Ethereum smart contracts handle large amounts of value. It’s important to ensure that they are secure and free of vulnerabilities. Solidity audit tools can help identify potential security issues and vulnerabilities that may not be immediately apparent. This will ultimately help you build more secure smart contracts.
Solidity audit tools can help ensure that your code is of high quality and follows best practices. This makes it easier to maintain and modify your smart contracts. Plus, you will have improved performance.
Some industries and organizations may require that smart contracts be audited to ensure that they meet certain standards and requirements. Audit tools can help you to meet these requirements and demonstrate the quality and security of your smart contracts.
Here are the tools we recommend that you use when building smart contracts.
Slither
Slither is a tool for auditing and analyzing Solidity code. It can be used to find potential vulnerabilities and security issues in Ethereum smart contracts. Slither is designed to be easy to use. It can be run from the command line or integrated into a continuous integration (CI) workflow.
Slither performs a number of checks on Solidity code. Specifically, checks for common vulnerabilities such as reentrancy attacks, integer overflows, underflows, and function visibility issues. It also includes a number of checks for best practices. This ensures that all functions are properly documented and that variables are properly initialized.
Overall, Slither is a helpful tool for ensuring the security and correctness of Solidity code. It is a great tool that all developers should be using.
Mythril
Mythril uses a combination of static analysis, symbolic execution, and taint analysis to search for vulnerabilities in Solidity. It can find issues such as reentrancy attacks, integer overflows, underflows, and function visibility issues. Because it uses symbolic execution, Mythril can find security vulnerabilities that may not be caught by other analysis tools.
Mythril is easy to use and can be run from the command line or integrated into a continuous integration (CI) workflow. It is a helpful tool for ensuring the security and correctness of Solidity code. We recommend you use it in your project once your contracts are fully developed. It can take quite a while to execute!
Manticore
Manticore uses symbolic execution to analyze smart contracts. This allows it to explore all possible paths through the code and identify potential vulnerabilities. It can find issues such as reentrancy attacks, integer overflows, underflows, and function visibility issues, as well as other security vulnerabilities that may not be caught by other analysis tools.
Manticore is easy to use and can be run from the command line or integrated into a continuous integration (CI) workflow. It is a useful tool for ensuring the security and correctness of Solidity code, and it is recommended for anyone working with Ethereum smart contracts.
Echidna
Echidna is a tool for testing Ethereum smart contracts. It is designed to find vulnerabilities and security issues in Solidity code.
Echidna uses fuzz testing, which involves providing randomized input to a smart contract and observing its behavior. This can help identify issues such as integer overflows and underflows, unhandled exceptions, and other vulnerabilities that may not be caught by static analysis tools.
Echidna is easy to use and can be run from the command line or integrated into a continuous integration (CI) workflow. It is a helpful tool for ensuring the security and correctness of Solidity code, and it is recommended for anyone working with Ethereum smart contracts.
CryptoGuardian
CryptoGuardian is a platform that automatically audits your source code via a GitHub app. On every commit, CryptoGuardian will perform a full audit using the top open-source tools.
CryptoGuardian does the automatic setup of these tools for you. This can be a huge pain for many developers. These tools can be cumbersome to configure.
Remix IDE static analysis plug-in
The Remix IDE static analysis plug-in is a tool for analyzing Solidity code within the Remix Integrated Development Environment (IDE). It can be used to find potential vulnerabilities and security issues in Ethereum smart contracts, and it is designed to be easy to use and integrate with the Remix IDE.
The Remix IDE static analysis plug-in performs a number of checks on Solidity code, including checks for common vulnerabilities such as reentrancy attacks, integer overflows, underflows, and function visibility issues. It also includes a number of checks for best practices, such as ensuring that all functions are properly documented and that variables are properly initialized.
Overall, the Remix IDE static analysis plug-in is a useful tool for ensuring the security and correctness of Solidity code, and it is recommended for anyone working with Ethereum smart contracts in the Remix IDE.
Solhint
Solhint is a linter for Solidity code. It is designed to help developers write high-quality, secure, and maintainable smart contracts by checking the code for potential issues and suggesting best practices.
Solhint works by analyzing Solidity code and flagging any issues or potential problems it finds. This can include things like syntax errors, style issues, and security vulnerabilities such as reentrancy attacks or integer overflows. Solhint also includes a number of checks for best practices, such as ensuring that all functions are properly documented and that variables are correctly initialized.
Solhint is easy to use and can be run from the command line or integrated into a continuous integration (CI) workflow. It is a helpful tool for ensuring the quality and security of Solidity code, and it is recommended for anyone working with Ethereum smart contracts.
Should you use a Solidity audit tool?
Overall, using audit tools is an important part of the development process for Ethereum smart contracts, and it is recommended for anyone working with these types of contracts. Having programming knowledge outside of Solidity will help you be more effective with these audit tools. In particular, we recommend having a good grasp of JavaScript before you begin your Solidity journey.
