According to the source, Arc is described as a stablecoin-focused blockchain from USDC issuer Circle that is intended to optimize native USDC settlement and compliance features for payments and tokenized assets (source: the source; source: Circle identifies itself as the issuer of USDC). The source does not provide a primary Circle announcement or technical documentation, so traders should await an official Circle press release or blog post before positioning around Arc (source: the source). For trading preparation, the source indicates the practical focus should be on USDC activity; traders can monitor USDC total supply and circulation changes that Circle reports in its transparency and attestation updates to gauge potential liquidity shifts once official details are released (source: the source; source: Circle transparency disclosures). The source also highlights that confirmation of Arc and initial integration details from Circle could influence where USDC liquidity deepens first across ecosystems, which is relevant for spreads and depth in USDC pairs on DEXs and CEXs once official information is published (source: the source).
