qVAULT Opens Early Access for Post-Quantum Self-Custody on Hyperliquid

TLDR:

• qVAULT is the only live product letting Hyperliquid users store HYPE in post-quantum self-custody.
• Falcon (FN-DSA), a NIST-approved lattice-based scheme, powers all qVAULT transaction signatures.
• Harvest-now-decrypt-later attacks make every exposed on-chain ECDSA public key a current liability.
• qVAULT’s three-step migration moves assets from ECDSA control without requiring new technical skills.

qVAULT, a post-quantum self-custody vault developed by qLABS, has entered early access for Hyperliquid ecosystem holders.

The product uses Falcon (FN-DSA), a lattice-based signature scheme selected by NIST for post-quantum standardization.

It targets users holding HYPE and $qONE tokens, offering a migration path away from ECDSA-based custody. qLABS positions qVAULT as the only live solution allowing Hyperliquid users to store assets under post-quantum protection today.

Quantum Threats Already Affect Existing Blockchain Infrastructure

Major public blockchains, including Bitcoin and Ethereum, rely on elliptic-curve cryptography such as ECDSA, EdDSA, and Schnorr signatures.

Hyperliquid’s HyperEVM execution layer authenticates transactions using ECDSA over secp256k1, the same scheme Ethereum employs.

A sufficiently powerful quantum computer could break that cryptography, exposing any address whose public key has appeared on-chain.

The threat extends beyond future hardware. A “harvest now, decrypt later” model allows attackers to collect exposed public keys today.

Once quantum hardware matures, those keys can be decrypted retroactively. Every public key already on-chain carries that standing risk.

Hyperliquid amplifies this concern given its scale. The platform has processed over $3.5 trillion in cumulative trading volume and holds more than $9 billion in open interest. Its markets span crypto, commodities, indices, equities, and pre-IPO assets around the clock.

Every active position on Hyperliquid rests on an ECDSA key. That creates concentrated exposure precisely where institutional and retail capital is increasingly converging.

qVAULT Delivers a Three-Step Migration Into Post-Quantum Custody

qVAULT addresses the gap at the custody level, the part individual users control directly. It signs transactions with Falcon (FN-DSA), a compact lattice-based algorithm NIST selected under FIPS 206, currently in public review. qLABS never holds keys or seed phrases at any stage of the process.

The migration follows three steps. Users connect an existing wallet such as MetaMask, generate a post-quantum vault secured by Falcon signatures, then transfer assets into it.

The process moves holdings out of ECDSA-only control without requiring users to learn new technical frameworks.

Early-access participants who complete the migration qualify for qVAULT’s early-access rewards program. The product ships with a published litepaper covering its threat model, architecture, and Falcon integration, alongside completed independent security audits.

qVAULT’s technical advisory board includes Dr. Edoardo Persichetti, a co-author of HQC, another NIST-selected post-quantum algorithm, and Aaron Moore, former CTO of QuSecure and a veteran of the NSA and DARPA.

Andrew Cheung, CTO of qLABS, stated that the platform was built to convert years of industry debate into a product holders can use now.
