A message signed in a Concordium wallet is prepended with the account address and 8 zero bytes. A verify_concordium_wallet_message_signature/verify_account_message_signature function should be available in the SDK that adds these prepends and verifies all signatures in the signature map (aka 2-level multi-sig accounts).
