How to Set Up a New Trezor Model One Wallet

Initial Physical Connection and Portal Access

1. Plug the Trezor Model One device into a computer using the supplied USB cable.

2. Launch any modern web browser and navigate directly to trezor.io/start.

3. Ensure no third-party extensions or ad blockers interfere with the domain loading process.

4. Wait for the official Trezor interface to load without redirection or certificate warnings.

5. Confirm the URL remains unchanged throughout the setup flow — never enter recovery phrases or PINs on non-official domains.

Wallet Creation and Backup Procedure

1. Select the “Create New Wallet” option on the dashboard.

2. Proceed to the backup generation step only after verifying the device screen displays “Backup your wallet”.

3. Write down all 24 recovery words in exact order on paper — digital storage is strictly prohibited.

4. Double-check spelling, capitalization, and sequence against the device display before proceeding.

5. Store the written recovery sheet in a physically secure, fire-resistant, and humidity-controlled location.

PIN Code Configuration and Device Finalization

1. Enter a numeric PIN of at least four digits; longer sequences increase resistance to brute-force attempts.

2. Confirm the PIN by re-entering it on the Trezor device screen — not via keyboard input.

3. Observe the device’s tactile feedback during each button press to avoid accidental misentries.

4. Avoid using predictable patterns such as birthdays, repeated digits, or sequential numbers.

5. Complete final firmware verification before exiting the setup wizard.

Account Initialization and Asset Visibility

1. After setup, the default Bitcoin account appears under “Account #1” in the Trezor Suite interface.

2. Click the dropdown arrow beside the BTC balance to reveal supported cryptocurrencies including Ethereum, Litecoin, and Dash.

3. For Ethereum-based tokens, access MyEtherWallet integration through the dedicated “Go to MyEtherWallet” button.

4. Verify that each displayed address matches the one shown on the Trezor device screen before initiating any transaction.

5. Never confirm unsigned transactions — every outgoing transfer must be manually approved on the hardware display.

Security Protocol Enforcement

1. Disable automatic firmware updates unless initiated manually through trezor.io/manager.

2. Refuse all unsolicited firmware update prompts from third-party applications or email links.

3. Reject connection requests from unrecognized Bluetooth or NFC sources — Trezor Model One does not support either protocol.

4. Use only original USB cables; counterfeit cables may introduce data leakage pathways.

5. Perform periodic integrity checks by verifying firmware version against the official changelog published at trezor.io/firmware.

Frequently Asked Questions

Q: Can I reuse my Trezor Model One recovery phrase on another hardware wallet?A: Yes, but only if the target device implements BIP-39 and BIP-44 standards identically — Ledger devices accept Trezor phrases, while KeepKey and Coldcard do so with minor configuration adjustments.

Q: What happens if I enter the wrong PIN three times?A: The device triggers a full wipe — all private keys are erased permanently. Recovery is possible only with the original 24-word backup.

Q: Is it safe to use Trezor Model One with public Wi-Fi when connected to a laptop?A: Yes — the device operates offline. Network exposure affects only the host machine, not the Trezor’s internal secure element.

Q: Does Trezor Model One support SegWit addresses natively?A: Yes — both nested (P2SH) and native (bech32) SegWit formats are enabled by default in all Bitcoin accounts.
