- Enter a ATOM address in Cosmos Hub and a way to reach you. Receiving to an exchange? Add the Memo, or the payment will hang.
- Send USDC Optimism in Optimism for exactly the amount stated in the order.
- Once the network confirms your transfer, Cosmos leaves for your address. The order page tracks every step.
Check this before sending USDC Optimism
- The address network is Cosmos Hub. Sending through another network usually means losing the transfer.
- If the receiving wallet asks for a Memo, put it in the order.
- The transfer must not be smaller than 200 USDC Optimism.
- 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: USDC Optimism → ATOM
What rate does USDC Optimism to ATOM run at?
As of Nov 1, 2026 19:49 it is 1 USDC Optimism = 0.681235 ATOM. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.01.
What amounts does USDC Optimism → ATOM accept?
From 200 to 10,000,000 USDC Optimism per order. The lower limit is roughly $199.99.
Where does the 200 USDC Optimism floor come from?
Network fees and order handling eat a small transfer alive — below 200 USDC Optimism the swap stops making sense for either side.
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 USDC Optimism, and that one goes to the blockchain, not to us.
How long does USDC Optimism to ATOM take?

Which network will ATOM arrive in?
Cosmos leaves in its own Cosmos Hub network — a plain ATOM address is all you need. Some exchanges and wallets also need a Memo.
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.

The month came in at plus 16.24%. Low 0.484159, high 0.680542, middle 0.581541 ATOM per USDC Optimism.
