Circle’s Arc chain may have quietly gone live before planned testnet

Crypto commentators said LayerZero and LI.FI appear to be deployed on Arc, even as Circle’s public roadmap points to an October 2025 testnet and summer 2026 mainnet.

Summary

Circle’s Arc chain may have entered a non-public launch phase, according to crypto KOL @amathxbt and others, who said LayerZero and LI.FI were already deployed despite no community test being opened. Public information describes Arc as a public Layer 1 (base blockchain network). Circle published the ARC white paper in May, while its stated roadmap schedules a public testnet for October 2025 and expects mainnet in summer 2026. If confirmed, the apparent early rollout would suggest infrastructure partners are being brought on before any broader public release.
