Swap USDC Arbitrum for DAI

Check this before sending USDC Arbitrum

The address network is Dai. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 200 USDC Arbitrum.
Copy the address whole, then compare the first and last characters after pasting.
Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon all use the same address shape (0x…). Make sure the wallet is switched to Ethereum.
To move DAI on later, put a little ETH at the same address.
Coins go through an AML check: a flagged transfer can be held until the check is finished.

Common questions: USDC Arbitrum → DAI

What rate does USDC Arbitrum to DAI run at?

As of Sep 17, 2026 15:53 it is 1 USDC Arbitrum = 1.0028 DAI. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.00.

What amounts does USDC Arbitrum → DAI accept?

From 200 to 10,000,000 USDC Arbitrum per order. The lower limit is roughly $199.91.

Where does the 200 USDC Arbitrum floor come from?

Network fees and order handling eat a small transfer alive — below 200 USDC Arbitrum 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 USDC Arbitrum, and that one goes to the blockchain, not to us.

How long does USDC Arbitrum to DAI take?

The clock starts with confirmations: the order goes into work once Arbitrum One confirms your transfer. After that it comes down to how busy the network is. A block in Arbitrum One closes in about 0.25 sec.

Will native DAI arrive, or a wrapper?

DAI is the standard DAI token in Ethereum — exactly what exchanges send when they withdraw into this network.

Do I need ETH to receive DAI?

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

What is wrong with the official Arbitrum One bridge?

The official withdrawal from Arbitrum One to Ethereum waits around seven days — that is the challenge period of an optimistic rollup. Here DAI arrives as soon as the order is processed.

Which network will DAI arrive in?

Dai leaves in its own Dai network — a plain DAI address is all you need.

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.

Can I go back, DAI to USDC Arbitrum?

Yes, the reverse direction is open: 1 DAI = 1.0052 USDC Arbitrum. The link sits right under the calculator.
