Bitcoin Signed Message Verifier

A simple Golang package with a single purpose, to verify messages signed via Bitcoin message signing (BMS).

Requirements

• Golang 1.18+

Installation

Your $PATH must contain the Go path and the Go bin path (see GoLang's getting started for more information).

Once done, you can install this package:

go get -u github.com/Fueav/verify-signed-message

Usage

For examples, checkout the example folder.

Support

This library tries to support as many signatures as possible.

Current support:

• Any wallet that does signing like Electrum, example:
  • Electrum: P2PKH, P2WPKH and P2WPKH-P2SH
  • Coinomi: P2PKH, P2WPKH and P2WPKH-P2SH
  • Samourai: P2PKH, P2WPKH and P2WPKH-P2SH
  • Mycelium: P2PKH, P2WPKH and P2WPKH-P2SH
• Any wallet that allows for legacy address signatures (P2PKH), example:
  • Bitcoin Core
• Any wallet that follows BIP 137, example:
  • Trezor: P2PKH, P2WPKH and P2WPKH-P2SH
• Taproot (P2TR)
  • The verification is using the internal key, so only addresses without a tapscript are allowed.

Currently not supported:

• Pay-to-Witness-Script-Hash (P2WSH)
• BIP-322

Development

This package is developed in-house and pushed from our internal repository to GitHub.
