A hardware wallet company established in 2017 and based in Zug, Switzerland, has emerged as a prominent player in the cryptocurrency storage market. Tangem offers a unique blend between traditional USB-style devices, such as Ledger and Trezor, and slim card designs like CoolWallet. Designed for self-custody, Tangem’s wallets function similarly to a contactless bank card, enabling users to confirm transfers with a single tap rather than plugging into a PC. The demand for this innovative approach is underscored by the production of over six million cards.
Currently, users can manage NFT collections through the Tangem mobile app across multiple networks, including Ethereum and Solana. Each Tangem wallet operates as a contactless smart card paired with its mobile application. Upon activation, the secure element within the card generates and retains the private key, ensuring that signatures are executed only when the card is tapped to the NFC area of a smartphone.
The design features a battery-free card that requires no cable, relying on ISO 14443 Type A, the standard for tap-to-pay transactions. Users have the option to derive a private key from a seed phrase, allowing for compatibility with existing wallets.
In terms of specifications, Tangem wallets incorporate a certified Samsung S3D350A secure element, ensuring robust security features. They support over 85 blockchains and can recognize more than 16,000 cryptocurrencies and tokens. The cards operate effectively under extreme conditions, with an operating temperature ranging from -25 °C to 70 °C, and come with a 25-year replacement warranty.
Three main pillars shape the daily interactions with Tangem wallets: simplicity, extensive asset coverage, and a mobile-centric application. Users benefit from the ability to consolidate multiple assets without the hassle of managing numerous apps or additional seed cards.
The app simplifies user experience, offering a way to add networks and create accounts effortlessly. With a focus on ease of use, actions such as checking balances and making transfers are designed to be straightforward, allowing for biometric authentication for added security.
Tangem’s card design prioritizes portability, fitting comfortably into a pocket. The wallet’s durability, coupled with its simple backup process of using duplicate cards, enhances user confidence by allowing for easy recovery in case one card is lost. The security architecture leverages the secure element to store private keys directly within the card, minimizing exposure to potential threats.
Independent audits from Kudelski Security and Riscure have confirmed the integrity of Tangem’s firmware, finding no vulnerabilities that might expose private keys or indicate unsafe backdoor access. This reinforces the wallet’s secure design.
Setting up the Tangem wallet is remarkably swift, enabling users to go from unboxing to initializing the wallet within minutes. A typical setup involves downloading the app, scanning the card, and following an intuitive onboarding wizard.
Daily use is streamlined, requiring just a tap to sign transactions. Users can receive or send cryptocurrencies, buy assets using fiat, and swap tokens seamlessly within the app, which features transparent fee structures and no hidden charges.
In comparison to other hardware wallets, Tangem distinguishes itself with its focus on mobile usage and simplicity. This makes it particularly suitable for long-term holders and first-time users who appreciate an ease-of-use approach. However, it may not be the best fit for desktop-based traders or high-volume DeFi participants who may prefer wallets with more complex integration options.
Overall, Tangem has carved a niche for itself by providing a reliable, portable solution for cryptocurrency storage. Its combination of physical security, ease of use, and extensive asset coverage makes it an appealing choice for users looking for self-custody options in a mobile-friendly format.
