Stacks is reaching institutional-grade maturity through actual market integrations rather than theoretical roadmaps. The protocol has moved beyond pilot phases, establishing live connections with custody providers, liquidity venues, security platforms, and data infrastructure that institutions actively use. This represents a shift from promise to delivery—partnerships with the critical infrastructure layer that enterprise users depend on. The focus on real integrations across multiple institutional touchpoints suggests Stacks is positioning itself as production-ready infrastructure for serious market participants. Worth monitoring how these live connections translate into actual institutional adoption and transaction volume.
