To make clear, a transaction spends a number of inputs (that are outputs of earlier transactions) and creates a number of outputs (typically together with a “change output” sending extra worth again to the sender). The mining payment is just given implicitly by the distinction between the entire enter and output values.

If a transaction incorporates a number of inputs whose prevouts are encumbered with a multisignature script, we’d name it a multisig transaction, however the multisig solely actually occurs on the particular person enter stage. The signature accompanying this enter should be a results of an settlement between a number of events, however this does not place every other limitations on what the transaction can appear like, so long as the events agree on it. A multisig transaction can have 100 outputs to 100 completely different addresses, identical to a non-multisig transaction.

So sure, it’s undoubtedly potential for the escrow to have an output that pays them a payment within the transaction that additionally pays out the vendor.
