Businesses and organizations are built on trust. Trust that your trades are legitimate, that your products aren’t counterfeit, and that you are exactly who you say who are. Tangem elevates that trust to an entirely new level.

Our chip-to-chain technology creates a form of digital trust unlike anything the world has ever seen.

There’s no need for intermediary validation. No more concerns about authenticity or fear of fraud.

It’s rock-solid trust, delivered in the convenience of a chip and controlled with any mobile device.

Tangem springboards CBDC (Central Bank Digital Currencies) Into Reality

CBDC is an imminent reality and it should be our collective priority; it will be the most important trend for the future of money and payments over the next decade. The path we take will have a major implication for privacy, monetary sovereignty, geopolitics and financial inclusion. It is essential therefore that there is no tradeoff between privacy, security, speed and accessibility.

Tangem’s Swiss Army Knife


At Tangem we have created the Swiss Army Knife that addresses all these critical features, with the aim to be the toolkit to catapult CBDC into a reality for ALL. We are simultaneously a programmable privacy platform as well as a secure hardware tool, in the form of an NFC card, which acts as a distribution option for CBDC creating an important onramp for the financially excluded, whilst enabling responsible innovation.
Trust as Ambassador


Trust is key in this payments revolution and we built our technology with trust as our ambassador who links an unbreakable chain between citizens’ pockets and National Treasury records.

The Power of Blockchain Explained

Tangem’s benefits extend far beyond rock-solid security. Realize unimaginable business advantages with the power of Tangem. All with the tap of a key unlike any the world has seen.



Blockchain does not store any information in a central location. Instead, the blockchain is copied and spread across a network of computers. By spreading information across this network, blockchain is practically tamper proof.


Blockchain uses public-key cryptography to deliver unparalled security.  It validates the identity of the sender while Tangem’s private key maintains the immutability of the transaction.


Blockchains are inherently immutable, meaning they are permanent and cannot be altered. This permanence is key to how Tangem facilitates trust and the absolutely rock-solid integrity of data.


Blockchains can be audited to explore transactions and validate participant claims of transaction. The auditability establishes consensus by all participants and maintains the blockchain’s validity as it grows.

Our Story

Tangem is the result of over a decade of research and development in microchip technology.

Our first application was in the cryptocurrency sector, where we pioneered plastic cards for various cryptocurrencies as self-custody instruments.

The cards proved our technology to the world and highlighted the limitless possibilities of our chip-to-chain technology. They are currently retailed on Tangemcards.com and by selected partners.

Since delivering this proof-of-concept to the market, Tangem has worked with leading financial services and technology companies to bridge their exciting use cases for blockchain with practical, tangible products.

Tangem operates globally with headquarters in Zug, Switzerland and operations in San Francisco, Singapore, Hong Kong and Moscow.
