Common questions: STRK ERC20 → ARB

What rate does STRK ERC20 to ARB run at?

As of Sep 30, 2026 09:45 it is 1 STRK ERC20 = 0.21095 ARB. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.0425988.

What amounts does STRK ERC20 → ARB accept?

From 2,373.17 to 235,000,000 STRK ERC20 per order. The floor is roughly $100.84.

Why can I not swap less than 2,373.17 STRK ERC20?

The network fee and the handling do not depend on the amount. On a transfer below 2,373.17 STRK ERC20 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 STRK ERC20, and the blockchain takes that one.

How long does swapping STRK ERC20 for ARB take?

The clock starts with confirmations: as soon as Ethereum (ERC20) 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 ARB arrive in?

Arbitrum arrives in its own Arbitrum network — a plain ARB 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 STRK ERC20 to ARB rate do over the month?

Over the month, minus 29.81%: a low of 0.163461, a high of 0.293274, an average of 0.201808 ARB per 1 STRK ERC20.

Can I swap back, ARB for STRK ERC20?

Yes, the reverse is open too: 1 ARB = 4.7404 STRK ERC20. The link to switch sits under the calculator.
