Keys¶

bitcash.Key¶: alias of PrivateKey

class bitcash.PrivateKey(wif=None, network='main')¶

This class represents a BitcoinCash private key. Key is an alias.

Parameters:: wif (str) – A private key serialized to the Wallet Import Format. If the argument is not supplied, a new private key will be created. The WIF compression flag will be adhered to, but the version byte is disregarded. Compression will be used by all new keys.
Raises:: TypeError – If wif is not a str.

property address¶: The public address you share with others to receive funds.

balance_as(currency)¶

Returns your balance as a formatted string in a particular currency.

Parameters:: currency (str) – One of the Supported Currencies.
Return type:: str

property cashtoken_address¶: The public address you share with others to receive cashtokens.

create_transaction(outputs, fee=None, leftover=None, combine=True, message=None, unspents=None, custom_pushdata=False)¶

Creates a signed P2PKH transaction.

Parameters:

outputs (list of tuple) – A sequence of outputs you wish to send in the form (destination, amount, currency). The amount can be either an int, float, or string as long as it is a valid input to decimal.Decimal. The currency must be supported. To send CashToken, the list of output is made in the form (destination, amount, currency, category_id, nft_capability, nft_commitment, token_amount). The category_id is hex of tx-id as str. The nft_capability is the capability of non-fungible token in (“none”, “mutable”, “minting”). The nft_commitment is the commitment of the non-fungible token in bytes. The CashToken property nft_capability, nft_commitment, or the token_amount can be None if not to be sent. If category_id is tx-id of unspent with tx-index 0, then tx is treated as a genesis tx.
fee (int) – The number of satoshi per byte to pay to miners. By default Bitcash will poll https://bitcoincashfees.earn.com and use a fee that will allow your transaction to be confirmed as soon as possible.
leftover (str) – The destination that will receive any change from the transaction. By default Bitcash will send any change to the same address you sent from.
combine (bool) – Whether or not Bitcash should use all available UTXOs to make future transactions smaller and therefore reduce fees. By default Bitcash will consolidate UTXOs.
message (str) – A message to include in the transaction. This will be stored in the blockchain forever. Due to size limits, each message will be stored in chunks of 220 bytes.
unspents (list of Unspent) – The UTXOs to use as the inputs. By default Bitcash will communicate with the blockchain itself.

Returns:

The signed transaction as hex.

Return type:

str
