The bitcoin payment processor launched Copay on the Windows app store Tuesday at the CES consumer electronics and technology tradeshow in Las Vegas.

The news follows the December announcement that Microsoft had begun accepting bitcoin through BitPay for select apps, games and video purchases.

Still in beta mode, Copay was initially developed for BitPay’s internal use, with its multisig functionality proving to be advantageous for corporate fund management and transactions requiring multiple authorizations, the company said.

Copay was released

as a security solution last year as demand for multisig technology increased.

Coinbase

Coinkite and Xapo are among other companies in the bitcoin space that have implemented multisig technology into their services.
