Oh yes, thank you for bringing this up to the community. This a great proposal this is exactly the kind of pragmatic improvement Zcash needs as adoption grows. Dynamic fees that preserve privacy while improving UX for time-sensitive transactions are very welcome. NozyWallet is eager to participate and help drive this forward.
About NozyWallet
NozyWallet is a privacy-first, Orchard-only wallet built in Rust on top of Zebrad. We enforce fully shielded transactions by default (no transparent addresses at all), making it one of the most privacy-maximalist wallets in the ecosystem.
How NozyWallet Can Contribute
Priority Delivery (4x fee) Clear toggle in send and swap flows: Standard vs Priority. We’ll show estimated confirmation benefit along with a clear privacy note (“Only reveals standard vs priority tier full Orchard shielding maintained”).
Speed Up semantics — We plan to add a prominent “Speed Up” button for expired or stuck transactions that automatically creates a new shielded tx at priority fee.
Smart defaults in the aggregator Nozy includes a BridgeKitty-style quote aggregator for shielded cross-chain swaps (NEAR Intents, etc.). We can intelligently recommend Priority only when it makes sense and combines it with privacy scoring.
Longer-term synergy — This pairs well with the work on Tachyon / Oblivious Sync readiness.
Regarding the valid point raised by @pitmutt about keeping Zcash usable for everyday users and avoiding fee spikes that hurt small transactions: we fully agree this is important. I understand this as well is not a block space auction like EIP-1559. Instead, it uses a rolling window to adjust the mean fee, allows a meaningfully lower minimum base fee, and lets users voluntarily pay more for faster inclusion. This should actually lower the bar for normal transaction inclusion compared to the current ZIP 317 system.
That’s a very important distinction. On affordability for everyday users (@pitmutt
’s concern):
This is a very valid worry. No one wants Zcash to become expensive or unusable for regular people because of whales. For NozyWallet’s approach we plan to:Keep Standard fee as the strict default for almost everything
Only suggest Priority for clearly time-sensitive cases (large swaps, urgent payments, etc.)
Always show the user a clear cost preview + estimated confirmation time before they confirm
Support keeping the marginal/base fee as low as possible.
The goal is to give users optional speed when they need it, while protecting the default experience for everyday shielded payments. If the rolling-window mechanism works as described, it should help prevent extreme fee spikes compared to a pure auction model.
