When you already hold USDC on another platform (e.g. exchange, non-connected wallet) and want to send USDC to Buzzing, crypto transaction is one of your choice.

User flow
- On Buzzing, click Deposit and select Crypto → Direct Deposit.
- You will see:
- The unique USDC deposit address on Base
- A QR code for the same address
- On the external platform (e.g. exchange / wallet app):
- Chooses USDC
- Selects Send / Transfer
- Pastes the Buzzing deposit address or scans the QR code
- Selects Base as the network
- Confirms the transaction
- Once the transaction is confirmed on-chain, Buzzing detects the deposit and updates the USDC balance.
