QuillAudits

QuillAudits is a blockchain security firm specializing in smart contract audits and Web3 security assessments. Founded in 2018 as part of QuillHash Technologies by co-founders Preetam Rao (CEO) and Rajat Gahlot (CSO), the company grew from early supply chain blockchain projects with Tata Consultancy Services into one of the more widely deployed smart contract auditing providers in the Web3 industry, headquartered in Dubai, UAE. Smart contract vulnerabilities are permanent once deployed on-chain — attackers have an immutable target and stolen funds are typically unrecoverable. QuillAudits provides pre-deployment security reviews identifying vulnerabilities, logic errors, and economic attack vectors before code goes live, plus post-deployment monitoring to catch exploits in progress. The need for specialized auditors is particularly acute on Solana, where the account-based programming model, Rust ownership semantics, and Anchor framework abstractions introduce distinct vulnerability categories that differ from EVM contracts. QuillAudits structures audit engagements around a multi-layered framework: senior auditors conduct line-by-line manual code review with a separate lead auditor pass, the firm assigns 10-12 independent researchers per engagement for adversarial coverage, automated fuzzing tools including Echidna, Medusa, Foundry, and Chimera execute thousands of edge-case scenarios, and an internal Vigilant Squad performs independent validation to reduce false positives. Clients receive a full audit report with severity classifications, root-cause explanations, and remediation guidance, plus public audit certification and a leaderboard listing. For Solana specifically, QuillAudits targets six critical vulnerability classes: missing signer checks where programs must explicitly verify AccountInfo::is_signer; missing ownership checks requiring AccountInfo::owner validation; cross-program invocation depth limits under Solana runtime constraints; unsafe Rust code blocks bypassing memory safety guarantees; over-reliance on Anchor abstractions that can obscure logic gaps; and dependency management risks in third-party Anchor libraries. Publicly referenced Solana audits include Pluto Fi (liquidation logic and price feeds), Fly Trade v2 (reward optimization and liquidity integrity), Brahma Fi Console (access control), and Memeswap (vault vulnerabilities and DoS vectors). Beyond smart contract audits, QuillAudits provides penetration testing of dApps and APIs, wallet security audits covering key management flows, RWA and tokenization audits for real-world asset frameworks and stablecoins, post-exploit incident response, vCISO advisory for threat modeling, and on-chain monitoring with configurable event alerts. The firm also develops QuillShield, an AI-powered scanning tool using machine learning trained on historical exploit data, incorporating behavioral state analysis, semantic guard analysis for access control inconsistencies, state invariant detection for accounting desyncs, and oracle and flash loan attack analysis. QuillAudits covers 12+ blockchain networks: Ethereum, Solana, Polygon, Arbitrum, Optimism, Avalanche, Base, Binance Smart Chain, Sui, Aptos, StarkNet, zkSync, Linea, Near, Cosmos, and Fantom. Published figures as of 2025-2026 show 1,500+ protocols secured, 3B+ in TVL protected, 1M+ lines of code reviewed, 10,000+ issues identified, 2,000+ critical and high-severity vulnerabilities found, and an 80%+ client retention rate. Named clients include StarkWare, Taiko, ZetaChain, Metis, Magpie, and Covalent. Ecosystem partnerships span DeFi Security Alliance, Uniswap Foundation, Optimism Collective, and Polygon Security Partner Network. The firm audit reports are accepted by 50+ exchanges, which matters practically for Solana projects seeking exchange listings requiring third-party security certification. As Solana DeFi, RWA, and consumer application sectors have grown, QuillAudits' Solana-native audit service — covering Anchor-specific patterns, Rust unsafe code, and CPI depth issues — positions it as a security resource for projects building natively on Solana rather than migrating from EVM environments.
