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.

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, 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.

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.

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

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.

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

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

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
