What are the limits for how much USDC I can bridge?

You can currently bridge up to $10M USDC per transaction.

Why do fees vary between routes?

Different blockchains reach transaction finality at different speeds. On source blockchains where finality would typically take longer, the USDC Bridge (powered by Circle CCTP) can use Fast Transfer to complete your end-to-end transfer faster while source blockchain finality is still being confirmed in the background.

Providing this fast, end-to-end experience has different costs depending on the source blockchain.

You’ll always see the total fee before you confirm your transfer. For a breakdown of network-specific fees, see the CCTP Fees section in our Developer Docs.
