About Us

Engineered in Britain to make self‑custody truly secure.

Cipher Safe Edge was founded in London by a team of cryptographic engineers and security auditors. We saw too many crypto users lose funds because their wallet relied on vulnerable software or cloud‑based key storage. Our mission is to build hardware that anchors trust in physical secure elements rather than blind faith in operating systems. Every device we ship creates an air‑gapped wallet environment where bitcoin transactions are signed without network exposure. We adhere to the strictest UK manufacturing standards and publish our wallet firmware for independent inspection. From our headquarters on Old Gloucester Street we serve individual crypto holders, family offices, and enterprises across Europe and beyond. Our commitment is simple: deliver a secure hardware experience that keeps your bitcoin permanently under your control.

We believe transparency is the foundation of secure custody. That is why our hardware wallet uses open‑source libraries that the global crypto community can audit at any time. Our engineers actively contribute to bitcoin improvement proposals and participate in wallet interoperability standards. We run a public bug‑bounty programme that rewards researchers who help us strengthen the secure signing pipeline. Every hardware revision is stress‑tested against side‑channel attacks, voltage glitching, and physical tampering. We do not hide behind proprietary secrecy; the only secret we protect is your private key. By choosing Cipher Safe Edge, you join a movement that demands verifiable secure crypto infrastructure. Together we can make bitcoin self‑custody the default, not the exception.
