[Circle's Public Blockchain Arc Suspected to Be Live, Not Yet Open for Testing] July 13 news: According to reports from crypto KOL @amathxbt and others, Circle's public blockchain Arc may have gone live privately. Cross-chain protocols LayerZero and LI.FI have already been deployed on the Arc network, but it has not been opened for community testing. According to public information, Arc is a public Layer 1 blockchain positioned as the 'Economic Operating System (Economic OS) of the Internet,' providing shared and composable infrastructure to support economic contracts, stablecoins, tokenized assets, and global market operations. In May of this year, Circle officially released the ARC whitepaper, outlining the design framework of ARC as the native coordination asset of the Arc blockchain network. The Arc public testnet is scheduled to go live in October 2025, with the mainnet expected to launch in the summer of 2026.
