As of Nov 1, 2026 09:59 it is 1 CAT = 0.000000001317 ZEC. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.00000164859.

What amounts does CAT → ZEC accept?

From 99,800,399.2 to 6,130,000,000,000 CAT per order. The lower limit is roughly $162.67.

Where does the 99,800,399.2 CAT floor come from?

Network fees and order handling eat a small transfer alive — below 99,800,399.2 CAT the swap stops making sense for either side.

What else is taken on top of the rate?

The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending CAT, and that one goes to the blockchain, not to us.

How long does CAT to ZEC take?

The clock starts with confirmations: the order goes into work once Simon's Cat confirms your transfer. After that it comes down to how busy the network is.

Which network will ZEC arrive in?

Zcash leaves in its own Zcash network — a plain ZEC address is all you need.

What if the rate moves while I am paying?

The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.

What did the CAT to ZEC rate do this month?

The month came in at minus 17.89%. Low 0.000000001303, high 0.000000001747, middle 0.000000001553 ZEC per CAT.

Can a CAT to ZEC swap be traced?

Transfers in public networks sit in the explorer for anyone to read. Privacy coins close that off: Monero always, Zcash and Dash when a shielded transfer is chosen.

Can I go back, ZEC to CAT?

Yes, the reverse direction is open: 1 ZEC = 765,282,081.85 CAT. The link sits right under the calculator.
