EVM

What is the EVM tool?

The EVM tool is a built-in capability in the Agno framework that allows AI agents to ethereum blockchain interaction and smart contracts. When added to an agent in Agno Builder, the agent can autonomously decide when to invoke this tool based on the user's request.

This tool requires a EVM_PRIVATE_KEY environment variable.

How to use EVM in Agno Builder

1. 1

   Create an agent

   Drag an Agent node onto the canvas in Agno Builder, or use one of the built-in templates.

2. 2

   Enable EVM

   Click the agent, go to the Tools tab, and toggle on "EVM" from the finance category.

3. 3

   Add your API key

   Enter your EVM_PRIVATE_KEY in the tool configuration. Your key stays in your browser and is never stored on our servers.

4. 4

   Test in chat

   Open the chat panel and send a message. The agent will automatically use EVM when relevant.

5. 5

   Export Python code

   Click File > Export Python to get clean, runnable code with the correct imports for EVM.

Python code example

This is the code Agno Builder exports when you use EVM:

from agno.agent import Agent
from agno.models.openai import OpenAIChat
from agno.tools.evm import EvmTools

agent = Agent(
    name="EVM Agent",
    model=OpenAIChat(id="gpt-4o"),
    tools=[EvmTools()],
    instructions=["Use the evm tool to help the user."],
    markdown=True,
)

agent.print_response("Help me with a evm task")

Install with: pip install agno # + set EVM_PRIVATE_KEY
