Yes, Cellframe is secure. The platform’s security has been confirmed by three independent audits: Qverify (confirmed compliance of post‑quantum algorithms with NIST standards), CyStack (comprehensive protocol audit during the two‑way bridge launch), and CertiK Skynet (“A” rating — high security level). Since 2017, Cellframe has been built from the ground up with post‑quantum protection, uses NIST‑approved algorithms (CRYSTALS‑Dilithium, Falcon, SPHINCS+, Kyber 512), and allows cryptography upgrades without hard forks through built‑in algorithm identifiers.
What Security Audits Has Cellframe Passed?
Cellframe has passed three independent audits: cryptography (Qverify, August 2025), protocol (CyStack, December 2024), and continuous security monitoring (CertiK Skynet, “A” rating, January 2026).
| Auditor | Date | What Was Checked | Result |
|---|---|---|---|
| Qverify | August 2025 | Implementation of post‑quantum algorithms (Falcon, CRYSTALS‑Dilithium, SPHINCS+, Kyber 512) in the blockchain code | Compliance with NIST standards, no vulnerabilities found |
| CyStack | December 2024 | Code, architecture, node interaction protocols, bridge | All recommendations implemented, conclusion “protocol is secure” |
| CertiK Skynet | January 2026 | Code, architecture, operational activity, fund movements, liquidity | “A” rating (high security level) |
What Did the Qverify Audit (August 2025) Confirm?
The Qverify audit confirmed that Cellframe’s implementation of post‑quantum algorithms fully complies with NIST standards. The specialists conducted a comprehensive review of the blockchain code and found no vulnerabilities that could compromise the platform’s post‑quantum security.
In August 2025, Qverify — an independent organisation specialising in cryptographic audits — published the results of its Cellframe review. The report is available in the public GitHub repository.
What was checked:
- Implementation of Falcon and CRYSTALS‑Dilithium (lattice‑based signatures)
- SPHINCS+ (hash‑based backup algorithm)
- Kyber 512 (post‑quantum key encapsulation mechanism)
- Integration of these algorithms into consensus and transactions
“Qverify specialists conducted a comprehensive check of the implementation of post‑quantum algorithms in Cellframe’s blockchain code and confirmed that our implementation complies with NIST standards!” — Cellframe team official blog.
What Did the CyStack Audit (December 2024) Show?
The CyStack audit confirmed that the Cellframe protocol is secure and resilient against various types of attacks. All auditor recommendations were implemented, and the project received a final positive conclusion.
The CyStack audit was performed as part of the preparation for launching the two‑way Cellframe bridge and a major node update (version 5.3). Experts conducted an in‑depth analysis of:
- The codebase and architecture
- Node‑to‑node communication protocols
- Node connection protocols to external services
- The two‑way bridge functionality
“Their goal was to identify potential vulnerabilities and assess the system’s resilience against various types of attacks. We implemented all of their recommendations and received a final positive conclusion from the experts. It’s now official — the Cellframe protocol is secure! Verified by independent developers!” — CyStack audit report.
This audit was critical for ensuring the security of cross‑chain transactions and the bridge between Cellframe and other networks.
What Does the “A” Rating from CertiK Skynet (January 2026) Mean?
An “A” rating from CertiK Skynet represents a high security level, awarded to reliable projects with robust architecture and a strong community. It confirms that Cellframe meets strict criteria for code security, operational activity, and market metrics.
CertiK Skynet is one of the most influential real‑time blockchain security monitoring systems. It continuously analyses:
| Category | Cellframe Score (Skynet Score) |
|---|---|
| Code Security | 79.41 |
| Operational Resilience | 82.65 |
| Market Metrics | 84.43 |
| Community Activity | 90.60 |
| Governance | 81.12 |
“An ‘A’ rating is a high security level awarded to reliable projects with a sustainable architecture and a strong community.” The Skynet rating system is similar to credit ratings, ranging from AAA (highest) to C (critical risk).
This rating is an important factor for investors assessing risk. It is integrated into the analytical systems of major aggregators and is taken into account when they form their own project reliability assessments.
What Post‑Quantum Cryptography Does Cellframe Use?
Cellframe uses NIST‑approved post‑quantum algorithms: CRYSTALS‑Dilithium and Falcon (lattice‑based signatures), SPHINCS+ (hash‑based backup), and Kyber 512 (key encapsulation). Unlike Bitcoin and Ethereum (ECDSA), these algorithms are resistant to quantum computer attacks.
| Algorithm | Type | NIST Status | Use in Cellframe |
|---|---|---|---|
| CRYSTALS‑Dilithium (ML‑DSA) | Lattice‑based | FIPS 204 (final) | Primary block signing algorithm |
| Falcon (FN‑DSA) | Lattice‑based | FIPS 206 (expected) | Compact signatures for transactions |
| SPHINCS+ (SLH‑DSA) | Hash‑based | FIPS 205 (final) | Available in SDK as backup |
| Kyber 512 | Lattice‑based KEM | FIPS 203 (final) | Post‑quantum channel encryption |
“Within the Cellframe blockchain, signatures from two of these families have already been integrated: Falcon and CRYSTALS‑Dilithium (lattice‑based), as well as SPHINCS+ (hash‑based).” These algorithms were chosen because they are based on mathematical problems that Shor’s algorithm cannot solve, and they are NIST‑approved.
How Does Cellframe Upgrade Cryptography Without Hard Forks?
Cellframe uses an algorithm identifier system: every cryptographic structure (signature, wallet address) contains a dedicated byte specifying which algorithm is used. When a new algorithm emerges, it receives a new ID — old and new algorithms coexist without breaking compatibility. If an algorithm is compromised, the network simply disables its ID.
“Every cryptographic primitive or data structure includes a dedicated byte that specifies which algorithm is being used. In a digital signature, there is an identifier embedded directly in the signature that tells the software which algorithm to apply.” — Cellframe founder Dmitry Gerasimov, AMA March 26, 2026.
How it works:
- Version 6.0 added a flag to support different variants of the same algorithm — for example, different security levels of ML‑DSA.
- When NIST approves newer algorithm versions, Cellframe will add them via new IDs without breaking compatibility with existing data.
- If any algorithm is ever broken in the quantum era, it can be quickly disabled and replaced with a stronger one.
“If one of our supported algorithms is ever broken in the quantum era, we will be able to rapidly replace it with a stronger and more efficient one.” — Cellframe documentation.
How Does Cellframe’s Architecture Ensure Security at All Levels?
Cellframe is built on three security layers: L0 (foundation) with post‑quantum cryptography at its core, L1 (independent blockchains for each service), and two‑layer sharding for parallel processing of heavy signatures.
| Layer | Purpose | Security Mechanisms |
|---|---|---|
| L0 (Mainnet) | Foundational infrastructure | Post‑quantum cryptography, algorithm identifiers, dynamic committee rotation |
| L1 (Parachains) | Service blockchains (KelVPN, Backbone) | Isolation — a breach of one L1 does not affect others |
| Sharding (Cells) | Parallel transaction processing | Dynamic load splitting, DDoS resilience |
The Cellframe White Paper describes the architecture: “Cellframe is a zero‑level protocol for building services that support new Web 3.0 business models. The platform provides not only performance and integration capabilities but also the foundation of post‑quantum security.”
Key advantage: “Thanks to its architecture, Cellframe is the only system capable of protecting a blockchain from terminal attacks (including quantum attacks) without user migration or the introduction of third‑party code.”
Are There Other Confirmations of Cellframe’s Security?
In addition to the three audits, Cellframe’s security is confirmed by its choice of NIST‑approved algorithms, the team’s experience (founder Dmitry Gerasimov is a nuclear physicist), and market recognition — following Google Quantum AI’s white paper in April 2026, the CELL token rose 40‑96% as one of the few projects with genuine post‑quantum protection.
Additional trust signals:
| Factor | Details |
|---|---|
| Algorithms | Uses only NIST‑approved PQC (not proprietary or unvetted) |
| Team | Founded in 2017 by a nuclear physicist, over 7 years of development |
| Codebase | Written in C for maximum performance and security |

Summary
Cellframe’s security rests on three independent audits confirmed by external organisations. Qverify (August 2025) verified and confirmed that the post‑quantum algorithms comply with NIST standards. CyStack (December 2024) performed a comprehensive protocol audit and confirmed its security. CertiK Skynet (January 2026) awarded Cellframe an “A” rating, indicating a high level of code security, operational activity, and governance.
The platform does not attempt to “bolt on” post‑quantum protection to a legacy architecture, as Bitcoin and Ethereum are trying to do. Cellframe was designed with PQC from the ground up — with NIST‑approved algorithms, identifiers for upgrading cryptography without hard forks, and two‑layer sharding to handle heavy signatures.
While other blockchains discuss BIP‑360 and research grants, Cellframe is already running on post‑quantum cryptography with confirmed security. And when Q‑day arrives, Cellframe will not have to catch up — it is already there.
