Hardware wallets give you a dedicated, tamper-resistant environment for private keys. When you isolate keys inside a hardware device, malware on your computer or mobile device cannot easily exfiltrate them. This single principle — separation of signing from connected environments — is the foundation of safe crypto custody.

This checklist is intentionally minimal so you can follow it in order without skipping essential safety steps. Each item links to a deep-dive section with rationale and next-steps.
When you receive a device, do a short physical checklist: check tamper seals, serial numbers (if exposed), and packaging. If the packaging looks resealed, contact the vendor. For higher assurance, verify the device firmware fingerprint or signature as described in the vendor's documentation.
Power the device on and follow the on-screen prompts. Choose to generate a new wallet (entropy is created by the device). Create a PIN — this protects the device against casual access. Important: the PIN is not the same as the recovery phrase and cannot be used to reconstruct keys if lost.
Only use the official companion software. Install from the vendor's website and verify the download (checksums or signatures) if available. When the app prompts to connect the device, allow the pairing and verify that the device screen shows the same details as the app (device model, fingerprint) before proceeding.
Recovery is the most crucial part of long-term custody. The seed phrase (also called the recovery phrase) encodes your private key material — protect it like a financial heirloom.
Design a recovery plan that balances risk and complexity. Example:
Device-root — the immutable hardware identity in the device used to verify firmware and provenance.
Flowproof — processes designed to reduce human error, using checklists, rehearsals, and role assignments.
Key-fabric — a metaphor for the intentionally distributed backup network that balances access and resilience.
Security for a hardware wallet rests on three pillars: device integrity, recovery secrecy, and operational discipline.
Map threats relative to your holdings and exposure. For small retail holdings, basic physical security plus a single durable backup may suffice. For larger or institutional holdings, plan for multisig and geographically distributed backups.
Multisig requires multiple keys to sign a transaction, increasing resilience. Use multisig when the value you're protecting justifies the added complexity.
Prepare the unsigned transaction on an online machine, move it to the air-gapped environment via QR or SD card, sign on the device, then broadcast from an online machine. This keeps signing isolated from direct network exposure.
Create role-based playbooks: operators (day-to-day signers), stewards (heavy-lift maintainers), and emergency contacts. Each role should have clear, limited responsibilities and tested recovery drills.
Device won't power: try a known-good cable and port; if still unresponsive, contact vendor support and do not attempt third-party firmware unless you understand the risk.
Forgot PIN: most devices wipe after repeated incorrect attempts — restore from your recovery phrase on a new device.
Lost recovery: if you still have device access, create a new wallet and transfer funds; otherwise funds could be irrecoverable.
Private key: secret data used to sign transactions.
Public key / address: shareable identifier to receive funds.
Seed / recovery phrase: mnemonic words encoding key material.
Device-root: hardware identity and trust anchor inside a device.
