Signing a message with Bitcoin address? #35

Closed lf94 closed 3 years ago

Bity SA would love to support BitBox02, but it appears only message signing is possible with Ethereum. Does BitBox02 have the ability to do message signing for Bitcoin addresses? Really this is a huge blocker for us. We use it as a way to verify users own the wallet address.

The API does provide BTC message signing using btcSignMessage in https://github.com/digitalbitbox/bitbox02-api-js/blob/a58014f/src/bitbox02.js#L272-L296.

Or did you mean something else?

Ah, nope. I must've looked right over it then - thank you for pointing it out!

For what it's worth, the documentation fails to mention this method: https://github.com/digitalbitbox/bitbox02-api-js/blob/master/docs/methods.md
