Cross-chain USDC bridge
Move USDC across chains in a few taps. Bridge USDC between chains via Circle CCTP, your device signs the burn, the transfer settles itself.
Move USDC between supported chains using Circle’s CCTP. Your device signs the burn transaction; the transfer advances through Circle’s attestation and settles on the destination chain.
Same non-custodial shape as everything else: prepare on the server, sign on your device, track by public data.
Questions & answers
Cross-chain bridge: common questions
How does SpendTheBits bridge USDC across chains?+
It uses Circle's CCTP: your device signs the burn transaction and the transfer advances through Circle's attestation to settle native USDC on the destination chain. The server never signs, it only prepares and relays.
Are bridge fees transparent?+
Yes. The integrator fee is shown up front before you confirm, and every transfer is trackable in Activity.
