Founded in May of 2016 by MIT graduates Sunil Aggarwal, James Gray, and Michael Wang, Clarium® is a digital Bitcoin wallet that is directly linked to a Visa card. We're based in Mountain View, California.

Bitcoin is the world's most widely used alternative currency with a total market cap of over $100 billion. Despite this, there are still only a handful of physical merchants who directly accept Bitcoin as a form of payment.


By connecting Bitcoin holdings directly to a user's Visa card, the user can spend fiat currency like any other Visa card, with the fiat currency amount spent converted in real time  and shown as an equivalent Bitcoin debit transaction in the user's Bitcoin wallet,

We also encourage our clients to use Clarium® as their primary Bitcoin wallet, irrespective of our Visa add-on. We provide bullet-proof offline protection, with our date split with redundancy, then AES-256 encrypted, and finally copied to FIPS-140 USB drives and paper backups. Darnley Mining - Bitcoin Miners
