Common questions: USDT Optimism → ZBT

What rate does USDT Optimism to ZBT run at?

As of Sep 30, 2026 16:35 it is 1 USDT Optimism = 11.5339 ZBT. 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 → ZBT 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.

How long does swapping USDT Optimism for ZBT take?

The clock starts with confirmations: as soon as Optimism 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 ZBT arrive in?

ZEROBASE arrives in its own ZEROBASE network — a plain ZBT 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 ZBT rate do over the month?

Over the month, minus 8.6%: a low of 10.8498, a high of 13.1561, an average of 12.0394 ZBT per 1 USDT Optimism.
