Signing Transactions with DPW VaultSign

Overview

This guide provides step-by-step instructions for securely signing and broadcasting cryptocurrency transactions using DPW VaultSign. DPW VaultSign implements an unbreachable transaction signing architecture with four-layer encryption, browser sandbox containment, and air-gapped broadcasting. Private keys exist only in volatile memory during millisecond signing windows, with immediate cryptographic erasure preventing persistent exposure. The air-gap design ensures that even with complete infrastructure compromise, attackers cannot autonomously broadcast transactions, requiring manual export for ultimate security.
