HD Wallet Derivation Path (BIP-32 / BIP-44) Regex for Python

What this pattern does

This page provides a well-structured, multi-part regular expression for matching hd wallet derivation path (bip-32 / bip-44), ported and verified for Python. Financial data validation has zero tolerance for false negatives — a missed invalid entry can corrupt downstream calculations. The snippet below is ready to drop into your Python project — whether you're validating in a Django view, a FastAPI endpoint, or a standalone data processing script.

Python Implementation

# HD Wallet Derivation Path (BIP-32 / BIP-44)
# ReDoS-safe | RegexVault — Finance > Crypto

import re

hd_wallet_derivation_path_bip32_bip44_pattern = re.compile(r'^m(?:\/(?:[0-9]+\'?|[0-9]+h?))+$')

def validate_hd_wallet_derivation_path_bip32_bip44(value: str) -> bool:
    return bool(hd_wallet_derivation_path_bip32_bip44_pattern.fullmatch(value))

# Example
print(validate_hd_wallet_derivation_path_bip32_bip44("m/44'/0'/0'/0/0"))  # True

Test Cases

When to use this pattern

This pattern is drawn from the Finance > Crypto category and carries a ReDoS-safe certification. That matters for Python developers because particularly important in Python web servers where CPU-bound regex operations can stall concurrent request handling. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.

Common Pitfalls

Technical Notes

BIP-44 path: m / purpose' / coin_type' / account' / change / address_index. Apostrophe (') or 'h' suffix denotes hardened derivation. Bitcoin: m/44'/0'/0'. Ethereum: m/44'/60'/0'. Solana: m/44'/501'/0'.
