Tel Aviv, January 29, 2019SIRIN LABS, the creator of the world’s most secure blockchain smartphone, announces its most recent partnership with KoolSpan, the provider of TrustCall Secure Communications, enabling FINNEY users to protect their phone calls and chat and messages with secure and robust end-to-end encryption.

The SIRIN LABS-KoolSpan cooperation marks an important step towards global adoption of FINNEY as the world’s first and most secure blockchain smartphone. Consumers of FINNEY™ will have free use of the TrustCall Global Service until March 31st, 2019.

Telecommunications networks globally are vulnerable to monitoring and surveillance of phone calls and text messages at the hands of cyber criminals, corporate hackers, and nation states. These parties commit corporate espionage, steal intellectual property and sensitive financial information, monitor the calls and messages of targeted individuals, and compromise the privacy and security of people globally.

TrustCall by KoolSpan is the leading solution delivering end-to-end (E2E) encryption for phone calls and messages/chats. TrustCall delivers secure phone calls with high-definition audio through an easy to use and intuitive solution. TrustCall users can make secure phone calls that sound as good as regular, unsecure calls.

In addition, FINNEY users can invite their friends, family and colleagues to TrustCall, extending free utilization of the TrustCall Global Service until March 31st to others.

“We are thrilled to enter into a strategic partnership with KoolSpan,” says CEO of SIRIN LABS, Zvika Landau. “Together we are protecting FINNEY users from the leading cybersecurity threat to professional and personal communications.”

“KoolSpan is proud to partner with SIRIN LABS and the launch of the FINNEY, the world’s most secure blockchain phone,” says Nigel Jones, KoolSpan CEO. “This partnership is an important milestone towards providing more security and privacy for mobile devices and mobile communications for people everywhere.”


SIRIN LABS is developing the FINNEY™– the premier open source, ultra-secure blockchain smartphone with an embedded cold storage crypto wallet. Our vision is to bridge the gap between the blockchain economy and the mass market by solving the two greatest barriers to the crypto market: lack of both security and user experience. FINNEY™ will be running the SIRIN OS™, a Google-certified modification of Android, featuring SIRIN LABS’ proprietary cyber protection suite, wallet functionality, dCENTER (DApp store), and Token Conversion Service. SIRIN LABS has already established strategic partnerships with industry leaders like Cardano and FIH (Foxconn International Holdings– makers of the iPhone, Xbox, and Kindle), and has signed on the world’s greatest footballer, FC Barcelona’s Leo Messi, as official global brand ambassador for SIRIN OS™. Joining Messi as brand ambassador is the middleweight boxing champion, Gennady Golovkin, AKA “Triple G,” who is promoting the FINNEY™ Blockchain smartphone.
