Common questions: USDT Optimism → ERA

What rate does USDT Optimism to ERA run at?

As of Sep 30, 2026 23:10 it is 1 USDT Optimism = 14.8366 ERA. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.00.

What amounts does USDT Optimism → ERA accept?

From 100.67 to 10,000,000 USDT Optimism per order. The floor is roughly $100.63.

Why can I not swap less than 100.67 USDT Optimism?

The network fee and the handling do not depend on the amount. On a transfer below 100.67 USDT Optimism 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 USDT Optimism, and the blockchain takes that one.

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.

What did the USDT Optimism to ERA rate do over the month?

Over the month, minus 2.32%: a low of 14.0276, a high of 17.9692, an average of 16.1631 ERA per 1 USDT Optimism.
