Questions

Is this native USDC or a bridged wrapper?
Native USDC issued by Circle on Base. The transfer protocol burns on Arbitrum and mints on Base, so there is no third-party wrapper involved.
What does the bridge cost?
A small fee in USDC, made up of Circle's percentage fee plus the cost of delivering on Base. The exact figure is in the fee breakdown before you commit.
Do I need ETH on Base?
No. Circle delivers the USDC to your address, so an empty wallet is fine.
