Smart Contract Audit

Comprehensive security review and audit service to discover security vulnerabilities in smart contracts. Zokyo works line by line with your team to understand your project, then takes an adversary-focused approach to identify hidden errors, address design and logic issues, and identify security vulnerabilities before code goes into production or onto mainnet.

What's Included

The service includes a comprehensive line-by-line code review, automated and manual testing techniques (including advanced fuzzing), vulnerability assessment with severity ratings, comprehensive unit test development and coverage analysis, and an executive summary with high-level findings and recommendations. Zokyo's approach goes beyond just running code through automated tooling - they provide a proper security review rather than a rubber stamp.

Process

The audit follows a structured 8-step process: engagement and scope definition, documentation and preparation, comprehensive security review (including both static and dynamic analysis, mutation-based fuzzing, and property-based testing), vulnerability assessment with impact analysis, client review and mitigation guidance, verification of fixes through re-testing, final reporting with executive summary and technical documentation, and post-audit support.

Expertise

Zokyo's team identifies high-impact issues in 62% of security reviews and has audited over 1 million lines of code. They support multiple blockchain ecosystems including EVM, Move (Sui, Aptos), Cosmos, Avalanche, Solana, Filecoin, Sei, Conflux, and TON, working with projects built in Solidity, Move, Rust, and Go. The team employs advanced fuzzing frameworks to test smart contracts against millions of randomized inputs, discovering edge cases that are difficult to find through manual review alone.
