Edit: Never mind I found the problem. It was the code I wrote that was wrong.
I am running into an error eth_signTransaction not supported which stops me from trying to make a transaction.
I was running this on VS code python web3.py.
So, I was following the freecampcode video on Solidity(The 16 hours).
How do I fix this
I followed as the video suggested and got stuck on when trying to use web3 with ganache(the user interface one, not the command prompt version).
Thank you in advance.
This is the code
w3 = Web3(Web3.HTTPProvider("http://127.0.0.1:8545"))
chain_id = 1337
my_address = "0x83C00C2cA9c05c448C5f88e28F5146Fc83d236bD"
private_key = os.getenv("PRIVATE_KEY")
# Create the contract in python
SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
# Get the latest transaction
nonce = w3.eth.getTransactionCount(my_address)
# 1. Build a transaction
# 2. Sign a transaction
# 3. Send a transaction
transaction = SimpleStorage.constructor().buildTransaction(
{
"gasPrice": w3.eth.gas_price,
"chainId": chain_id,
"from": my_address,
"nonce": nonce,
}
)
#problem start here
sign_txn = w3.eth.sign_transaction(transaction, private_key)
tx_hash = w3.eth.send_raw_transaction(sign_txn)
This is the error message
