About MoveBit

Security experts specializing in the Move ecosystem, using formal verification to audit smart contracts on chains like Aptos and Sui.

MoveBit is a pioneering blockchain security team specializing in the Move ecosystem, a rising standard in secure smart contract development. As a sub-brand of BitsLab, MoveBit has become the most trusted name in Move-based security, working with developers, protocols, and platforms to eliminate risks and establish best practices. MoveBit is recognized for its deep technical expertise in formal verification and smart contract auditing for Move-based blockchains such as Aptos and Sui.


MoveBit’s mission is to deliver scalable, robust, and secure smart contract environments using the advanced capabilities of the Move language. With over 100 selected audits, a suite of proprietary developer tools, and academic publications in blockchain security, MoveBit continues to shape the future of Web3 security—one audit at a time.

MoveBit stands at the forefront of smart contract security for the Move programming language. Developed by BitsLab and supported by years of cybersecurity research, MoveBit provides full-stack auditing and verification services for Move smart contracts, dApps, and blockchain architectures. The Move ecosystem, led by chains like Aptos and Sui, introduces a new paradigm in secure on-chain development—and MoveBit ensures that this technology is deployed responsibly and securely.


From formal verification to static analysis and bytecode scanning, MoveBit leverages both manual expertise and automated systems to deliver audits with measurable impact. Teams that undergo MoveBit audits benefit from a comprehensive evaluation process including codebase examination, threat modeling, formal correctness checks, and real-time monitoring recommendations. This process ensures that applications are not only bug-free but also resilient to attacks and vulnerabilities that may emerge post-deployment.


MoveBit’s client list includes projects such as Merkle Trade, Amnis Finance, Cetus, SuiPad, Typus Finance, Scallop, Streamflow, and Aftermath Finance. By working with over 100 audited protocols, MoveBit has helped establish a security-first culture across the Move ecosystem. In addition to audits, MoveBit’s suite of developer tools—like the Aptos Move Analyzer, Sui Contract Source Verifier, and Move Web IDE—provides builders with security insights from day one.


The platform’s strength lies in its combination of academic research and real-world deployment. The MoveBit team has published over 20 peer-reviewed security papers and frequently hosts events such as MoveCTF and Aptos Builder’s Hours to engage and educate the global Move developer community.


As competitors like Trail of Bits, Consensys Diligence, and CertiK lead in general smart contract security, MoveBit takes the lead in Move-specific auditing. Its laser-focused approach gives it a strong competitive edge in securing one of the most rapidly growing ecosystems in Web3.

  • Step 3: After confirmation, the audit begins — combining manual review, formal verification, and automated analysis.
  • Step 4: Receive a detailed audit report outlining findings, threat levels, and actionable fixes.
  • Step 5: Apply the recommended fixes and submit your code for re-review.
  • Step 6: Receive a final, updated report and optional on-chain verification (if applicable).
  • Step 7: Engage MoveBit for ongoing monitoring, code updates, or additional audits as your protocol evolves.

MoveBit FAQ

  • MoveBit is fully specialized in the Move ecosystem, making it different from firms that audit across multiple languages without depth. As a sub-brand of BitsLab, MoveBit brings together formal verification techniques, academic research, and real-world audit execution — all specifically for Move-based blockchains like Aptos and Sui. It’s not just an auditing firm — it helps shape security standards for the Move language itself. Learn more at MoveBit.

  • Yes, auditing for Aptos and Sui is at the core of MoveBit’s services. Their tools and audit processes are optimized for Move smart contracts on these platforms. The team offers customized support, from static analysis and bytecode inspection to formal verification — ensuring each contract deployed on Aptos or Sui meets the highest security standards. Start an audit at MoveBit.

  • Formal verification is a method of mathematically proving that a smart contract behaves as intended, under all possible conditions. MoveBit uses this technique to ensure that vulnerabilities are not just caught — they're proven to be impossible. This approach gives developers and investors guarantees about the safety of their code, which is especially important in the Move language's resource-centric design.

  • MoveBit provides a suite of developer tools including the Move Web IDE, Aptos Move Analyzer, and Sui Contract Source Verifier to catch issues before audits even begin. These tools integrate with development environments like Visual Studio Code or work directly in browsers to assist with formatting, verifying, and testing contracts — enabling secure code from day one. Explore tools at MoveBit.

  • Yes. In addition to its industry-grade auditing services, MoveBit offers development tools, source verification platforms, IDE plugins, and long-term security monitoring. Products like the Move Scanner and Sui Move Analyzer provide static analysis and help detect issues at the bytecode level — giving teams actionable insights throughout their lifecycle.
