Pycryptotools, Python library for crypto coin addresses and block explorers

This is a fork of Vitalik Buterin's original pybitcointools library.

It has been heavily modified and simplified to provide basic service such as:

• recovering address from a public key for various blockchain
• recovering wif from private key
• get the balance for a given address on a blockchain, using block explorer web services API
• get assets (token & NFT) linked to a given address on a blockchain

Since v0.4.0, the library focuses on these coin and explorer features: the transaction, wallet, BIP32 and mnemonic code inherited from pybitcointools has been removed. Use pycryptotools<0.4 if you need it.

Installation:

pip install pycryptotools

Library supports the following blockchains:

• Bitcoin mainnet & testnet
• Bitcoin Cash mainnet & testnet
• Litecoin mainnet & testnet
• Dogecoin mainnet & testnet
• Counterparty mainnet & testnet
• Ethereum mainnet & testnet
• Ethereum Classic mainnet & testnet
• Polygon mainnet & testnet

Requires Python 3.8 or later.

API keys

Coins take an optional apikeys dict, passed to their block explorers. Litecoin and Dogecoin balances come from SoChain, whose API expects a key:

from pycryptotools.coins import Litecoin

coin = Litecoin(apikeys={'API_KEY_SOCHAIN': '...'})
coin.get_coin_info(address)

SoChain may reject or rate-limit requests sent without a key; get_coin_info() then raises ValueError. The other supported coins need no API key.

Logging

The library logs through the standard logging module, under the pycryptotools logger, and is silent by default. To see its output, configure logging in your application, or set the level of all pycryptotools loggers at once:

import logging
import pycryptotools

logging.basicConfig()
pycryptotools.set_log_level(logging.DEBUG)
