A minimalistic any coin (Bitcoin, Litecoin, Dogecoin..) RPC client and utilities for Python 3.

• Tiny
• Easy to review
• Free and open source (GPLv3)
• No external dependencies
• No API breaking changes in horizon

It allows you to build Python programs that

• Talk with the Core Wallet's RPC server (TinyCoinTalk @ talk.py)
• Receive coin payments (TinyCoinReceive @ receive.py)
• Make coin payments (TinyCoinSend @ send.py)

Warning! TinyCoinLib comes without any warranty. Improper use or software bugs can lead to loss of coins. Run only on trusted platforms. Proceed at your own risk.

Warning! TinyCoinLib is in early development and not production ready yet. Its features remain mainly untested. This will change in future revisions.

Warning! Pre-release versions (v.0.0.Z) are completely untested. Functionality is likely broken.

First, install TinyCoinLib form the Python Package Index

pip install tinycoinlib

Next, download the Core Wallet from a trusted source and verify its integrity (checksums and signature). Start the bundled coind program (bitcoind, litecoind, dogecoind, ...) and wait for the blockchain to synchronise.

Then you are ready to go.

from tinycoinlib.talk import TinyCoinTalk

talker = TinyCoinTalk('litecoin')
response = talker.call('getblockhash 69')

The constructor takes a URL as its first parameter. It points to the {}coind RPC server or is a special value listed in the PRESET_PORTS dictionary.

The call method takes in a command and returns the server's response.

from tinycoinlib.receive import TinyCoinReceive

receiver = TinyCoinReceive('127.0.0.1:18933')
trans_id = 'my-transaction-id'

paymend_address = receiver.get_payment_address(trans_id)
is_complete, amount = receiver.payment_completed(trans_id, 42)

The get_payment_address method adds (if not already existing) a receive address with the label my-transaction-id to the Core wallet. The payment_completed method checks if the payment has been completed (42 or more coins in the address).

from tinycoinlib.send import TinyCoinSend

sender = TinyCoinSend('dogecoin')

transaction_id = sender.send(1.38, 'DMrzmskQzXJ9pDHQBxBu5de36UaH5EYtDa')

TinyCoinSend has two more methods, get_balance and get_details for wallet balance and transaction details (confirmations, fee, ...) enquery, respectively.

For bugs and ideas, please see our Issues. Further details are in CONTRIBUTING.md.
