wallet.scan()

[g00day]

Do I have to call wallet.scan() after sending a transation to get unspent utxos?

You don't have to use the scan method, the utxo's will be included in wallet.

However they show up as unconfirmed. To see if your transaction is accepted by the network, and see how many confirmations it has, you have to use the scan or utxos_update method.

>>> from bitcoinlib.wallets import wallet_create_or_open
>>> w = wallet_create_or_open('bcl-testwallet', network='bitcoinlib_test')
>>> w.utxos_update()  # to get some test coins
2
>>> w.send_to('blt1qf3nktn0txwt5ue8800hxgzh29l98t6vh8c85jz', 10000000, broadcast=True)
<WalletTransaction(input_count=1, output_count=2, status=unconfirmed, network=bitcoinlib_test)>
>>> w.info()
