Common questions: DAI → USDT Arbitrum

What rate does DAI to USDT Arbitrum run at?

As of Sep 17, 2026 12:03 it is 1 DAI = 1.0056 USDT Arbitrum. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.00.

What amounts does DAI → USDT Arbitrum accept?

From 100 to 10,000,000 DAI per order. The lower limit is roughly $100.00.

Where does the 100 DAI floor come from?

Network fees and order handling eat a small transfer alive — below 100 DAI the swap stops making sense for either side.

What else is taken on top of the rate?

The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending DAI, and that one goes to the blockchain, not to us.

How long does DAI to USDT Arbitrum take?

The clock starts with confirmations: the order goes into work once Dai confirms your transfer. After that it comes down to how busy the network is. A block in Dai closes in about 12 sec.

Will native USDT arrive, or a wrapper?

USDT Arbitrum is the standard USDT token in Arbitrum One — exactly what exchanges send when they withdraw into this network.

Not to receive. ETH comes into play later, when you want to send USDT from your address.

What is wrong with the official Arbitrum One bridge?

An official deposit from Ethereum into Arbitrum One means connecting a wallet and signing a contract transaction. Here you simply send DAI to the address from the order.

Which network will USDT Arbitrum arrive in?

The payout leaves in Arbitrum One. Make sure the receiving wallet works with that network.

Where is receiving USDT cheaper?

The cheapest is usually USDT SOL, USDT Polygon, USDT Arbitrum, USDT TON, USDT BEP20, USDT AVAX C, USDT Optimism. Still, the network is chosen by what the recipient supports, not by the fee.

What if the rate moves while I am paying?

The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
