The organization was best known for developing the first debit card technology to hold multiple cryptocurrencies blockchain assets.[1] Two founders of the company, Sam Sharma and Robert Farkas, were arrested on Sunday, April 1, 2018 with federal charges including securities fraud, conspiracy to commit securities fraud, wire fraud and conspiracy to commit wire fraud.[2]



Centra, found online at Centra.tech, is a cryptocurrency wallet linked with a debit card. You can use the debit card worldwide, which means you can spend your cryptocurrencies wherever cards are accepted.

In addition to the debit card and wallet, Centra is launching a platform called Coin Bay, which they’ve described as “the world’s first Amazon style superstore that is designed to be cryptocurrency acceptable.”

Centra has partnered with Visa, MasterCard, and a number of banks to allow them to issue cards worldwide. They officially support 100+ countries.
