A sample file is provided: .env.example

Basic Usage

import os
from dotenv import load_dotenv
from hiero_sdk_python import Network, Client, CryptoGetAccountBalanceQuery, AccountId, PrivateKey

# Connect to testnet
load_dotenv()
network = Network("testnet")
client = Client(network)

operator_id = AccountId.from_string(os.getenv("OPERATOR_ID",""))
operator_key = PrivateKey.from_string(os.getenv("OPERATOR_KEY",""))

client.set_operator(operator_id, operator_key)

# Query account balance
balance = CryptoGetAccountBalanceQuery(account_id=operator_id).execute(client)
print(f"Balance: {balance.hbars} HBAR")
