The Swiss company Tangem has developed a crypto wallet without batteries and wires
Tangem Wallet is a new type of cold wallets for cryptocurrency, created for smartphone users. So if you are looking for a crypto wallet that will allow you to access your crypto assets on the go and store various coins and tokens, then this Tangem wallet review will answer your questions.
Tangem is a Swiss company headquartered in Zug. Its branches are located in North America, Eastern Europe and the Asia-Pacific region. The company has been developing hardware cold wallet technology for crypto assets in 170 countries since 2017.
Design
The hardware wallet is made in the form of a card with a secure chip, which generates private and public keys for managing cryptocurrencies at the moment of card activation. To work with the card, you only need a smartphone (Android / iOS) that communicates with the card via NFC. It will not work to conduct transactions on a computer: the developers focused on security and convenience, so the wallet does not
provides no connectors, wires, battery, display and buttons. In addition, this ensures the durability of the device - you can safely put the card in the safe, on the far shelf, give it to the heirs for safekeeping and not worry that the device will discharge or fail. And data transmission via NFC is much safer than via Bluetooth.
Features of use
For beginners in the world of cryptocurrencies and blockchain technology, Tangem Wallet will seem more convenient than other cold wallets: to use it, you only need to download the Tangem application to your mobile phone. When activated, the chip creates keys for cryptocurrencies, and in the future they never leave the key. If you need to make a transaction, the mobile application will send the transaction data to the chip, the chip will sign with a private key and return it to the application, which will already send the signed transaction to the blockchain. The entire activation takes about a couple of minutes, the application interface is intuitive.
The speed of activation is also achieved due to the fact that Tangem does not have a stage of establishing a seed phrase. To restore access in case of loss of the wallet, other manufacturers offer to install and remember a long seed phrase, the storage of which is unsafe, because compromising the seed phrase means the loss of all crypto assets. Whereas in Tangem, instead of a seed phrase, they offer to link up to three cards to one wallet (Tangem Wallet is sold in sets of 2 or 3 cards), and in case of loss of one, use others to restore access. Old-timers may be scared by such innovation, because they are used to relying on the seed phrase. But Tangem believes that storing a backup card is much easier and safer than memorizing or writing down and saving a long seed phrase.
Safety
When it comes to hardware crypto wallets, you always need to first study the manufacturer, user reviews, and make sure that certificates are available. You should trust your crypto assets to trusted companies, not dark horses. Tangem is ready to dispel all doubts of buyers. The Tangem chip has the highest level of certification among direct competitors - CC EAL6+. The same level of chip protection is used in electronic passports. The service life of the chip is more than 25 years.
The firmware of the wallet has been independently audited by the Swiss company Kudelski Security, which issued a certificate of the absence of vulnerabilities. And the source code of the Tangem mobile application is posted in the Github repository.
Multicurrency
Tangem Wallet supports more than 6000 cryptocurrencies and 19 networks: Bitcoin, Ethereum, BNB Smart Chain, BNB Beacon Chain, Ripple, Solana, Cardano, Avalanche C-Chain, Dogecoin, Polygon, Litecoin, Bitcoin Cash, Stellar, Fantom Opera, Tezos, RSK, TRON, Ethereum Classic, Arbitrum.
One of the disadvantages is that during primary use, only Bitcoin and Ethereum are initially visible on the main screen. But it's easy to add the remaining tokens to the main screen, just use the "Add tokens" function and customize the application for yourself.
Verdict
Tangem Wallet is one of the most secure and advanced wallets on the market, ideal for experienced cryptocurrency users to securely store crypto assets. Novice crypto enthusiasts will be won over by the wallet's ease of use, intuitive application interface and low price.
