🔍Analyzing Smart Contracts Locally with Slither

Book an audit with Zokyo

Introduction

In this tutorial, we will guide you through the process of analyzing smart contracts locally using Slither. We will use a GitHub repository as a source of smart contracts to demonstrate the analysis process. Ensuring you have a well-structured approach to analyzing smart contracts will bolster your understanding and the efficiency of using Slither.

Prerequisites

Ensure you have the following tools and environments set up:

• GitHub (for cloning repositories)

• solc (Solidity Compiler)

• Slither and its dependencies installed in a virtual environment

• A code editor (e.g., VSCode)

Tutorial Steps

Step 1: Cloning a Repository

1. Navigate to the desired directory where you want to clone the repository.

2. Clone the repository using the following command:

   git clone [URL_OF_THE_REPOSITORY]

   Ensure you replace [URL_OF_THE_REPOSITORY] with the actual URL of the GitHub repository.

Step 2: Identifying the Contract for Analysis

1. Open the cloned repository in your preferred code editor.

2. Navigate through the repository and identify the smart contract you want to analyze. Take note of the path to this file, as it will be used in the next step.

Step 3: Setting Up the Virtual Environment

Ensure your virtual environment where Slither is installed is active. If not, navigate to your project directory and activate it:

• Windows:

  .\myenv\Scripts\activate

• Linux/Mac:

  source myenv/bin/activate

Step 4: Analyzing the Contract with Slither

1. In the terminal, ensure you are in the directory where the contract is located or use an absolute path to the contract.

2. Run Slither with the appropriate command and arguments, referencing the path to your smart contract:

   slither [PATH_TO_YOUR_CONTRACT]

   Replace [PATH_TO_YOUR_CONTRACT] with the actual path of the smart contract within the cloned repository.

3. Slither will execute, and the analysis results will be displayed in the terminal, outlining various aspects, such as vulnerabilities or code smells, based on the performed static analysis.

Conclusion

By following this tutorial, you have successfully cloned a GitHub repository, located a smart contract, and performed a local static analysis using Slither. This methodology ensures a systematic and efficient approach to analyzing smart contracts, leveraging the capabilities of Slither to identify potential vulnerabilities and areas of improvement in the contract's code. Remember always to conduct thorough and comprehensive analyses to uphold the security, performance, and reliability of your smart contracts.
