trait Sign extends AnyRef

This is meant to be an abstraction for a org.bitcoins.core.crypto.ECPrivateKey, sometimes we will not have direct access to a private key in memory -- for instance if that key is on a hardware device -- so we need to create an abstraction of the signing process. Fundamentally a private key takes in a scodec.bits.ByteVector and returns a ECDigitalSignature That is what this abstraction is meant to represent. If you have a ECPrivateKey in your application, you can get it's Sign type by doing this:

val key = ECPrivateKey() val sign: scodec.bits.ByteVector => Future[ECDigitalSignature] = key.signFunction

If you have a hardware wallet, you will need to implement the protocol to send a message to the hardware device. The type signature of the function you implement must be scodec.bits.ByteVector => Future[ECDigitalSignature]
