Practical overview

When it fits

Use it when you are building a Python agent that needs to work with blockchain services and are prepared to assess each module's readiness and implement application-specific controls for any transaction-writing workflow.

Who it is for

  • Python developers building blockchain-interacting AI agents.
  • Teams prototyping DeFi, restaking, portfolio-tracking or cross-chain workflows.

Documented uses

  • Create an agent for a read-only balance check on Base.
  • Prototype agents for DeFi or restaking tasks.
  • Develop portfolio-tracking or bridging agent workflows.
Before you choose

Requirements & limits

The project is an open-source public repository under the MIT license. Python 3.10 or newer is listed as a requirement.

  • The quick-start example uses Base, a wallet key and an Anthropic API key.
  • The project describes itself as beta software; module readiness ranges from stable to experimental.
  • Write operations require a pre-sign gate, execution policy and application-specific authorization provider; a spend governor or confirmation prompt alone is not sufficient.

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

Set up a read-only balance-check agent on Base

Install the Python package and configure the documented quick-start flow to ask an agent to check balances on Base.

Before you start

  • Python 3.10 or newer
  • A wallet private key set as PRIVATE_KEY
  • An Anthropic API key set as ANTHROPIC_API_KEY

Steps

  1. Install the package with the command below.

    Documented command
    pip install web3-agent-kit

  2. Set the PRIVATE_KEY and ANTHROPIC_API_KEY environment variables.

  3. Create a ChainManager for Chain.BASE, load the wallet with Wallet.from_env, and create an Agent with the Uniswap tool.

  4. Run the documented prompt, Check my balances on Base.

Expected outcome

A read-only agent flow that returns the result of a Base balance check.

Guide limitations

  • This documented flow does not enable transaction signing or other write actions.
  • The project is beta software and module readiness varies.
