The figure is indicative; the exact amount is locked in the order.
One STRK ERC20 buys 0.0000113007 ETH Optimism right now; the other way round, 1 ETH Optimism is 88,489.98 STRK ERC20. Market over 24 hours: STRK ERC20 against ETH Optimism minus 2.8%. The week added minus 16.84%.
The weekly corridor ran from 0.0000109939 to 0.0000132915 ETH Optimism, a spread of 20.9%. A single order takes 7,421.15 to 374,000,000 STRK ERC20. In dollars that is roughly $198.31.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Starknet sits 174th ($196.23 M) and Ethereum 2th ($293.66 B).
Who takes the STRK ERC20 → ETH Optimism route
- Fuel for OptimismWithout Ethereum nothing moves in Optimism — every transfer and every contract call is paid in it.
- Different basketsHolding part of the amount in Ethereum loosens a portfolio's dependence on a single coin.
- A road both waysThe ETH Optimism → STRK ERC20 direction is open too, so going back into STRK takes the same route.

Payout network for ETH
The same ETH goes out in several networks. Rates and lower limits differ, and the fee is charged by the network itself.

How the STRK ERC20 → ETH Optimism order runs
- Work out the amount in the calculator: orders start at 7,421.15 STRK ERC20.
- Enter a ETH address in Optimism and a way to reach you.
- Send STRK ERC20 in Ethereum (ERC20) for exactly the amount stated in the order.
- Once the network confirms your transfer, Ethereum leaves for your address. The order page tracks every step.
Check this before sending STRK ERC20
- The address network is Optimism. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 7,421.15 STRK ERC20.
- Copy the address whole, then compare the first and last characters after pasting.
- Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: STRK ERC20 → ETH Optimism
What rate does STRK ERC20 to ETH Optimism run at?
As of Sep 17, 2026 00:38 it is 1 STRK ERC20 = 0.0000113007 ETH Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.0271962.
What amounts does STRK ERC20 → ETH Optimism accept?
From 7,421.15 to 374,000,000 STRK ERC20 per order. The lower limit is roughly $198.31.
Where does the 7,421.15 STRK ERC20 floor come from?
Network fees and order handling eat a small transfer alive — below 7,421.15 STRK ERC20 the swap stops making sense for either side.
What else is taken on top of the rate?
The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending STRK ERC20, and that one goes to the blockchain, not to us.
How long does STRK ERC20 to ETH Optimism take?
The clock starts with confirmations: the order goes into work once Ethereum (ERC20) confirms your transfer. After that it comes down to how busy the network is.
Which network will ETH Optimism arrive in?
The payout leaves in Optimism. Make sure the receiving wallet works with that network.
Where is receiving ETH cheaper?
The cheapest is usually ETH BEP20, ETH Arbitrum, ETH Optimism. Still, the network is chosen by what the recipient supports, not by the fee.
What if the rate moves while I am paying?
The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
Can I go back, ETH Optimism to STRK ERC20?
Yes, the reverse direction is open: 1 ETH Optimism = 88,935.32 STRK ERC20. The link sits right under the calculator.
