How ARC AnyChain moves USDC
One source-wallet signature starts a CCTP v2 transfer. Arc App Kit coordinates the burn, Circle attests the message, and the Forwarding Service completes delivery on Arc Testnet.
Start a testnet transferPROTOCOL & CONTRACTS
How your USDC reaches Arc
ARC AnyChain orchestrates Circle CCTP v2 through Arc App Kit. Your wallet signs on the selected source; Circle completes the Arc side.
Connect & quote
Read source USDC and gas, validate the Arc recipient, then show every estimated fee before signing.
Authorize this transfer
EVM wallets increase USDC allowance by the required bridge debit—never an unlimited amount. Solana invokes its bridge program.
Burn & attest
App Kit starts the CCTP v2 burn. Circle observes the source message and produces its attestation.
Mint & forward
Circle's Forwarding Service submits the Arc message and delivers USDC without a destination-wallet signature.
