  • 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.
