Wallet and signatures	Not needed: the coins go to the address from the order	Needed: connect the wallet and sign contract transactions

Timing	After confirmations in Ethereum; the order page tracks it	Depends on the bridge and the load of both networks

What rate does DAI to USDC Arbitrum run at?

As of Nov 2, 2026 02:59 it is 1 DAI = 1.005 USDC Arbitrum. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.00.

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 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.

Which network will USDC Arbitrum arrive in?

Where is receiving USDC cheaper?

Will native USDC arrive, or a wrapper?

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.

What if the rate moves while I am paying?
