Bitcoin Signed Message Verifier

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

Requirements

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/bitonicnl/verify-signed-message

For examples, checkout the example folder.

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:

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