For most people, no. Tap where your ZEC is.
Not sure? Addresses starting t1 are public, zs or u1 are private, and zc is the old Sprout pool.
On an exchange or in an ETF
Nothing to do.
The exchange or fund handles the upgrade for you. Deposits and withdrawals may pause for a few hours around it; that is normal.

Update the app when its NU7 version is out.
None of the main wallets has released it yet (checked 20 Oct). Don't send ZEC in the hour around the upgrade: a payment still waiting then can be dropped and need sending again.

On Ledger's old app, act by 5 Nov.
Ledger removes the old “Zcash Shielded” app on 5 Nov, and its own Zcash app can't see that app's shielded ZEC. Ledger's fix: unshield it in Zkool first. Keystone and Trezor: update when they ship NU7 support.

From the chain's own record of each pool, since 2016
Sapling (2018) made private payments practical on phones · Orchard (2022) needs no trusted setup · Ironwood (2026) is the newest pool, live since July 2026
The dip: between Apr and Jul 2026, Orchard shrank by 0.9 million ZEC while transparent grew by 1.1 million, so the share fell from 31% to 25%. It has since recovered to 29%.
