QHelm wraps institutional digital asset custody keys with NIST-standardized post-quantum encryption — deployable as middleware over your existing infrastructure, today.
Quantum is coming. If you are an institution, you’ll be expected to have a plan.
Every product wraps signing keys in the same NIST-standardized hybrid post-quantum construction — ML-KEM-768 + X25519, FIPS 203. Pick your coverage — Bitcoin-only with Keep, multichain with Aegis, or classified data and government systems with Warden. Add Argus when you want continuous monitoring across any of them.
Post-quantum protection for institutional Bitcoin keys. The lowest-friction upgrade any BTC custodian can deploy today on infrastructure they already operate.
Wraps the BTC private signing key in hybrid post-quantum cryptography (NIST FIPS 203 ML-KEM-768 + X25519) inside the custodian's existing HSM. No protocol change, no migration, no Bitcoin consensus required. Software middleware — connected via a single API.
Two-minute walkthrough of the post-quantum custody wrap for institutional Bitcoin holdings — and the same control plane catches today’s AI-era credential and supply-chain attacks.

QHelm wraps institutional Bitcoin custody keys with NIST-standardized post-quantum encryption — deployable as middleware over your existing infrastructure, today. The same construction that defeats tomorrow’s quantum adversary already defeats today’s AI-era attack surface: stolen credentials, supply-chain tampering, and insider exfiltration are all caught at the wrap layer. Post-quantum tomorrow. AI-era hardening today.

Post-quantum protection across every major digital asset. The omnichain answer for any custodian holding more than just Bitcoin.
Bitcoin, Ethereum and all EVM chains, Solana, Tron, plus major stablecoins — every signing key wrapped in the same hybrid post-quantum construction. One policy engine, one integration, one chain-agnostic cryptographic engine. Built on the same NIST standards as Keep, scaled to the full institutional digital-asset stack. Built to enterprise standards, the same engine also wraps healthcare records, legal-privileged archives, and other regulated long-lived secrets under vertical-specific compliance evidence packs.
A short walkthrough of post-quantum key protection across Ethereum, Solana, and multi-chain institutional portfolios — unified PQC coverage for every asset under management.
Post-quantum cryptographic guardian for classified data systems. The deployable answer for federal program offices, defense contractors, and government custodians facing NSM-10 migration mandates, CNSA 2.0 cutover (2027), and CMMC 2.0 compliance obligations on a tightening federal clock.
Hybrid post-quantum key wrapping deployed at the data-protection layer of classified and controlled-unclassified information systems. ML-KEM-768 + classical hybrid construction wrapped around the keys that protect documents, communications, and signing operations. Air-gapped deployment ready, FIPS 140-3 module validation on the roadmap, and aligned to NSM-10 NSS migration milestones and CMMC 2.0 / SP 800-171 r3 cryptographic controls. Designed for SCIFs and federal enclaves where harvest-now-decrypt-later is an active threat model.
A short walkthrough of post-quantum protection for classified and CUI environments — aligned to NSM-10, CNSA 2.0, and CMMC 2.0, engineered for air-gapped deployment and the FIPS 140-3 pathway.
AI-powered cryptographic threat detection layered over Keep or Aegis. The eyes that never close, watching what nobody else is watching: the cryptographic operations themselves.
Continuous AI behavioral baselines on every key-unwrap operation. Anomaly alerts forwarded to the customer's existing SIEM or SOC via webhook. Signed cryptographic attestation for every audit cycle. Software-only — never a managed service.
Argus is always sold as an add-on layer to Keep, Aegis, or Warden — never standalone.
A short walkthrough of AI-driven cryptographic threat detection — behavioral baselines per key, real-time anomaly alerts, and quantum-era visibility your existing SIEM was never built to see.
No protocol changes. No custody migration. No disruption to your existing infrastructure. Just quantum resistance — starting today.
Post-quantum cryptography (PQC) is a new generation of cryptographic algorithms designed to remain secure against a quantum computer. Bitcoin, Ethereum, and most digital infrastructure rely on elliptic-curve cryptography, which a sufficiently powerful quantum computer can break using Shor's algorithm. Because adversaries can record encrypted custody data today and decrypt it later once quantum computing matures — an attack pattern called harvest-now-decrypt-later — institutions can't wait for Q-Day to arrive before acting.
No. QHelm wraps the private keys you already manage inside your existing HSM or custody stack with an additional post-quantum layer. It connects via API in days, not quarters, and requires no re-custody event, no key rotation, and no changes to your existing operational tooling.
QHelm uses ML-KEM-768, standardized by NIST as FIPS 203 in August 2024 after an eight-year public evaluation process. QHelm pairs it with classical X25519 elliptic-curve key exchange in a hybrid construction, so a break of either the lattice-based or elliptic-curve math still leaves the other intact.
BIP-360 (P2QRH) is a proposed protocol-level upgrade to Bitcoin that would let new addresses use post-quantum signatures. It's an important long-term development, but it can't retroactively protect coins already sitting in exposed addresses, and it doesn't protect keys held in custody at rest today. QHelm closes that gap now — and QHelm-protected accounts are pre-staged to migrate automatically once BIP-360 lands.
One cryptographic engine, four surfaces. Keep is Bitcoin-only custody protection built for opt-in, customer-controlled deployment. Aegis extends the same engine across Bitcoin, Ethereum, Solana, and major stablecoins for institutional multichain custody. Warden is the government and defense surface, aligned to CNSA 2.0 and NSM-10 for classified and controlled-unclassified data. Argus is a monitoring layer that bolts onto any of the three, providing AI-driven anomaly detection and audit-grade logging.
Yes. QHelm gives custodians full control to suspend or reactivate protection at any time. The classical ECDSA layer remains fully intact throughout, so funds stay accessible regardless of the post-quantum wrapper's state.
QHelm Warden is built around the NSA's Commercial National Security Algorithm Suite 2.0 (CNSA 2.0), which requires ML-KEM and ML-DSA algorithms in national security systems, with deadlines beginning in 2027 and full cutover by 2035. Warden is designed for air-gapped deployment and tracks toward FIPS 140-3 module validation for federal procurement.
