This bridge runs on Circle's CCTP V2: your USDC is natively burned on the source chain and minted on Arc — no wrapped tokens. BaraCat's only role is paying the mint fee on Arc. On many other bridges you would need Arc-native USDC as gas before you could even claim your funds; here the relayer covers that mint gas for you, funded by $BRC trading fees. You sign only the approve & burn transactions in your own wallet — your keys never touch our server.

Tip: try a small amount of USDC first before bridging a larger one.
