Production-ready blockchain for regulated finance
Deploy Prividium™ with confidence. Keep data private, stay compliant, and anchor to Ethereum for unmatched security.
Prividium™
Private where it matters.
Connected where it counts.
Prividium™ is the only Ethereum-secured blockchain platform purpose-built for institutions that demand privacy, compliance, and full control of their data.
"At Memento, we're dedicated to transitioning traditional finance on-chain. Our work with Deutsche Bank on a ZK Chain based platform simplifies and accelerates asset tokenization and fund management reducing complexity and costs while ensuring compliance and privacy for the financial products"

The Prividium™ difference
Private Execution
Public Verifiability
Public Verifiability
Transactions execute privately
All activity runs inside your infrastructure, keeping sensitive data from leaving your environment.
Controlled disclosure
Regulators or partners see only the information they are authorized to access.
ZK proofs certify correctness
Every batch generates ZK proofs that attest to validity without exposing raw data.
Finality on Ethereum
Proofs are anchored to Ethereum, providing transaction finality with the strongest available security guarantees.Prividium™ is a full ZK-based blockchain that keeps data private within your infrastructure.
Designed for enterprises, Prividium™ offers user-level privacy, compliance, cross-chain connectivity, and Ethereum-grade security out of the box.
Privacy with public proofs
Prividium™ ensures that sensitive data never leaves your infrastructure. Transactions, counterparties, and balances remain private, while ZK proofs certify correctness without exposing raw information. This eliminates the risk of data leakage and ensures regulators, partners, and auditors can verify outcomes independently. Finality on Ethereum combines privacy with strong security guarantees, making the system private yet publicly verifiable.
Built-in compliance
Prividium™ combines role-based access controls with ZK proofs to make requirements such as AML and KYC enforceable and verifiable. Granular permissions allow only authorized parties to deploy contracts, interact with them, or view data. Selective disclosure supports bytecode verification, sanctions checks, and proof of reserves or circulating supply on demand. Compliance can be demonstrated without exposing confidential business data, aligning blockchain operations with regulatory expectations.
Enterprise control with scale
Prividium™ gives operators full authority over governance and transaction ordering. A single operator can enforce policies directly, while independent validators can optionally attest to each batch for added protection. Enterprises can also customize the chain, from defining a custom gas token to operating in a fully gasless mode for seamless user experience. The platform is designed for horizontal scalability, allowing multiple Prividium™ instances to run in parallel and meet any level of throughput demand.
Direct connectivity
Prividium™ chains connect natively to Ethereum and the ZKsync ecosystem via ZKsync Connect, providing enterprises with seamless connectivity. Assets and information move seamlessly without bridges or intermediaries, improving capital efficiency and reducing risk. Transactions inherit Ethereum finality, while new chains can be onboarded in minutes rather than months, eliminating governance overhead and simplifying enterprise expansion.

Faster, compliant global payments
Cross-border payments between regulated entities
Traditional cross-border settlements take days, rely on intermediaries, and expose sensitive data. With Prividium™, regulated institutions can transfer value directly between one another. Transactions settle in minutes, compliance checks are enforced on chain, and data stays private, removing costly intermediaries and delays.
Full lifecycle for digital assets
Digital asset issuance and lifecycle management
Issue, distribute, and manage digital securities or tokenized assets with end-to-end governance. From creation and onboarding investors through dividends, transfers, and redemption, Prividium™ enforces compliance automatically. Every action is auditable and anchored to Ethereum while operational details remain confidential.
Compliant markets, verified participants
KYC-anchored tokenized markets
Open new liquidity channels without regulatory risk. Prividium™ enables marketplaces where every participant is identity verified (KYC/AML) but trades are still peer to peer. This reduces counterparty risk, ensures compliance, and allows institutions to safely unlock liquidity across tokenized assets.
Secure cross-chain financial products
Atomic swaps and cross-chain finance between institutions
Institutions can move value instantly across chains without intermediaries. Prividium™ supports atomic swaps, ensuring both sides of a transaction succeed or none at all. Combined with interoperability in the Elastic Network, banks and enterprises can build new cross-border settlement systems and financial instruments that work across multiple chains securely and privately.
Real-time intraday liquidity
Intraday repo and secured financing
Repurchase agreements (repos) are a backbone of institutional funding, but intraday liquidity is constrained by manual processes and batch settlement. Prividium™ enables real-time intraday repo markets where collateral, cash, and settlement all move instantly and privately. Institutions can optimize treasury operations, reduce counterparty exposure, and free up capital throughout the trading day.
Frequently asked questions
Everything you need to know about Prividium™.
No. Only ZK proofs are posted to Ethereum. These proofs confirm correctness without revealing underlying data or transaction details.
No. Permissioned ledgers depend on consortium trust. Prividium™ uses ZK proofs so every block is automatically verifiable. Trust is built into the math, not the governance model.
ZK proofs guarantee that every block is correct, even if there's only a single sequencer. An operator can see and choose which Prividium™ transactions to include, but they cannot falsify results because invalid blocks will fail verification. This means censorship is possible today, but a malicious or invalid transaction cannot be executed.
Yes. Prividium™ lets regulators verify balances, flows, or specific fields using cryptographic proofs tied to the Ethereum-anchored state. In practice, operators could also provide offchain reports as they do today. The difference is that with Prividium™, regulators have the option to independently verify the data whenever they are ready to adopt the tooling.
Not yet. Today Prividium™ operates with a single sequencer. Decentralized sequencing is on the roadmap, which will allow multiple operators to share responsibility and reduce censorship risk. Each sequencer in that model will see the full data processed on Prividium™.
Add-ons like FHE or mixers only cover certain applications and often add heavy performance costs. They also make data private even from the operator, which creates compliance risks, as seen with mixers. Prividium™ is a full chain architecture with privacy, compliance, and interoperability built in from the base layer, ensuring confidentiality without breaking regulatory requirements.
Traditional bridges rely on third parties and introduce extra trust assumptions. Prividium™ uses Ethereum itself as the trust anchor, enabling native, trust-minimized interoperability without intermediaries. Learn more about interop.
No. The core stack is open source and independently audited. Enterprises can operate it themselves, work with Matter Labs for SLAs and enterprise support, or choose other hosting providers. There is no vendor lock-in.
Each Prividium™ chain sustains 10K+ TPS. Enterprises can deploy multiple chains in parallel to scale throughput as needed, without hitting a performance ceiling. These chains communicate seamlessly through native interoperability, so assets and data can move across them as if on a single network, while preserving privacy, compliance, and Ethereum-grade security.
