Why audit your smart contract with QuillAudits

A Cairo smart contract audit requires expertise in the Cairo programming language. QuillAudits Team deeply understand Cairo's unique features, such as its low-level architecture and strict typing system.


Importance of ZKSYNC Audit

Thorough Analysis of the Protocol
Thorough Analysis of the Protocol

QuillAudits ZKSYNC smart contract audit involves a comprehensive analysis of the ZKSYNC protocol, including its smart contracts, off-chain components, and zk-rollup architecture. The audit team should identify any potential security issues and provide recommendations for improving the protocol's functionality.

Security and Performance Testing
Security and Performance Testing

QuillAudits ZKSYNC audit process includes rigorous testing of the protocol's security and performance. This involves simulating various scenarios to identify potential vulnerabilities and ensure the protocol operates as intended.

A ZKSYNC smart contract audit is essential for ensuring the security and reliability of the protocol. QuillAudits thorough audit can help you identify vulnerabilities, ensuring that any bugs or security issues are fixed before deployment, reducing the risk of costly errors, and protecting the project's reputation.

Expert Team of ZkSync Auditors
Expert Team of ZkSync Auditors

A successful ZKSYNC smart contract audit requires an experienced team of auditors with a proven track record of auditing blockchain projects. QuillAudits team have a deep understanding of blockchain technology, experience with smart contract development, and expertise in zero-knowledge proofs.


Benefits of ZKSYNC Audit


Smart contract audits can help identify the code's potential vulnerabilities and security flaws, such as invalid inputs or malicious actors. ZKsync's use of zero-knowledge proofs (ZKPs) provides additional security measures, but it's still important to audit the smart contract code to ensure its robustness.


ZKsync's design allows for high-throughput and low-latency transactions, making it a promising solution for scaling Ethereum. A smart contract audit can ensure that the code is optimized for performance and can handle high volumes of transactions without compromising security or reliability.


ZKsync is designed to be compatible with existing Ethereum smart contracts, allowing developers to integrate it into their projects seamlessly. Smart contract audits ensure that the integration is done correctly and that the code interacts smoothly with other contracts on the Ethereum network.

Our Smart Contract Security Blueprint

ZKSync Protocol ComplianceVerify that the smart contract complies with the ZKSync protocol specifications and all related requirements.
Access ControlVerify that the contract properly restricts access to authorized users and that appropriate access control mechanisms are in place.
Input ValidationVerify that the contract validates input data to prevent malicious or unexpected input from causing errors or vulnerabilities.
Functionality and Logic FlawsCheck for logical flaws in the contract's functionality that may allow for unintended behaviours or exploitability.
Gas Usage OptimisationVerify that the contract optimizes its gas usage to prevent unnecessary consumption and fees on the Ethereum network.

A Comprehensive Look at Hacks and Scams in Web3

Each year, millions drain down the crypto hacks. Here are a few examples how hackers took advantage of the loopholes in the code to escape with millions:

In March 2022, $615M were stolen from Ronin Network, a platform powering the popular mobile game Axie Infinity.

In August 2021, the criminals transferred $611M-worth of Poly Network tokens to three wallets they controlled.

In September 2020, $275m worth of cryptocurrency was stolen from the Singapore-headquartered exchange KuCoin.
