Overview

As blockchain-based financial systems mature, privacy is increasingly becoming a baseline requirement for enterprise adoption. For applications handling payments, stablecoins, RWAs, and institutional treasury flows, exposing balances, counterparties, and transaction history on public ledgers creates immediate regulatory, business, and competitive risk. Public blockchains, however, are fundamentally designed for transparency, which becomes a blocker for financial applications that require confidentiality, fast settlement, and regulatory alignment. Many existing privacy solutions were not built with institutional requirements in mind. In practice, this often leads to low throughput, high latency, integration friction, and limited support for compliance controls. Privacy Boost enables enterprises to operate confidential financial flows on public blockchains—performant & compliant enough for real payment and settlement systems. By combining ZK with TEEs, Privacy Boost delivers sub-second private transfers designed for real-world financial applications. Its core capabilities include:
  1. High performant, self-custodial private transfers for payment- and enterprise-grade workloads
  2. Configurable, regulator-ready compliance modules with selective disclosure and auditability
  3. Drop-in SDK integration for wallets, stablecoins, RWAs, and fintech applications

​
Problem

As blockchain-based services move from experimentation into production, privacy is no longer optional. In many real-world use cases, it becomes a prerequisite for the service to function at all.
  • Wallets require balance visibility and transaction history to remain exclusive to end users
  • Stablecoin payment networks need confidentiality across settlement and merchant flows
  • RWA issuers must protect institutional positions and transaction activity
  • Fintech applications require privacy that aligns with financial regulatory frameworks
Despite these needs, existing privacy solutions face persistent limitations in enterprise environments:
  • High proof generation latency (5–20s)
  • Slow balance and history queries (often minutes)
  • Limited throughput (<20 TPS)
  • Lack of native compliance controls (KYC, AML, sanctions, auditing)
  • Poor mobile and in-application integration

​
Solution & Core Capabilities

Privacy Boost is designed to bring confidential transfers into production-grade financial systems, built around three core principles. 1. High-Performance Private Transfers
  • Strong privacy guarantees through encrypted metadata, unlinkable transfers, and zero-knowledge proofs
  • Sustained throughput of 3,000+ TPS, suitable for enterprise- and payment-grade workloads
  • Immediate transaction indexing, enabling fast balance and transaction history retrieval
2. Configurable Compliance Modules
  • Dedicated audit view keys for regulators and authorized auditors, enabling selective disclosure
  • Modular compliance components, including KYC, AML, and jurisdiction-specific rules
  • Full self-custody for users, while supporting institutional compliance requirements
3. Simple SDK-First Integration
  • SDK-first architecture compatible with wallets, stablecoins, RWA platforms, payment systems, and fintech applications
  • No browser-based proof generation required, including in mobile environments
  • Intuitive APIs such as transfer(), getBalance(), and getHistory(), abstracting away cryptographic complexity

Demo

Deposits, transfers, and withdrawals, as well as balance and transaction history queries, are processed instantly. When auditing is required, only authorized parties can access relevant information through a viewing key, ensuring selective and controlled disclosure.

How It Works (Simple)

image.png 0. Deposit: Assets are deposited into the privacy layer and converted into private notes. 1. Private Transfer Request: Users sign the transfer request with their spending keys and submits it to the TEE Prover. 2. ZK Proof Generation: TEE Prover generates a ZK proof within ~500ms while enforcing compliance rules. 3. Onchain Verification: The chain verifies the proof and records the transaction result on-chain. Amounts, balances, and counterparties remain hidden. 4. Encrypted State Indexing: The TEE Indexer securely reads on-chain state indexes encrypted metadata. 5. Instant State Access: Senders and recipients to immediately view balances and transaction histories, while third parties have no access to this information.
