Preliminary figure: the final amount is locked in the order.

Current maths: 4.7404 STRK ERC20 for every ARB, and 0.210954 ARB per STRK ERC20 in reverse. Over 24 hours ARB/STRK ERC20 came in at minus 0.35%. Over the week, minus 17.75%.

The weekly range ran from 4.6945 to 5.9212 STRK ERC20, a spread of 26.13%. One order takes from 489.402 to 49,500,000 ARB. In dollars that is roughly $98.83.

The robot sends the payout in the Ethereum (ERC20) network, so the address has to belong to that network — a transfer to another one will not arrive. Market capitalisation puts Arbitrum at No. 68 ($1.37 B) and Starknet at No. 151 ($312.49 M). Over 90 days the daily moves of ARB and STRK correlate at 0.2 (they travel apart).

How the ARB → STRK ERC20 exchange runs

Work out the amount in the calculator — orders start at 489.402 ARB.
Give a STRK address on Ethereum (ERC20) and a contact for the order.
Send ARB on Arbitrum, exactly the amount the order shows.
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 ARB for STRK ERC20

Check this before sending ARB

The address network is Ethereum (ERC20). Sending through another network almost always means losing the transfer.
The transfer must not be smaller than 489.402 ARB.
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 ARB → STRK ERC20 route

Fuel for Ethereum (ERC20)Without Starknet you cannot pay for a transfer or a contract call in Ethereum (ERC20) — the coin is needed for anything that happens in that ecosystem.
Different basketsDaily moves of ARB and STRK over 90 days link at 0.2 (they travel apart) — the weaker the link, the less a portfolio rests on one coin.
It works both waysThe STRK ERC20 → ARB direction is open as well — going back into ARB takes the same route and the same automation.

Common questions: ARB → STRK ERC20

What rate does ARB to STRK ERC20 run at?

As of Sep 30, 2026 09:45 it is 1 ARB = 4.7404 STRK ERC20. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.201431.

What amounts does ARB → STRK ERC20 accept?

From 489.402 to 49,500,000 ARB per order. The floor is roughly $98.83.

Why can I not swap less than 489.402 ARB?

The network fee and the handling do not depend on the amount. On a transfer below 489.402 ARB 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 ARB, and the blockchain takes that one.

How long does swapping ARB for STRK ERC20 take?

The clock starts with confirmations: as soon as Arbitrum 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.

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 ARB to STRK ERC20 rate do over the month?

Over the month, plus 42.48%: a low of 3.4098, a high of 6.1177, an average of 5.0535 STRK ERC20 per 1 ARB.

Can I swap back, STRK ERC20 for ARB?

Yes, the reverse is open too: 1 STRK ERC20 = 0.21095 ARB. The link to switch sits under the calculator.
