Register a wallet for USDC on Base

Payout network: Base. Confirm that your wallet can receive USDC on the Base network, then copy its address here. Use a wallet you control that can sign a message. Do not enter an exchange deposit address or select USDC on Ethereum, Polygon, Solana, or another network. Signing the one-time message does not send funds. Check the address carefully; transfers to a wrong address cannot be reversed.
