Mark Karpelès(@MagicalTux):As part of the rebranding Yoroi→SecondFi, the app was fully revamped and version bumped from 7.x.x to 10.x.x. The code was moved from its old cryptoxide (no commits in 4 years) version to a pure-JS based on noble/curves. The signature code for ed25519 in there is fine, but the prefix which was supposed to be passed is lost in the adapter. It's being passed, but never assigned in the adapter, so an empty prefix is passed to hashDomainToScalar() resulting in the nonce being the transaction itself only.
