ConnectButton

The ConnectButton is the primary component for wallet connections in LunoKit. It handles the entire wallet connection flow and adapts its appearance based on the connection state.

Basic Usage

import { LunoKitProvider, ConnectButton } from '@luno-kit/ui'
import { createConfig, polkadot, polkadotjs } from '@luno-kit/react'
import '@luno-kit/ui/styles.css'

const config = createConfig({
  appName: 'My Polkadot App',
  chains: [polkadot],
  connectors: [polkadotjs()],
})

function App() {
  return (
    <LunoKitProvider config={config}>
      <ConnectButton />
    </LunoKitProvider>
  )
}

States

The ConnectButton automatically adapts to different connection states:

Disconnected State

When no wallet is connected, shows a simple connect button:

<ConnectButton label="Connect Wallet" />

Connected State

When connected, displays account info, balance, and chain selector:

• Account section: Shows wallet icon, formatted address
• Balance section: Displays transferable balance (optional)
• Chain section: Shows current chain with icon (optional)

Integration with Hooks

The ConnectButton works seamlessly with LunoKit hooks:

import { useAccount, useConnect } from '@luno-kit/react'
import type { ConnectionStatus } from '@luno-kit/react'

function CustomComponent() {
  const { account } = useAccount()
  const { status } = useConnect()
  
  return (
    <div>
      <ConnectButton />
      {status === ConnectionStatus.Connected && (
        <p>Connected as {account?.name}</p>
      )}
    </div>
  )
}
