Smart contract auditing can support multiple file formats, depending on the programming languages and tools used in the development process. Commonly supported formats include:
Solidity (.sol) – The most widely used language for Ethereum smart contracts. Auditing tools like MythX, Slither, or custom scripts can analyze .sol files.
Example: A DeFi protocol's lending contract written in Solidity can be audited by parsing its .sol source code.
Vyper (.vy) – A Python-like language for Ethereum smart contracts. Some auditing tools support .vy files for security checks.
Example: A token contract written in Vyper can be reviewed for vulnerabilities.
Yul (.yul) – An intermediate language for Ethereum, often used for low-level optimizations. Auditors may analyze .yul files when reviewing compiled bytecode.
Example: A gas-efficient contract written in Yul can be checked for security flaws.
Bytecode (.bin/.hex) – Compiled smart contract bytecode (e.g., from Solidity or Vyper) can be analyzed using disassemblers like Etherscan or custom tools.
Example: Auditors may reverse-engineer a deployed contract's bytecode to identify potential issues.
ABI (Application Binary Interface) files – While not executable code, ABI files describe the contract's functions and events, aiding in functional audits.
Example: An auditor might use an ABI file to test a contract's interactions with external systems.
