Key terms

Hardware wallet

A physical device dedicated to holding cryptocurrency private keys offline. Signs transactions internally; keys never leave the device. Ledger and Trezor are the leading consumer brands.

Ledger Nano S Plus

Entry-level hardware wallet from Ledger ($79 at ledger.com). CC EAL6+ secure element, USB-C, supports 5,500+ cryptocurrencies. Closed-source firmware on a secure element.

Trezor Safe 3

Entry-level hardware wallet from Trezor ($79 at trezor.io). EAL6+ secure element, OLED display, USB-C. Open-source firmware. Default 12-word seed (24 optional).

BIP-39 seed phrase

A 12 or 24 word phrase that encodes the master key for a cryptocurrency wallet. Standardized in Bitcoin Improvement Proposal 39, September 2013. The 2048-word wordlist has unique 4-letter prefixes.

PIN

Personal Identification Number used to unlock a hardware wallet. Defends against physical theft. Length matters: 4 digits (default minimum) is weak; 8 digits is reasonable.

Passphrase (BIP-39 25th word)

Optional additional secret combined with the seed phrase to derive a different wallet. Without it, the seed reveals nothing useful. Provides plausible deniability and defense against seed theft.

Genuine Check

A cryptographic attestation performed by Ledger Live during initial device setup, verifying that the connected device is a genuine Ledger and not a tampered or counterfeit unit.

Tamper-evident packaging

Packaging designed to show visible evidence of opening or interference. Trezor uses holographic seals; Ledger relies on the device internal Genuine Check rather than physical seals.

Firmware update

Software update for a hardware wallet device. Addresses security issues, adds features, supports new cryptocurrencies. Should be applied promptly when released by the official manufacturer.

Verify on device

The practice of confirming transaction details (destination address, amount) on the hardware wallet screen rather than relying solely on the computer display. Defends against malware-corrupted display on the host.

Test transaction

A small initial transaction (typically $5 to $20) to validate the round trip of receiving and spending from a newly set up wallet, before moving meaningful amounts.

Address poisoning

An attack where attackers send 0-value transfers from addresses matching your contacts first/last characters, hoping you copy the wrong address from transaction history.
