What rate does USDC Optimism to ATOM run at?

Where does the 200 USDC Optimism floor come from?

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.
