Why Do We Need Auditing?

Over the past three years, the Web3 ecosystem has experienced significant financial losses due to security breaches, underscoring the critical need for robust smart contract security audits.

2022: Escalating Threats

In 2022, the Web3 space witnessed approximately $3.7 billion in losses across various security incidents. This surge in attacks highlighted vulnerabilities in decentralized finance (DeFi) platforms and cross-chain bridges, emphasizing the necessity for comprehensive security measures.

2023: A Decline with Persistent Risks

The following year saw a decline in total losses to about $1.84 billion from 751 incidents, representing a 51% decrease compared to 2022. Despite this reduction, the average loss per incident remained substantial at $2.45 million. Notably, private key compromises accounted for nearly half of the financial losses, totaling $880.9 million in just 47 incidents. This period underscored that while overall losses decreased, significant risks persisted, particularly concerning private key security.

2024: Resurgence of Attacks

In 2024, the trend reversed with losses escalating to approximately $2.36 billion across 760 on-chain security incidents, marking a 31.6% increase in value stolen compared to 2023. Phishing attacks emerged as the most costly vector, responsible for $1.05 billion in losses over 296 incidents, accounting for nearly half of the total value stolen. Additionally, private key compromises resulted in $855.4 million in losses across 65 incidents. Ethereum remained the most targeted blockchain, experiencing 403 incidents that led to $748.7 million in losses.

The Imperative for Smart Contract Security Audits

These statistics from 2022 to 2024 highlight the evolving and persistent threats within the Web3 ecosystem. The substantial financial losses, particularly from phishing and private key compromises, demonstrate that malicious actors continually adapt their strategies to exploit vulnerabilities. Implementing rigorous smart contract security audits is essential to identify and mitigate these vulnerabilities proactively. Regular audits not only enhance the resilience of smart contracts against known attack vectors but also bolster investor confidence, contributing to the sustainable growth of decentralized technologies.

Multi Layer Audit Process

Things We Cover in the Audit Process :

We ensure your smart contract goes through all the stages, from manual code review to automated testing, before generating the Initial Audit Report. Once your team updates the code, we will thoroughly scrutinise the smart contract to provide you with the final audit report. Let's dive deep into the auditing process.

Step 1 - Specification Gathering / Prepare For a Security Audit

This is the most crucial stage because the details are key for a successful smart contract security audit. Here is how you can prepare for it:

Code quality • Remove dead code and comments. • Consistent coding style. • Follow the Solidity / Rust (Solana) style guide.

Use comments to document complex parts of the code and ensure these are consistent with the code.

Test the code • Make sure the contracts can be compiled and thoroughly tested. • Perform high coverage and high-quality unit tests.

This will maximize focus on the difficult parts of the code. Auditing should not discover that some functions are uncallable or do not do what they are expected to do under entirely straightforward inputs. Optimal auditing should focus on unexpected, corner-case, and adversarial behaviour.

Code freeze • Freeze the code and specify the commit hash. Or, deploy the code on testnet and share the link.

After freezing the code, we will gather the specifications from you to know the intended behaviour of the smart contract through the 'Smart Contract Specification' document.

<aside> 🦋 How you can help - Please ask your developers to fill out the specification doc - It would help us to understand & verify the business logic and facilitate confirming everything thoroughly.

Step 2 - Manual Review

Here we would look for undefined, unexpected behaviour and common security vulnerabilities. The goal is to get as many skilled eyes on contract code as possible. Aims of manual review:

Step 3 - Functional Testing

Step 4 - Formal Verification / Fuzzing*
