Arc is Circle's Layer 1 blockchain built for stablecoin finance. Fees are paid in USDC instead of a volatile gas token, blocks finalize in under a second with deterministic finality, and Circle-issued assets like USDC, EURC, and USYC move natively on the network. Arc is designed for payments and tokenized money that need final, predictable settlement.
