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.

Benefits of Solidity Auditing with Hashlock

Manual Security Research

Engaging in manual security research as part of the auditing process is a critical first benefit of using Hashlock for Solidity smart contract audits. This approach involves in-depth analysis by experienced professionals who scrutinize the code for vulnerabilities that automated tools might miss. They examine the contract's logic, compliance with best practices, and resilience against known attack vectors. This human element in the audit process helps in identifying subtle security flaws or logical errors, which are often overlooked by automated scanning tools. This ensures a more robust and secure smart contract, essential for maintaining trust and integrity in any blockchain-based system.

Comprehensive Vulnerability Detection

Hashlock's auditing process is designed to detect a wide range of vulnerabilities in Solidity smart contracts. This includes common issues like reentrancy attacks, overflow/underflow bugs, and gas limit vulnerabilities. The comprehensive nature of this detection process means that even the most sophisticated and hidden flaws can be identified. This thoroughness is vital in ensuring the security and reliability of smart contracts, as even a single overlooked vulnerability can lead to significant losses or breaches.

Contract Optimisation Suggestions

Beyond identifying security vulnerabilities, Hashlock also provides valuable insights into contract optimization. This involves suggesting improvements in the code that can enhance its efficiency, reduce transaction costs (gas fees), and improve execution speed. This aspect of the audit is particularly beneficial for developers looking to optimize their smart contracts for better performance and cost-effectiveness on the blockchain, thus making their applications more appealing and accessible to users.

Regular Updates and Post-Audit Support

Another significant benefit of using Hashlock for Solidity smart contract audits is the provision of regular updates and post-audit support. The blockchain ecosystem is dynamic, with new threats and best practices emerging regularly. Hashlock's auditing service includes updates in response to these changes, ensuring that the audited smart contracts remain secure over time. Additionally, post-audit support helps developers address any issues that arise after the audit, providing a safety net and ensuring long-term security and functionality of the smart contracts.
