Django wallet for Bitcoin and other cryptocurrencies
Django-cryptocurrencies web wallet for Bitcoin and other cryptocurrencies.
Simple pluggable application inspired by django-bitcoin.
- Celery support
- Withdraw and Deposite
- 3 types of balances: balance, unconfirmed, holded
Edit Currency model
from cc.models import Currency currency = Currency.objects.create( label = 'Bitcoin', ticker = 'BTC', api_url = 'http://root:toor@localhost:8332' )
Start celery worker
$ celery worker -A tst.cel.app
Get new addresses for wallets
$ celery call cc.tasks.refill_addresses_queue
Now you can create wallets, deposite and withdraw funds
from cc.models import Wallet wallet = Wallet.objects.create( currency=currency ) wallet.get_address() wallet.withdraw_to_address('mvEnyQ9b9iTA11QMHAwSVtHUrtD4CTfiDB', Decimal('0.01'))
After creating a withdraw transaction you need to run
$ celery call cc.tasks.process_withdraw_transactions
Query for new deposite transactions:
If you want to catch event from bitcoind, but these calls options in bitcoin.conf file
walletnotify=~/env/bin/celery call cc.tasks.query_transaction --args='["BTC", "'%s'"]' blocknotify=~/env/bin/celery call cc.tasks.query_transactions --args='["BTC"]'
where "BTC" - ticker (short name) of the Currency
When you write applications that are working with money it is extremely important to use Database transactions. Currenly django-cc doesn't inclues any
@transaction.atomic. You should do this by yourself.
In my code I have a higher level wrapper with @transaction.atomic and to get wallets I'm always using select for update, like
Wallet.objects.select_for_update().get(addresses=address) to get a lock over the Wallet.
Supported crypto currencies
In general django-cc should work with most Bitcoin forks. I've tested it against: Bitcoin, Litecoin, Zcash (not anonymous transactions), Dogecoin and Dash.
When you are adding any other
Currency, than Bitcoin, you should define
dust values. Use tables below to get the values.
Magic bytes are used to verify withdraw addresses. They are different for each cryptocurrency
Minimal amount of valid transaction
Tests are written using Regtest. To run them you need docker and docker-compose. Simply run
docker-compose up and it will build and run all tests for you. Usually it takes about 5 min to run all the tests.
