Simon's Cat (CAT) → Ethereum (ETH BASE)

Q: What rate does CAT to ETH BASE run at?

As of Sep 30, 2026 13:30 it is 1 CAT = 0.000000000852 ETH BASE. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.00000227277.

Q: What amounts does CAT → ETH BASE accept?

From 45,367,282.56 to 4,410,000,000,000 CAT per order. The floor is roughly $102.98.

Q: Why can I not swap less than 45,367,282.56 CAT?

The network fee and the handling do not depend on the amount. On a transfer below 45,367,282.56 CAT they eat a noticeable share of it, and the swap stops making sense for either side.

Q: 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 CAT, and the blockchain takes that one.

Q: How long does swapping CAT for ETH BASE take?

The clock starts with confirmations: as soon as Simon's Cat 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.

Q: Which network will ETH BASE arrive in?

The payout goes out on BASE. Check that the receiving wallet supports that network.

Q: Which network is cheaper for receiving ETH?

Usually ETH BEP20, ETH Arbitrum, ETH Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.

Q: 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.

Q: What did the CAT to ETH BASE rate do over the month?

Over the month, plus 5.06%: a low of 0.000000000734, a high of 0.000000001021, an average of 0.000000000819 ETH BASE per 1 CAT.

Q: Can I swap back, ETH BASE for CAT?

Yes, the reverse is open too: 1 ETH BASE = 1,173,814,119.26 CAT. The link to switch sits under the calculator.

The order runs on autopilot: the rate is locked when you create it, and the payout leaves as soon as the network confirms your transfer. No manual approval, no working hours.

Preliminary figure: the final amount is locked in the order.

The direction is holding at 0.000000000852 ETH BASE per 1 CAT (1,173,837,595.78 CAT per 1 ETH BASE). Over 24 hours CAT/ETH BASE came in at plus 1.37%. Over the week, plus 0.91%.

The weekly range ran from 0.000000000783 to 0.000000000904 ETH BASE, a spread of 15.43%. One order takes from 45,367,282.56 to 4,410,000,000,000 CAT. In dollars that is roughly $102.98.

The robot sends the payout in the BASE network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Simon's Cat at No. 969 ($16.99 M) and Ethereum at No. 2 ($325.67 B). Over 90 days the daily moves of CAT and ETH correlate at 0.41 (they travel alike).

Which network ETH arrives in

The same ETH goes out in several networks. Each has its own rate and its own floor, and the fee is charged by the network itself.

How the CAT → ETH BASE exchange runs

Work out the amount in the calculator — orders start at 45,367,282.56 CAT.
Give a ETH address on BASE and a contact for the order.
Send CAT on Simon's Cat, exactly the amount the order shows.
Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Ethereum to your address. The order page shows the status.

Swap CAT for ETH BASE

Check this before sending CAT

The address network is BASE. Sending through another network almost always means losing the transfer.
The transfer must not be smaller than 45,367,282.56 CAT.
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.
