SERVICES
01
What we create is built to protect
Our services are crafted to turn confusing cryptography buzzwords into concrete and tangible security guarantees made with precision and rigor.
Security Auditing
Comprehensive security reviews for cryptographic protocols, smart contracts, and blockchain infrastructure.
Bespoke R&D
Custom research and implementation of cutting-edge cryptographic solutions for blockchain projects.
Concierge Advisory
Direct access to our team of cryptographers and researchers for ongoing support and consultation.
PROJECTS
02
Work that quietly speaks for itself
We shape each collaboration to make complex systems safer and simpler to trust.
Trusted by teams building with privacy and security in mind.
PROCESS
03
We guide every engagement through
uncertainty to confidence
From first scope to final verification, we bring structure, rigor, and accountability to every engagement.
Understand the System
We clarify the architecture, goals, and security assumptions before we begin
Do the Work
We audit critical paths, develop new components, and strengthen the parts that matter most.
Land the Outcome
We verify outcomes, document clearly, and support your team through launch and beyond.
Clarity before anything else
Answers to common questions about how we work and what to expect.
What does HashCloak specialize in?
HashCloak is a cryptography-focused R&D lab and security consultancy specializing in zero-knowledge systems, multi-party computation (MPC), threshold cryptography, secure key management, and blockchain protocol security.
Are you just auditors?
No. We are builders first. We design cryptographic systems, implement advanced primitives, integrate novel schemes into production environments, and audit them with the mindset of engineers who have built similar systems ourselves.
What kinds of audits do you perform?
Smart contract audits ZK circuit audits (Plonky2, Halo2, Noir, Circom, etc.) Protocol design audits Cryptographic primitive audits Governance mechanism reviews Bridging and interoperability audits VM-level audits
Do you audit zero-knowledge systems?
We provide full design and front-end development, including UI/UX, animations, and mobile responsiveness.
What does “Bespoke R&D” mean?
We involve you at every key step through reviews and feedback rounds to ensure the project stays aligned.
What cryptographic areas do you have expertise in?
We involve you at every key step through reviews and feedback rounds to ensure the project stays aligned.
