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

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 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/design-system/styles.css'

const projectAccessKey = 'xyz'

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

const transports = {}

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

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

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

const queryClient = new QueryClient()

function App() {
  return (
    <WagmiProvider config={config}>
      <QueryClientProvider client={queryClient}>
        <KitProvider>
          <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, or set it to something else.

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>
