How the ETH Optimism → DOT exchange runs
- Work out the amount in the calculator — orders start at 0.0374734 ETH Optimism.
- Give a DOT address on Polkadot and a contact for the order.
- Send ETH Optimism on Optimism, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Polkadot to your address. The order page shows the status.
Check this before sending ETH Optimism
- The address network is Polkadot. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 0.0374734 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.

Why people take the ETH Optimism → DOT route
- Fuel for PolkadotWithout Polkadot you cannot pay for a transfer or a contract call in Polkadot — the coin is needed for anything that happens in that ecosystem.
- Different basketsDaily moves of ETH and DOT over 90 days link at 0.65 (they travel alike) — the weaker the link, the less a portfolio rests on one coin.
- It works both waysThe DOT → ETH Optimism direction is open as well — going back into ETH takes the same route and the same automation.
Common questions: ETH Optimism → DOT
What rate does ETH Optimism to DOT run at?
As of Sep 30, 2026 10:15 it is 1 ETH Optimism = 2,214.61 DOT. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,679.67.
What amounts does ETH Optimism → DOT accept?
From 0.0374734 to 3,750 ETH Optimism per order. The floor is roughly $100.03.
Why can I not swap less than 0.0374734 ETH Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 0.0374734 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 DOT 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 DOT arrive in?
Polkadot arrives in its own Polkadot network — a plain DOT address is all you need.
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 DOT rate do over the month?
Over the month, minus 22.84%: a low of 1,991.99, a high of 2,948.54, an average of 2,452.33 DOT per 1 ETH Optimism.
Can I swap back, DOT for ETH Optimism?
Yes, the reverse is open too: 1 DOT = 0.000451539 ETH Optimism. The link to switch sits under the calculator.
