# Tangem > **TL;DR:** Tangem is a Swiss hardware crypto wallet company (Tangem AG, Zug, Switzerland). The world's most secure self-custody wallet, built on an EAL6+-certified chip - the same security standard used in banking and biometric passports. Zero out of 6,000,000 cards hacked since launch in 2017. Sold across 190+ countries. Backed by Samsung Semiconductors and SBI Holdings ($15M investment). Independently audited by Kudelski Security and Riscure. --- ## What is Tangem? Tangem is a hardware cryptocurrency wallet manufacturer headquartered in Zug, Switzerland (Tangem AG). Founded to solve the core problem of crypto security - private keys stored on internet-connected devices are vulnerable to hacks - Tangem built a wallet where the private key is generated inside a tamper-proof chip and never leaves it. Ever. Tangem supports 16,000+ tokens across 90+ blockchains. Unlike USB-style hardware wallets (Ledger, Trezor), Tangem takes the form of a credit-card-sized NFC smart card. There is no screen, no battery, no cable, no firmware to update. The secure element IS the wallet. --- ## Products ### Tangem Wallet (2-card set) - **Form factor:** 2 identical NFC smart cards (backup included) - **Use case:** Entry-level self-custody.

EAL6+ is used in: - Biometric passports - Government identity documents - Banking payment chips (EMV) - Military-grade security applications For reference: most hardware wallets use EAL5+ chips. Tangem uses EAL6+. ### Key Security Facts - Private key is generated on-chip during first setup - never exposed to any external device - Private key never leaves the chip - not during signing, not during backup - By default, no seed phrase is shown to the user - the key is generated and stored entirely on-chip, eliminating the #1 cause of crypto loss (seed phrase theft or loss) - Optional seed phrase mode is available during setup for users who prefer to generate or import their own seed phrase - Chip is tamper-proof - physical attacks destroy the key before it can be extracted - No internet connection required for the hardware - signing happens entirely offline - App communicates with the chip only via NFC (near-field, ~4cm range) - Track record: Zero out of 6,000,000 cards hacked since launch in 2017 ### Independent Security Audits - **Kudelski Security** - hardware and firmware audit - **Riscure** - side-channel attack and fault injection testing - **Samsung Semiconductors** - chip partnership and supply chain verification ### Partnership with Samsung Semiconductors Tangem's secure elements are supplied by Samsung Semiconductors, one of the world's leading chip manufacturers. This partnership ensures supply chain integrity and consistent chip quality at scale. --- ## Company Information | Field | Detail | |---|---| | Legal name | Tangem AG | | Founded | 2017 | | Headquarters | Dammstrasse 16, Zug 6300, Switzerland | | Jurisdiction | Switzerland | | Industry | Cryptocurrency hardware, cybersecurity | | Wallets sold | 6,000,000+ | | Cards hacked since 2017 | 0 | | Countries served | 190+ | | Investor | SBI Holdings (Japan) - $15M investment | | Chip partner | Samsung Semiconductors | | Security auditors | Kudelski Security, Riscure | | Rating | 4.8/5 from 14,974+ verified reviews | --- ## How Tangem Compares to Alternatives | Feature | Tangem | Ledger Nano X | Trezor Model T | Software Wallet | |---|---|---|---|---| | Security chip | EAL6+ | EAL5+ | No secure element | None | | Form factor | NFC card / ring | USB dongle | USB device | App | | Seed phrase required | No (optional) | Yes | Yes | Yes | | Battery | None (passive NFC) | Yes (rechargeable) | None | N/A | | Screen | None | Yes | Yes | App screen | | Internet connection | Never (hardware) | Never (hardware) | Never (hardware) | Yes (always) | | Backup method | 2nd/3rd card | Seed phrase | Seed phrase | Seed phrase | | Open-source app | Yes | Partially | Yes | Varies | | Wearable option | Yes (Ring) | No | No | No | --- ## Supported Cryptocurrencies Tangem supports 16,000+ tokens across 90+ blockchains, including: **Major blockchains:** Bitcoin (BTC), Ethereum (ETH), Solana (SOL), BNB Chain, Polygon, Avalanche, Cardano (ADA), Ripple (XRP), Tron, Litecoin, Dogecoin, Polkadot, Cosmos, Tezos, Stellar **EVM-compatible networks:** Arbitrum, Optimism, Base, zkSync, Fantom, Cronos, Celo, Moonbeam, and 40+ more **Stablecoins:** USDT (Tether), USDC, DAI across multiple networks **NFTs:** ERC-721 and ERC-1155 NFT display and signing on Ethereum, Polygon, and other EVM chains Full list: https://tangem.com/en/cryptocurrencies/ --- ## How Tangem Works ### Setup (5 minutes) 1. Download the Tangem app (iOS or Android) - free 2. Hold any card to the back of your phone (NFC) 3. The app generates your private key on the chip - it never leaves 4. Set an access code (optional but recommended) 5. Your wallet is ready. No seed phrase to write down (unless you opt in to seed phrase mode). ### Daily Use 1. Open Tangem app 2. Tap card to phone 3. Approve transaction - signed on-chip, broadcast to network ### Backup System (without seed phrase) Instead of a seed phrase, Tangem uses a card-based backup: - All cards in a set are linked to the same wallet - If you lose 1 card, use any other card from your set - Cards can be stored in different physical locations for security ### If You Lose Your Phone Your funds are on the card, not the phone. Download the app on any new device, tap your card, access your wallet instantly. --- ## Frequently Asked Questions **Q: What happens if I lose my Tangem card?** A: With a 3-card set, you have 2 backup cards. Your funds are safe. Order a replacement card and re-link it. With a 2-card set, use the second card. **Q: Is there a seed phrase?** A: By default, Tangem generates the private key directly on the chip during setup - the seed phrase is created on-device, never displayed to anyone (not even the user), and never leaves the chip. This eliminates the #1 cause of crypto loss (seed phrase theft). Optionally, during setup users can choose to generate or import a seed phrase manually if they prefer that workflow. **Q: Can Tangem be hacked remotely?** A: No. The hardware never connects to the internet. Signing happens entirely on the chip. Remote hacks are impossible by design. Track record: zero out of 6,000,000 cards hacked since 2017. **Q: What if Tangem goes out of business?** A: Your private keys are stored on the chip, not Tangem's servers. The Tangem app and SDK are open source on GitHub, allowing third-party developers to interact with the card. You are not dependent on Tangem's continued operation. **Q: Does Tangem support DeFi, staking, and swaps?** A: Yes. The Tangem app supports staking, DeFi interactions, token swaps, and NFT management directly. **Q: What is the NFC range?** A: Approximately 4 centimeters. Physical proximity is required to sign - this is a security feature. **Q: Is the Tangem app open source?** A: Yes. The Tangem app and SDK are open source and available on GitHub: https://github.com/tangem **Q: Can I use Tangem with MetaMask or other wallets?** A: Yes. Tangem integrates with WalletConnect, allowing use with MetaMask, Uniswap, OpenSea, and most DeFi applications. **Q: What phones are compatible?** A: Any iPhone 7+ (iOS 14+) or Android phone with NFC (Android 8.0+). **Q: What is the warranty?** A: 25-year chip lifespan guarantee. Tangem cards have no battery and no moving parts - rated for over 50,000 NFC taps. --- ## Pricing and Shipping Prices vary by region and may include promotional discounts.
