Smart Contracts Auditing
Our in-house team of security researchers performs comprehensive security audits, focusing on manual code reviews and extensive fuzz testing. Leveraging our battle-tested tooling, we ensure top-tier security. We offer both one-time audits and continuous auditing services to maintain robust security.
Security Tooling Development
Ackee security researchers develop security and developer tooling for Solana, Ethereum, and EVM blockchains. Leveraging our tooling, we have identified medium-to-critical vulnerabilities in industry leaders' smart contracts. We have received development grants from Coinbase and the Solana Foundation for building Wake and Trident, respectively.
Blockchain Security Education
Our team teaches about EVM and blockchain security at Czech Technical University, led by our co-founder and CEO, Josef Gattermayer, Ph.D. As educational partners of the Solana Foundation, we offer Rust and Solana development courses through our School of Solana.
Audits that keep you safe
Based on the internal statistics of 1442 days.
158 audits
Our experience and portfolio speaks for itself - trusted by industry leaders such as Safe, Lido and Axelar.
166 critical and high issues in 71 audits
We have discovered more than 1654 issues so far. 10% of them account for critical and high findings.
1 day to an issue
Our auditors discover a critical or high issue every 5 work days. It takes 2 work days to a critical, high, medium or low issue and 1 day to an issue in general, as of October 2024.
Our work & open source tools
Our mission is to make blockchain a safer space. To make it happen, we create security open source tools for developers and auditors.
