Starknet (STRK ERC20) → Ethereum (ETH Optimism)

Q: What rate does STRK ERC20 to ETH Optimism run at?

As of Sep 30, 2026 20:55 it is 1 STRK ERC20 = 0.000015597 ETH Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.0418724.

Q: What amounts does STRK ERC20 → ETH Optimism accept?

From 2,373.17 to 239,000,000 STRK ERC20 per order. The floor is roughly $99.22.

Q: Why can I not swap less than 2,373.17 STRK ERC20?

The network fee and the handling do not depend on the amount. On a transfer below 2,373.17 STRK ERC20 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 STRK ERC20, and the blockchain takes that one.

Q: How long does swapping STRK ERC20 for ETH Optimism take?

The clock starts with confirmations: as soon as Ethereum (ERC20) 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 STRK ERC20 to ETH Optimism rate do over the month?

Over the month, plus 52.59%: a low of 0.0000102206, a high of 0.0000183322, an average of 0.0000131612 ETH Optimism per 1 STRK ERC20.

Q: Can I swap back, ETH Optimism for STRK ERC20?

Yes, the reverse is open too: 1 ETH Optimism = 64,113.47 STRK ERC20. 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.

Right now 1 STRK ERC20 gets you 0.000015597 ETH Optimism; the other way round, 1 ETH Optimism is 64,114.75 STRK ERC20. Over 24 hours STRK ERC20/ETH Optimism came in at minus 2.85%. Over the week, plus 5.78%.

The weekly range ran from 0.0000142481 to 0.0000161148 ETH Optimism, a spread of 13.1%. One order takes from 2,373.17 to 239,000,000 STRK ERC20. In dollars that is roughly $99.22.

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 Starknet at No. 150 ($307.58 M) and Ethereum at No. 2 ($327.88 B). Over 90 days the daily moves of STRK and ETH correlate at 0.17 (they travel apart).

Which network ETH arrives in

The same ETH goes out in several networks. Each has its own rate and its own floor, and the fee is charged by the network itself.

How the STRK ERC20 → ETH Optimism exchange runs

Work out the amount in the calculator — orders start at 2,373.17 STRK ERC20.
Give a ETH address on Optimism and a contact for the order.
Send STRK ERC20 on Ethereum (ERC20), exactly the amount the order shows.
Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Ethereum to your address. The order page shows the status.

Swap STRK ERC20 for ETH Optimism

Check this before sending STRK ERC20

The address network is Optimism. Sending through another network almost always means losing the transfer.
The transfer must not be smaller than 2,373.17 STRK ERC20.
Copy the address in full, then check its first and last characters once it is pasted.
Send exactly the amount stated in the order: the automation matches your payment against it, and any difference sends the order back for recalculation.
