utxo – Chain 2 transactions in the same block with bitcoinlib in Python

utxo – Chain 2 transactions in the same block with bitcoinlib in Python

I asked yesterday if it is possible to have a tx from A to B and B to C in the same block. The second tx consumes the first UTXO (B’s initial balance is 0).

Apparently it is: Can two related “spends” be in the same block?

But now I’m trying to test this with bitcoinlib in Python. My code is:

wallet = Wallet.create('MyWallet',
                        keys = seed_phrase,
                        witness_type = "segwit")

address = wallet.get_key(0).address
address2 = wallet.get_key(1).address
address3 = wallet.get_key(2).address

wallet.transactions_update()

fee = 1_000
send_value = wallet.balance() - fee

tx = wallet.send( ((address2, send_value)),
                    fee = fee,
                    offline = True)

wallet.transaction_import(tx)

send_value2 = send_value - fee

tx2 = wallet.send( ((address3, send_value2)), 
                     account_id = 1,
                     fee = fee,
                     offline = True)

The first tx works fine since the first address has a balance, but the second address fails with:

WalletError: Create transaction: No unspent transaction outputs found or no key available for UTXO's

The problem seems to be getting the first tx for the wallet.

Any ideas on how to fix this? thank you
