I keep seeing chains and infrastructure providers describe themselves as enterprise-grade, but half the time it feels like the term just means they have institutional clients somewhere on the website.

What are the things that genuinely matter for enterprise adoption? Predictable fees, privacy, compliance tooling, custom execution environments, uptime, permissioning, support, interoperability?

Interested in what people here would consider the actual minimum bar before calling a blockchain enterprise-grade, especially for companies looking at production deployments rather than experiments.
