dazl: DA client library for Python

Dependencies¶

You will need Python 3.6 or later and a Digital Asset ledger implementation (DA Sandbox or DA Ledger Server).

Build-time dependencies are handled using Poetry.

Getting Started¶

This section assumes that you already have a running ledger with the standard daml new model loaded, and have imported dazl.

Connect to the ledger and submit a single command:

with dazl.simple_client('http://localhost:6865', 'Alice') as client:
    contract = { 'issuer' : 'Alice', 'owner' : 'Alice', 'name' : 'hello world!' }
    client.ready()
    client.submit_create('Main.Asset', contract)

Connect to the ledger as a single party, print all contracts, and close:

with dazl.simple_client('http://localhost:7600', 'Alice') as client:
    # wait for the ACS to be fully read
    client.ready()
    contract_dict = client.find_active('*')
print(contract_dict)

Connect to the ledger using asynchronous callbacks:

from dazl.model.reading import ReadyEvent
network = dazl.Network()
network.set_config(url='http://localhost:6865')

alice = network.aio_party('Alice')

@alice.ledger_ready()
async def onReady(event: ReadyEvent):
  contracts = await event.acs_find_one('Main.Asset')
  print(contracts)

network.run_until_complete()
