What rate does ETH Arbitrum to ERA run at?
As of Oct 1, 2026 00:55 it is 1 ETH Arbitrum = 40,187.4 ERA. The figure updates on its own, and the calculator always shows the current one. On the market that is around $2,679.37.
What amounts does ETH Arbitrum → ERA accept?

Why can I not swap less than 0.0374734 ETH Arbitrum?

Which network will ERA arrive in?
Caldera arrives in its own Caldera network — a plain ERA 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.
