Setting Up your Dapp

First make sure you have created a Sequence account, if you don’t have one, you can create one here, you will need your Project Access Key and Waas Config Key in order to use the Web SDK. 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
NextJS App

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

Install the Web SDK dependencies

npm install @0xsequence/connect @0xsequence/hooks wagmi ethers viem 0xsequence @tanstack/react-query
# or
pnpm install @0xsequence/connect @0xsequence/hooks wagmi ethers viem 0xsequence @tanstack/react-query
# or
yarn add @0xsequence/connect @0xsequence/hooks wagmi ethers viem 0xsequence @tanstack/react-query

Create a Config

Next, create the configuration.

If you want to allow WalletConnect you will also need a walletConnectProjectId.
To setup Google Login follow the Google Configuration for Embedded Wallet.
To setup Apple Login follow the Apple Configuration for Embedded Wallet.
To setup X (Twitter) Login follow the X (Twitter) Configuration for Embedded Wallet.
To setup Gues Mode follow the Guest Mode Configuration for Embedded Wallet.

[config.ts]

import { createConfig } from "@0xsequence/connect";

// Waas config
export const waasConfig: any = createConfig('waas', {
  projectAccessKey: "<your-project-access-key>",
  defaultTheme: 'dark',
  signIn: {
    projectName: 'Sequence Web SDK Demo',
  },
  appName: 'Sequence Web SDK Demo',
  chainIds: [1],
  defaultChainId: 1,
  waasConfigKey: 'waas-config-key',
  guest: true,
  email: true,
  google: {
    clientId 'your-google-client-id'
  },
  apple: {
    clientId: 'your-apple-client-id',
    redirectURI: window.location.origin + window.location.pathname
  },
  X: {
    clientId: 'MVZ6aHMyNmMtSF9mNHVldFR6TV86MTpjaQ',
    redirectURI: window.location.origin + '/auth-callback-X'
  },
  walletConnect: {
    projectId: walletConnectProjectId
  },
});

// Universal config
export const universalConfig: any = createConfig('universal', {
  projectAccessKey: "<your-project-access-key>",
  defaultTheme: 'dark',
  signIn: {
    projectName: 'Sequence Web SDK Demo',
  },
  appName: 'Sequence Web SDK Demo',
  chainIds: [1],
  defaultChainId: 1,
  walletConnect: {
    projectId: walletConnectProjectId
  }
})

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

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>
);

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.

Install the Web SDK dependencies

npm install @0xsequence/connect @0xsequence/hooks wagmi ethers viem 0xsequence @tanstack/react-query
# or
pnpm install @0xsequence/connect @0xsequence/hooks wagmi ethers viem 0xsequence @tanstack/react-query
# or
yarn add @0xsequence/connect @0xsequence/hooks wagmi ethers viem 0xsequence @tanstack/react-query

Setup NextJS Config

For compatibility reasons with wagmi and @walletconnect packages, we need to add the following to our next.config.js file:

// Path: next.config.js
const nextConfig = {
  webpack: (config) => {
    config.externals.push("pino-pretty", "lokijs", "encoding");
    return config;
  },
};

This will get rid of the warnings related to pino-pretty.

Create a Config

Next, create the configuration.

If you want to allow WalletConnect you will also need a walletConnectProjectId.
To setup Google Login follow the Google Configuration for Embedded Wallet.
To setup Apple Login follow the Apple Configuration for Embedded Wallet.
To setup X (Twitter) Login follow the X (Twitter) Configuration for Embedded Wallet.
To setup Gues Mode follow the Guest Mode Configuration for Embedded Wallet.

[config.ts]

import { createConfig } from "@0xsequence/connect";

// Waas config
export const waasConfig: any = createConfig('waas', {
  projectAccessKey: "<your-project-access-key>",
  defaultTheme: 'dark',
  signIn: {
    projectName: 'Sequence Web SDK Demo',
  },
  appName: 'Sequence Web SDK Demo',
  chainIds: [1],
  defaultChainId: 1,
  waasConfigKey: 'waas-config-key',
  guest: true,
  email: true,
  google: {
    clientId 'your-google-client-id'
  },
  apple: {
    clientId: 'your-apple-client-id',
    redirectURI: window.location.origin + window.location.pathname
  },
  X: {
    clientId: 'MVZ6aHMyNmMtSF9mNHVldFR6TV86MTpjaQ',
    redirectURI: window.location.origin + '/auth-callback-X'
  },
  walletConnect: {
    projectId: walletConnectProjectId
  },
});

// Universal config
export const universalConfig: any = createConfig('universal', {
  projectAccessKey: "<your-project-access-key>",
  defaultTheme: 'dark',
  signIn: {
    projectName: 'Sequence Web SDK Demo',
  },
  appName: 'Sequence Web SDK Demo',
  chainIds: [1],
  defaultChainId: 1,
  walletConnect: {
    projectId: walletConnectProjectId
  }
})

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

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;

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>
  );
}

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
