Bind your wallet (required)

Bind an address from your own wallet first. Once bound, transferring USDC from that address auto-credits (no fee). Without binding you can't top up — manual submission also verifies the transfer source.

Transaction hash (txHash) · fallback if not auto-credited

Transfers usually auto-credit after binding; if not credited after a few minutes, paste the tx hash to verify manually (no fee — the source must still be your bound address).

1. Bind your Base wallet, then USDC transfers auto-credit (no manual submission needed)

2. Fund from your own wallet; Base needs a little ETH for gas (~$0.01–0.1 — withdraw a small amount of ETH from an exchange to your wallet)
