Tether (USDT Optimism) → Ethereum (ETH Optimism)

Q: What rate does USDT Optimism to ETH Optimism run at?

As of Sep 30, 2026 11:35 it is 1 USDT Optimism = 0.000375565 ETH Optimism. 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 USDT Optimism → ETH Optimism accept?

From 100.67 to 10,000,000 USDT Optimism per order. The floor is roughly $100.63.

Q: Why can I not swap less than 100.67 USDT Optimism?

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

Q: How long does swapping USDT Optimism for ETH Optimism take?

The clock starts with confirmations: as soon as Optimism 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 USDT Optimism to ETH Optimism rate do over the month?

Over the month, minus 8.29%: a low of 0.000360264, a high of 0.000418142, an average of 0.000394002 ETH Optimism per 1 USDT Optimism.

Q: Can I swap back, ETH Optimism for USDT Optimism?

Yes, the reverse is open too: 1 ETH Optimism = 2,662.6 USDT Optimism. 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.

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

Current maths: 0.000375565 ETH Optimism for every USDT Optimism, and 2,662.66 USDT Optimism per ETH Optimism in reverse. Over 24 hours USDT Optimism/ETH Optimism came in at plus 1.03%. Over the week, plus 3.26%.

The weekly range ran from 0.000362658 to 0.000378666 ETH Optimism, a spread of 4.41%. One order takes from 100.67 to 10,000,000 USDT Optimism. In dollars that is roughly $100.63.

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 Tether at No. 3 ($183.81 B) and Ethereum at No. 2 ($325.25 B). Over 90 days the daily moves of USDT and ETH correlate at 0.15 (they travel apart).
