Solana Wallet Address Regex for Go

What this pattern does

This page provides a lightweight, single-purpose regular expression for matching solana wallet address, ported and verified for Go. 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 Go project — whether you're validating in a Gin handler, a gRPC service, or a command-line tool.

Go Implementation

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

package validation

import "regexp"

var solanaWalletAddressRe = regexp.MustCompile(`^[1-9A-HJ-NP-Za-km-z]{32,44}$`)

func ValidateSolanaWalletAddress(s string) bool {
    return solanaWalletAddressRe.MatchString(s)
}

// Example
// fmt.Println(ValidateSolanaWalletAddress("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 Go developers because Go's RE2 engine is inherently safe from catastrophic backtracking, but this pattern has been additionally verified for correctness. 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.
