The public blockchain Arc under Circle is suspected to have gone live, but has not yet been publicly tested

According to crypto KOL @amathxbt and others, Circle's public blockchain Arc may have been launched privately. The cross-chain protocols LayerZero and LI.FI have been deployed to the Arc network, but have not been publicly tested by the community.

According to public information, Arc is a public Layer 1 blockchain, positioned as the "Economic Operating System 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 white paper, outlining the design framework for ARC as the native coordinating asset of the Arc blockchain network. The Arc public testnet is set to launch in October 2025. The mainnet is expected to go live in the summer of 2026.
