Our History

Cipher Safe Edge started in a cramped London workshop where three cryptographers grew uneasy with the state of crypto wallet security. They watched friend after friend lose bitcoin because a software wallet leaked keys to malware or a cloud service vanished overnight. Determined to build a safer path, they sketched a hardware device that would sign transactions inside a truly secure element, completely offline. Late‑night prototyping proved that an air‑gapped hardware wallet could keep crypto keys unreachable even by a fully compromised computer. That prototype signed its first bitcoin testnet transaction in the winter of 2018, and the concept immediately resonated with the local crypto community.

By 2020, the team had launched the first Cipher Safe Edge wallet at a bitcoin gathering in Manchester, where live demos won over early adopters. Penetration testers and secure hardware researchers helped harden the device, confirming that the hardware isolation could withstand real attacks. The small collective incorporated and moved into a permanent office on Old Gloucester Street, adding crypto firmware engineers and user‑experience specialists to the roster. They open‑sourced the full wallet firmware stack so anyone could audit the secure signing logic and verify there were no backdoors. Each bitcoin feature release was shaped by community feedback, transforming a passion project into a transparent, UK‑based hardware wallet brand. Today that restless spirit still drives every secure innovation, with thousands of crypto holders trusting Cipher Safe Edge to protect their bitcoin sovereignty.
