Sequence Kit 🧰

Sequence Kit 🧰 is a library enabling developers to easily integrate web3 wallets in their app. It is based on wagmi and supports all wagmi features.

• Connect via social logins eg: facebook, google, discord, etc...! 🔐🪪
• Connect to popular web3 wallets eg: walletConnect, metamask ! 🦊 ⛓️
• Full-fledged embedded wallet for coins and collectibles 👛 🖼️ 🪙

Quick Start

Installing the Library

@0xsequence/kit is the core package. Any extra modules require this package to be installed first. To install this package:

npm install @0xsequence/kit wagmi [email protected] viem 0xsequence @tanstack/react-query
# or
pnpm install @0xsequence/kit wagmi [email protected] viem 0xsequence @tanstack/react-query
# or
yarn add @0xsequence/kit wagmi [email protected] viem 0xsequence @tanstack/react-query

Setting up the Library

The 'easy' way

• createConfig(walletType, options) method is used to create your initial config and prepare sensible defaults that can be overridden

walletType is either 'waas' or 'universal'

interface CreateConfigOptions {
  appName: string
  projectAccessKey: string
  chainIds?: number[]
  defaultChainId?: number
  disableAnalytics?: boolean
  defaultTheme?: Theme
  position?: ModalPosition
  signIn?: {
    logoUrl?: string
    projectName?: string
    useMock?: boolean
  }
  displayedAssets?: Array<{
    contractAddress: string
    chainId: number
  }>
  ethAuth?: EthAuthSettings
  isDev?: boolean

  wagmiConfig?: WagmiConfig // optional wagmiConfig overrides

  waasConfigKey?: string
  enableConfirmationModal?: boolean

  walletConnect?:
    | false
    | {
        projectId: string
      }

  google?:
    | false
    | {
        clientId: string
      }

  apple?:
    | false
    | {
        clientId: string
        redirectURI: string
      }

  email?:
    | boolean
    | {
        legacyEmailAuth?: boolean
      }
}

import { SequenceKit, createConfig } from '@0xsequence/kit'

import Content from './components/Content'

const config = createConfig('waas', {
  projectAccessKey: '<your-project-access-key>',
  chainIds: [1, 137]
  defaultChainId: 1
  appName: 'Demo Dapp',
  waasConfigKey: '<your-waas-config-key>',

  google: {
    clientId: '<your-google-client-id>'
  },

  apple: {
    clientId: '<your-apple-client-id>',
    redirectUrl: '...'
  },

  walletConnect: {
    projectId: '<your-wallet-connect-id>'
  }
})

function App() {
  return (
    <SequenceKit config={config}>
      <Content />
    </SequenceKit>
  )
}

Need more customization?

React apps must be wrapped by a Wagmi client and the KitWalletProvider components. It is important that the Wagmi wrapper comes before the Sequence Kit wrapper.

import Content from './components/Content'
import { KitProvider, getDefaultConnectors, getDefaultChains } from '@0xsequence/kit'
import { QueryClient, QueryClientProvider } from '@tanstack/react-query'
import { createConfig, http, WagmiProvider } from 'wagmi'
import { mainnet, polygon, Chain } from 'wagmi/chains'

import '@0xsequence/kit/styles.css'

const projectAccessKey = '<your-project-access-key>'

const chains = getDefaultChains(/* optional array of chain ids to filter */)

const transports = {}

chains.forEach(chain => {
  transports[chain.id] = http()
})

// Universal wallet configuration
const connectors = getDefaultConnectors('universal', {
  projectAccessKey,
  appName: 'Demo Dapp',
  defaultChainId: 137,

  walletConnect: {
    projectId: '<your-wallet-connect-id>'
  }
})

/* 
  const connectors = getDefaultWaasConnectors('{
    projectAccessKey,
    defaultChainId: 137,
    appName: 'Demo Dapp',

    waasConfigKey: '<your-waas-config-key>',
    
    google: {
      clientId
    },

    apple: {
      clientId,
      redirectUrl
    },

    walletConnect: {
      projectId: '<your-wallet-connect-id>'
    }
  })
  */

const wagmiConfig = createConfig({
  chains,
  transports,
  connectors
})

const kitConfig = {
  projectAccessKey: '...'
}

const queryClient = new QueryClient()

function App() {
  return (
    <WagmiProvider config={wagmiConfig}>
      <QueryClientProvider client={queryClient}>
        <KitProvider config={kitConfig}>
          <Content />
        </KitProvider>
      </QueryClientProvider>
    </WagmiProvider>
  )
}

Opening the Sign in Modal

Wallet selection is done through a modal which can be called programmatically.

import { useOpenConnectModal } from '@0xsequence/kit'
import { useDisconnect, useAccount } from 'wagmi'

const MyReactComponent = () => {
  const { setOpenConnectModal } = useOpenConnectModal()

  const { isConnected } = useAccount()

  const onClick = () => {
    setOpenConnectModal(true)
  }

  return <>{!isConnected && <button onClick={onClick}>Sign in</button>}</>
}

Hooks

useOpenConnectModal

Use the useOpenConnectModal to change to open or close the connection modal.

import { useOpenConnectModal } from '@0xsequence/kit'
// ...
const { setOpenConnectModal } = useOpenConnectModal()
setOpenConnectModal(true)

useTheme

Use the useTheme hook to get information about the current theme, such as light or dark.

import { useTheme } from '@0xsequence/kit'
const { theme, setTheme } = useTheme()

setTheme('light')

Customization

The KitProvider wrapper can accept an optional config object.

The settings are described in more detailed in the Sequence Kit documentation.

  const kitConfig =  {
    defaultTheme: 'light',
    position: 'top-left',
    signIn: {
      logoUrl: 'https://logo-dark-mode.svg',
      projectName: 'my app',
    };
    // limits the digital assets displayed on the assets summary screen
    displayedAssets: [
      {
        contractAddress: ethers.ZeroAddress,
        chainId: 137,
      },
      {
        contractAddress: '0x631998e91476da5b870d741192fc5cbc55f5a52e',
        chainId: 137
      }
    ],
  }

  <KitProvider config={kitConfig}>
    <App />
  <KitProvider>

Local Development

The React example can be used to test the library locally.

1. Replace the kit dependencies to the ones of the workspace in order to use hot reload.:

"@0xsequence/kit": "workspace:*",
"@0xsequence/kit-checkout": "workspace:*",
"@0xsequence/kit-wallet": "workspace:*",

2. pnpm install
3. From the root folder, run pnpm build to build the packages OR optionally run pnpm dev in a separate terminal to develop in watch mode.
4. From the root folder, run pnpm dev:react or pnpm dev:next to run the examples.

What to do next?

Now that the core package is installed, you can install the embedded wallet or take a look at the checkout.
