Some slight corrections to how it should be documented:

address-balance [address] [crypto]

moneywagon address-balance doge --address=D8ZXs3JDdLuyRjG3wDtRQE2PMT4YQWELfZ

Also works with the crypto trailing:
moneywagon address-balance --address=D8ZXs3JDdLuyRjG3wDtRQE2PMT4YQWELfZ doge
moneywagon address-balance --address=D8ZXs3JDdLuyRjG3wDtRQE2PMT4YQWELfZ doge --verbose --paranoid=3

single-transaction [crypto] [txid]

moneywagon single-transaction ppc --txid=6dddc4deb0806d987844b429e73b20ce5f0355407cce220130b5eac8fa13970e | python -mjson.tool

--paranoid= can be added
--verbose only works if you do not feed it to the json interpreter.

historical-transactions [crypto] [address]

moneywagon historical-transactions doge --address=D8ZXs3JDdLuyRjG3wDtRQE2PMT4YQWELfZ | python -m json.tool

Multiexplorer Wallet is stuck generating QR codes, and never loads existing Wallet.

• Try get_single_transaction with 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b

These is due to the fact that both blockr and insight.bitpay somehow don't like this transaction. blockchain.info shows this, but doesn't seem to have implemented get_single_transaction

Hello,
First, let me say that I really appreciate your efforts in creating this code-- thank you. It looks nice but I haven't been able to put it to practice. I've installed it under python 3.7 but I get the following kind of error:

from moneywagon import get_block
Traceback (most recent call last):
File "", line 1, in
File "C:\Users\user\AppData\Local\Programs\Python\Python37-32\lib\site-packages\moneywagon__
init__.py", line 9, in
from .core import (
File "C:\Users\user\AppData\Local\Programs\Python\Python37-32\lib\site-packages\moneywagon\co
re.py", line 11, in
from bitcoin import serialize
ImportError: cannot import name 'serialize' from 'bitcoin' (C:\Users\user\AppData\Local\Program

I get this same kind of error on a linux machine as well under both python 2.7 and python 3 environment.
Secondly, cannot use $ moneywagon function at the command prompt to create keypairs.

Any suggestions?

Again, playing around with this tool around the genesis block.

$ moneywagon get-block --block_number 0 btc
Traceback (most recent call last):
  File "/usr/local/bin/moneywagon", line 199, in <module>

    raise ValueError("Only one of `block_hash`, `latest`, or `block_number` allowed.")
ValueError: Only one of `block_hash`, `latest`, or `block_number` allowed.

I would expect the genesis block to be printed out, just like:
moneywagon get-block --block_hash 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f btc
Other block values do work.

Seems like a tiny default value (to zero) problem ^^ Keep up with the amazing work!

Hi. I'm looking into implementing a light wallet where the client only handles addresses and keys, and there's a server that provides the information about the blockchain. This library would be great for that because it lets me start with multiple currencies without having to host all the blockchains, but I have a few questions:

• Is the full API documented in the README file? I'm missing a few things, like getting the balance of an address with a number of confirmations, or getting the unconfirmed balance, or getting specific information about transactions (like the scriptPubkey so I can sign it). Are those features available?
• Is there a way to access this remotely, like via a json/http interfase?

Thanks!

I can't find any public API available at the moment, but when they appear this would be a really nice to have for moneywagon.

• While the type of value field in inputs is float, in output it is a unicode string. The expected type should be same in both cases
• Also output of get_single_transaction in README doesn't match what we are getting actually

Something goes wrong when it is looking for README.md...

Hi, when I try to use the HistoricalTransactions() function to search 'doge' the result didn't show up, but I try 'btc' it works, wonder if there's any bug or something I miss?

from moneywagon import HistoricalTransactions
x = HistoricalTransactions().action('doge', 'myaddress')
print(x)

Is it possible to add support for Ether and BitShares such as Lick my Dick?

Hi @priestc, is it possible to deal with ERC20 tokens using this library? Would be really cool.

This explorer has a few currencies supported, but has no json API. Maybe someone could implement this using BeautifulSoup.

Hey guys,

Can this library be used for any altcoin? I have currently setup my own cryptocoin which is based on litecoin, but this is limited to my test environment with no intention to do anything public with it.

You have a long list of supported cryptocurrency, but I feel like the library isn't designed to support arbitrary custom coin implementations?

Thanks in advance

Here's the error message:

/moneywagon/__init__.py", line 333, in generate_keypair
    pub_byte, priv_byte = get_magic_bytes(crypto)
/moneywagon/core.py", line 823, in get_magic_bytes
    if priv_byte >= 128:
TypeError: '>=' not supported between instances of 'NoneType' and 'int'

This is happening because in core.py in get_magic_bytes function,

        pub_byte = crypto_data[crypto]['address_version_byte']
        priv_byte = crypto_data[crypto]['private_key_prefix']
        if priv_byte >= 128:
            priv_byte -= 128 #pybitcointools bug

Maybe we need to expand on currency support to accommodate this?

something like:

    support_categories = {
        'address': ['address_form', 'private_key_form'],
        'transaction': [ 'transaction_form', 'transaction_hash_algo', 'script_hash_algo'],
        'block': ['header_hash_algo'],
        'generate_keypair': ['address_version_byte', 'private_key_prefix'],
    }

The explorer at https://explorer.coinpayments.net supports mutltiple currencies, but does not have a json API. Someone should make a "screen scrape" using bs4 similar to he bcoin service. The html look clean enough to be feasible...

As per README.md
HistoricalTransactions().get('ltc', 'Lb78JDGxMcih1gs3AirMeRW6jaG5V9hwFZ')
AddressBalance().get('ppc', 'PVoei4A3TozCSK8W9VvS55fABdTZ1BCwfj')

don't work, instead Function().action() works.
Not sure if we want to fix doc or the function name.

Hi,
Logging this as a feature request. Feel free to ignore.

Today, I tried getting detail of all transactions in a block and it took half an hour. I feel it would be good moneywagon can natively support parallel operations

• get_single_transaction_multi should does parallel requests to get tx details
• can use a framework like tornado, eventlet
• can be applied to other functions also

When I tried to create a transaction, I got such an error:

In [1]: from moneywagon.tx import Transaction

In [2]: tx = Transaction('dash')
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

    366             )
    367

Looks like the process was broken by 3e1274a, when type of services current_price was transformed from list to dict.

I tried a bit of calls and while quering the genesis block and this related to it, I found out that its transaction fails. Yet most explorers display that transaction id for the genesis block (https://blockchain.info/fr/block-index/14849).
Anyway, I would expect that tool to return a valid output for that txid, even if genesis.

$ moneywagon single-transaction --txid=4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b btc

Would it be an option to include binance among the services supported? The docs for their public API can be found here.

While most services are returning value txout value in 'value' parameter

• blockr service is returning it in 'amount' , this is causing inconsistency in output parsing when blockr is selected.
• Have to cross check other services too
