Common questions: USDT Arbitrum → DOT

What rate does USDT Arbitrum to DOT run at?

As of Sep 30, 2026 19:20 it is 1 USDT Arbitrum = 0.811483 DOT. The figure updates on its own, and the calculator always shows the current one. On the market that is around $1.01.

What amounts does USDT Arbitrum → DOT accept?

From 100.67 to 10,000,000 USDT Arbitrum per order. The floor is roughly $100.64.

Why can I not swap less than 100.67 USDT Arbitrum?

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

How long does swapping USDT Arbitrum for DOT take?

The clock starts with confirmations: as soon as Arbitrum One 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 DOT arrive in?

Polkadot arrives in its own Polkadot network — a plain DOT 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 Arbitrum to DOT rate do over the month?

Over the month, minus 34.13%: a low of 0.788634, a high of 1.2202, an average of 0.956639 DOT per 1 USDT Arbitrum.
