Decentralized Finance (DeFi) tools have revolutionized the way we interact with financial systems. The freedom to analyze and manipulate financial behavior through programming is both empowering and exciting! In this guide, we will walk through how to get started with DeFi open source tools and cover some core functionalities. Let’s dive in!

Installation

First things first, let’s get the tools set up. This can be achieved easily using pip, a package manager for Python.

pip install defi

General Tools

Once everything is installed, you can leverage various functions by importing the library.

Understanding Impermanent Loss

Consider two ice cream flavors in a cone, chocolate and vanilla. You want to see how much of each flavor you will lose if there’s a sudden spike in chocolate flavor sales (price increase). Through the `iloss` function, you can easily compute this:

import defi.defi_tools as dft
# Impermanent loss for stableCoin -20% return token
dft.iloss(0.8) # -0.62%
# Impermanent loss for stableCoin +60% return token
dft.iloss(1.6, numerical=True) # 2.7%

This analogy helps illustrate what happens to your asset value when market prices fluctuate, focusing on the concept of impermanent loss.

Comparing Buy & Hold with Staking and Farming Strategies

Just as you might measure returns from different cooking methods, you can evaluate returns from various DeFi strategies. The following function compares returns from buying and holding versus staking and liquidity farming:

# Simulating Returns
dft.compare(days=20, var_A=0, var_B=150, 
            rw_pool_A=0.01, rw_pool_B=0.05, 
            rw_pool_AB=0.2, fees_AB=0.01) 
# Example output: json buy_hold: 75.00%, stake: 75.60%, farm: 71.96%, Best: Stake

Exploring DeFi Protocols

To get essential information about various DeFi protocols like Uniswap, the following snippet provides an easy way to fetch metadata:

metadata, df = dft.getProtocol('Uniswap')
print(metadata) # Returns various details including id, name, address, etc.

Using APIs for DeFi Data

CoinGecko API

You can grab live data from the CoinGecko API to fetch token prices, exchanges, and historical data:

df = dft.geckoPrice('bitcoin', 'ethereum', 'usd', 'eur', 'brl')

PancakeSwap API

Just like a local market with live cabbage prices, you can check real-time token prices using PancakeSwap:

df = dft.pcsTokens()
print(df) # Returns a list of tokens and their prices

Troubleshooting

• Installation Issues: Ensure Python and pip are correctly set up in your environment. If you encounter version issues, try upgrading pip using pip install --upgrade pip.
• API Response Problems: If API requests fail, check your internet connection or verify if the API service is temporarily down.
• Code Errors: Review your code for syntax errors and ensure that the correct modules are imported.
