Depends on how pedantic you want to be, and how you define
'transaction'.  Frankly, if I were to have proof of an eavesdropper, I
would consider the transaction to be compromised and I'd scrub it.
Hence, QM makes it possible to have a key transaction between Alice and
Bob guaranteed to be free of eavesdroppers.
