Common questions: USDT Optimism → STRK ERC20

What rate does USDT Optimism to STRK ERC20 run at?
As of Oct 1, 2026 07:15 it is 1 USDT Optimism = 22.9408 STRK ERC20. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.986893.
What amounts does USDT Optimism → STRK ERC20 accept?
From 100.67 to 10,000,000 USDT Optimism per order. The floor is roughly $100.62.
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.

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.
