Javascript Implementation

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

const solanaWalletAddressRegex = /^[1-9A-HJ-NP-Za-km-z]{32,44}$/;

function validateSolanaWalletAddress(input: string): boolean {
  return solanaWalletAddressRegex.test(input);

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 JavaScript developers because especially critical in long-running Node.js event loops where a ReDoS vulnerability can block the entire process. 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.
