PROVEN PROCESS
Our Audit Methodology for Privacy Protocols
We apply a specialized, multi-layered audit framework designed to secure the unique privacy guarantees and cryptographic integrity of stealth airdrop systems. Our methodology ensures your protocol's anonymity set remains robust and your user funds are protected.
01
Architecture & Cryptographic Review
Deep analysis of your protocol's privacy model, including nullifier schemes, stealth address generation (ERC-5564), and zero-knowledge proof integration. We verify the soundness of cryptographic assumptions and identify systemic risks.

02
Smart Contract Security Analysis
Comprehensive line-by-line review of all smart contracts (Solidity/Vyper) for vulnerabilities, focusing on access control, reentrancy in claim functions, and edge cases in fund distribution and withdrawal mechanisms.
