Installation

From setup.py:

python setup.py install

Pip:

pip3 install coinaddrng

Usage

>>> import coinaddrng
>>> coinaddrng.validate('btc', b'1BoatSLRHtKNngkdXEeobR76b53LETtpyT')
ValidationResult(name='bitcoin', ticker='btc', address=b'1BoatSLRHtKNngkdXEeobR76b53LETtpyT', valid=True, network='main', is_extended=False, address_type='address')

ValidationResult returns coin name and ticker, address, if the address is valid or not. In case network prefix bytes are defined for the checked currency, then the network is returned, too. If the coin supports that and the address is an extended key, it returns if it is valid or not. For some coins the address type can be guessed based on its format, which is returned as address_type. If there's none, 'address' is being returned as a default.

Extending

Currencies

To add a new currency, simply instantiate a new coinaddr.currency.Currency class. It will be automatically registered.

from coinaddrng import Currency
Currency('decred', ticker='dcr', validator='DecredCheck',
        networks=dict(
            main=(0x073f,0x071a,0x02fda926), test=(0x0f21,0x0efc,0x043587d1)),
        address_types=dict(
            address=(0x073f,0x0f21), ticket=(0x071a,0x0efc),
            xpubkey=(0x02fda926,0x043587d1)))

To override a default currency, simply instantiate a new currency with that name.

Validators

To add a new validator, simply create a subclass of coinaddr.validation.ValidatorBase with your own implementation that implements the coinaddr.interfaces.IValidator interface. It will be automatically registered.

from zope.interface import implementer
from coinaddr.interfaces import IValidator
from coinaddr import ValidatorBase


@implementer(IValidator)
class NewValidator(ValidatorBase):
    name = 'New'

    @property
    def networks(self):
        return 'testing'

    def validate(self):
        return True

To override a default validator, simply create a new validator with that name.
