Easy Bitcoin RPC

Easy Bitcoin RPC is a simple and easy to use Python library for Bitcoin RPC

Installation

Use the package manager pip to install.

pip install easybitcoinrpc

Usage

Connecting

from easybitcoinrpc import RPC

# RPC() returns connection object

rpc = RPC() # defaults: ip=127.0.0.1, port="8332", user="user", password="password", wallet=None

rpc = RPC(user="rpcuser", password="rpcpassword")

rpc = RPC(ip="192.168.1.1", port=9999, user="rpcuser", password="rpcpassword")

rpc = RPC(wallet="Wallet")

Specifing wallet when connection is made is prefered method to get access to wallet, loading wallet after connecting sometimes dosn't work.

RPC methods

RPC object has methods for all Bitcoins RPC calls and those methods are seperated into sections as on Bitcoin RPC API Reference

from easybitcoinrpc import RPC
rpc = RPC()

rpc.blockchain # returns object which has all methods from blockchain category
rpc.wallet # returns object which has all methods from wallet category
rpc.util # returns object which has all methods from util category
rpc.mining # returns object which has all methods from mining category
rpc.network # returns object which has all methods from network category
rpc.generating # returns object which has all methods from generating category
rpc.control # returns object which has all methods from control category
rpc.transactions # returns object which has all methods from transactions category

rpc.batch(["getbestblockhash"]) # batch method also can be used to made requests
rpc.batch(["getblock", 1000]) # parameters are passed in list, where first parameter is RPC command

All methods have documentation copied from Bitcoin RPC API Reference, they also have parameters specified with their types and their default values.

Data

Methods which implements blocks and transactions related calls, returns custom data objects like Block, Transaction, Vin, ScriptSig and etc.

from easybitcoinrpc import RPC
rpc = RPC()

block = rpc.blockchain.get_best_block()
transactions = block.get_transactions()
vins = transactions[0].get_vins()
script_sig = vins[0].get_script_sig()
r = script_sig.get_r()

Those data objects have getters for all values.

from easybitcoinrpc import RPC
rpc = RPC()

block = rpc.blockchain.get_best_block()

block.get_time()
block.get_previous_block()
block.get_hash()

Objects have special methods, not provided by Bitcoin RPC, like for example checking if transaction is segwit or getting ECDSA values.

from easybitcoinrpc import RPC
rpc = RPC()

block = rpc.blockchain.get_best_block()

for t in block.get_transactions():
    if t.is_segwit():
        print(t.get_txid())
    else:
        for v in t.get_vins():
            print(t.get_txid(), v.get_sequence(), v.get_script_sig().get_r())

Objects have overridden str methods for better visualisation of data.

from easybitcoinrpc import RPC
rpc = RPC()

block = rpc.blockchain.get_best_block()
print(block)

Transaction object has TransactionSummary object for presenting transaction like on blockchain.com.

from easybitcoinrpc import RPC
rpc = RPC()

t = rpc.transactions.get_transaction('9c38bd04960abf7a77d1ce132f9ae62b37fd4509954f87b19b408141fc0cdcd6')
print(t.get_summary())
