Stablecoins from Ethereum to Arbitrum One: DAI → USDC Arbitrum

Q: What rate does DAI to USDC Arbitrum run at?

As of Sep 17, 2026 15:48 it is 1 DAI = 1.0051 USDC Arbitrum. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.00.

Q: 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.

Q: How long does DAI to USDC 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.

Q: Which network will USDC Arbitrum arrive in?

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

Q: Where is receiving USDC cheaper?

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

Q: Will native USDC arrive, or a wrapper?

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

Q: Do I need ETH to receive USDC Arbitrum?

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

Q: 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.

Q: 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.

Q: Can I go back, USDC Arbitrum to DAI?

Yes, the reverse direction is open: 1 USDC Arbitrum = 1.0029 DAI. The link sits right under the calculator.

The direction runs at 1.0051 USDC Arbitrum per DAI, or 0.994918 DAI per USDC Arbitrum. Market over 24 hours: DAI against USDC Arbitrum minus 0.01%. The week added a move of 0%.

Check this before sending DAI

The address network is Arbitrum One. Sending through another network usually means losing the transfer.
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 Arbitrum One.
To move USDC 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.

What lands at your address	USDC in Arbitrum One	The same stablecoin; turning USDT into USDC is a separate step
Wallet and signatures	Not needed: the coins go to the address from the order	Needed: connect the wallet and sign contract transactions
A coin for fees in Arbitrum One	Not needed to receive	Often needed, or the funds cannot be claimed or moved on
Timing	After confirmations in Ethereum; the order page tracks it	Depends on the bridge and the load of both networks
