The Tangem Wallet is a modern take on the hardware wallet, a sleek smart card that lets you store and manage your cryptocurrency securely, without cables, batteries, or complicated software. It’s made by Tangem AG, a Swiss company founded in 2017 and based in Zug, often called “Crypto Valley.”

Instead of looking like a USB stick (think Ledger or Trezor), the Tangem wallet looks and feels like a credit card. You simply tap it against your smartphone using near-field communication or NFC (the same technology used for contactless payments) to confirm transactions. The goal is simple: make self-custody feel as easy and natural as tapping your debit card.

Over the years, Tangem has shipped millions of wallets globally and built a loyal user base, especially among beginners who want the safety of cold storage without the fuss of seed phrases or cables.

Tangem Wallet: Functions and Services

Tangem is built around one clear idea: secure crypto shouldn’t be complicated. Everything revolves around the card and the Tangem app, which together form your personal vault.

Supported Assets and Networks

Tangem supports a huge range of digital assets, including Bitcoin (BTC), Ether (ETH), Solana (SOL), Cardano (ADA), Polygon (POL), and most major stablecoins, plus thousands of ERC-20 and BEP-20 tokens. With support for over 85 blockchains, it’s one of the most broadly compatible wallets in its class.

The app automatically recognises your tokens once you add a network, so you can manage your entire portfolio in one place. Updates roll out frequently to add new chains and assets, keeping Tangem relevant in the fast-moving crypto world.

The Tangem App and Daily Use

The Tangem app is where all the action happens. Once installed on your phone, it guides you through setup and everyday use, such as checking balances, sending or receiving crypto, swapping coins, or staking supported tokens.

When you want to send crypto, you simply tap your Tangem card to your phone. The card signs the transaction inside its secure chip, your private key never leaves the device. It’s a smooth, almost “tap-to-pay” experience, but for digital assets.

You can also use WalletConnect to access decentralized finance (DeFi) apps or  non-fungible token (NFT), signing each action with your physical card. This keeps your funds safe even when interacting with external platforms.

NFTs, Staking and Swaps

Tangem now supports NFTs directly in the app, with compatibility across multiple networks such as Ethereum, Solana, and Polygon. You can also stake certain assets (like ADA or SOL) to earn rewards, and use Tangem Express, an in-app exchange aggregator, to swap tokens through integrated partners like Changelly and 1inch.

All this happens without ever handing over your keys, the card stays in control.

On- and Off-Ramp Capabilities of the Tangem Wallet

Tangem makes it easy to move between fiat and crypto. Through its partnered services inside the app, you can buy crypto with a debit card or Apple Pay/Google Pay in supported countries. Selling works similarly, with crypto-to-fiat conversions handled by trusted partners such as MoonPay or Mercuryo.

Tangem itself doesn’t process these payments, it provides a secure environment while the external provider handles the transaction. Fees and supported regions depend on the partner, so always double-check before buying or selling.

Is the Tangem Wallet Safe to Use in 2025?

Yes, Tangem is one of the most secure mobile-first wallets on the market, but as always, your safety depends on how well you handle your backups and cards.

Security Architecture

Inside each Tangem card is a Samsung secure element (EAL6+ certified), the same class of chip used in modern passports and banking systems. When you set up the wallet, the card’s chip generates your private key internally and never exposes it, not even to the Tangem app.

Every transaction you make must be approved by physically tapping the card to your phone. This physical step makes remote hacks virtually impossible. Even if your phone were infected with malware, it couldn’t spend your funds without the actual Tangem card present.

The firmware is immutable, meaning it’s locked at the factory and can’t be updated later. This design prevents tampered firmware or fake updates from introducing vulnerabilities.

Backup and Recovery

Instead of relying solely on a written seed phrase, Tangem lets you set up 2- or 3-card backup sets. Each card holds an identical copy of your wallet’s private key. Lose one card? The others still work. Lose all of them? You lose access, so spreading them across safe locations is crucial.

For users who prefer traditional recovery, Tangem also offers an optional 12- or 24-word seed phrase mode for compatibility with other wallets. It’s flexible, letting you choose between convenience and familiarity.

Independent Audits and Transparency

Tangem’s security has been independently audited by two respected firms, including Kudelski Security and Riscure. Both audits found no evidence of backdoors or vulnerabilities that could expose private keys.

While Tangem’s firmware is closed-source, its mobile apps and SDKs are open-source on GitHub, so anyone can inspect how the app handles communication. The closed firmware limits customization but also reduces potential attack surfaces, a deliberate trade-off for reliability.
