Blockchain Security

At the cybersecurity frontline of novel technologies.

Blockchain technology is on its path to confidently conquer more industries every day. As with any new technology, cybersecurity risks arise disproportionally. Hexens’ focus is to reorganize the security surface by providing state-of-the-art audits and research.

Smart Contract Audit
Prevent financial losses and exploitation of smart contracts and decentralized applications (dApps). Conduct the most thorough manual review of smart contracts code and logic, enhanced with static and dynamic analysis. The process is created to be relentless to all types of bugs, known and unknown. Smart contract audit includes not only finding and fixing critical bugs, but also inconsistencies with security standards and best practices, enforcing code quality.
Blockchain Audit
Blockchain being a fast-evolving technology with a variety of implementation designs is a wide attack surface. Blockchain audit is a state-of-the-art service with multi-level protocol analysis of: Consensus mechanism and Protocol design Cryptographic algorithms Network layer Application layer/Node security Economic flows The comprehensive audit reveals possible technological and economic attack vectors, introducing remediation strategies and cybersecurity solutions.
Cryptography Audit
Cryptographic services are not merely the mathematics of the algorithms used in cryptographic hardware and software solutions but also how these solutions are architected, developed, implemented, run, and audited within an organization's estate. We provide organizations with a variety of cryptographic auditing, advising, and delivery engagements to assist them in understanding how to adopt new solutions or verify the integrity of current cryptographic services.
Digital Asset Exchanges Audit
Digital Asset Exchanges fueled with large volumes of liquidity are one of the highest impact and common targets in the cryptocurrency ecosystem. Achieve a confident security posture through the full-scale audit process covering every aspect of digital asset exchange operations, such as: Infrastructure layer Web and Application layer Blockchain protocol layer Human factor
Hardware/Software Wallet Audit
Cryptocurrency Wallet solutions are commonly the final instance of digital asset ownership. Analyze and mitigate possible vulnerable flows, including but not limited to application security, cryptographic implementation and hardware vulnerabilities.

HERE ARE SOME OF THE HEXENS FREQUENTLY ASKED QUESTIONS

What is a smart contract audit?

Smart contract audit is the process of discovery and mitigation of critical vulnerabilities and other security flows in order to prevent fund theft and other financial losses.

How is a smart contract audit performed?

Smart contract audit is a multistage process, including static, dynamic and manual analysis of the code. The audit result is a report describing the vulnerabilities found and mitigation recommendations.

How long does a smart contract audit take?

The audit estimations are done on a per-project basis, please request a quote to get the exact time and price estimates.

What does an audit report include?

Smart contract audit includes the desired scope of work, the vulnerabilities and other security issues found, as well as the recommendations on how to fix them.

How much does an audit cost?

The audit estimations are done on a per-project basis, please request a quote to get the exact time and price estimates.

How often do I need to schedule security audits?

There is no strict schedule for audits. The rule of thumb is to undergo an audit before any production deployments.

What services does blockchain audit include?

Blockchain audit includes in-depth security analysis of the protocol, node and network layers.

What does a blockchain audit reveal?

Blockchain audit reveals vulnerabilities and other security issues in protocol layer, consensus mechanism as well as cryptography implementation and node application.

How long does a blockchain audit take?

The audit estimations are done on a per-project basis, please request a quote to get the exact time and price estimates.

What does a cryptography audit include?

Cryptography audit includes analysis of used schemes and implementations, revealing both theoretical and practical attack vectors and security considerations.

What aspects does a digital asset exchange audit cover?

Digital asset exchange audit covers all digital presence including web application and network infrastructure analysis, as well as blockchain level security considerations such as chain reorganization attacks.

What does a cryptocurrency wallet audit reveal?

Wallet audit reveals security weaknesses and vulnerabilities in the application including cryptographic and mathematical implementations.

Testimonials

Hexens is a hidden gem. Their attention to detail is unmatched. We started working with them for a single project to test them out but loved them so much that we gave them two more projects before the first engagement even got completed. They actually care about security and customer experience.

CISO @ Polygon Technology

I’d like to express my gratitude to the Hexens team for keeping the strict timelines, the quality of work, and the support provided throughout the remediation process. Many thanks once again!

Nikolaos Frestis

Senior Project Manager @ cLabs

The Lido DAO first approached Hexens when picking audit service providers for the Lido v2 upgrade – the most significant and complex yet. We were impressed with how the Hexens team provided a thorough code audit with meaningful findings while consistently meeting the ETAs. Many thanks to the team!

Gregory

Lido DAO

Report from H is the best reward for the hard work. As always, really appreciate the opportunity to work with @hexensio. Truly a professional team. Helped us to uncover several [far from obvious] attack scenarios.

Pavel Filippov

CTO @ RociFi

Thank you, Hexens.io, for being professional, responsive, and delivering a high-quality audit.

Burak Benligiray

Core Technical Team Lead @ API3

zkEVM is a new frontier, for this, we need security researchers that are willing to commit to learning while at the same time challenging what they learn. We feel confident with the audit work performed by Hexens. Thanks to the team for the professionalism and thoroughness.
