Eight layers of protection. One device. Complete sovereignty.
CRYSTALS-Dilithium2/3/5 — the first hardware wallet shipping with NIST-approved lattice-based cryptography. Your assets stay safe even against Shor's algorithm.
NXP SE050 — the same tier used by governments and central banks.
Every signature requires a tactile press. Malware cannot simulate it.
Full-PCB coverage. Any intrusion → zeroization in <1 ms.
Bitcoin, Ethereum, BNB Smart Chain, Solana, CASH, and thousands more.
No drivers. No install. Plug in and sign from any modern browser.
No screen. No battery. No Bluetooth. No Wi-Fi. No NFC. No cloud. No accounts. No customer data stored. The device communicates only via USB-C — which can be physically severed.
The only hardware wallet with production post-quantum signing. Compared against every major competitor on the market.

We accept Bitcoin (BTC), Ethereum (ERC-20), and BNB Smart Chain (BEP-20). All transactions are verified on-chain. Your reservation is confirmed within 24 hours of payment.
KEY VERSION 1.0 is the only hardware wallet with production post-quantum signing (CRYSTALS-Dilithium). It is also the only device purpose-built for the CASH Transcendental Monetary Paradigm, with a full-PCB tamper mesh, EAL6+ Secure Element, and WebHID-native communication.
KEY VERSION 1.0 supports over 1,000 digital assets, including Bitcoin, Ethereum, BNB Smart Chain, Solana, CASH, and thousands of ERC-20 and BEP-20 tokens. Firmware updates continuously expand compatibility.
Reserve your units by filling out the form and sending the corresponding amount in BTC, ETH, or BNB to the provided address. Once your payment is confirmed on-chain, our team will contact you personally within 24 hours to confirm your order. Your units ship on a first-come, first-served basis.
Shipping begins in Q2 2027. Pre-sale reservations are fulfilled in the order they were received. You will receive a tracking number by email once your order dispatches.
Yes. The firmware and hardware design are fully open-source and auditable. The Secure Element firmware is closed by legal requirement (NDA-protected) but its interfaces are fully documented and independently verified by DeepSeek AI.
CASH is the native token of the CASH Transcendental Monetary Paradigm — a post-quantum, metaphysically-backed financial system. Every pre-sale unit comes with 10 CASH tokens as a founding participant bonus. These tokens will be distributed at mainnet launch.
Pre-sale reservations are refundable in full within 30 days of payment, minus blockchain transaction fees. After 30 days, reservations become non-refundable as manufacturing commitments are locked in.
