Circle is advancing its Arc Layer 1 ecosystem, pursuing a more efficient global FX workflow. The rollout introduces a real-time on-chain forex engine alongside multi-currency stablecoin interoperability, aimed at boosting liquidity, shortening settlement cycles, and reducing cross-border risk across crypto and traditional markets. This upgrade strengthens the role of Arc Layer 1 as a foundational infrastructure layer for digital asset ecosystems.

COINOTAG News, citing The Block, reported that the stablecoin-centered testnet went live on October 28 and attracted participation from more than 100 key players spanning traditional finance and crypto domains, including capital markets participants, banks, payments providers, and digital asset firms.
