How long does it take to exchange USDC (Optimism) to ARB (Arbitrum)?
The exchange runs automatically as soon as your USDC transaction receives the required number of confirmations on the Optimism (ERC20) network, and ARB is then sent to your address. The waiting time mainly depends on network load and the transaction fee you set.
Do I need to register to exchange USDC (Optimism) to ARB (Arbitrum)?
No. CCE Cash does not require an account or personal data. You only need a wallet address that supports ARB on the Arbitrum (ERC20) network.
Should I choose a fixed or floating rate?
With a fixed rate you receive exactly the amount shown when the order is created: the rate is frozen for 10 minutes, and your USDC must arrive within this time in the exact order amount. With a floating rate, the final amount is set when your transaction is confirmed and may go up or down with the market.
Which network should I use to send USDC?
Send USDC only via the Optimism (ERC20) network, and make sure your receiving address supports ARB on the Arbitrum (ERC20) network. Sending funds through a different network may result in their loss.
