Tangem vs Trezor Safe 7: Two Different Philosophies of Safety

This comparison is between two wallets I have used for years (Tangem for about 3 years, Trezor for about 2.5). They represent two opposite ideas of what hardware wallet safety actually means. Both are strong, and both have shown vulnerabilities, so this covers backup, security and firmware, ease of use, features, supported coins, price, and track record.

The fundamental difference: two philosophies of safety

The Trezor Safe 7 is built around maximum hardware defense: three independent secure chips, fully open-source firmware, post-quantum cryptography for firmware updates, a large color touchscreen, Bluetooth and wireless charging. It is one of the most advanced hardware wallets you can buy, for people who want the strongest technical security and want to verify it themselves.

Tangem takes the opposite approach, built around simplicity and removing the things that cause most real-world losses: lost or stolen seed phrases, setup mistakes, and firmware-update risk. No screen, no battery, no buttons, no cable, no firmware updates at all. A card with a single EAL6+ secure element chip, tapped to your phone.

One is a fortress with three layers of defense. The other is a simple card that removes the things people normally mess up. Both are safe, they just protect against different risks.

Backups and seed phrases

The Safe 7 uses a 24-word seed phrase by default, and also offers Multi-share Backup (Shamir's Secret Sharing) to split the seed into shares and remove the single point of failure, though that is optional and you set it up yourself.

Tangem does not use a seed phrase by default. The private key is generated and encrypted inside the card, and you get 2 or 3 identical cards, each a full backup of the others, so as long as you have one card you have access. The cards are rated for around 25 years, waterproof and dustproof, and carry a 25-year warranty, versus Trezor's standard 2-year warranty. Seed phrase backup is available on Tangem too, but seedless is the recommended default.

By default, Tangem is safer against loss and user mistakes. The Safe 7 can match it, but only once you configure Multi-share Backup yourself.

Security chips and firmware

The Safe 7 has three independent chips from three manufacturers: the TROPIC01 (the first fully open and auditable secure element in any hardware wallet), an Infineon EAL6+ secure element, and a main microcontroller. If one chip were compromised, the other layers still protect your funds. Tangem uses a single EAL6+ certified secure element, the same certification grade used in biometric passports, just one chip rather than three. Both are strong on chip security; the Safe 7 has more layered defense.

Firmware is where they really diverge. The Safe 7 receives firmware updates, with post-quantum cryptography protecting the update process so an update cannot be tampered with. Tangem cards cannot be updated at all. The trade-off is real: Tangem cannot patch bugs or add features at the card level, but it also has no firmware attack surface, so there is no way a future malicious update could ever compromise the card. On openness, the Safe 7 runs fully open-source firmware; Tangem's card firmware is closed (independently audited), while its mobile app and developer tools are open source.

Both wallets have shown vulnerabilities only under lab conditions requiring physical possession and specialized equipment, so neither is a remote-hacking risk for normal users. One honest difference: Tangem has a blind signing risk because the card has no screen, so you trust the phone's display, whereas the Safe 7's screen lets you verify each transaction on the device. Tangem's blind signing risk has not led to a single known user losing funds, but it is a real advantage for the Safe 7, especially for DeFi and smart contracts.

Connectivity, battery and durability

The Safe 7 connects over Bluetooth, USB-C and wireless charging, so it works with both a computer and a phone. Tangem works purely through NFC, tapping the card to your phone. NFC has a much shorter range than Bluetooth, which means a smaller potential attack surface. Tangem also has no battery, so nothing degrades over time, while the Safe 7's built-in battery will slowly lose capacity over years like any battery.

Usage

Tangem takes about 1 to 3 minutes to set up and is used entirely through the phone app with a tap to approve. The Safe 7 takes longer to set up and runs through Trezor Suite on desktop or mobile, which is a little less familiar but easy once you adjust. Tangem is the simpler experience but mobile only; Trezor supports desktop and mobile. Tangem's recent Smart Gas feature also lets you pay network fees in stablecoins like USDC instead of the network's native coin (on Ethereum, BNB Smart Chain, Polygon, Arbitrum and Base), which removes a real friction point for beginners.

Features and supported coins

Both are very strong here, effectively a tie. Tangem supports 16,000+ tokens across 87+ networks, slightly more network breadth, while the Safe 7 has broad support plus deeper DeFi integration through WalletConnect. Both now generate fresh receiving addresses on UTXO networks like Bitcoin (Trezor for years, Tangem added it in v5.39 as "Dynamic Addresses"). The Safe 7 has built-in Tor in Trezor Suite for network-level privacy, which Tangem does not; Tangem has Smart Gas, which Trezor does not.

Price

A Tangem set costs around $55 for two cards or $70 for three. The Safe 7 costs around $249, roughly four times more, because you are paying for a far more advanced device: three chips, a touchscreen, Bluetooth, wireless charging and post-quantum firmware updates.

Track records

Tangem, the company, has been around since 2017, with cards shipping from 2021, and a clean record with no incidents affecting user funds. Trezor has been around since 2014 as the original hardware wallet company, the longest track record in the industry. Trezor did have a third-party support-tool breach in early 2024 that exposed the email addresses of up to around 66,000 users, but no funds were affected and it was handled transparently. Both are clean compared to Ledger's history.

My conclusion

Get the Trezor Safe 7 if you want the most advanced wallet on the market: a fortress with three secure chips, fully open-source firmware, Tor for network privacy, post-quantum-secured updates, and verifiable security, and you are comfortable managing a seed phrase or setting up Multi-share Backup and paying around $249.

Get Tangem if you want a wallet that is hard to mess up, want to skip seed phrases entirely, want the simplest setup and use, want the cheapest solid option, want a card rated for 25 years and waterproof, and want to avoid firmware-update risk entirely.

I personally use both. I keep long-term holdings on the Safe 7 since I am comfortable with a seed phrase, and I use Tangem mainly for fast, active daily use, some long-term storage too. If I had to pick one for a beginner, it would be Tangem. For those who can handle a seed phrase or multi-share backup and want the best security possible, I would point them to the Safe 7.
