LayerZero delivers native cross-chain messaging on Arc, Circle's new institutional chain, from day one. The integration lets issuers move assets onto the network and connects Arc to LayerZero's 170+ existing chains, extending liquidity and reach across DeFi. Issuer asset flows on Arc route through the protocol from genesis, making this a direct day-one adoption point for the network.

The day-one placement matters because issuer flows, the activity Arc is built to attract, pass through LayerZero's messaging layer rather than arriving later through a retrofit. Arc lists LayerZero among several non-exclusive interoperability providers, so traffic depends on what issuers and applications actually select once multiple options are live.

For the network, each new chain connected at launch compounds reach for the existing 170+ connected chains, since assets and messages can move between Arc and that set without additional bridges.
