We've successfully completed dozens of complex audits. Here're the reports for some of them.

tools
We contribute to the Web3 security by creating the tools that help to automate the security audit.
Reverse Engineering tool that helps you to efficiently match the function selectors in the EVM bytecode to the function signatures.
Smart diff tool that helps you to understand which code the protocol has been forked from and what exactly has been changed.
Semgrep Solidity rulepack helps developers to find the typical vulnerable patterns in the smart contract code in CI/CD.

Why Decurity?
We are a team of veteran hackers who dived into the blockchain and smart contract security in the early days. Under our supervision, an audit is not just a filing of the checklist but rather a full-fledged research.
