Circle launches Arc mainnet with USDC as native gas token

Circle’s Arc mainnet is live with USDC for transaction fees, support for more than 20 fiat stablecoins and links to over 20 blockchains.

USDC issuer Circle has launched the mainnet of Arc, a layer-1 (L1) blockchain targeting stablecoin payments and financial markets, particularly agentic transactions.

Arc uses USDC as its native gas asset and offers Ethereum Virtual Machine (EVM) compatibility and deterministic sub-second settlement finality, according to an Arc blog post on Wednesday.

The network supports more than 20 fiat stablecoins, including USDC, EURC, JPYC, KRW1 and TRYB, while tokenized assets including BlackRock’s BUIDL and Circle’s USYC are available natively on Arc. Arc also offers interoperability with more than 20 blockchains through Circle’s Cross-Chain Transfer Protocol (CCTP) and Gateway.
