Usage

import { useSignInEmail } from '@0xsequence/connect'

      <h2>User Information</h2>
      {email ? (

          <p>Connected with email: {email}</p>
        </div>
      ) : (
        <p>No email associated with connected wallet</p>
      )}
    </div>
  )
}

Return Type

string | null

The hook returns:

• A string containing the email address when a wallet is connected and has an associated email
• null when:
  • No wallet is connected
  • The connected wallet has no associated email
  • The wallet has been disconnected

State Management

The hook manages the email state by:

1. Monitoring the wallet connection status
2. Retrieving the stored email when a wallet connects
3. Clearing the email when the wallet disconnects
4. Persisting the email in local storage using the WaasSignInEmail key

Notes

This hook is designed to work with both:

• Sequence WaaS (Wallet-as-a-Service) wallets
• Universal wallet types

The hook integrates with Sequence’s storage system to maintain email persistence across sessions while ensuring proper cleanup when wallets are disconnected.
