What ScaleBit does
ScaleBit is a blockchain security audit firm operating as a sub-brand of BitsLab, providing professional security services for smart contracts, decentralized applications (DApps), and full blockchain architectures. Founded in 2023 and headquartered in San Francisco with operating presence in Singapore and Hong Kong, the firm targets emerging Web3 ecosystems where traditional security firms have limited coverage, with specific focus on Bitcoin Layer 2 solutions, Zero-Knowledge Proof (ZKP) applications, and cross-chain interoperability protocols. Its customer base spans protocols such as Merlin Chain, bitSmiley, ZKFair, KiloEx, Manta Network, BEVM, and UniSat, with audits delivered through a structured seven-step engagement model spanning contact, evaluation and quotation, audit execution, report delivery, issue fixing, report updates, and ongoing monitoring.
The firm's core technology stack combines manual expert review with formal verification, fuzz testing, and proprietary automation. Its principal productized asset is zkScanner, an automated vulnerability scanner for ZKP circuits that supports Circom and Halo2 frameworks via data/control flow analysis and model checking, designed to identify under-constrained and over-constrained circuit issues. ScaleBit has also released an open-source Bitcoin Layer 2 Tapscript library implementing Taproot multisig cross-chain bridge primitives including single-leaf, multi-leaf, and MuSig2 signature schemes. ScaleBit organizes the BTC Security Lab consortium with BiHelix, Waterdrip Capital, Satoshi Lab, LK Venture, and Techub News, and hosts the Bitcoin Layer 2 Conference and zkCTF competitions to drive ecosystem engagement.
ScaleBit generates revenue through custom-priced, quote-based professional services engagements, with pricing not publicly disclosed and initiated via website contact form. The firm operates a B2B enterprise field sales motion targeting Web3 projects and blockchain protocols directly, supplemented by community and developer relations channels (Twitter, Telegram, Discord, WeChat, GitHub, technical blog, zkCTF competitions, and conferences). Distribution is global, with formal recognition in North America, Europe, and Asia-Pacific. The firm reports no external funding rounds, patents, certifications, or regulatory actions in the available data, and operates under the broader BitsLab umbrella alongside sister sub-brands MoveBit (Move ecosystem) and TonBit (TON ecosystem).
