Quick install — Get started (h4)

Step-by-step

  1. Open Firefox and visit the official Mozilla Add-ons page for Phantom (link list below).
  2. Click “Add to Firefox” and approve required permissions.
  3. Create a new wallet or restore from a seed phrase/secret recovery phrase.
  4. Set a strong password and securely record your recovery phrase offline.
  5. Open the extension, connect to a dApp, and confirm the transaction when prompted.
