Trezor vs Tangem, what is the difference?

Trezor vs Tangem is a comparison between two kinds of cold wallet. Trezor makes small devices with a screen that connect by USB-C or, on the Safe 7, Bluetooth. Tangem makes bank-card-sized wallets, and a ring, that you tap against a phone. Both keep private keys in a secure element chip. This page explains the differences and does not rank them.

Trezor vs Tangem wallet, how do the designs differ?

A Tangem card has no battery, screen or buttons. It draws power from the phone's NFC signal, and the Tangem app on iOS or Android shows balances and transaction details. Tangem's site does not mention desktop use, and its buying guide lists phone models without full NFC that cannot complete backups. More is in what is Tangem wallet.

Trezor devices carry their own display. The Safe 5 has a 1.54-inch color touchscreen and connects by USB-C, while the Safe 7 has a 2.5-inch touchscreen, a battery and encrypted Bluetooth. A screen on the device lets you check an address or amount there rather than trusting the computer or phone.

Trezor or Tangem, how do backups work?

This is the biggest practical difference. By default, Tangem generates the key on the card's chip and copies it to the other cards in a set of two or three. Any card can then open the wallet, and Tangem advises storing them in separate places. If every card is lost and no seed phrase was created, the funds cannot be recovered. Tangem also lets you generate or import a 12 or 24-word seed phrase instead.

Trezor creates a wallet backup of 12, 20 or 24 words, or an advanced multi-share backup that splits recovery across several shares. Our guide to what a seed phrase is explains why that backup controls everything.

Trezor vs Tangem cold wallet, how does security compare?

Both use chips certified to Common Criteria EAL6+. Tangem says its chip was developed with Samsung Semiconductors and its firmware was reviewed by Kudelski Security and Riscure. Cointelegraph describes that firmware as proprietary and not updatable after manufacture. Tangem's app code is on GitHub.

Trezor takes the open route, saying its code is fully open source so anyone can review it. The Safe 7 adds a second secure element, TROPIC01, which Trezor says is fully auditable.

How do Trezor, Tangem and Ledger compare?

On coverage, Tangem lists more than 14,100 assets across more than 90 networks, and Trezor says it supports hundreds of coins and tokens, with more available through third-party wallet apps. Trezor also sells a Bitcoin-only Safe 7. Ledger is the other common name in this group. Our Ledger vs Tangem and Trezor vs Ledger guides cover those pairings.
