4. Select Backup Type: Trezor Suite supports 12-word or 24-word BIP-39 seeds or 20-word SLIP-39 Shamir Backup for advanced users. For compatibility with other wallets, opt for 12 or 24-word seeds.
5. Write Down the Seed Phrase: The device displays the recovery seed (12, 20, or 24 words). Write it down on the provided seed card and store it securely offline. Never store it digitally or share it.
6. Set a PIN: Choose a strong PIN (up to 9 digits for Model One, or more complex for Model T and Safe models). Confirm the PIN on the device to prevent keylogger exposure.

Step 4: Access Trezor Suite

After setup, select "Access Suite" to enter the dashboard. You can name your device for easier identification if you own multiple Trezors. Activate desired coins (Bitcoin is enabled by default) and proceed to manage your assets.

Security Features of Trezor Suite

Trezor Suite prioritizes security, leveraging the offline nature of Trezor hardware wallets. Key security features include:

Offline Private Key Storage

Trezor devices store private keys offline, protecting them from online threats like hacking or malware. Transactions are signed on the device and verified on its screen, ensuring no sensitive data is exposed to the connected computer or phone.

Passphrase and Hidden Wallets

A passphrase adds an extra layer of security to your wallet backup, creating unique “hidden wallets.” Each passphrase (up to 50 ASCII characters, case-sensitive) generates a distinct wallet. For example, entering “MySecret123” creates a different wallet than “mysecret123.” Passphrases are not stored on the device, so they must be memorized or securely stored offline, separate from the seed phrase. If lost, the associated wallet becomes inaccessible. To enable passphrases:

1. Go to Device Settings in Trezor Suite.
2. Toggle the passphrase feature on.
3. Enter the passphrase on the device (preferred for Model T and Safe models) or via a trusted computer’s keyboard.

Shamir Backup (SLIP-39)

Available on Trezor Model T, Safe 3, and Safe 5, Shamir Backup (SLIP-39) splits the recovery seed into multiple shares (e.g., 20-word phrases). Users can set a threshold (e.g., 3 out of 5 shares) to recover the wallet, enhancing security and redundancy. Unlike BIP-39 (12/24 words), SLIP-39 is less widely supported but offers advanced protection against theft or loss. Store shares in separate, secure locations.

Entropy Check

Introduced in the February 2025 update, the entropy check ensures wallets are generated by authentic Trezor devices, reducing the risk of counterfeits. This feature is accessible via the settings menu and is recommended for new setups.

Address Verification

Trezor Suite guides users through secure address verification to prevent address poisoning attacks. When receiving crypto, confirm the address on the Trezor device’s screen to ensure it matches the intended destination.

Discreet Mode

For added privacy, enable Discreet Mode to hide sensitive information (e.g., balances) from onlookers. This is particularly useful in public settings.

Transaction Security

Trezor Suite supports Replace-By-Fee (RBF) for canceling pending Bitcoin transactions and filters suspicious transactions on supported networks. The redesigned send confirmation process (February 2025 update) enhances security by requiring on-device verification.

Using Trezor Suite for Crypto Management

Sending and Receiving Crypto

• Receiving: Generate a receive address in Trezor Suite, confirm it on the device, and share it with the sender. For XRP, ensure the destination tag is correctly set.
• Sending: Enter the recipient’s address, amount, and transaction fee. Confirm the details on the Trezor device to sign the transaction securely.

Buying, Selling, and Swapping

Trezor Suite integrates with Invity for buying, selling, and swapping cryptocurrencies. The March 2025 update introduced over-the-counter (OTC) trading for high-value transactions and 1inch Fusion for cheaper DEX swaps. To trade:

1. Navigate to the Trade section.
2. Select Buy, Sell, or Swap.
3. Choose a provider, confirm the transaction details, and verify on the device.

Staking

Stake assets like Solana, Ethereum, or Cardano to earn rewards. The March 2025 update added Solana staking directly in Trezor Suite. Navigate to the Stake feature, delegate your assets, and monitor rewards in the dashboard.

Portfolio Tracking

The dashboard displays your portfolio’s total value, individual asset balances, and transaction history. Export transaction data in .csv, .pdf, or .json formats for record-keeping.

View-Only Mode

Enable view-only mode to check balances without connecting the Trezor device. This is ideal for mobile use via Trezor Suite Lite (Android) or web app (iOS, view-only).

Advanced Features

Multi-Share Backup

For SLIP-39 users, create multiple backup shares to distribute risk. For example, split a 20-word seed into five shares, requiring three to recover the wallet. This is ideal for users seeking advanced security.

WalletConnect

Available via Experimental Features (April 2025 update), WalletConnect allows Trezor Suite to connect to decentralized apps (dApps) for DeFi interactions.

Third-Party Wallet Compatibility

Trezor Suite supports third-party wallets like MetaMask, Rabby, and Exodus. Import your Trezor seed into these wallets (using the 12/24-word BIP-39 seed) for additional functionality, but avoid entering the seed on untrusted platforms.

Custom Settings

Customize Trezor Suite via the settings menu:

• Language: Choose from multiple languages or match your system’s language.
• Fiat Currency: Display balances in your preferred fiat currency.
• Bitcoin Units: Toggle between BTC and satoshis.
• Color Scheme: Select light, dark, or system-default themes.
• Address Display: Choose continuous or spaced formats for easier verification.

Updates and Maintenance

Trezor Suite receives regular updates to enhance functionality and security. The April 2025 update (version 25.4.3) introduced faster loading in view-only mode, suspicious transaction filtering, and an improved DCA (Dollar-Cost Averaging) page. To update:

1. Open Trezor Suite and follow the on-screen prompt to download the latest version.
2. Alternatively, manually download from trezor.io and verify the signature.
3. Join the Early Access Program for beta features, accessible via Application Settings.

Always verify firmware and software updates to avoid compromised versions. Use TrezorCTL for advanced firmware verification if needed.

Troubleshooting Common Issues

• Device Not Recognized: Ensure Trezor Bridge is installed and the USB connection is secure. Check for firmware updates.
• Passphrase Issues: Verify the passphrase for case sensitivity and typos. If lost, the associated wallet is inaccessible unless backed up.
• Seed Entry Errors: For words with double letters (e.g., “cattle”), use the multi-tap approach on the device or auto-fill after typing the first few letters.
• Transaction Delays: Check network congestion or use RBF to cancel pending Bitcoin transactions.
• Support: Contact Trezor Support via https://trezor.io/support. Never share your seed phrase or passphrase.

Security Best Practices

1. Store Seed and Passphrase Securely: Keep your recovery seed and passphrase offline, ideally in a fireproof safe or on a Trezor Keep Metal.
2. Avoid Digital Storage: Never store your seed or passphrase on a computer, phone, or password manager.
3. Use a Strong Passphrase: Combine letters, numbers, and symbols for maximum security.
4. Regularly Update Firmware and Software: Stay protected with the latest security patches.
5. Beware of Phishing: Only download Trezor Suite from trezor.io and verify all addresses on the device.

Comparing 12, 20, and 24-Word Backups

• 12-Word (BIP-39): Default for Trezor Model T and Safe models, offering 128 bits of entropy. Sufficient for most users and compatible with other wallets.
• 20-Word (SLIP-39): Used for Shamir Backup on Model T, Safe 3, and Safe 5. Provides advanced security by splitting the seed into shares but has limited third-party support.
• 24-Word (BIP-39): Default for Trezor Model One due to computer-based recovery. Offers 256 bits of entropy but is less practical for modern devices with on-device recovery.

For maximum compatibility, use 12 or 24-word seeds unless you specifically need Shamir Backup’s features.
