Zellic Review — 5.0★ | Honest Verdict (2026)

Zellic is a premier blockchain security firm specializing in smart contract audits for Solana and other chains. Founded by veteran security researchers, Zellic has audited some of the most critical protocols in the Solana ecosystem including Wormhole, LayerZero, and Pyth Network. Their team combines deep expertise in Rust, the Solana runtime, and formal verification methods to uncover vulnerabilities that automated tools miss. Each audit includes a comprehensive report with severity ratings, proof-of-concept exploits, and remediation guidance. Zellic also contributes to the broader security community through open-source tooling and published research on Solana-specific attack vectors such as account confusion, missing signer checks, and PDA seed collisions. For teams building on Solana who need the highest assurance before mainnet deployment, Zellic provides the gold standard in manual security review.
