Fuzzing is an automated testing technique where we input a wide variety of random or specially crafted data into a contract to identify unexpected behaviors or vulnerabilities under different inputs. We specialize in fuzzing and have worked on various fuzzing strategies for different environments. For example, we have developed differential fuzzers for Solidity-based contracts, focusing on transaction scenarios to uncover critical denial of service issues. Our fuzzing efforts are aimed at ensuring contract robustness against unexpected inputs and behaviors, which can significantly enhance the security of the contract. Fuzzing can reveal hidden vulnerabilities that might not be found through other testing methods.

Formal verification employs rigorous mathematical methods and tools to ensure that a smart contract’s behavior conforms to its intended specification. This technique is particularly useful for high-security contracts, such as those involved in finance or user fund management. By using formal verification, we can mathematically prove that a contract behaves as expected under all possible conditions, preventing unexpected behavior or vulnerabilities. It provides a higher level of assurance that a contract is free from subtle bugs that might otherwise remain undetected through traditional testing methods. Formal verification is a powerful tool to guarantee that contracts meet their security and correctness requirements before deployment.

Penetration testing simulates real-world attack scenarios to assess the resilience of a contract under malicious conditions. We use advanced attack techniques and tools to simulate various types of attacks, such as reentrancy attacks, flash loan attacks, integer overflows, and others. Our goal is to evaluate how a contract responds to high-pressure situations and identify any potential weaknesses. Penetration testing not only focuses on the code itself but also examines the interactions with external systems, such as external calls and third-party integrations. This comprehensive testing helps us uncover vulnerabilities that might be exploited in real-world attacks, ensuring that the contract is robust and secure under various attack vectors.

Real-time monitoring is essential for identifying and responding to potential security threats after the contract is deployed. We offer dynamic security monitoring services that ensure the contract remains secure throughout its lifecycle. Our monitoring system continuously tracks all transactions and interactions with the contract, detecting abnormal behavior or suspicious activities, such as large transfers or frequent contract calls. This allows for immediate response to any potential threats, minimizing the risk of exploitation. We currently provide real-time security monitoring for contracts deployed on the Ethereum and Binance Smart Chain (BSC) networks, helping to ensure that projects can respond quickly to any emerging security issues.
