What is CCTP?
Circle's Cross-Chain Transfer Protocol burns USDC on the source chain and mints it natively on the destination. No wrapped tokens.
Why bridge?
Arc testnet USDC is available from the Circle faucet. Bridge from Sepolia or Base if you already have testnet USDC there.
After bridging
Your USDC arrives directly in your wallet on Arc. Then deposit into the vault or start trading immediately.
