Cyfrin - Top Smart Contract Audit Company

Press Release • May 3, 2023

The world of Decentralized Finance (DeFi) and blockchain technology is rapidly evolving, and with it come several security risks. As the industry matures, smart contract audits become increasingly important to ensure that projects run securely and efficiently.

Cyfrin is at the forefront of this new blockchain security wave by offering developers and investors smart contract audit services. With experienced and certified professionals on staff, Cyfrin guarantees secure, reliable audits backed by industry best practices.

In this article, we'll look into Cyfrin's ecosystem, mission, and the steps involved in a smart contract audit. Cyfrin’s core is the smart contract audit service, and the company’s offering also includes code reviewing and Web3 education.

What Is Cyfrin?

Cyfrin is a Web3 security company specializing in blockchain integrations, smart contract auditing, and educating developers. Their team is comprised of top competitive auditors, smart contract engineers who have written code that secures billions in DeFi, and have developed the most watched blockchain developer curriculum.

Cyfrin has provided smart contract security to many projects in the industry, as well as trained thousands of developers worldwide. They are committed to providing world-class protection and education for their partners and projects.

The Team Behind Cyfrin and Its Mission

The Cyfrin team consists of top engineers and auditors in the space. Each member brings a unique skill set to the table. For instance, we could mention Patrick's two FreeCodeCamp vides that have a combined ~5M views, and Hans's #1 ranking on Code4rena.

Furthermore, Alex is an ex-Chainlink Labs engineer with experience integrating billions of dollars worth of DeFi. 0Kage and Carlos are Code4rena's top finishers, while Giovanni has a strong smart contract development, fuzz & invariant testing, and also a competitive auditor.

By leveraging their expertise, Cyfrin strives to create a safe, reliable, and transparent environment in the Web3 and DeFi space.

Smart Contract Audits

Smart contract audits are incredibly important in ensuring the security of your blockchain-based protocol and digital assets.

By continuously auditing the code, businesses can stay ahead of attackers, always looking for vulnerabilities to exploit. Smart contract audits cover architecture design, coding standards, and security best practices.

Cyfrin is committed to helping businesses ensure the security of their protocols and digital assets through comprehensive audits. Cyfrin's team consists of experienced auditors with extensive knowledge of blockchain technology and smart contract development.

As a result, they can provide clients with an in-depth review of their codebase. These audits can also identify potential risks and suggest best practices to improve the security of their protocol.

Code Review

Code reviews are at the core of the software development process. Reviews allow developers to ensure that their code is working correctly and efficiently.

Code review is a great way to identify problems with the codebase early in the development process. Remember that these issues may become too difficult (or expensive) to fix as your project evolves.

Developers can spot potential bugs with a code review, explain how their code works, and suggest improvements. Code review ensures that your software development project is on track and cost-effective.

Fuzz Testing

When reviewing a code, Cyfrin leverages strategies such as fuzz testing to identify potential issues that can result in vulnerabilities.

Fuzz testing corresponds to a software testing technique providing invalid, unexpected, or random data as input to a computer program. Through this technique, Cyfrin helps developers identify hidden bugs, security flaws, and other problems with their codebase quickly and accurately.

Web3 Education

Cyfrin does not only do code reviews and smart contract audits. The company has recently taken an educational stance on Web3 technology.

Cyfrin’s CEO and Co-founder, Patrick Collins, has already produced two blockchain development courses on freeCodeCamp.org's YouTube page.

These courses range from topics such as the fundamentals of blockchain to building a smart contract in Solidity. Cyfrin plans to build upon this expertise and create an even larger portfolio of Web3 educational resources for users.

Through these efforts, Cyfrin strives to ensure users have the resources and knowledge needed to succeed in the DeFi/Web3 world. The company is working on launching the #1 Web3 developer education course. This plan intends to allow students to learn and master the technical aspects of blockchain development.

Subscribing to the project's education website is an easy way to stay up-to-date with the latest trends in Web3 technology.

How Does a Cyfrin Smart Contract Audit Work?

Cyfrin provides comprehensive smart contract audits to ensure the security of blockchain-based protocols and digital assets. Their process involves a 6 step approach, as outlined in the subsections below.

Step 1 - Price and Timeline

The Cyfrin smart contract audit process begins when a crypto team contacts the auditors. They discuss the audit's scope, which considers their code's complexity and size. Then they set a timeline and agree on a price for the audit.

The time allocated to the audit often depends on how many lines of code the professionals will need to examine. Prices for audits can vary depending on who is conducting them.

This phase is vital, as it helps establish a clear project understanding and ensures everyone is on the same page. This information creates an efficient process that can run effectively and efficiently.

Step 2 - Lock Commit Hash, Starting Date, and Downpayment

The second phase in Cyfrin's workflow is to lock the commit hash, starting date, and downpayment. All parties must agree on these details to start the audit process.

This ensures that all conclusions reached during the audit consider the same reference data set. These milestones make it possible to ensure the review of all aspects concerning the codebase.

This will help to provide an accurate and reliable analysis of the project. All parties' commitment allows for an efficient process with a successful conclusion.

Step 3 - Beginning of the Audit Process

Cyfrin's smart contract audit work can begin following the first two steps. The company's engineers will lead the project, spending their time and resources thoroughly analyzing your contracts.

Open communication is necessary to create a successful collaboration between Cyfrin and its partners. This ensures that everyone involved stays updated with the audit's progress and can address any potential concerns. With this effective partnership, Cyfrin will work to perform the audit with maximum efficiency.

Step 4 - Initial Report

Another essential milestone in Cyfrin's smart contract audit process is the initial report. This report overviews the findings and categorizes issues as High, Medium, Low, or Informational.

The findings always come with detailed explanations for further clarity. A call will then allow Cyfrin's engineers to ask questions about the results before fixing any identified problems.

Different findings require different actions depending on the severity of the issue. Issues categorized as High are considered critical and should be at the top of the engineers' to-do list.

Medium issues should also be looked into but may not require immediate action. Solving "Low" issues in later stages is often possible, as they do not pose a risk to smart contract operations. Lastly, Informational findings make users aware of potential risks so that they can take preventive measures.

Step 5 - Mitigation Phase

At this point, Cyfrin's smart contract audit workflow introduces the mitigation phase. Following the audit report's suggestions, project engineers can fix security vulnerabilities.

The mitigation steps may involve code updates and application architecture changes, with close collaboration between Cyfrin and the engineering team. This process helps ensure that the engineers address all remaining vulnerabilities before deployment.

Step 6 - Final Audit Report

The smart contract audit process ends with the final audit report. Engineers will check the mitigations and update the report as "Acknowledged" or "Resolved," along with additional relevant information if necessary.

Cyfrin will then sign off on the report, providing a comprehensive overview of all security issues. This step provides partners with peace of mind that their smart contracts have passed a thorough audit process.

Final Thoughts - A Platform Determined to Make the World of DeFi and Blockchain Safer

Cyfrin is a company that provides the most comprehensive smart contract audit solution. It strives to make the world of DeFi and blockchain safer by finding potential security risks in the codebase.

Through its thorough process, Cyfrin helps ensure that projects follow best practices to prevent common risks associated with smart contracts.

The need for secure, reliable smart contracts is only becoming more important as blockchain usage grows. Through Cyfrin's audit workflow, partners can have confidence in the security and accuracy of their projects.

Don't hesitate to reach out if you want to know more about Cyfrin and its smart contract audit process.

Cyfrin's website has a lot of useful information, including an FAQ page, contact forms, and more. The team’s GitHub page lists several public smart contract audits, showing potential clients Cyfrin’s quality and depth.

HyroTrader: Ranked Among the Best Crypto Prop Firms and Redefining the Industry Through Innovation and Scale

By Press Release • September 1, 2025

In the rapidly evolving world of trading, HyroTrader has emerged as one of the best crypto prop firms, setting new standards in transparency, technology, and community building. Founded in 2023 by entrepreneur Samuel Drnda, HyroTrader has grown from an ambitious idea into a global company with 34 full-time employees, a community of 30,000+ traders, and recognition across the industry as a true pioneer. From Startup Roots to Industry Leadership The HyroTrader story began with Samuel Drnda, a young entrepreneur who previously built and exited a company focused on automation, machine learning, and AI solutions, and also ran a performance marketing agency with over 40 employees. At just 24 years old, Drnda launched HyroTrade, a crypto CFD trading platform that attracted thousands of customers. During this time, Drnda also gained first-hand experience at Golem Trading, a traditional Prague-based prop trading firm. There, he realized something important: while forex traders had access to prop firms like FTMO, which generated more than $213 million in 2023, no equivalent solution existed for crypto traders. In 2023, Drnda pivoted the business into HyroTrader, an evaluation-based crypto prop firm built to provide traders with real opportunities to scale with capital, tools, and education. The First to Innovate: Bybit API Integration HyroTrader quickly made its mark by becoming the first crypto prop firm to introduce a direct API integration with Bybit. This innovation reshaped the industry, enabling traders to connect their accounts directly and trade in a way that had never been possible before. Other firms soon followed, adopting similar approaches, but the impact was clear: HyroTrader was setting the pace for the entire industry. “When we innovate, the industry follows,” says CEO Samuel Drnda. “We don’t just participate in this market — we move it forward.” Scaling Capital Access for Traders HyroTrader gives traders the ability to access funded accounts up to $200,000, profit splits of 70–90%, and the opportunity to scale up to $1 million in trading capital. So far, the firm has: Funded 700+ traders Processed more than $2 million in payouts Built a community of 30,000+ users worldwide This commitment has earned HyroTrader recognition in the industry, being ranked twice among the best crypto prop firms by respected outlets such as: Altfins: The Best Crypto Prop Trading Firms Living From Trading: Top Crypto Prop Firms Community and Global Presence HyroTrader is more than just a platform — it’s a global community. In late 2024, the company organized a trading tournament at Bybit HQ in Dubai, bringing together the top 30 crypto traders. The event went viral, generating over 170,000 views on social media and further boosting HyroTrader’s reputation as one of the most innovative names in the industry. Today, the team includes 34 full-time employees, with 15 in the Prague office and the rest working remotely from around the world. To support global growth, HyroTrader is also opening a new office in Dubai, a major hub for international crypto trading. Combating Fraud with Decentralization As the popularity of prop trading grows, so too has the number of fraudulent projects. HyroTrader is responding by building a decentralized crypto prop trading protocol, which will allow trader evaluations and performance to be recorded transparently on the blockchain. This innovation will provide traders with a verifiable trading history and give other firms the chance to build on the same framework, improving standards across the entire industry. Investing in People and Product Development HyroTrader is now entering its most ambitious growth phase yet. The company is hiring aggressively and investing heavily into product development to ensure its platform can scale efficiently. “By bringing in the best talent and building scalable technology, we’re preparing for the next stage — serving over a million traders worldwide,” explains Drnda. Future Roadmap Looking ahead, HyroTrader is preparing several major initiatives: New Scalable Application (2025): Launching a next-generation trading platform designed to scale operations to over 1 million users. Crypto Fund for Algo Traders: Supporting algorithmic traders with real capital, helping them test, validate, and scale their strategies. Expanding API Integrations: Partnering with multiple leading exchanges to bring prop trading to new markets. Exchanges themselves are showing strong interest, recognizing that the model generates substantial trading volume. A Trusted Name Among the Best Crypto Prop Firms With consistent innovation, industry-first integrations, and a clear vision for the future, HyroTrader continues to earn its reputation as one of the best crypto prop firms in the world. “HyroTrader was built to empower traders with real opportunities,” says Drnda. “From Bybit API integration to decentralized protocols, everything we do is about pushing the industry forward while protecting and supporting our community.” To learn more about HyroTrader or apply for a trading challenge, visit hyrotrader.com .

Vchat: Vietnam’s Awakening Answer to the Future of Social Networks

By press Release • September 1, 2025

In a digital landscape long dominated by Silicon Valley and China’s internet giants, a new force is rewriting the rules of connection and community: Vchat, a project born in Vietnam with a vision far larger than just another messaging app. What began as a communication tool has evolved into an awakening ecosystem — where ownership, governance, and value converge. Its mission is simple yet radical: return voice, value, and agency to the people. The Ownership Economy Unlike traditional social platforms that extract value from user data and attention, Vchat flips the model: Web3 Transparency – All contributions are recorded on-chain, ensuring fairness and traceability. AI Personalization – Each user interacts with an intelligent assistant that supports their journey. Community Rewards – Engagement is converted into VCT Tokens, turning participation into tangible ownership. At the heart of this system lies the VCT Token, powering Vchat’s digital economy. Every like, post, or contribution flows back into the community — not upward to corporations. Users can tip creators, unlock services, trade in the marketplace, or reinvest in the platform’s growth. Governance by the People Vchat is not run from boardrooms but by its community. Through DAO governance, users vote on features, economics, and rules of the ecosystem. Decisions once made in closed circles are now open, transparent, and democratic — a genuine shift of power from corporations to communities. Even advertising is reimagined. Instead of intrusive algorithms, Vchat introduces consensus-driven visibility, where creators and businesses gain exposure through community approval, not manipulation. Commerce Without Borders Beyond social interaction, Vchat embeds seamless borderless commerce. Users can buy, sell, and exchange digital goods or services directly through VCT — bypassing intermediaries. This creates a global marketplace where every participant is both a consumer and an entrepreneur. The VK Vision: From Vietnam, to the World Behind Vchat is VK, a founder whose philosophy goes beyond building platforms. As the Whitepaper states: “We are not chasing the attention economy. We are building the ownership economy — where communities don’t just participate, they lead.” This vision positions Vietnam not as a follower of digital trends, but as a producer of systems that can redefine global standards. Observers believe Vchat’s trajectory could mark a turning point not just for Vietnam’s tech landscape, but for the future of the internet itself. A Turning Point in Digital Culture Vchat is not competing for ad revenue or screen time. It is offering an entirely new paradigm: Where users are co-owners, not data points. Where technology empowers, not controls. Where value circulates within communities, not siphoned by corporations. As the project scales globally, it carries a bold message: “The future does not only begin in Silicon Valley. The future can begin anywhere — even here, in Vietnam.” Official Information Website: https://tapdoanvk.com Whitepaper: https://token.tapdoanvk.com
