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

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 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

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

package validation

import "regexp"

var hdWalletDerivationPathBip32Bip44Re = regexp.MustCompile(`^m(?:\/(?:[0-9]+\'?|[0-9]+h?))+$`)

func ValidateHdWalletDerivationPathBip32Bip44(s string) bool {
    return hdWalletDerivationPathBip32Bip44Re.MatchString(s)
}

// Example
// fmt.Println(ValidateHdWalletDerivationPathBip32Bip44("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 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

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'.
