Institutional adoption on @zksync has moved past the pilot phase and into operational deployment. To understand the scale, you have to look at the caliber of the entities involved:

The Cari Network: Five U.S. regional banks managing over $600B in deposits. It was founded by Eugene Ludwig, the 27th U.S. Comptroller of the Currency. This is not a "crypto experiment"; it is a strategic shift at the core of the U.S. banking system.
Deutsche Bank and BitGo: These institutions represent massive influence in global custody and transaction banking. They are choosing ZK-based infrastructure because it is the only architecture that solves the deadlock between public connectivity and private compliance.
35+ Institutions in Evaluation: This indicates a simultaneous, industry-wide pivot toward zero-knowledge proofs as the new standard for financial settlement.
$ZK is the only native asset of this entire system. It was launched with a "stem-cell" design, meaning its governance can decide to expand its economic function as the network matures. Right now, its primary role is providing the governance and gas needed for the ZKsync Gateway to bundle and settle these massive institutional volumes on Ethereum with mathematical certainty.
