MoveBit

MoveBit is a security sub-brand of BitsLab focused on the Move ecosystem, auditing smart contracts, DApps and blockchain infrastructure on Sui and Aptos, with coverage running from contract code to whole-chain architecture. It addresses the novel vulnerability classes created by Move's resource model, generics and shared objects: audits use formal verification through the Move Prover and MSL to prove key invariants, paired with line-by-line manual review and fuzzing of edge cases. Its toolchain, including the Sui and Aptos Move Analyzers, Move Scanner and the Sui contract source verifier, turns audit findings into reusable detection rules for developers.

Within the Move ecosystem, MoveBit sits alongside the Sui and Aptos core teams as an audit partner, with public reports for major DeFi protocols and the MoveCTF security competition co-hosted with Sui. Unlike general EVM audit firms, it also maintains language tooling, pushing security rules into the coding stage.
