Product Introduction
- Overview: Frozen Security is a Physical Private Key System and signing architecture that merges the durability of seed backup plates with the functionality of a hardware wallet. It is categorized as a high-assurance cold storage solution for digital assets.
- Value: It eliminates the 'digital key at rest' vulnerability common in hardware wallets by using a physical titanium plate to derive keys only during the moment of signing, ensuring no digital footprint exists between transactions.
Main Features
- Grade 5 Titanium Encoding: The private key is physically encoded onto a titanium plate rather than a silicon chip, making it immune to electronic probing, firmware hacks, or battery failure.
- Isolated Dual-MCU Architecture: The system utilizes two hardware-isolated microcontrollers—an NFC MCU for smartphone communication and a Signing MCU for key derivation. This physical disconnect ensures that even a compromised communication layer cannot access the key.
- Volatile Memory Derivation: Keys are derived in volatile memory only when the plate is inserted and are instantly cleared once the transaction is signed, following the 'Insert. Sign. Done.' workflow.
Problems Solved
- Challenge: Physical extraction of digital seeds from hardware wallet chips using low-cost side-channel attacks.
- Audience: Crypto investors, institutional custodians, and long-term HODLers seeking maximum self-custody security.
- Scenario: A user needs to sign a high-value transaction without exposing their seed phrase to an internet-connected device or a permanent digital storage medium.
Unique Advantages
- Vs Competitors: Unlike traditional hardware wallets (which store keys digitally) or seed plates (which cannot sign), Frozen provides a single object that acts as both the authority and the execution tool.
- Innovation: Protected by US Patent Application 2026/0039478 A1, the architecture ensures zero digital persistence and high interoperability using the industry-standard BIP-39 protocol.
Frequently Asked Questions (FAQ)
- How does Frozen Security differ from a standard hardware wallet? Standard hardware wallets protect a digital key that always exists on a chip; Frozen uses a physical titanium plate to derive the key only during the signing process, leaving no digital key at rest.
- What happens if I lose the titanium plate? Since the plate encodes a standard BIP-39 seed phrase, you can restore your funds using any compatible recovery tool, though the physical plate itself is required for the Frozen signing workflow.
- Does Frozen Security require a battery or firmware updates? No. The titanium plate is a passive physical object with no electronics, meaning there is no battery to die and no firmware on the key itself that requires patching.
