BIP Utility Library

Introduction

This package allows generating mnemonics, seeds, private/public keys and addresses for different types of cryptocurrencies. In particular:

  • Mnemonic and seed generation as defined by BIP-0039

  • Private key encryption/decryption as defined by BIP-0038

  • Keys derivation as defined by:

  • Derivation of a hierarchy of keys as defined by:

  • Mnemonic and seed generation for Substrate (Polkadot/Kusama ecosystem)

  • Keys derivation for Substrate (Polkadot/Kusama ecosystem, same of Polkadot-JS)

  • Keys and addresses generation for Cardano (Byron-Legacy, Byron-Icarus and Shelley, same of Ledger and AdaLite/Yoroi wallets)

  • Mnemonic and seed generation for Monero

  • Keys and addresses/subaddresses generation for Monero (same of official Monero wallet)

  • Mnemonic and seed generation for Algorand (Algorand 25-word mnemonic)

  • Mnemonic and seed generation like Electrum wallet (v1 and v2)

  • Keys derivation like Electrum wallet (v1 and v2)

  • Generation of keys from a passphrase chosen by the user (“brainwallet”)

Other implemented functionalities:

  • Parse BIP-0032 derivation paths

  • Parse Substrate derivation paths

  • Extended key serialization as defined by SLIP-0032

  • Encode/Decode addresses for all the supported coins

  • Encode/Decode WIF

  • Encode/Decode base58 and base58 monero

  • Encode/Decode ss58)

  • Encode/Decode bech32 and bech32m

  • Encode/Decode Bitcoin Cash bech32

  • Get token account addresses for SPL tokens (i.e. Solana tokens)

Package dependencies:

Please note that, for the py-sr25519-bindings library, Rust is required to be installed.

  • Binance Chain

  • Binance Smart Chain

  • Bitcoin (and related test net)

  • Bitcoin Cash (and related test net)

  • Bitcoin Cash Simple Ledger Protocol (and related test net)

  • Elrond (MultiversX)

  • EOS

  • Ergo (and related test net)

  • Ethereum

  • Ethereum Classic

  • Fantom Opera

  • Filecoin

  • Fetch.ai

  • Harmony One (Ethereum and Cosmos addresses)

  • Huobi Heco Chain

  • IRIS Network

  • Kava

  • Kusama (based on BIP44 and ed25519 SLIP-0010, like TrustWallet, it won’t generate the same addresses of Polkadot-JS)

  • Litecoin (and related test net)

  • Mavryk

  • Metis

  • Monero (based on BIP44 and secp256k1 or ed25519 SLIP-0010, it won’t generate the same addresses of the official wallets, but it supports subaddresses generation)

  • Nano

  • Near Protocol

  • NEO (legacy and N3)

  • Neutron

  • Nimiq

  • OKEx Chain (Ethereum and Cosmos addresses)

  • Ontology

  • Optimism

  • Osmosis

  • Pi Network

  • Polkadot (based on BIP44 and ed25519 SLIP-0010, like TrustWallet, it won’t generate the same addresses of Polkadot-JS)

  • Polygon

  • Ripple

  • Secret Network

  • Solana

  • Stafi (Cosmos)

  • Stellar

  • Sui (only ed25519)

  • Terra

  • Tezos

  • Theta Network

  • Tron

  • VeChain

  • Verge

  • Zcash (and related test net)

  • Zilliqa

Supported Substrate coins:

  • Acala

  • Bifrost

  • Chainx

  • Edgeware

  • Karura

  • Kusama

  • Moonbeam

  • Moonriver

  • Phala Network

  • Plasm Network

  • Sora

  • Stafi

  • Polkadot

  • Generic Substrate coin

For what regards Monero, it’s also possible to generate the same addresses of the official wallets without using BIP44 derivation.

Clearly, for those coins that support Smart Contracts (e.g. Ethereum, Tron, …), the generated keys and addresses are valid for all the related tokens.

Install the package

The package can be simply installed via pip:

pip install bip_utils

NOTE: if you have problems building the ed25519_blake2b library (it usually happens on Windows), you can try one of the prebuilt wheels here.

Alternative secp256k1 library

For secp256k1 curve, the package uses coincurve by default (much faster). However, it also supports ecdsa, which is a pure Python implementation (i.e. slower).

To use ecdsa for secp256k1, edit the file bip_utils/ecc/conf.py and set USE_COINCURVE to False. Then install with pip:

pip install .

Test and Coverage

Install develop dependencies:

pip install -r requirements-dev.txt

To run tests:

python -m unittest discover

To run tests with coverage:

coverage run -m unittest discover
coverage report -m

To run code analysis:

mypy .
ruff check .

tox can also be used for testing and code analysis (check tox.ini for the environments).
