Unboxing & First Setup

Step-by-step
Unboxing Checklist

Verify tamper-evidence seals, inspect packaging for signs of previous opening, and confirm model number on the box. Genuine devices usually contain the hardware, cable, recovery card, quickstart leaflet, and a serial number sticker.

First Boot

Connect the device to your computer using the supplied cable. Do not reuse cables found in public or from unknown sources. The device should boot to a secure, hardware-internal UI; modern Trezór models show a unique seed creation screen and ask for firmware initialization.

Firmware & Authenticity

Always check the firmware hash and authenticity prompt on the device screen. Trezor (and reputable vendors) publish firmware verification instructions. If the device prompts for a firmware update during setup, prefer to update via the official interface.

Create a PIN

Create a strong, memorable PIN using the device’s randomization. Avoid short numeric sequences and never store the PIN digitally. The device will scramble the keypad on-screen to prevent shoulder-surfing attacks.

Generate & Record Recovery Phrase

Write down the recovery seed exactly as shown on the device. Use the provided recovery card or a metal backup solution. NEVER store the seed on a cloud drive, photo library, or note-taking app.

Backup Best Practices

Create at least two geographically separated backups or a single robust metal backup in a secure place. Consider multisig or split-seed strategies for high-value holdings (consult a security professional for advanced setups).

Security Fundamentals

Principles
Private Keys

Private keys should never leave the hardware device. Trezor signs transactions locally and only shares signed transaction data to broadcast—your secret stays inside the device's secure element.

Seed Confidentiality

Your 12/24-word recovery seed is the single source of truth. Anyone with access to it can recreate your wallet. Treat it like cash—physical and confidential.

Supply Chain Attacks

Buy directly from the vendor or trusted resellers. Avoid second-hand devices unless you’ve factory-reset and reinstalled firmware from the manufacturer’s official source.

Phishing & Social Engineering

Authenticate official websites and extensions. Bookmark the genuine Trezor web page and do not click links that arrive unrequested via email. Verify URLs and certificate chains when in doubt.

Physical Security

Secure devices with a safe, safe-deposit box, or locked drawer. For enterprise-level holdings, multi-location cold storage and tamper-evident containers are recommended.

Advanced Setup & Features

Pro tips
Passphrase (25th word)

Passphrase adds an additional layer to your seed: think of it as a password that unlocks a hidden wallet. Use it only if you understand recovery implications — losing the passphrase means losing access to that hidden wallet.

Multisignature (multisig)

Combine multiple hardware devices across different locations or operators to split signing control. Multisig dramatically reduces the risk of single-device compromise.

Hidden Wallets

With passphrases you can create hidden wallets for plausible deniability. Design careful, documented processes for recovery and ensure those entrusted will understand the complexity.

Third-Party Integrations

Trezor integrates with many wallets and DEXs. When connecting to third-party services, always validate transaction details on the device screen before approving.

Electrum / Wasabi / Armada

Use advanced wallets like Electrum for multisig, Wasabi for coinjoin/privacy, and Armada for enterprise controls. Hardware devices act as secure signers in these ecosystems.

Troubleshooting & Recovery

Practical fixes
Lost PIN

If you forget the PIN, perform a factory reset and restore from your recovery seed. This is by design — a reset removes the data stored on the device to prevent brute force theft.

Corrupt Firmware / Bricked Device

Use the official recovery or bootloader tools provided by the vendor. Contact official support channels and follow published recovery procedures — never follow random social media instructions.

Seed Recovery

When restoring, type carefully and verify word order. If the seed card is damaged, consult metal backup options or professional data recovery services for physical damage only.

Transaction Fails

Check nonce, fee levels, and network congestion. For ERC-20 tokens ensure the device and software support the token standard. Verify the exact transaction details on-screen.

Compromise Suspected

Move funds to a new wallet immediately from a secure device if you reasonably suspect compromise. Use a brand-new hardware wallet or secure offline signing environment for the migration.

Comparisons: Trezór vs Other Devices

Context
Trezór vs Ledger

Both are reputable. Trezór focuses on open-source firmware and transparency; Ledger uses a secure element with a closed-source component. Choose based on trust model and feature preferences.

Trezór vs Coldcard

Coldcard emphasizes air-gapped deployment and advanced Bitcoin-focused features. Trezór offers broader coin support and a polished UX for general users.

Custodial vs Self-Custody

Custodial services manage private keys for you (convenient but risk of counterparty failure). Hardware wallets like Trezór enable self-custody, giving full control and responsibility.

Best Practices — Checklist

Do these
Buy from trusted sources

Always purchase directly from the official website or verified resellers to avoid tampered devices.

Keep seed offline

Never photograph or upload your recovery phrase. Use metal backups for fire/water protection.

Test small transfers

Before sending large amounts, do a small test transaction to verify everything works end-to-end.

Use anti-phishing steps

Bookmark official sites, verify DNS and certificates, and consider DNSSEC-capable resolvers for extra caution.

Practice recovery

Rehearse the recovery process on a new device with a throwaway seed or testnet funds to ensure you understand the steps and can do them under stress.

Deep Dive — Cryptography & Wallet Design

Technical
How keys are derived

Hierarchical Deterministic wallets (BIP32/BIP39/BIP44) derive many addresses from a single seed using deterministic paths. A single backup of the seed can restore all derived addresses following the same derivation path.

BIP39 recovery seeds

BIP39 seeds are human-readable word lists, converted into binary entropy. They are resilient but must be correctly recorded and used with the right derivation path and passphrase if applicable.

Transaction signing

When you build a transaction in a wallet, the unsigned payload is sent to the hardware device. The device verifies the transaction’s outputs and signs with the private key only if the user confirms the data shown on the screen.

Privacy note

Hardware wallets help with security but do not fully protect metadata about addresses or transactions. Use privacy-enhancing tools (coinjoin, mixers, Tor, VPNs) to reduce address correlation risks when necessary.

FAQ — Common Questions

Answers
Can I recover without the device?

Yes — if you have your recovery seed, you can restore on another compatible hardware wallet or a software wallet that supports your seed type and derivation path.

Is passphrase required?

No — passphrase is optional. It significantly increases security and complexity. Use it only if you can secure and remember the passphrase reliably.

What if my seed is stolen?

If your seed is compromised, move funds immediately to a new seed/wallet. Ideally, set up a new device offline and transfer funds using a secure, uncompromised environment.

Does firmware update erase my seed?

Typically no — firmware updates preserve device settings and seed as long as you use the official update channel. Always follow official update instructions and ensure backups exist before major changes.

Glossary — Useful Terms

Reference
Seed / Recovery Phrase

A sequence of words representing your wallet’s secret key data. Store safely and redundantly.

Private Key

The secret number that controls funds. Never share it.

Public Key

Derived from the private key and used to derive addresses that others can send funds to.

Derivation Path

The hierarchical path used to derive addresses from the seed (e.g., m/44'/0'/0'/0).

PSBT

Partially Signed Bitcoin Transaction — a format for offline signing workflows and multisig coordination.

Wrap-up & Next Steps

Action
Immediate next steps

1) Verify your device and firmware. 2) Generate and protect your recovery seed. 3) Practice a restore on a secondary device. 4) Store backups in different secure locations.

Long-term security

Review your backup plan yearly, keep device firmware updated, and adopt institutional practices for multi-user custody if relevant.
