Crypto Cold Wallet Isolation

Cold wallet systems and crypto exchange infrastructure often require occasional interaction with online environments while still needing to keep private keys and signing systems isolated.

EtherGap provides real Layer 1 physical isolation between public network paths and cold wallet or exchange systems, keeping sensitive assets disconnected except during brief, controlled transaction windows.

When a transaction is required, the gap can be closed only long enough to complete the necessary exchange of data, then reopened to restore physical isolation.

This approach supports simple wallet environments, multi-signature systems, and larger exchange architectures where private keys must remain protected from continuous online exposure.
