Back to collectionArc Moves From Private Buildout to Public Mainnet
Circle launched Arc with USDC fees, a curated validator set and more than 100 announced applications and builders.
Circle announced Arc’s public mainnet on September 16 after a private-mainnet phase. The Layer 1 uses USDC for fees and is designed for payments, foreign exchange, tokenized assets and software agents. Circle says more than 100 applications and more than 100 institutional and ecosystem builders were live or participating at launch, alongside a validator group drawn from financial and technology firms.
A public launch changes Arc from a roadmap item into operating infrastructure, but participation lists are not measures of sustained demand. The next evidence should be transaction quality, stablecoin liquidity, application retention and how the curated validator model performs under real load. Integrations announced for wallets, lending and agent platforms broaden distribution; they do not yet establish durable revenue or adoption.
