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

Right now 1 ATOM gets you 1.722 USDC Optimism; the other way round, 1 USDC Optimism is 0.580726 ATOM. Over 24 hours ATOM/USDC Optimism came in at minus 2.45%. Over the week, minus 5.86%.

The weekly range ran from 1.6788 to 1.9065 USDC Optimism, a spread of 13.56%. One order takes from 58.2851 to 5,810,000 ATOM. In dollars that is roughly $100.25.

The robot sends the payout in the Optimism network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Cosmos at No. 83 ($915.49 M) and USD Coin at No. 6 ($74.36 B). Over 90 days the daily moves of ATOM and USDC correlate at 0.03 (they travel apart).

Which network USDC arrives in

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

Common questions: ATOM → USDC Optimism

What rate does ATOM to USDC Optimism run at?

As of Sep 30, 2026 14:15 it is 1 ATOM = 1.722 USDC Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.72.

What amounts does ATOM → USDC Optimism accept?

From 58.2851 to 5,810,000 ATOM per order. The floor is roughly $100.25.

Why can I not swap less than 58.2851 ATOM?

The network fee and the handling do not depend on the amount. On a transfer below 58.2851 ATOM 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 ATOM, and the blockchain takes that one.

How long does swapping ATOM for USDC Optimism take?

The clock starts with confirmations: as soon as Cosmos Hub 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 Cosmos Hub closes in about 6 sec.

Which network will USDC Optimism arrive in?

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

Which network is cheaper for receiving USDC?

Usually USDC SOL, USDC Arbitrum, USDC BEP20, USDC AVAX C, USDC Optimism, USDC Polygon works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.

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 ATOM to USDC Optimism rate do over the month?

Over the month, plus 15.23%: a low of 1.4546, a high of 1.8837, an average of 1.6544 USDC Optimism per 1 ATOM.

Can I swap back, USDC Optimism for ATOM?
