What HashEx does
HashEx is a private blockchain security firm founded in 2017 and headquartered in Lewes, Delaware (HashEx US, LLC). Its core offering is smart contract security auditing for Web3 projects — comprehensive risk assessments of Solidity and Rust code on EVM and non-EVM networks, performed by teams of auditors using a stack that includes Solidity Compiler, static and dynamic analysis tools, Truffle/Ganache, Hardhat with ethers.js/waffle/mocha, and Echidna for fuzzing. The firm's process spans Contact, Quote, Audit, Report, Fixes, Recheck, and Publish, with a structural commitment to two independent manual review teams to reduce missed vulnerabilities.
Beyond audits, HashEx sells an expanding suite of adjacent services and products: a recurring Security Subscription with continuous monitoring, smart contract development, blockchain consulting, penetration testing, incident response, blockchain risk analysis, integration, HR, and marketing services for Web3 clients. It also distributes free developer tools (Auto Audits, Online ABI Encoder, Paper Wallet, Forkchecker) and operates the HashEx Academy, an education/certification platform for Solidity developers. A proprietary product, CryptEx, is positioned as add-on protection for blockchain projects.
HashEx goes to market sales-led via its website and Telegram, serving Web3 founders, DeFi protocols, NFT projects, and blockchain organizations globally. Marquee clients include ApeSwap, TraderJoe, SafeMoon, Venus Protocol, HurricaneSwap, Fringe Finance, and CronaSwap. Pricing is project-based (per-audit, customized by complexity, code volume, and urgency) with retainer revenue layering in via subscription. The company reports more than 1,500 audits completed and over $4 billion in assets safeguarded, is privately held by founders Dmitry Mishunin (CEO), Gleb Zykov (CTO), and Alexey Belozertsev (Lead Frontend & Backend), with Ksenia Borodulina as COO and Olga Ortega as Senior Product Manager, and discloses no institutional funding.
