Generating a wallet

from hdacpy.wallet import generate_wallet
wallet = generate_wallet()

The value assigned to wallet will be a dictionary just like:

{
    'private_key': '367360433d797cabd35361abdb3f6d0b94d27d7222d3af22a49028b7f4beb85d',
    'public_key': '0320a9b30c5fbbba3ffc34a1732c69365bc2a7de143f970318f8f1a2a38018dc6a',
    'address': 'friday1jg8n39n2m93aavjnxl7snnvt4q6n50g9alxgkl',
    'mnemonic': 'often day image remove film awful art satisfy stable honey provide cactus example flock vacuum adult cool install erase able pencil cancel retreat win'
}

Signing transactions

from hdacpy.transaction import Transaction
tx = Transaction(
        host="http://localhost:1317",
        privkey="26d167d549a4b2b66f766b0d3f2bdbe1cd92708818c338ff453abde316a2bd59",
        chain_id="friday-devtest",
    )
tx.transfer(
        token_contract_address="friday1lgharzgds89lpshr7q8kcmd2esnxkfpwmfgk32",
        sender_address="friday1lgharzgds89lpshr7q8kcmd2esnxkfpwmfgk32",
        recipient_address="friday1z47ev5u5ujmc7kwv49tut7raesg55tjyk2wvhd",
        amount=amount, gas_price=2000000, fee=10000
    )

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