How the ETH BASE → CAT exchange runs
- Work out the amount in the calculator — orders start at 0.0374734 ETH BASE.
- Give a CAT address on Simon's Cat and a contact for the order.
- Send ETH BASE on BASE, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Simon's Cat to your address. The order page shows the status.
Check this before sending ETH BASE
- The address network is Simon's Cat. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 0.0374734 ETH BASE.
- Copy the address in full, then check its first and last characters once it is pasted.
- Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.

Common questions: ETH BASE → CAT
What rate does ETH BASE to CAT run at?
As of Sep 30, 2026 13:30 it is 1 ETH BASE = 1,173,814,119.26 CAT. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,664.56.
What amounts does ETH BASE → CAT accept?
From 0.0374734 to 3,750 ETH BASE per order. The floor is roughly $99.97.
Why can I not swap less than 0.0374734 ETH BASE?
The network fee and the handling do not depend on the amount. On a transfer below 0.0374734 ETH BASE they eat a noticeable share of it, and the swap stops making sense for either side.
Is anything charged on top of the rate?
No. The payout is already worked out at the rate in the calculator. Separately you pay only the network fee for sending ETH BASE, and the blockchain takes that one.
How long does swapping ETH BASE for CAT take?
The clock starts with confirmations: as soon as BASE confirms your transfer, the order goes out for payout with no operator involved. After that the timing is set by how busy the network is — which is the difference between quick and instant. A block in BASE closes in about 12 sec.
Which network will CAT arrive in?
Simon's Cat arrives in its own Simon's Cat network — a plain CAT address is all you need.
What happens if the rate moves while I am paying?
Nothing: the rate is locked in the order and holds for as long as the order is alive. It is recalculated only if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the ETH BASE to CAT rate do over the month?
Over the month, minus 4.81%: a low of 979,020,728.1, a high of 1,362,505,402.52, an average of 1,225,516,709.86 CAT per 1 ETH BASE.
Can I swap back, CAT for ETH BASE?
Yes, the reverse is open too: 1 CAT = 0.000000000852 ETH BASE. The link to switch sits under the calculator.
