Frequently Asked Questions

What is a hardware / cold wallet, and why do I need one?

A hardware wallet is a physical device that stores private keys offline. It helps protect crypto assets from online threats such as hackers and malware, providing stronger long-term security than software wallets.

What’s the difference between a hot wallet and a cold wallet?

A hot wallet stays connected to the internet and is more exposed to remote attacks. Solum stays air-gapped: keys never leave the device, and signing happens via QR — no USB data, Bluetooth, Wi‑Fi, or NFC.

How does Solum differ from USB hardware wallets?

Many devices rely on USB or Bluetooth channels to a potentially compromised computer. Solum removes that channel entirely. You verify amounts and addresses on a large touchscreen, then broadcast from your phone or laptop.

Can I recover funds if I lose the device?

Yes — if you securely backed up your BIP39 seed (ideally on steel). Restore on a new Solum or any BIP39-compatible wallet. Without the seed, funds cannot be recovered.

Is firmware open source?

Yes. Bootloader, cryptographic stack, and UI source are published. Verify release hashes before flashing. Don’t trust — verify.

Average Rating: 5/5 based on community reviews

Fully air-gapped, QR-only, big touchscreen — finally a cold wallet that feels like a modern device, not a calculator.

Athena · Rating 5/5

Fingerprint + open source + MetaMask flow is seamless. I will never go back to a two-button hardware wallet.

Rearden · Rating 5/5

Integrations with Rabby and Sparrow are clean. Every contract detail shows on the screen before I sign.
