What Hashlock does

Hashlock is an Australia-headquartered (Sydney) blockchain cybersecurity firm specializing in smart contract and protocol security auditing for Web3 projects. The firm delivers manual, competition-level line-by-line audits across 8+ smart contract languages (Solidity, Rust, Move, Go, Substrate, Cairo, Noir, CosmWasm) and 50+ blockchain platforms (Ethereum, Solana, Polkadot, Cosmos, Starknet, SUI, Aptos, Near), supplemented by penetration testing, formal verification, on-chain monitoring, incident response, and bug bounty program management. The company also offers a free AI-powered smart contract scanning tool (aiaudit.hashlock.com) as a product-led growth funnel, and has recently expanded into specialized verticals including RWA tokenization audits, Zero Knowledge audits, DePIN security, Bitcoin Layer 2/Ordinals audits, AI Software Audits, and Agentic Commerce Security, plus regulatory compliance services (VARA, DORA, Web3 KYC).

The business operates primarily on professional-services revenue from custom-quoted audit engagements, with pricing driven by codebase complexity, language, and platform. Go-to-market combines four motions: a direct-to-consumer "Request an Audit" website funnel with under-3-hour quote turnaround, product-led growth via the free AI Audit Tool, community-led engagement through bug bounty networks and Consensus Week events, and enterprise field sales targeting protocols holding billions in on-chain assets. The company has completed 500+ audits cumulatively, securing over $4B in on-chain value across customers including 1inch, Rocket Pool, SushiSwap, EigenLayer, Gala, Redbelly Network (sole security partner since 2023), Peaq, Energy Web, Algem, and Immersve. Approved-auditor relationships span BNB Chain, Polygon, Celo, Fantom, Quickswap, and the LF Decentralized Trust vendor directory.

Organizationally, Hashlock is a private company with 11-50 employees headquartered in Sydney. The company is a member of Blockchain Australia and FinTech Australia, and in April 2026 joined the Linux Foundation Decentralized Trust as a general member. It acquired StealthTest in December 2023. No parent company, funding rounds, or revenue figures are disclosed in available materials.
