US Dollar (USD) and USD Coin (USDC) are unified on Coinbase Exchange. You can trade USD and USDC on Coinbase’s USD markets, deposit USD and USDC to your USD account on a one-to-one basis, and withdraw your USD and USDC balance as USD cash or USDC on any supported network.
You can view your deposit and withdrawal history under your USD balance in the Portfolio tab. USDC deposit and withdrawal history reflect both the transaction and the USDC to USD conversion. Your USDC balance may appear temporarily whenever a transfer is being processed.
All USDC to USD conversions occur automatically during any of the mentioned transactions. Note: Conversions of large USDC transfers may occur in multiple transactions and may have several conversion activity events.
You can view your conversion activity by clicking the USD line in the All Activity tab of your portfolio.
