Circle's Arc Blockchain Launches Mainnet with USDC as Native Gas Token
Circle has launched the mainnet of its layer-1 (L1) blockchain Arc, designed for stablecoin payments and financial markets. The network uses USDC as its native gas asset and supports more than 20 fiat stablecoins.
Arc also offers Ethereum Virtual Machine (EVM) compatibility and deterministic sub-second settlement finality. Tokenized assets including BlackRock's BUIDL and Circle's USYC are available natively on Arc.
The launch follows the public testnet debut in October 2025, which saw participation from over 100 companies, including major financial institutions like BlackRock and Goldman Sachs.
