Lots of people missed this, I think. Soon, @vizorwallet will have quantum-unlinkable swaps, and it doesn't need to wait for a network upgrade. Yet another way it leads the privacy frontier of Zcash right now.
If your Zcash wallet uses NEAR Intents, each swap you make adds your shielded address to a public ledger. A quantum computer could use this to link all your payments that share the same key.
In Vizor, each swap will get its own key to prevent this.
