Ultimate Physical Isolation for
Cryptographic Keys
Jan Richters delivers robust physical hardware for offline data retention. Air-gapped, resilient, and completely isolated from digital networks. No Wi-Fi, no Bluetooth, no compromises.
Hardware Architecture by DMYTRO ROHACHEI KG
We manufacture physical security units. We do not participate in decentralized finance, investments, or crypto trading.
CC EAL6+ Secure Element
Our devices utilize military-grade secure element chips designed to withstand physical penetration, side-channel attacks, and fault injection.
True Air-Gapped Operation
No wireless modules exist on the motherboard. Data is transmitted purely via physical USB connection or optical QR codes.
Tamper-Evident Casing
The physical shell is ultrasonically welded. Any attempt to physically open the device results in visible destruction of the casing.

Frequently Asked Questions
Can I buy or trade crypto on your website?
No. DMYTRO ROHACHEI KG solely manufactures and sells physical hardware. We are not an exchange, broker, or financial institution. Our hardware does not have any trading APIs built in.
Does the device connect to the internet?
The hardware itself never connects to the internet. It acts as an isolated sandbox for signing data physically via USB.
Do you have access to my keys?
Absolutely not. The device generates the entropy locally. We only process your physical shipping address for logistics purposes.
