The figure is indicative; the exact amount is locked in the order.
One STRK ERC20 buys 0.0000193001 ETH Optimism right now; the other way round, 1 ETH Optimism is 51,813.33 STRK ERC20. Market over 24 hours: STRK ERC20 against ETH Optimism minus 0.99%. The week added minus 0.98%.
The weekly corridor ran from 0.0000185471 to 0.0000203312 ETH Optimism, a spread of 9.62%. A single order takes 7,421.15 to 226,000,000 STRK ERC20. In dollars that is roughly $328.37.
The payout leaves in the Optimism network, so the receiving address has to belong to that network. By market cap Starknet sits 127th ($335.9 M) and Ethereum 2th ($275.41 B). Daily moves of STRK and ETH over 90 days line up at 0.43 (they travel alike).
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 basketsDaily moves of STRK and ETH over 90 days line up at 0.43 (they travel alike) — the looser the link, the less a portfolio depends on one coin.
- A road both waysThe ETH Optimism → STRK ERC20 direction is open too, so going back into STRK takes the same route.

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.
