The Hashlock Security Rating System
Our Blockchain audits are based on our consistent rating system, in which code is qualified based on its quality, vulnerability, future risk, and complexity. We advise that projects with a rating less than secure should not be deployed, and the Hashlocked rating is reserved for projects that value and invest in ongoing security efforts after the audit to protect their stakeholders.

Bridge Audit: Professional Smart Contract Security Audits by Hashlock
As Web3 continues to evolve and expand, bridges have become essential infrastructure, connecting different blockchains and allowing seamless interoperability. Think of them as the highways and byways of the decentralised world, allowing data and assets to flow freely between different networks.
But just as real-world bridges have long been used as strategic exploits in war, these digital connectors can also be vulnerable to attacks.
A faulty bridge can lead to catastrophic consequences, with malicious actors potentially disrupting traffic, stealing assets, or even bringing the entire structure tumbling down – not so dissimilar to cutting off supply lines and leaving military forces stranded.
This is why bridge smart contract security audits are such valuable resources. A bridge audit is like a thorough inspection conducted by experienced blockchain architects to make certain your bridge is structurally sound and secure from any potential threats.
This is a critical step in safeguarding your project and protecting your users’ assets. At Hashlock, we specialise in providing comprehensive bridge audits that give you peace of mind as your cross-chain connections are heavily fortified against any attack.
Understanding Bridge Smart Contract Security Audits
Bridge smart contract security audits are comprehensive solutions that go beyond standard smart contract audits. They carefully sound out the intricate mechanisms that allow different blockchains to communicate, examining the code, architecture, and security protocols that underpin these vital connections.
Let’s put it this way: a standard smart contract audit checks the individual components of a car, whereas a bridge audit scrutinises the entire transportation system; making sure all the roads, bridges, and traffic signals are working in harmony.
Why are bridge audits so important?
- Complexity
Bridges often involve complex interactions between multiple blockchains, thus making them a prime target for attackers. - High Value
Bridges often facilitate the transfer of significant amounts of value, making them highly attractive targets for theft. - Interoperability
A vulnerability in a bridge can have a ripple effect, impacting the security of connected blockchains.
A blockchain bridge audit from Hashlock will provide you with a comprehensive assessment of your bridge’s security, identifying any and all potential vulnerabilities and providing you with actionable recommendations for improvement
Our Comprehensive Bridge Audit Process
At Hashlock, we take a holistic approach to bridge audits, leaving no stone unturned in our mission to bolster your security. Here’s a quick glimpse into our comprehensive blockchain bridge audit process:
Extensive Manual Code Review
First, our expert auditors will diligently examine every line of your bridge’s codebase, making sure it adheres to best practices and is free from hidden vulnerabilities.
We will scrutinise the logic, structure, and functionality, leaving no room for error.
Vulnerability Analysis
We will employ a range of techniques to identify potential security weaknesses, including:
- Cross-chain vulnerability analysis
Identifying potential weaknesses in the communication protocols between blockchains. - Consensus mechanism analysis
Examining the mechanisms used to validate transactions and ensure consistency across different chains. - Cryptographic analysis
Evaluating the strength of the encryption and security protocols used to protect assets in transit.
Offensive Testing
Next, we’ll don our “ethical hacker” hats and simulate real-world attacks, assessing your bridge’s resilience against common threats such as:
- Replay attacks
Preventing attackers from reusing valid transactions to steal funds. - Double-spend attacks
Ensuring that assets cannot be spent twice on different chains. - Sybil attacks
Protecting against attackers creating multiple fake identities to manipulate the bridge’s consensus mechanism.
Development Revisions
We’ll then provide you with clear, concise feedback on any vulnerabilities we identify in our efforts, offering actionable recommendations for improvement.
No technical jargon or complex explanations – just straightforward advice you can use to strengthen your bridge’s security.
Final Analysis and Report
Once the necessary revisions have been made, we’ll then conduct a final analysis and provide you with a comprehensive audit report detailing all our findings, including:
- A summary of the identified vulnerabilities.
- An assessment of the severity of each vulnerability detailed in the report.
- Recommendations for immediate remediation.
- An overall security rating for your bridge.

Our bridge audit reports are valuable resources that provide expert insights and guidance for developers and the wider community. Here’s what you can expect:
- Detailed vulnerability analysis
We’ll clearly explain any identified vulnerabilities, their potential impact, and how to address them. - Project context and creation
We’ll provide an overview of your project, its goals, and the technologies used. - Risk assessments
We’ll assess the overall risk level of your bridge and provide recommendations for mitigation. - Industry research
We’ll incorporate relevant industry research and best practices into our analysis.
The Hashlock Security Rating System
To provide a clear and consistent assessment of security, we have our own, comprehensive rating system that we use in all our blockchain audits. Your code will be evaluated based on factors like:
- Code quality
How well-written and maintainable is your code? - Vulnerability severity
How serious are the identified vulnerabilities? - Future risk
Is your project susceptible to emerging threats - Complexity
How complex is your codebase, and does it increase the risk of vulnerabilities?
Based on this detailed assessment, we then assign a security rating to your project. Our highest rating is “Hashlocked,” signifying that your project has met our rigorous security standards and is ready for launch.
If your project receives a less than secure rating, then we strongly advise against launching until the necessary security updates can be made.
