Python SDK

Overview

If you want to use Python to connect with a blockchain node, it's possible to use vanilla Python but several convenience libraries exist within the ecosystem that make this much easier. With these libraries, developers can write intuitive, one-line methods to initialize JSON-RPC requests (under the hood) that interact with blockchain.

Python SDKs provide powerful and easy-to-use interfaces for interacting with EVM (Ethereum Virtual Machine) compatible blockchains like Ethereum, Polygon, BSC, Avalanche, and others.

Main Libraries:

1. Web3.py (Recommended)

• Official Python library for Ethereum

• Comprehensive API with extensive documentation

• Built-in support for smart contracts and transactions

• Active community and regular updates

2. Brownie

• Development framework built on Web3.py

• Integrated testing and deployment tools

• Smart contract compilation and management

• Great for DeFi and complex dApp development

3. Ape Framework

• Modern Python framework for Ethereum development

• Plugin-based architecture

• Advanced testing capabilities

• Type hints and modern Python features

Quick Example

Here's a simple example using Web3.py to check an account balance:

from web3 import Web3

# Connect to network (X1EcoChain Nubica Testnet)
w3 = Web3(Web3.HTTPProvider('https://nubica-rpc.x1eco.com'))

# Check connection
if w3.is_connected():
    print("Connected to X1EcoChain network")

    # Check X1 balance
    address = '<some address>'
    balance_wei = w3.eth.get_balance(address)

    # Convert from wei to X1
    balance_eth = w3.from_wei(balance_wei, 'ether')
    print(f"Balance: {balance_eth} X1")
else:
    print("Failed to connect")

Next Steps:

• Set up wallet connections and private key management

• Interact with smart contracts

• Handle transactions and events

• Implement error handling and gas optimization

• Use async/await for better performance
