News linked to both this project and an event.
According to Fortune, Catena Labs—founded by Sean Neville, co-founder of Circle—has raised $30 million in its Series A funding round, led by Acrew Capital and a16z crypto, with participation from Breyer Capital, General Catalyst, and QED. Catena Labs focuses on developing tools that enable AI agents to conduct financial transactions securely. The company has applied to the U.S. Office of the Comptroller of the Currency (OCC) in New York for a national trust bank charter, seeking regulatory authorization to process payments and hold customer funds. Previously, in 2025, Catena Labs secured an initial $18 million financing round led by a16z crypto.
a16z Crypto published a post explaining its investment rationale for Arc, noting that stablecoins have evolved from crypto-native trading tools into the foundational layer of global financial infrastructure—and are now driving blockchain’s evolution from “application-layer finance” to a “system-level economic operating system.” Last year, stablecoin transaction volume reached approximately $9 trillion—placing it on par with global payment networks such as Visa and PayPal. The total supply of USD-pegged stablecoins has surpassed $270 billion. Cross-border payments, B2B settlements, and foreign exchange transactions are emerging as core use cases for stablecoins, positioning them increasingly as the “global capital flow upgrade layer.” a16z Crypto stated that existing blockchain infrastructure remains primarily geared toward crypto-native users and individual developers, lacking native support for large-scale institutional requirements. Its participation in building the ARC token ecosystem stems from the expectation that, as global finance gradually migrates on-chain, only a select few public blockchains will be capable of serving as the foundational bedrock for “on-chain economic systems.”
