Installation Steps. Always install via official sources: Chrome Web Store, Edge Add-ons, or Coinbase Wallet site. Confirm publisher and permissions. After installation, enable PIN or mobile pairing.

Recovery & Backup. Record your recovery phrase offline in multiple secure locations. Never store digitally. Consider hardware wallets for additional security.
