Paste a viewing key
A unified full viewing key can see, but it can never spend. Turnstile has no code path that accepts a seed phrase or a spending key.

The Orchard pool stops taking deposits
Nothing new enters Orchard after the activation height. Value already inside is not frozen and cannot be lost — it leaves only by being spent out, through the turnstile.

Reading the chain tip…
The block height is the truth; the clock is an estimate derived from the 75-second block target. Turnstile reads the tip from mainnet every minute — if it cannot, it says so rather than showing you a number it made up.
Live, or it says so — never a guess
Every number below is read from the chain or carries the source it was read from.

Turnstile is a read-only tool by construction, not by promise.

Turnstile scans mainnet
Your key is held in memory, used to read pool balances via zingolib, and discarded. Nothing is logged, stored, or persisted.

A pool-by-pool breakdown, a plain verdict, and the exact migration steps for the wallet you actually use.
What Turnstile can and cannot see
A viewing key is Zcash selective disclosure working exactly as designed. This is the whole product, so we state it plainly.
What it can see
- The pool balances your viewing key is entitled to decrypt
- Transparent, Sapling and Orchard amounts, separately
- Public chain data anyone can already read
Held in memory for the length of the scan, then discarded.
What it can never see
- Your seed phrase — there is no field for one
- Your spending keys — no code path accepts them
- Your identity, email, or IP-linked history
Not behind a flag. Not for testing. Not ever.
Every step, for your wallet
