USD Coin (USDC AVAX C) → Ethereum (ETH Optimism)

Q: What rate does USDC AVAX C to ETH Optimism run at?

As of Sep 30, 2026 20:50 it is 1 USDC AVAX C = 0.000371975 ETH Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.994167.

Q: What amounts does USDC AVAX C → ETH Optimism accept?

From 100.67 to 10,000,000 USDC AVAX C per order. The floor is roughly $100.64.

Q: Why can I not swap less than 100.67 USDC AVAX C?

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

Q: 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 USDC AVAX C, and the blockchain takes that one.

Q: How long does swapping USDC AVAX C for ETH Optimism take?

The clock starts with confirmations: as soon as Avalanche C-Chain 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.

Q: Which network will ETH Optimism arrive in?

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

Q: Which network is cheaper for receiving ETH?

Usually ETH BEP20, ETH Arbitrum, ETH Optimism works out cheaper. Still, the network is picked by what the recipient accepts, not by the fee.

Q: 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.

Q: What did the USDC AVAX C to ETH Optimism rate do over the month?

Over the month, minus 10.19%: a low of 0.00036029, a high of 0.000418187, an average of 0.000392854 ETH Optimism per 1 USDC AVAX C.

Q: Can I swap back, ETH Optimism for USDC AVAX C?

Yes, the reverse is open too: 1 ETH Optimism = 2,688.3 USDC AVAX C. The link to switch sits under the calculator.

The order runs on autopilot: the rate is locked when you create it, and the payout leaves as soon as the network confirms your transfer. No manual approval, no working hours.

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 USD Coin at No. 6 ($74.25 B) and Ethereum at No. 2 ($326.45 B). Over 90 days the daily moves of USDC and ETH correlate at 0 (they travel apart).
