What this pattern does

This page provides a lightweight, single-purpose regular expression for matching solana wallet address, 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

# Solana Wallet Address
# ReDoS-safe | RegexVault — Finance > Crypto

import re

solana_wallet_address_pattern = re.compile(r'^[1-9A-HJ-NP-Za-km-z]{32,44}$')

def validate_solana_wallet_address(value: str) -> bool:
    return bool(solana_wallet_address_pattern.fullmatch(value))

# Example
print(validate_solana_wallet_address("9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin"))  # 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

Solana uses Base58 (excludes 0, O, I, l). Valid addresses are 43-44 characters encoding a 32-byte Ed25519 public key. Program-derived addresses (PDAs) follow the same format but are not derived from private keys.
