    'public_key': '03e8005aad74da5a053602f86e3151d4f3214937863a11299c960c28d3609c4775',
    'address': 'friday1r5v5srda7xfth3hn2s26txvrcrntldjuv7dedk'

Signing transactions

from hdacpy.transaction import Transaction
tx = Transaction(
        amount=amount, gas_price=2000000, fee=10000
res = tx.send_tx()

transfer() executes POST to organize tx, and send_tx() signs & broadcast the tx.
