How the ERA → ARB exchange runs
- Work out the amount in the calculator — orders start at 1,502.54 ERA.
- Give a ARB address on Arbitrum and a contact for the order.
- Send ERA on Caldera, exactly the amount the order shows.
- Nothing else is needed from you: as soon as the network confirms the transfer, the robot sends Arbitrum to your address. The order page shows the status.
Check this before sending ERA
- The address network is Arbitrum. Sending through another network almost always means losing the transfer.
- The transfer must not be smaller than 1,502.54 ERA.
- 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.

Common questions: ERA → ARB
What rate does ERA to ARB run at?
As of Sep 30, 2026 12:55 it is 1 ERA = 0.328575 ARB. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.066822.
What amounts does ERA → ARB accept?
From 1,502.54 to 150,000,000 ERA per order. The floor is roughly $100.26.
Why can I not swap less than 1,502.54 ERA?
The network fee and the handling do not depend on the amount. On a transfer below 1,502.54 ERA 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 ERA, and the blockchain takes that one.
How long does swapping ERA for ARB take?
The clock starts with confirmations: as soon as Caldera 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 ERA to ARB rate do over the month?
Over the month, minus 51.11%: a low of 0.277744, a high of 0.787948, an average of 0.391183 ARB per 1 ERA.
Can I swap back, ARB for ERA?
Yes, the reverse is open too: 1 ARB = 3.0434 ERA. The link to switch sits under the calculator.
