Eh, you did see https://demo.taler.net/?

Well, for starters, we're not implementing OTX but the Taler protocol,
which respects consumer privacy.

You can spend smaller increments, or rather: spend a fraction and obtain
change for the remainder. For unlinkability, you do need talk to the
exchange to get unlinkable change.

We're implementing it right now. The design calls for the receiver to be
again identified like a merchant, but of course if that is not required
in the jurisdiction where the exchange operates, you could disable it.
