This is the code repository for Hands-On Blockchain for Python Developers, published by Packt.
Empowering Python developers in the world of blockchain and smart contracts
We are living in the age of decentralized fi nance and NFTs. People swap tokens on Uniswap, borrow assets from Aave, send payments with stablecoins, trade art NFTs on OpenSea, and more. To build applications of this kind, you need to know how to write smart contracts.
This book covers the following exciting features:
- Understand blockchain and smart contracts
- Learn how to write smart contracts with Vyper
- Explore how to use the web3.py library and Ape Framework
- Discover related technologies such as Layer 2 and IPFS
- Gain a step-by-step guide to writing an automated market maker (AMM) decentralized exchange (DEX) smart contract
- Build innovative, interactive, and token-gated Web3 NFT applications

All of the code is organized into folders.
The code will look like the following:
from ape import accounts, project
import os
def main():
password = os.environ["MY_PASSWORD"]
dev = accounts.load("dev")
dev.set_autosign(True, passphrase=password)
contract = project.SimpleStorage.deploy(sender=dev)
num_value = contract.retrieve.call()
print(f"The num value is {num_value}")
Following is what you need for this book: This blockchain book is for developers interested in understanding blockchain and smart contracts. It is suitable for both technology enthusiasts looking to explore blockchain technology and programmers who aspire to become smart contract engineers. Basic knowledge of GNU/Linux and Python programming is mandatory to get started with this book.
