Today CAT goes for 0.000000000703 ETH BASE, and ETH BASE goes for 1,423,050,205.72 CAT. Market over 24 hours: CAT against ETH BASE minus 1.24%. The week added minus 2.67%.
The weekly corridor ran from 0.000000000711 to 0.000000000751 ETH BASE, a spread of 5.52%.
The payout leaves in the BASE network, so the receiving address has to belong to that network. By market cap Simon's Cat sits 1139th ($12.07 M) and Ethereum 2th ($276.28 B). Daily moves of CAT and ETH over 90 days line up at 0.37 (they travel apart).
Who takes the CAT → ETH BASE route
- Fuel for BASEWithout Ethereum nothing moves in BASE — every transfer and every contract call is paid in it.
- Different basketsDaily moves of CAT and ETH over 90 days line up at 0.37 (they travel apart) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH BASE → CAT direction is open too, so going back into CAT takes the same route.

How the CAT → ETH BASE order runs
- Work out the amount in the calculator and press the exchange button.
- Enter a ETH address in BASE and a way to reach you.
- Send CAT in Simon's Cat for exactly the amount stated in the order.
- Once the network confirms your transfer, Ethereum leaves for your address. The order page tracks every step.
Check this before sending CAT
- The address network is BASE. Sending through another network usually means losing the transfer.
- Copy the address whole, then compare the first and last characters after pasting.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: CAT → ETH BASE
What rate does CAT to ETH BASE run at?

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 ETH BASE 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 ETH BASE arrive in?
The payout leaves in BASE. Make sure the receiving wallet works with that network.
Where is receiving ETH cheaper?
The cheapest is usually ETH BEP20, ETH Arbitrum, ETH Optimism. Still, the network is chosen by what the recipient supports, not by the fee.
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.
