Do transfers still expire automatically?

A side effect of accelerating the Splitchain network is that transfers no longer expire automatically.

This is because the prior 90-second time block also served as a natural expiry mechanism.

This change occurred during the Zucoin wallet app v197 update.

Now with transfers settling in potentially under 1 second, keeping the prior approach to expiring transfers just wouldn't work.

What's being done about it?

The team is evaluating ways to reintroduce expiration as an optional behavior, potentially through "metadata rules"—where a transaction can include instructions about how long it should remain valid.

How to retract a transfer now:

Currently, if a transfer needs to be "retracted" and hasn't settled yet, the simplest approach is to do a new transfer, superseding the previous one.
