Common questions: ORCA → ARB

What rate does ORCA to ARB run at?

As of Sep 30, 2026 19:30 it is 1 ORCA = 7.8507 ARB. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.60.

What amounts does ORCA → ARB accept?

From 62.4117 to 6,250,000 ORCA per order. The floor is roughly $99.86.

Why can I not swap less than 62.4117 ORCA?

The network fee and the handling do not depend on the amount. On a transfer below 62.4117 ORCA 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 ORCA, and the blockchain takes that one.

How long does swapping ORCA for ARB take?

The clock starts with confirmations: as soon as Orca 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 ORCA to ARB rate do over the month?

Over the month, minus 48.78%: a low of 6.5031, a high of 15.263, an average of 8.7317 ARB per 1 ORCA.

Can I swap back, ARB for ORCA?

Yes, the reverse is open too: 1 ARB = 0.127374 ORCA. The link to switch sits under the calculator.
