thirdweb AI v0.1 - Build Powerful Onchain Agents

Mar 18, 2025 • 2 min read

We're excited to announce the first release of thirdweb ai, a powerful Python library (TypeScript coming soon) that enables AI agents to interact with any EVM chains autonomously using thirdweb. This is a significant step forward in our mission to make web3 more accessible and empower developers to build the next generation of AI-powered onchain applications.

Why thirdweb ai?

As Large Language Models (LLMs) and AI Agents continue to evolve as transformative technologies, we recognized the need for these systems to interact with blockchain networks autonomously. We believe that giving AI agents the ability to perform onchain actions based on real-time data will unlock new possibilities.

What Can You Build?

With thirdweb ai, you can create AI agents that:

Manage wallets and transactions securely using Engine
Retrieve and analyze on-chain data in real-time using Insight
Delegate complex onchain executions to Nebula agents

All of this functionality integrates smoothly with the AI agent framework of your choice, including OpenAI Agents, LangChain, AgentKit, GOAT, AutoGen, LlamaIndex, and many more.

Getting Started

Installation

Install the core package with all adapters:

pip install "thirdweb-ai[all]"

Or choose specific framework adapters:

# For OpenAI Agents
pip install "thirdweb-ai[openai]"

# For LangChain
pip install "thirdweb-ai[langchain]"

# For AutoGen
pip install "thirdweb-ai[autogen]"

# For LlamaIndex
pip install "thirdweb-ai[llama-index]"

# For additional frameworks
pip install "thirdweb-ai[goat]"
pip install "thirdweb-ai[agentkit]"
pip install "thirdweb-ai[mcp]"
pip install "thirdweb-ai[smolagents]"
pip install "thirdweb-ai[pydantic-ai]"

See here for the full list of supported framework and installation guides.

Basic Usage

from thirdweb_ai import Engine, Insight, Nebula, Tool

# Initialize thirdweb services
insight = Insight(secret_key=...)
nebula = Nebula(secret_key=...)
engine = Engine(secret_key=..., engine_url=..., engine_auth_jwt=...)

# Get available tools
tools = [
    # Access powerful web3 tools
    # Optionally, select tool from each services
    *insight.get_tools(),  # Giving agents real-time on-chain data access
    *engine.get_tools(),   # Wallet and transaction management
    *nebula.get_tools(),   # Agent for complex blockchain tasks
]

Framework Integration Examples

OpenAI Agents

from thirdweb_ai import Tool
from thirdweb_ai.adapters.openai import get_openai_tools

# Initialize your thirdweb tools
tools = [...]  # List of thirdweb tools

# Convert to OpenAI tools
openai_tools = get_openai_tools(tools)

# Use in your OpenAI Agent
agent = Agent("thirdweb_agent", tools=openai_tools, ...)

LangChain

from thirdweb_ai import Tool
from thirdweb_ai.adapters.langchain import get_langchain_tools

# Initialize your thirdweb tools
tools = [...]  # List of thirdweb tools

# Convert to LangChain tools
langchain_tools = get_langchain_tools(tools)

# Use in your LangChain agent
agent = create_tool_calling_agent(tools=langchain_tools, ...)

Developer Resources

LLM Integration

When building applications that integrate LLMs with thirdweb's blockchain capabilities, you can enhance your results by including thirdweb context files:
