# ZKsync - Prividium (Privacy L2 for Ethereum)

## Fits with patterns

* [Privacy L2s](/patterns/pattern-privacy-l2s/)
* [Private Stablecoin Shielded Payments](/patterns/pattern-private-stablecoin-shielded-payments/)
* [Shielding](/patterns/pattern-shielding/)

## Not a substitute for

* General-purpose public DeFi infrastructure (focused on institutional use cases)
* Permissionless privacy solutions (designed for compliant institutional access)
* General-purpose Privacy rollups

## Architecture

* Permissioned RPCs
* Each Prividium manages their own private state and permission controls
* Prividiums uses the ZKsync Gateway for setllement, who ZK commit blocks on the Ethereum L1

## Privacy domains

* User-level privacy with selective disclosure for policy compliance
* Private order flow execution with public price integrity proofs
* Confidential real-world asset tokenization and settlement
* Cross-border payment privacy with cryptographic settlement

## Enterprise demand and use cases

Target segments include financial institutions tokenizing treasuries and fund shares, capital markets requiring private order flow, and enterprises needing cross-border settlement. Key use cases involve real-world asset tokenization, and institutional-grade payment infrastructure with compliance integration.

## Technical details

* Powered by Airbender RISC-V prover delivering subsecond block proofs on commodity GPUs with \~$0.0001 per transfer costs
* EVM-native development using Solidity, Hardhat, and Foundry without custom languages
* Includes passkeys, smart accounts, and session keys for institutional onboarding
* Integration with ZKsync Connect for interoperability across public and private systems.

## Strengths

* Comprehensive enterprise features including compliance, KYC/AML, and selective disclosure
* Efficient ZK Proving
* Modularity and interop accross Prividiums
* L1 as final settlement layer

## Risks and open questions

* Institutional focus may limit broader DeFi ecosystem adoption
* Compliance requirements could create barriers for permissionless innovation
* No technical specs published yet
