Similarityscan

Compare smart contract code and addresses to detect similar implementations, reused code, and potential contract clones.

Compare a contract address or source code against existing smart contracts to identify similar implementations, reused code, and potential contract clones. Similarityscan helps developers, researchers, and Web3 users quickly discover contracts that share similar source code. Find Similar Smart Contracts in Three Steps Smart contract transactions often display encoded method selectors rather than human-readable function names. Select the blockchain and enter a verified smart contract address, or paste the source code you want to analyse. The Similarityscan engine compares the submitted contract with existing smart contract sources and identifies matching or closely related code. View a list of contracts with similar source code and explore the results for further investigation. Detect Reused and Similar Smart Contract Code Smart contracts are often created by adapting existing code, using common templates or forking previously deployed protocols. While code reuse is common in Web3 development, understanding where code originated and how closely it resembles other contracts can provide useful context. Similarityscan allows you to compare a contract address or source code against existing smart contracts. The tool highlights similar implementations so you can investigate potential clones, reused components and shared contract structures. Why Use a Smart Contract Similarity Scanner? Discover whether a smart contract closely resembles contracts that have already been deployed. Use similarity results as an additional data point when researching unfamiliar tokens, protocols or blockchain projects. Find contracts that may share the same templates, libraries, functions or underlying architecture. Understand whether developers have reused existing source code and identify related contracts that may require further investigation. Quickly gather additional context before interacting with or reviewing a smart contract. Check whether your contract resembles existing deployments and review how similar implementations are structured. Discover related contracts and investigate whether vulnerabilities or risky patterns may appear across similar codebases. Gather additional information about a project's smart contracts as part of a broader due diligence process. Explore the origins and similarities of a contract before interacting with it. Monitor contracts that may reuse or replicate parts of your project's source code. Similar Code Does Not Always Mean Secure Code Similarity analysis can help you identify related contracts and reused implementations, but it does not provide a complete smart contract security assessment. Use Cyberscan AI to analyse your smart contract for vulnerabilities, risky logic and insecure implementation patterns. What is a smart contract similarity scanner? A smart contract similarity scanner compares a contract address or source code with other available smart contracts. It identifies contracts that share similar code, functions, structures or implementation patterns. What can smart contract similarity analysis detect? Does similar source code mean that a contract is fraudulent? Can Similarityscan detect smart contract vulnerabilities? Can I scan a smart contract address? Can I analyse source code that has not been deployed? Why is smart contract similarity analysis useful? Can two legitimate contracts have similar source code? Is Similarityscan a replacement for a smart contract audit? Identify vulnerabilities, review security findings and receive AI-powered remediation guidance with Cyberscan AI.
