Download BitHarbour on any device, select "Restore Wallet," and enter your 12 or 24-word seed phrase (and passphrase if you set one). Your wallet and all funds will be restored instantly. Never share your seed phrase with anyone — including BitHarbour support.

Most transactions confirm within 10-60 minutes depending on network congestion and the fee you select. BitHarbour automatically recommends optimal fees. For instant payments, use the built-in Lightning Network integration which settles in seconds with near-zero fees.

Yes! BitHarbour integrates with Ledger (Nano S Plus, Nano X, Stax), Trezor (Model T, Safe 3, Safe 5), Coldcard (Mk4, Q), and Foundation Passport. Connect your hardware wallet via USB or Bluetooth for air-gapped transaction signing.

BitHarbour is available on iOS, Android, macOS, Windows, and Linux. Your wallet syncs seamlessly across all your devices via encrypted cloud backup. The web interface provides full access from any modern browser.

BitHarbour itself is free to use for basic wallet functionality. You only pay standard Bitcoin network transaction fees (which go to miners, not us). Premium features like advanced multi-sig coordination and inheritance planning are available with BitHarbour Pro.

Never. BitHarbour is fully non-custodial — we don't hold, see, or have any access to your private keys or funds. Your Bitcoin is yours alone. Not even a court order could compel us to access your wallet because we simply cannot.
