Hello @HalaAura The cytools error is pretty common amongst windows users, to solve this you have two alternatives:

As you reinstalled it the configurations are as the last time, so on settings change the gas Limit and gas cost to something higher, finally as this problems is taking this long to get solved I would like to know your Opinion @PatrickAlphaC, is may be something we are missing? |

Hi! I was having a similar problem except my main error message was: ValueError: {'message': "sender doesn't have enough funds to send tx. The upfront cost is: 7525300000000000 and the sender's account only has: 0" but when I tried to implement the code from @eehjunggnujhee I had another error message that read: ValueError: When using |

@karlMoreno Seems you are using SImpleStorage, uppercase which is wrong as it would take it as and object rather than an instance, please change your code to match the following: simple_storage = w3.eth.contract(address=tx_receipt.contractAddress, abi=abi)
print(f"Initial Stored Value {simple_storage.functions.retrieve().call()}")
greeting_transaction = simple_storage.functions.store(15).buildTransaction(
{
"chainId": chain_id,
"gasPrice": w3.eth.gas_price,
"from": my_address,
"nonce": nonce + 1,
}
) |
