In an era where digital assets are increasingly central to personal finance, securing your cryptocurrency has never been more critical. Enter Tangem — a next-generation hardware wallet designed to offer bank-grade security in a sleek, card-sized form factor. Combining cutting-edge chip technology with user-friendly design, Tangem redefines how individuals store, manage, and protect their crypto holdings.
Whether you're new to blockchain or a seasoned investor, Tangem delivers peace of mind through offline key generation, military-grade durability, and complete user control — all without relying on third-party servers or cloud backups.
What Is Tangem?
Tangem is a hardware cryptocurrency wallet that stores your private keys on a secure, tamper-proof microchip embedded in a credit card-sized device or wearable ring. Unlike software wallets vulnerable to malware and online attacks, Tangem keeps your keys completely offline — generated and stored within the chip itself, never exposed to the internet.
This means your crypto remains safe from hacking, phishing, and remote exploits. With support for thousands of cryptocurrencies across multiple blockchains, Tangem offers a unified, secure solution for managing diverse digital portfolios.
How Does Tangem Work?
The core innovation behind Tangem lies in its secure element chip, co-developed with Samsung Semiconductors and certified to EAL6+ — the same security standard used in biometric passports and government ID cards.
Here’s how it works:
- Offline Key Generation: During activation, the Tangem chip generates a cryptographically secure private key using a True Random Number Generator (TRNG). This process occurs entirely offline — no network connection, no data transmission.
- Encrypted Communication: When you sign a transaction via the Tangem app, your smartphone establishes a secure Bluetooth or NFC connection with the card or ring. The private key never leaves the chip; only the signed transaction is sent back.
- Immutable Storage: The private key is permanently stored inside the chip. There are no copies — not on your phone, not in the cloud, not on any server. It exists only within the physical device.
This architecture ensures zero exposure to cyber threats, making Tangem one of the most secure ways to hold cryptocurrency.
Key Features That Set Tangem Apart
✅ Unmatched Security
- No seed phrase required (optional): Keys are generated and stored directly on the chip.
- EAL6+ certified chip: Resists physical tampering, side-channel attacks, and cloning.
- No internet exposure: Private keys never leave the device.
- Firmware audited twice: Independently verified by Kudelski Security (2018) and Riscure (2023) — no backdoors, no vulnerabilities found.
✅ Durability & Reliability
- Waterproof, dustproof, and resistant to extreme temperatures.
- Survives X-rays, electromagnetic pulses (EMP), and electrostatic discharge (ESD).
- No battery, screen, or moving parts — just a robust antenna-integrated chip.
✅ User-Centric Design
- Activates in under 3 minutes.
- Works with iOS and Android smartphones via NFC.
- Supports multi-card setups: Use up to three cards or rings with identical access — lose one? Access remains via the others.
✅ Privacy-First Philosophy
- Open-source app available on GitHub — fully transparent and community-verified.
- No personal data collection.
- No transaction processing on Tangem servers — every action happens locally between your device and blockchain.
Why Choose a Hardware Wallet?
Cryptocurrency security starts with controlling your private keys. Software wallets (hot wallets) store keys on internet-connected devices — making them convenient but vulnerable. In contrast, hardware wallets like Tangem keep keys offline, drastically reducing attack surfaces.
Key benefits include:
- Protection against malware and phishing
- Immunity to exchange hacks
- Full ownership and control of assets
- Long-term storage safety (ideal for "cold storage")

Tangem Wallet Setup & Recovery
Setting up your Tangem wallet takes less than three minutes:
- Download the free Tangem app.
- Tap your card or ring to your smartphone.
- Follow prompts to activate and set a PIN code.
You can create a wallet with:
- A single card
- A set of two cards
- A set of three cards (recommended for redundancy)
With a 3-card setup, losing one card doesn’t compromise access — use either of the remaining two to recover funds. However, with only two cards, losing one and forgetting your access code may result in permanent loss — so proper backup practices matter.
While seed phrases are optional, they allow importing keys from other wallets. But remember: written seed phrases can be copied or stolen — unlike Tangem’s chip-based keys, which cannot be extracted.
Built to Last: 25-Year Warranty
Tangem guarantees its wallets for 25 years when used as intended. Encased in sealed plastic construction, the chip can withstand pressures equivalent to those at the bottom of the Mariana Trench. With no components prone to failure, Tangem devices are built not just for daily use — but for generational wealth storage.
Frequently Asked Questions (FAQ)
Q: Can my Tangem wallet be hacked?
A: No known vulnerabilities exist. The chip is EAL6+ certified, firmware is audited and non-upgradable (preventing remote exploits), and private keys never leave the device.
Q: Do I need internet to use Tangem?
A: Only your smartphone needs internet to broadcast transactions. The Tangem card/ring operates entirely offline.
Q: What happens if I lose my card?
A: If you have multiple cards in a set, use another to access funds. For single-card users, losing the card means permanent loss unless you’ve backed up via seed phrase (if enabled).
Q: Is the Tangem app safe?
A: Yes. It’s open-source, doesn’t store private keys, and only acts as an interface to scan cards and sign transactions.
Q: Can I use Tangem without a smartphone?
A: Not currently. You need a compatible NFC-enabled smartphone to interact with the wallet.
Q: Does Tangem support all cryptocurrencies?
A: It supports thousands of tokens across major blockchains including Bitcoin, Ethereum, Solana, Litecoin, Dogecoin, and more — with ongoing additions.
A Trusted Choice Backed by Users
Tangem has shipped over 4 million units since launch — and not a single card has been hacked. This track record reflects its commitment to security, transparency, and user empowerment.
