Hey can someone help me...I am facing the same issues on windows as many are facing but unable to correct it. Shows the same error as everyone else here : ``` in sign_transaction raise TypeError( TypeError: from field must match key's 0x090dC592fDF4d7adB16CCCf15262335DE66eD316, but it was 0x7052b17De0ccc1De68437b03b197bF3057E45807 ``` This happened when i closed the ganache and terminal and when i came back to work on this project its showing this error Here is the whole deploy.py file ``` from solcx import compile_standard import json import os from web3 import Web3 from dotenv import load_dotenv load_dotenv() with open("./SimpleStorage.sol", 'r') as f: simple_storage_file = f.read() compiled_sol = compile_standard( { "language": "Solidity", "sources": {"SimpleStorage.sol": {"content": simple_storage_file}}, "settings": { "outputSelection": { "*": { "*": ["abi", "metadata", "evm.bytecode", "evm.bytecode.sourceMap"] } } }, } ) with open("compiled_code.json", "w") as f: json.dump(compiled_sol, f) # get bytecode # this is iterating through the compiled_sol.json and getting the bytecode bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["evm"]["bytecode"]["object"] # get abi abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"] #for connecting to ganache w3 = Web3(Web3.HTTPProvider("HTTP://127.0.0.1:7545")) # print(w3.eth.chain_id) # This is the chain id of the ganache network which returns 1337 chain_id = 1337 my_address = os.getenv("My_ADDRESS") private_key = os.getenv("MY_PRIVATE_KEY") # Create the contract in python SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode) print(SimpleStorage) # Get the latest transaction count i.e nonce value nonce = w3.eth.get_transaction_count(my_address) print(nonce) # Create the transaction transaction = SimpleStorage.constructor().build_transaction({"chainId": chain_id, "from": my_address, "nonce": nonce}) signed_txn = w3.eth.account.sign_transaction(transaction, private_key=private_key) # Send the raw transaction # tx_hash = w3.eth.send_raw_transaction(signed_txn.rawTransaction) # tx_reciept = w3.eth.wait_for_transaction_receipt(tx_hash) # working with the contract #for that we need contact address and ABI # simple_storage = w3.eth.contract(address=tx_reciept.contractAddress, abi=abi) # Call -> Simulate making the call and getting a return value # Transact -> Actually make a state change print(w3.eth.get_balance(my_address)) print(my_address) print(private_key) ``` And this is my .env file ``` export MY_ADDRESS ="0xb117deF084176e5Fdac7d979aa6524e3c8282049" export MY_PRIVATE_KEY ="0x31792fce4b6f6408398f3d73f8b2f438b44c515fffd576eee1766463ecdf7c93" ``` Help will be Appreciated !!
