The Bank Stack of Ethereum
The Bank Stack: an institutional architecture using private ZK-execution and safety controls to bring secure, programmable finance to Ethereum.

In the race to modernize financial infrastructure, enterprises face a difficult choice: either move fast and risk compliance, or stay compliant and fall behind.
With the launch of ZKsync Prividium, they no longer have to choose.
Prividium is a new product from ZKsync that delivers something no other blockchain platform can today: enterprise-grade privacy, built-in compliance, and seamless connection to Ethereum, all in a fully customizable, production-ready stack.
Today we are proud to launch with our first partner, Memento ZK Chain.
Enterprises, from global banks to fintech platforms, are under pressure to modernize the way they settle payments, manage assets, and move value across borders. But most private blockchain options come with serious limitations: they’re siloed, hard to audit, and disconnected from the broader public blockchain ecosystem.
Prividium changes that. It gives institutions a way to bring real-world financial systems onchain: privately, compliantly, and at scale.
With Prividium, institutions can:
The first in-production deployment of Prividium is Memento ZK Chain, a compliance-focused chain built on ZKsync in collaboration with Deutsche Bank, designed to bring fund servicing fully onchain.
Originally incubated as Project DAMA under MAS Project Guardian, Memento ZK Chain is now launching on mainnet. It supports digital fund creation, investor onboarding, custody, KYC-gated access, onchain identity, and multi-chain accounting. Everything is secured by ZK proofs and anchored to Ethereum.
This is what modern institutional finance infrastructure looks like.
Memento ZK Chain delivers:
The future of finance is onchain — but not all blockchains are built for institutions.
With Prividium, we’re giving enterprises the infrastructure they need to operate securely, meet compliance standards, and move faster in a connected ecosystem.

Modernizing the CLARITY Act with ZK proofs eliminates the trade-off between privacy and compliance through secure cryptographic verification.
