A hardware wallet is safest when you authenticate the device before use, install only vendor-signed firmware, choose a strong PIN, verify every transaction on the wallet screen, and create and protect a recovery phrase yourself. A box seal alone cannot prove that a wallet is genuine.
What this checklist protects against
Hardware wallets keep private keys in a dedicated device instead of exposing them directly to a general-purpose computer or phone. That design reduces risk, but it does not eliminate threats. A counterfeit or previously opened device, altered firmware, a guessed PIN, a fake setup page, or a photographed recovery phrase can still put funds at risk.
Use the checks below as a chain. Supply-chain evidence, firmware authentication, access control, trusted-screen verification and a protected backup each cover a different failure mode. Passing one check does not compensate for skipping another.
Before you open the package
Buy from an authorized channel
Purchase through the wallet maker’s official shop, its documented marketplace storefront or an authorized reseller. Trezor specifically warns: “Never buy a Trezor from an unauthorized third party, as you can never tell who may have had access to it before you.” Avoid used devices, auction listings and marketplace sellers whose authorization you cannot confirm.

Keep the order confirmation, seller details and delivery date. Photograph the unopened package from all sides before breaking any seal. These records help you document a tampered shipment and make it easier to obtain support or a replacement.
Inspect the packaging and seals
Look for torn cardboard, re-glued edges, mismatched labels, scratches around the device, opened accessories or seals that do not sit flat. Ledger says a damaged tamper-proof seal or any sign of tampering is a reason not to use the device.
Seal designs are model-specific. Trezor documents holographic seals, including a seal covering the USB-C port on the Trezor Safe 7. Confirm the seal against the instructions for your exact model rather than relying on a photograph from another product generation.
A seal is only one signal. A capable attacker may replace packaging, and an intact seal does not prove that firmware, the device electronics or the seller’s supply chain are trustworthy. Continue with the software and on-device checks before creating or importing a wallet.
Verify the device and firmware before adding funds
Start with a clean-device expectation
Connect the wallet only to the manufacturer’s official application downloaded from the vendor’s normal distribution channel. Do not follow setup links from an unsolicited email, a QR code on the box or a search advertisement that you cannot validate.

Trezor states that its devices are distributed without firmware installed. During setup, the application checks whether firmware is already present. A device that arrives with a wallet, a recovery phrase or unexplained firmware already configured is not a normal clean setup; stop and contact the vendor.
Check the firmware signature
Trezor’s bootloader verifies the firmware signature each time the device connects. If the firmware is unofficial, the wallet displays a warning. Do not dismiss that warning, continue to a wallet, or enter a recovery phrase. Disconnect the device and use the vendor’s support process.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Firmware updates should be initiated from the official application and confirmed on the wallet’s own screen. Record the model and firmware version shown after the update. If the application reports a signature, authenticity or installation failure, treat the device as untrusted until the manufacturer resolves it.
Do not let a computer make the security decision
A compromised computer can display a convincing interface while attempting to redirect a transaction or collect a phrase. The computer’s job is to provide data to the wallet; the wallet’s trusted display must make the final decision about what is signed.
Choose and protect a PIN
Create an unpredictable PIN
Use the wallet’s PIN setup screen to generate a random, difficult-to-guess 4–6 digit PIN, following the range supported by your model. Do not use a birthday, year, address number, repeating digits, a keypad pattern or any number reused on another account. Ledger’s guidance specifically recommends a random 4–6 digit PIN and avoiding dates or personal numbers.

Never type the PIN into a computer or save it in a password manager that synchronizes to the cloud unless the manufacturer explicitly designs that workflow. Memorize it or keep a private, offline record separate from the recovery phrase.
Understand failed-attempt protections
PIN behavior differs by model. Some wallets enforce attempt limits in hardware or increase a delay after failures; others may reset or wipe data under defined conditions. Read the documentation for your exact model before testing guesses. Trezor documents Secure Element protections and attempt limits on supported devices. Do not deliberately enter wrong PINs to “test” a new wallet.
A PIN protects the device, not the underlying wallet backup. Anyone who obtains the recovery phrase can generally restore the wallet on a compatible device without knowing the PIN.
Verify every transaction on the wallet itself
Check destination, amount and network
Before approving a transaction, compare the destination address, amount, asset and network shown on the wallet’s trusted screen with the request you intended to make. Scroll through the complete address when the device permits it; do not rely on the first or last few characters alone. Confirm network details because an address or token on one network may not be interchangeable with another.
BitBox describes on-device detail verification as a core principle. Treat the computer or phone as potentially compromised: malware can replace a copied address or alter an amount while leaving the desktop interface looking normal.

Reject anything you cannot independently confirm
Cancel if the wallet display is blank, truncated, inconsistent with the application, or asks you to approve an operation you did not initiate. Never approve a “verification,” “refund,” or “support” transaction merely because a message claims it is required to unlock funds.
Generate the recovery phrase during setup
Let the wallet create the backup
Initialize a new wallet on the device and follow its setup flow. Ledger says the phrase is generated by the wallet and is the backup from which private keys are derived. Trezor likewise says setup generates a unique wallet backup.
Write the words in the order displayed, using the supplied card or another durable offline medium. Check every word and its position on the device when the setup process asks you to confirm them. A prewritten phrase, a phrase supplied by a seller, or a device that skips phrase generation is a reason to stop and return it.
Keep the phrase completely offline
Ledger’s warning is unambiguous: “Never ever share your 24-word secret recovery phrase, also known as a seed phrase, in any form, with anyone.” Support staff, exchange employees and wallet applications do not need the phrase to diagnose a normal device problem.
- Do not photograph or scan the words.
- Do not type them into a website, email, chat, password manager or cloud note.
- Do not store them in a file on a phone or computer connected to the internet.
- Do not show them to a person who is helping with setup.
- Store the written backup where unauthorized people cannot see, remove or destroy it.
Anyone who obtains the phrase can usually recreate the wallet and move its assets. The PIN, device and packaging cannot compensate for an exposed phrase.

Plan for loss, damage and phrase exposure
If the device is lost or broken
The wallet can be replaced when the recovery phrase remains private and readable. Obtain a compatible replacement from an authorized channel, initialize the recovery process on the device itself and enter the phrase only when the trusted screen requests it. Verify that the restored accounts and addresses match your records before making a transaction.
If the phrase may have been exposed
Assume the wallet is compromised. As soon as you can use a trusted device, create a new wallet with a newly generated phrase and transfer funds to addresses controlled by that wallet. Do not “confirm” the old phrase on a website, and do not continue using it simply because no funds have moved yet.
If the only copy is destroyed
A wallet cannot reconstruct a lost phrase from its PIN or from the device after a reset. If the device still opens, move funds to a newly initialized wallet and create a fresh protected backup before resetting or discarding anything. If neither the device nor a readable backup is available, recovery may be impossible.

A practical setup checklist
- Confirm the seller is an authorized channel and save the order record.
- Photograph the unopened package, then inspect labels, accessories and model-specific seals.
- Stop if the package or tamper-evident seal is damaged.
- Download the manufacturer’s official wallet application without using an unsolicited link.
- Connect the device and confirm it starts in the expected clean state.
- Read the firmware status and signature warning on the wallet and application; stop on any failure.
- Install updates only through the official application and record the resulting version.
- Generate a new wallet on the device and write the recovery phrase offline.
- Complete the device’s phrase-confirmation test and store the backup in a private location.
- Create a random 4–6 digit PIN supported by the model and learn its failed-attempt policy.
- Send a small test transaction only after checking its destination, amount and network on the wallet screen.
- Document where the backup is stored and how a trusted person could access it in an emergency without learning the words during ordinary use.
Stop signs that require a return or reset
- The seller cannot demonstrate authorization, or the package appears previously opened.
- The device arrives with firmware, an account or a recovery phrase already configured.
- The wallet reports unofficial, unverifiable or failed firmware.
- A website, message or support person asks for the recovery phrase or PIN.
- The trusted display differs from the computer or phone, or omits key transaction details.
- You wrote the phrase into a digital file, photographed it or showed it to someone else.
When any of these occurs, disconnect the device, preserve the packaging and contact the manufacturer’s official support channel. If a phrase was exposed, prioritize moving funds to a newly initialized wallet with a newly generated backup rather than trying to repair the old one.
