Wallet USDC on Base
—
1. Buy USDC with a card
USDC goes straight to your own wallet on Base. "Pay by card" picks the cheapest provider for you: Coinbase, Stripe, Rampnow or Transak.
Or send USDC from an exchange
Buy USDC on any exchange you already use and withdraw it to your own wallet. Network must be Base (not Ethereum, not Arbitrum).
- Exchange → Withdraw → USDC
- Network: Base, address: the one above
- When it arrives, press Refresh and add it to your balance
2. Move USDC to service balance
You sign a USDC transfer in your wallet. No gas: Coinbase's facilitator submits it.
