Polkadot (DOT) → Ethereum (ETH Optimism)

Q: What rate does DOT to ETH Optimism run at?

As of Sep 30, 2026 10:15 it is 1 DOT = 0.000451539 ETH Optimism. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.21.

Q: What amounts does DOT → ETH Optimism accept?

From 84.2779 to 8,260,000 DOT per order. The floor is roughly $101.98.

Q: Why can I not swap less than 84.2779 DOT?

The network fee and the handling do not depend on the amount. On a transfer below 84.2779 DOT 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 DOT, and the blockchain takes that one.

Q: How long does swapping DOT for ETH Optimism take?

The clock starts with confirmations: as soon as Polkadot 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 Polkadot closes in about 6 sec.

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 DOT to ETH Optimism rate do over the month?

Over the month, plus 29.6%: a low of 0.000339151, a high of 0.00050201, an average of 0.000411992 ETH Optimism per 1 DOT.

Q: Can I swap back, ETH Optimism for DOT?

Yes, the reverse is open too: 1 ETH Optimism = 2,214.61 DOT. 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 DOT gets you 0.000451539 ETH Optimism; the other way round, 1 ETH Optimism is 2,214.65 DOT. Over 24 hours DOT/ETH Optimism came in at plus 4.27%. Over the week, plus 3.81%.

The weekly range ran from 0.000409073 to 0.000477123 ETH Optimism, a spread of 16.64%. One order takes from 84.2779 to 8,260,000 DOT. In dollars that is roughly $101.98.

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 Polkadot at No. 52 ($2.06 B) and Ethereum at No. 2 ($325.93 B). Over 90 days the daily moves of DOT and ETH correlate at 0.65 (they travel alike).

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 DOT → ETH Optimism exchange runs

Work out the amount in the calculator — orders start at 84.2779 DOT.
Give a ETH address on Optimism and a contact for the order.
Send DOT on Polkadot, 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 DOT for ETH Optimism

Check this before sending DOT

The address network is Optimism. Sending through another network almost always means losing the transfer.
The transfer must not be smaller than 84.2779 DOT.
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.

Different basketsDaily moves of DOT and ETH 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 ETH Optimism → DOT direction is open as well — going back into DOT takes the same route and the same automation.
