Common questions: USDC Optimism → CAT

What rate does USDC Optimism to CAT run at?

As of Oct 1, 2026 05:25 it is 1 USDC Optimism = 437,938.73 CAT. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.9985.

What amounts does USDC Optimism → CAT accept?

From 100.67 to 10,000,000 USDC Optimism per order. The floor is roughly $100.65.

Why can I not swap less than 100.67 USDC Optimism?

The network fee and the handling do not depend on the amount. On a transfer below 100.67 USDC Optimism they eat a noticeable share of it, and the swap stops making sense for either side.

Is anything charged on top of the rate?

The clock starts with confirmations: as soon as Optimism 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.

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 USDC Optimism to CAT rate do over the month?

Over the month, minus 19.39%: a low of 394,768.48, a high of 563,440.83, an average of 480,678.17 CAT per 1 USDC Optimism.
