How the ETH Optimism → STRK ERC20 exchange runs

  1. Work out the amount in the calculator — orders start at 0.037454 ETH Optimism.
  2. Give a STRK address on Ethereum (ERC20) and a contact for the order.
  3. Send ETH Optimism on Optimism, exactly the amount the order shows.
  4. Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Starknet to your address. The order page shows the status.

Swap ETH Optimism for STRK ERC20

Check this before sending ETH Optimism

  • The address network is Ethereum (ERC20). Sending through another network almost always means losing the transfer.
  • The transfer must not be smaller than 0.037454 ETH Optimism.
  • 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.

Common questions: ETH Optimism → STRK ERC20

What rate does ETH Optimism to STRK ERC20 run at?
As of Sep 30, 2026 20:55 it is 1 ETH Optimism = 64,113.47 STRK ERC20. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,680.51.
What amounts does ETH Optimism → STRK ERC20 accept?
From 0.037454 to 3,720 ETH Optimism per order. The floor is roughly $100.55.
Why can I not swap less than 0.037454 ETH Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 0.037454 ETH Optimism they eat a noticeable share of it, and the swap stops making sense for either side.
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 ETH Optimism, and the blockchain takes that one.
How long does swapping ETH Optimism for STRK ERC20 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. A block in Optimism closes in about 12 sec.
Which network will STRK ERC20 arrive in?
The payout goes out on Ethereum (ERC20). Check that the receiving wallet supports that network.
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.
What did the ETH Optimism to STRK ERC20 rate do over the month?
Over the month, minus 34.47%: a low of 54,548.82, a high of 97,841.26, an average of 78,102.65 STRK ERC20 per 1 ETH Optimism.
Can I swap back, STRK ERC20 for ETH Optimism?
Yes, the reverse is open too: 1 STRK ERC20 = 0.000015597 ETH Optimism. The link to switch sits under the calculator.
