CosmPy is a powerful Python library that allows you to connect and interact easily with Cosmos-based blockchain networks. Whether you’re looking to query account balances, transfer tokens, or dive into smart contracts, this guide will walk you through the process in a user-friendly manner.

Installation

To get started with CosmPy, you first need to install it. You can easily do this using pip. Open your terminal and run the following command:

bash
pip3 install cosmpy

Getting Started with CosmPy

Once you have installed CosmPy, you can start querying account balances. Here’s a simple example:

python
from cosmpy.aerial.client import LedgerClient, NetworkConfig

# Connect to Fetch.ai network using default parameters
ledger_client = LedgerClient(NetworkConfig.fetchai_mainnet())

# Specify the account address (in this case, Alice's address)
alice: str = "fetch12q5gw9l9d0yyq2th77x6pjsesczpsly8h5089x"

# Query all balances for the specified account
balances = ledger_client.query_bank_all_balances(alice)

# Show all coin balances
for coin in balances:
    print(f"{coin.amount} {coin.denom}")

Understanding the Code: An Analogy

Think of the code above as preparing a meal using ingredients from a recipe. Here’s how it all comes together:

• Connecting to the Network: When you create a LedgerClient, it’s like opening your kitchen door to the grocery store (in this case, the Fetch.ai network) to access all the ingredients (data) you need.
• Identifying Your Ingredients: The variable alice acts as the shopping list, specifying exactly which account’s balances you want to check.
• Fetching Data: By using query_bank_all_balances, you’re essentially asking the grocery clerk to fetch all the items on your shopping list – the balances, in this case.
• Viewing Your Ingredients: Finally, the loop that prints out each balance is like laying out all your ingredients on the counter, ready to be used in your meal!
