Zellic is a premier blockchain security firm specializing in smart contract auditing and vulnerability research. Founded by experienced security researchers with backgrounds in competitive hacking (CTF) and prior work at prestigious firms, Zellic has quickly established itself as a top-tier auditor in the Web3 space. Their client roster includes high-profile protocols across DeFi, NFTs, bridges, and Layer 1/Layer 2 ecosystems, lending significant credibility to their expertise.

Strengths include their deep technical bench, which spans EVM, Solana, Move-based chains, and zero-knowledge circuits — a breadth few competitors match. Their published vulnerability disclosures and research blog demonstrate genuine commitment to advancing blockchain security knowledge. The team's CTF pedigree translates well into adversarial thinking critical for audit work.

Concerns are relatively minor: the audit space is increasingly competitive, and as demand scales, maintaining consistent quality across engagements is always a challenge. Additionally, no audit firm can guarantee zero post-audit exploits. Overall, Zellic represents one of the strongest options available for projects seeking rigorous security review, and their reputation in the industry is well-earned.
