## What is DeFi Market Making?
Decentralized Finance (DeFi) market making involves providing liquidity to decentralized exchanges and automatically executing trades to capture arbitrage opportunities. This requires real-time analysis of market conditions, optimization of liquidity positions, and risk management.

## Quick Start
<Steps>
<Step title="Install Package">
First, install the PraisonAI Agents package:
```bash
pip install praisonaiagents
```
</Step>
<Step title="Set API Key">
Set your OpenAI API key as an environment variable in your terminal:
```bash
export OPENAI_API_KEY=your_api_key_here
```
</Step>
<Step title="Create a file">
Create a new file `app.py` with the basic setup:
```python
