Open-Source Transparency and Blockchain-Based Security

First, let's start with the technical aspects and get the boring stuff out of the way. Tangem's firmware and cryptographic protocols are open-source, allowing anyone to audit and verify the security of the system. Unlike traditional wallets that store private keys in a centralized manner or require users to jot down seed phrases, Tangem ensures your assets remain secure by leveraging the blockchain. This means your crypto is never stored on the physical Tangem card or ring itself but resides securely on the blockchain, with your wallet acting as the access key.

Simple Setup and Hassle-Free User Experience

Setting up a Tangem wallet is incredibly simple. Unlike other hardware wallets that involve multiple steps, including writing down and securely storing a seed phrase, Tangem’s design eliminates these complexities. Users simply tap the Tangem card or ring against their smartphone, install the Tangem app, and follow the on-screen instructions. The process is quick, intuitive, and requires no technical knowledge.

Once set up, users can send and receive cryptocurrency with a simple NFC tap, making transactions seamless. The wallet supports multiple cryptocurrencies, ensuring flexibility for users managing diverse digital assets.

No Need for a Seed Phrase—Ultimate Security Without the Hassle

One of the standout features of Tangem is the removal of the traditional seed phrase. In conventional wallets, losing a seed phrase often means losing access to funds permanently. Tangem eliminates this risk by using a secure chip inside the card or ring to authenticate transactions directly with the blockchain. This makes it virtually impossible for hackers or malicious actors to access your assets without the physical Tangem device.

The Tangem wallet comes with 2-3 physical cards and the ring if you order it, so it’s important to store your cards safely and in separate locations to protect against loss due to events like floods or fires.

What Happens if You Lose Access to the Tangem App?

If you lose access to the Tangem app (for instance, due to a lost or reset phone), there’s no need to worry. Simply download the Tangem app on a new device and tap your Tangem card or ring to regain access. Because authentication happens via NFC and is tied to the physical card or ring, there’s no need for passwords or recovery phrases.

What Happens if You Lose Your Tangem Cards and Ring?

Losing your Tangem card or ring can be concerning, but there are built-in safety measures. Users are advised to activate backup cards, which can be linked during the initial setup. If one card or ring is lost, the backups can be used to restore access. If all linked cards are lost and no backup exists, the assets remain on the blockchain, but access is permanently lost.

Again, store your cards and ring in a safe place and, if possible, keep them in separate locations.

Efani + Tangem: A Complementary Solution

Most crypto users with cold storage solutions also have an online wallet or exchange account to trade, send, or receive crypto easily. These online accounts are vulnerable to mobile SIM swaps, where hackers can reset passwords to your crypto, email, social media, business accounts, web hosting, payroll, and more.

If you're a U.S. resident, you can switch your mobile carrier to Efani and choose between AT&T or Verizon. With SIM swap security built in by default, Efani enhances your privacy and provides a $5 million insurance policy for added protection. By combining Efani with a Tangem wallet, you can keep not only your crypto secure but also your personal and business accounts.
