Before you choose

Requirements & limits

The project is open source under the AGPL-3.0 license. The README documents installation through PyPI, GitHub, or a source checkout.

  • Peth offers both an interactive command-line shell and a Python SDK.
  • The README demonstrates an Ethereum contract call using a contract address and either a method name or function signature.
  • The documented installation options include PyPI, GitHub, and a source checkout.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Peth from PyPI and open its shell

Install the Python package and start the documented Peth command-line shell.

Before you start

  • Python package installation with pip

Steps

  1. Run the command below.

    Documented command
    pip install peth

  2. Run peth to start the shell.

  3. Enter help in the shell to list documented commands.

Expected outcome

The Peth interactive shell opens and displays its command list when asked for help.

Guide limitations

  • This guide covers installation and opening the shell; it does not configure a chain connection or demonstrate a transaction.
