ScaleBit

ScaleBit is a blockchain security team under BitsLab, specializing in smart-contract, DApp and full-chain architecture audits for the Bitcoin ecosystem and emerging chains such as Solana, ICP, Berachain and Monad. It serves protocol teams needing pre-launch and continuous protection, solving the difficulty of auditing novel components like ZK circuits, cross-chain messaging layers and Bitcoin L2s. Its method combines formal verification, fuzzing and expert review, and it built zkScanner to automatically scan zero-knowledge proof circuit source code, covering data flow, control flow and model checking.

In the ecosystem, ScaleBit sits as an emerging-chain security vendor, differing from general auditors by its specific accumulation in Bitcoin Layer 2, ZK and interoperability, with clients including Bitlayer, Merlin Chain and UniSat. Its services span contract audits, DApp audits, full-chain audits and vulnerability triage, and it participates in security programs of ecosystems like BNB Chain; as a BitsLab sub-brand it synergizes with academic output including several blockchain security papers, filling the supply gap on formal verification and circuit security for new chains.
