Onchain Privacy Infrastructure for Enterprises
Privacy Boost enables enterprises to operate confidential financial flows on public blockchains—performant and compliant enough for real payment and settlement systems.
Core Capabilities
Built for enterprise adoption
High-Throughput
Sustained throughput with sub-300ms proof generation. Built for payment-grade workloads requiring instant settlement.
Compliance Ready
Configurable compliance modules with selective disclosure. Privacy that works within regulatory frameworks.
Self-Custodial
Full self-custody for end users. No trusted intermediaries — users control their funds at all time.
The Process
How it works
A simple flow combining ZK proofs and TEEs for fast, private, and compliant transactions.
Deposit
Assets deposited into privacy layer, converted to private notes.
Transfer Request
Users sign with spending keys. Shared key derived between parties.
ZK Proof Generation
TEE Prover generates proof with compliance rules enforced.
On-chain Verification
Proof verified on-chain. Only result recorded, details hidden.
State Indexing
TEE Indexer reads state with viewing key, indexes encrypted data.
Instant Access
Parties view balances and history instantly. Third parties blocked.
Use Cases
Built for financial applications
Wallets
Balance visibility and transaction history remain exclusive to end users. No more exposing your full financial footprint on-chain.
Stablecoins
Confidential settlement for payment networks and merchant flows. Enable private stablecoin transfers at scale.
RWAs
Institutional-grade confidentiality for real-world asset tokenization. Protect positions and transaction activity.
Fintech
Privacy infrastructure that aligns with financial regulatory frameworks. Built for regulated financial applications.

import { PrivacyBoost } from '@privacyboost/sdk';
// Initialize the client
const pb = new PrivacyBoost({
network: 'ethereum',
rpcUrl: process.env.RPC_URL
});
// Connect wallet
await pb.connect(wallet);
// Make a private transfer
const tx = await pb.transfer({
to: recipientAddress,

});
// Check private balance
const balance = await pb.getBalance('USDC');FAQ
Frequently asked questions
Everything you need to know about Privacy Boost.
Privacy Boost combines ZK proofs with TEEs to achieve both strong privacy guarantees and high performance. This hybrid approach enables sub-300ms proof generation and 500+ TPS throughput—significantly faster than pure ZK solutions—while maintaining the same cryptographic security guarantees.
Privacy Boost provides dedicated audit view keys that can be issued to regulators or authorized auditors. These keys enable selective disclosure of specific transaction data without exposing information to unauthorized parties. Compliance modules can be configured for KYC, AML, and jurisdiction-specific rules.
Privacy Boost is designed for EVM-compatible chains. We currently support Ethereum mainnet and are expanding to other EVM chains including Polygon, Arbitrum, and Optimism. Contact us if you need support for a specific chain.
Users control their own spending keys at all times. The privacy layer operates non-custodially—no trusted intermediaries are involved in the transfer flow. Users sign transactions with their private keys, and the TEE prover generates ZK proofs without ever having access to user funds.
We typically complete a production-grade PoC in 4-6 weeks. The scope includes private transfers, balance and history queries, and audit view functionality. Most developers can get a basic implementation running in a day.
Privacy Boost supports any ERC-20 token. The system is particularly well-suited for stablecoins (USDC, USDT, DAI), tokenized RWAs, and governance tokens. When assets are deposited into the privacy layer, they're converted into private notes.
