👾 Description of the issue

Problem

Currently there is no way to calculate recovery id (v) when we sign an Ethereum Transaction from the SDK.

Solution

The recovery ID is an index from 0 to 3, which indicates which of the 4 possible public keys is the correct one. Because the key recovery operation yields multiple potential public keys, the correct key must either be stored alongside the signature or you must be willing to try each recovery ID in turn until you find one that outputs the key you are expecting.

Recovery operation is described in SEC1v2, section 4.1.6.

OpenSSL is not currently supporting the RecID generation it has been added as an issue in OpenSSL repo. This is not worth the effort at this point as it would need lots of custom implementations that could be deprecated on a certain OpenSSL release.

Moving to backlog for now.
