Description

Currently, we're passing the relayer's private key to the RPC service to build transactions, which is not ideal unless we enforce each relayer to run its own RPC, which is fine at least during this MVP phase.

A better scoped flow would be for the RPC to return the unsigned tx for the relayer to sign locally, then broadcast directly or via the RPC.

What signature scheme is used to sign Cardano transactions?

What remote signers (AWS KMS) can be used? KMS does not support Ed25519 :(
