Andreessen Horowitzs crypto arm has published a new thesis on its investment in Arc, arguing that stablecoins are “no longer just a payment rail” but “the foundation of a new economic operating system for global finance.” In its essay, titled “The new stack for global finance: Stablecoins edition,” the firm describes stablecoins as the base layer of a modular stack where wallets, orchestration services and credit networks all plug into programmable dollars that move on public blockchains. a16z says stablecoins now rival legacy payment rails The data point a16z
