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

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 XMR 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 XMR arrive in?

Monero leaves in its own Monero network — a plain XMR 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.

Can a CAT to XMR 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, XMR to CAT?

Yes, the reverse direction is open: 1 XMR = 253,476,359.35 CAT. The link sits right under the calculator.
