Welcome — why a hardware device?

Hardware crypto devices keep your private keys offline and under your control. Unlike exchanges and software wallets, a dedicated hardware device isolates signing operations in a tamper-resistant environment — which dramatically reduces the risk of theft from online attacks. This page walks you through setting up your device safely and confidently.

Quick note: This is a friendly how-to and not affiliated with any brand. Always verify downloads and follow official manufacturer instructions for critical operations.

Unboxing & first-look

When you receive your device, inspect the packaging for tamper-evidence seals and genuine branding. Inside you should typically find the device itself, a USB cable, a recovery card or sheet, and quick-start documentation. Keep the recovery material completely offline — it’s the single most important copy of your funds' recovery information.

Box checklist

  • Device and USB cable
  • Recovery card(s)
  • Quick start guide
  • Tamper seal (if required)

Room setup tip

Set aside a quiet, private surface. Avoid taking photos of recovery words or entering them on any connected devices.

Step-by-step: first-time setup

1

Download the official companion app

Grab the official Suite or app only from the manufacturer’s site. Verify the URL and compare checksums if provided. Prefer desktop applications for firmware updates and initial setup, and always avoid third-party downloads unless explicitly supported.

2

Connect the device & initialize

Plug in using the supplied cable. The companion app will guide you through initializing a new device or recovering an existing one. Choose to create a new seed only if you are certain the device is new and untampered.

3

Create a secure PIN

Choose a PIN that’s easy for you to remember but hard for others to guess. The device will lock after several incorrect attempts; if locked, restoring requires your recovery seed — so protect both the device and the seed.

4

Write down your recovery seed — offline

Write the words on the provided recovery card (or a steel backup for long-term storage). Never store the seed on a phone, cloud, or photo. Consider multiple offline copies in different secure locations.

5

Optional: enable passphrase

A passphrase acts as an additional '25th' word — it creates a separate hidden wallet. It's powerful but can be dangerous if you lose the passphrase. Only use it if you fully understand the tradeoffs.

6

Update firmware when prompted

Firmware updates patch vulnerabilities and add features. Follow the companion app’s instructions precisely — do not interrupt the update. Validate update sources and release notes before applying.

Daily workflows — send, receive, and verify

Using your device is a two-stage process: initiate transactions on your computer or phone, then confirm and sign them on the physical device. This ensures that even if your computer is compromised, attackers cannot sign transactions without the device physically approving them.

Sending funds

  • Open the account for the currency you want to send.
  • Paste the recipient address — double-check characters or scan a QR code.
  • Review amounts, network fees, and addresses on the device display before confirming.

Receiving funds

Generate a receive address in the companion app and verify the address on your device screen. Only share addresses after confirming them on-device.

Backup strategies & safety

Consider using a steel backup for your recovery seed for long-term resilience against fire and water. For very large holdings, consider geographically separating multiple encrypted copies or enlisting a trusted custodian with legal protections.

Important: Never share your seed, passphrase, or PIN with anyone — no legitimate support will ever ask for them.

Advanced tips for power users

  • Use coin-control and custom fees for precise on-chain management.
  • Integrate with privacy tools (e.g., coin-mixers) only after understanding legal and security implications.
  • Consider a dedicated, clean computer for high-value operations.
  • For multi-user setups, explore multisig configurations to split signing power across devices or people.

Quick FAQ

Q: What if I lose my device?

A: Use your recovery seed to restore on a new device. If your seed is lost too, funds are unrecoverable.

Q: Can I use multiple devices?

A: Yes. You can recover the same seed on another device or create additional devices with separate seeds for compartmentalization.
