All current ActivityPub implementations are domain-bound. Outgoing requests use HTTP signatures that are verified by fetching the actor info which includes the public key used to verify that signature. Maybe with some code modification it should be possible for instances to send out full activity including the signature to relay, and for that relay to send out unmodified signed activity to receiving instance, but then again, you have to have direct access to sending instance to fetch the keys of newly federated accounts.
