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

Current maths: 2,703.7 USDC BASE for every ETH Optimism, and 0.000369863 ETH Optimism per USDC BASE in reverse. Over 24 hours ETH Optimism/USDC BASE came in at minus 0.96%. Over the week, minus 0.94%.

The weekly range ran from 2,648.68 to 2,736.33 USDC BASE, a spread of 3.31%. One order takes from 0.037454 to 3,690 ETH Optimism. In dollars that is roughly $101.38.

The robot sends the payout in the BASE network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Ethereum at No. 2 ($330.5 B) and USD Coin at No. 6 ($74.32 B). Over 90 days the daily moves of ETH and USDC correlate at 0 (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.
