Creating a transaction

import os

from mmisdk import CustodianFactory

# Instantiate the factory
factory = CustodianFactory()

# Grab your token from the environment, or anywhere else
token = os.environ["MMISDK_TOKEN_QREDO"]

# Create the custodian, using the factory
custodian = factory.create_for("qredo", token)

# Build tx details
tx_params = {
    "from": "0x62468FD916bF27A3b76d3de2e5280e53078e13E1",
    "to": "0x62468FD916bF27A3b76d3de2e5280e53078e13E1",

    # "maxFeePerGas": "12321321",
}
qredo_extra_params = {
    "chainID": "3",
}

# Create the tx from details and send it to the custodian
transaction = custodian.create_transaction(tx_params, qredo_extra_params)
print(type(transaction))
# <class 'mmisdk.common.transaction.Transaction'>

print(transaction)
