As of Oct 1, 2026 05:25 it is 1 USDT Optimism = 0.607897 ORCA. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.996951.
What amounts does USDT Optimism → ORCA accept?

Which network will ORCA arrive in?
Orca arrives in its own Orca network — a plain ORCA 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.

Over the month, minus 21.75%: a low of 0.551816, a high of 0.82214, an average of 0.701315 ORCA per 1 USDT Optimism.
