I am encountering an issue with retrieving UTXO and balance values. Please help.

[kernaldpark]

The result of executing the following source code is a bit strange. The balance value is incorrect.

from bitcoinlib.transactions import Transaction from bitcoinlib.services.services import Service

addr_from = 'tb1q6v2tn4k7j9w5xxvwepkhdjrdpuwlwjcw3par5r' addr_to = 'tb1qrsjj80zgz2mat9h3mupce7tqcgqgycna6ywz6m'

utxos = Service(network='testnet').getutxos(addr_from) t = Transaction(network='testnet', fee=fee, witness_type='segwit') for utxo in utxos: t.add_input(utxo['txid'], utxo['output_n'], value=utxo['value'], witness_type='segwit') t.add_input(utxo['txid'], utxo['output_n'], value=utxo['value'], witness_type='legacy') value += utxo['value'] print(utxos)

output: (I tidied it up a bit to make it look nice.)

total balance: 569431

The precise total balance value is 566031. https://blockstream.info/testnet/address/tb1q6v2tn4k7j9w5xxvwepkhdjrdpuwlwjcw3par5r

The following source outputs the accurate balance value and UTXO.

from cryptos import *

timeout_seconds = 120 c = Bitcoin(testnet=True, timeout=timeout_seconds) addr_from = 'tb1q6v2tn4k7j9w5xxvwepkhdjrdpuwlwjcw3par5r' addr_to = 'tb1qrsjj80zgz2mat9h3mupce7tqcgqgycna6ywz6m' inputs = c.unspent(addr_from) print(inputs) balance = sum(list(map(lambda o: o['value'], inputs))) print('balance : %d' % balance)

output: balance : 566031
