USD Coin (USDC BASE) → Ethereum (ETH Arbitrum)

Q: What rate does USDC BASE to ETH Arbitrum run at?

As of Sep 30, 2026 12:25 it is 1 USDC BASE = 0.000374417 ETH Arbitrum. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.00.

Q: What amounts does USDC BASE → ETH Arbitrum accept?

From 100.67 to 10,000,000 USDC BASE per order. The floor is roughly $100.65.

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

The network fee and the handling do not depend on the amount. On a transfer below 100.67 USDC BASE 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 BASE, and the blockchain takes that one.

Q: How long does swapping USDC BASE for ETH Arbitrum take?

The clock starts with confirmations: as soon as BASE 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 Arbitrum arrive in?

The payout goes out on Arbitrum One. 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 BASE to ETH Arbitrum rate do over the month?

Over the month, minus 8.27%: a low of 0.00036029, a high of 0.000418187, an average of 0.000394036 ETH Arbitrum per 1 USDC BASE.

Q: Can I swap back, ETH Arbitrum for USDC BASE?

Yes, the reverse is open too: 1 ETH Arbitrum = 2,670.76 USDC BASE. 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.
