app/providers.tsx]

   "use client";
   
   import React from "react"
   import { config } from "./config"
   import { SequenceConnect } from "@0xsequence/connect"
   
   const Providers = ({ children }: { children: React.ReactNode }) => {
       return (
           <SequenceConnect config={config}>
               {children}
           </SequenceConnect>
       )
   }
   
   export default Providers;
   
5. Wrap your App in the Providers

   Wrap your app in the Providers component.

   [src/app/layout.tsx]

   import type { Metadata } from "next";
   import { Geist, Geist_Mono } from "next/font/google";
   import "./globals.css";
   import Providers from "./providers";
   
   const geistSans = Geist({
     variable: "--font-geist-sans",
     subsets: ["latin"],
   });
   
   const geistMono = Geist_Mono({
     variable: "--font-geist-mono",
     subsets: ["latin"],
   });
   
   export const metadata: Metadata = {
     title: "Create Next App",
     description: "Generated by create next app",
   };
   
   export default function RootLayout({
     children,
   }: Readonly<{
     children: React.ReactNode;
   }>) {
     return (
       <html lang="en">
         <body
           className={`${geistSans.variable} ${geistMono.variable} antialiased`}
         >
           <Providers>
             {children}
           </Providers>
         </body>
       </html>
     );
   }
   
6. Trigger the Connection Modal

   [App.tsx]

   "use client"
   
   import { useOpenConnectModal } from '@0xsequence/connect'
   
   function Home() {
     const { setOpenConnectModal } = useOpenConnectModal()
   
     return (
       <>
         <button onClick={() => setOpenConnectModal(true)}>Connect</button>
       </>
     )
   }
   
   export default Home
