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 @0xsequence/kit-connectors wagmi ethers@5.7.2 viem 0xsequence @tanstack/react-query
# or
pnpm install @0xsequence/kit @0xsequence/kit-connectors wagmi ethers@5.7.2 viem 0xsequence @tanstack/react-query
# or
yarn add @0xsequence/kit @0xsequence/kit-connectors wagmi ethers@5.7.2 viem 0xsequence @tanstack/react-query

Setting up the Library

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

const queryClient = new QueryClient() 

function App() {
  const chains = [mainnet, polygon] as [Chain, ...Chain[]]
  
  const projectAccessKey = 'xyz'

  const connectors = getDefaultConnectors({
    walletConnectProjectId: 'wallet-connect-id',
    defaultChainId: 137,
    appName: 'demo app',
    projectAccessKey
  })

  const transports = {}

  chains.forEach(chain => {
    transports[chain.id] = http()
  })
  
  const config = createConfig({
    transports,
    connectors,
    chains
  })

  return (
    <WagmiConfig config={config}>
      <QueryClientProvider client={queryClient}> 
        <KitProvider>
          <MyPage />
        </KitProvider>
      </QueryClientProvider>
    </WagmiConfig>
  );
}

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',
      showEmailInput: true,
      socialAuthOptions: ['google', 'facebook', 'twitch', 'apple'],
      walletAuthOptions: ['sequence', 'metamask', 'wallet-connect', 'coinbase-wallet'],
    };
    // limits the digital assets displayed on the assets summary screen
    displayedAssets: [
      {
        contractAddress: ethers.constants.AddressZero,
        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-connectors": "workspace:*",
"@0xsequence/kit-wallet": "workspace:*",

2. pnpm install
3. From the root folder, run pnpm watch to build the package in watch mode in one console.
4. From the root folder, run pnpm start:react to run the react example in another console.

What to do next?

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