Ensure You Have a USDC Address on Coinbase
To view/create wallet addresses in Coinbase you can navigate to your profile's crypto addresses section by clicking here. Please Note: You may be prompted to sign in if you haven't already.
If you do not have a USDC address listed, then follow these steps to create one:
1) Click on the dropdown (this defaults to "Tradable assets") and select USD Coin (USDC) from the list as shown below.
2) Once you click on Create new address, you would have successfully created a USDC wallet address to use for withdrawing your funds using Coinbase.
Retry Your Dapper Withdrawal
Go back to your Dapper account to retry your USDC withdrawal using Connect With Coinbase. After signing into Coinbase you should be prompted to Authorize Wallet Access. Ensure you have USDC Wallet selected and click Authorize.
Once your wallet is authorized, follow the remaining steps to enter your desired amount and confirm your wallet address. You can then click Continue and your withdrawal will be sent to your connected Coinbase wallet.
