Basic examples

Create a wallet

from pystratis.nodes import StraxNode

node = StraxNode()

# Back up the mnemonic phrase, that's the only thing that could restore your wallet.
mnemonic = node.wallet.create(name='MyWallet', password='qwerty12345', passphrase='')

Send funds

from pystratis.nodes import StraxNode
from pystratis.core.networks import StraxMain
from pystratis.core.types import uint256, Money, Address
from pystratis.core import Outpoint, Recipient

node = StraxNode()

# Get first spendable transaction.
s_tx = node.wallet.spendable_transactions(wallet_name='MyWallet').transactions[0]

# Set our own address as recipient of change, use Money arithmetic for amount calculations.
recipient_self = Recipient(destinationAddress=s_tx.address, amount=s_tx.amount - Money(1.0),
                           subtraction_fee_from_amount=True)

recipient_another = Recipient(destinationAddress=Address('<another address>', network=StraxMain()), amount=Money(1.0),
                              subtractFeeFromAmount=False)

# Spend utxo from our transaction.
outpoint = Outpoint(transaction_id=s_tx.transaction_id, index=s_tx.index)

built_transaction = node.wallet.build_transaction(wallet_name='MyWallet', password='qwerty12345', outpoints=[outpoint],
                                                  recipients=[recipient_self, recipient_another], fee_type='high')

node.wallet.send_transaction(built_transaction.hex)
