llamapay 0.1.0

ape-llamapay
Manage LlamaPay payment streams effortlessly from Ape Framework.
Quick Usage
You can use this SDK in ape console or in ape scripts. A short example:
from llamapay import Factory

factory = Factory()
factory.create_stream('banteg.eth', '1000 DAI/month', sender=accounts.load('dev'))

If deployment exists on the connected network, it will be automatically picked up.
A Factory is a registry and deployer of new pools. Each Pool manages all streams of a specific token. A Stream stores metadata like source, target, rate and allows operations on streams.
You can find pools by token address or symbol, courtesy of ape-tokens:
factory.pools
factory.create_pool('YFI')
factory.get_pool('DAI')

You can find streams from event logs and filter them by source or target, including their ENS names, courtesy of ape-ens:
pool.all_streams
pool.find_streams(source='ychad.eth')
pool.find_streams(target='wentokyo.eth')

To fund your streams you will need to deposit funds into a pool:
pool.get_balance('ychad.eth')
# infinite approve (optional)
pool.approve(sender=dev)
# auto approves the requested amount
pool.deposit('1000 DAI', sender=dev)
# withdraw all
pool.withdraw(sender=dev)
# withdraw some
pool.withdraw(Decimal('500'), sender=dev)

Token amounts can be specified as int for wei, Decimal for tokens, or str to be converted by ape-tokens based on their decimals.
It is easiest to prepare a stream from the Pool instance:
stream = pool.make_stream(source=dev, target=crush, rate='1000 DAI/month')

You can specify the rate as int for the internal 1e20 tokens per second representation or use a simple str format of amount symbol/duration like 1 YFI/week or 200,000 UNI/year.
Now that you have a Stream prepared, you can create it:
stream.create(sender=dev)
stream.pause(sender=dev)
stream.cancel(sender=dev)
stream.replace(new_stream, sender=dev)
stream.modify(target=new_crush, sender=dev)
stream.modify(rate=stream.rate * 2, sender=dev)
# check your withdrawable balance
stream.balance
# push tokens to recipient or withdraw them if you are one (these methods are the same)
stream.send(sender=dev)
stream.withdraw(sender=dev)
