Hi! How to send UTXOS to the address from which I sent the funds

[mccwdev]

Not sure if I understand your question fully, but here is an example on how to create a wallet and send a transaction.

from bitcoinlib.wallets import Wallet
w = Wallet.create('Wallet1')
key1 = w.get_key()
key1.address
'1Fo7STj6LdRhUuD1AiEsHpH65pXzraGJ9j'
# Now send a small transaction to your wallet and use the scan() method to update transactions and UTXO’s

w.scan()
w.info()  # Shows wallet information, keys, transactions and UTXO's
# When your wallet received a payment and has unspent transaction outputs, you can send bitcoins easily. If successful a transaction ID is returned

t = w.send_to('1PWXhWvUH3bcDWn6Fdq3xhMRPfxRXTjAi1', '0.001 BTC')
'b7feea5e7c79d4f6f343b5ca28fa2a1fcacfe9a2b7f44f3d2fd8d6c2d82c4078'
t.info()  # Shows transaction information and send results

in other words, how to disable change_keys in transaction_create() and send the remaining funds to my existing address (not gen new)

How to get address from imported wif to Wallet?

[SimpleFixOof]

Hey, could you please guide me on how to create a P2WPKH multiple input to single output transaction without using the wallet? What I don't understand is where do I get the witness, how is it formed? Because it seems that's what I'm missing. :)

You can find some examples in examples/transactions.py

This is an example which creates a transaction with multiple inputs signed with separate private keys:

print("\n=== Create and sign Testnet Transaction with Multiple INPUTS using keys from "
      "Wallet class 'TestNetWallet' example"
      "\nSee txid 82b48b128232256d1d5ce0c6ae7f7897f2b464d44456c25d7cf2be51626530d9 ===")
transaction_outputs = [Output(135000000, address='mkzpsGwaUU7rYzrDZZVXFne7dXEeo6Zpw2', network='testnet')]
t = Transaction(outputs=transaction_outputs, network='testnet')
