Privacy Layer for Existing DeFi Protocols

Deploy ZK-SNARK circuits to obfuscate sender, receiver, and amount data on-chain. Maintains full composability with your existing liquidity pools and smart contracts.

Client Value: Enables confidential trading and lending to attract institutional capital and privacy-conscious users.

Built-in compliance layer allows users to generate auditable proof-of-solvency or transaction history for regulators or auditors, without revealing the full transaction graph.

Client Value: Meets evolving regulatory requirements (FATF Travel Rule, MiCA) while preserving user privacy by default.

Lightweight middleware that adds minimal overhead (< 20% gas increase) to your core protocol functions. No need to rewrite your core AMM or lending logic.

Client Value: Preserves user experience with low transaction costs and avoids protocol bloat, protecting your competitive fee structure.

All ZK circuits and privacy smart contracts are formally verified using tools like Circom and certified by third-party auditors (e.g., Trail of Bits).

Client Value: Eliminates smart contract risk in the privacy layer, protecting user funds and your protocol's reputation with verifiable security.

We conduct a comprehensive analysis of your existing DeFi protocol to design a privacy architecture that integrates seamlessly with your logic. This includes defining data flow, identifying privacy boundaries, and creating a formal threat model to guide secure development.

Our cryptographers implement custom zk-SNARK or zk-STARK circuits using Circom or Halo2. We focus on optimizing for proof generation speed and gas efficiency, ensuring your privacy features are performant and cost-effective on mainnet.

We develop and integrate the on-chain verifier and manager contracts using Solidity 0.8+ with OpenZeppelin standards. Every line of code undergoes our internal multi-stage review before being submitted for a formal, independent security audit.

We deploy the full privacy stack to a designated testnet (e.g., Sepolia, Holesky) and execute rigorous simulation of mainnet conditions, including stress tests, front-running resistance checks, and economic attack simulations.

We manage the phased mainnet deployment with fail-safes, provide real-time monitoring dashboards for proof verification and system health, and establish incident response protocols. We remain on-call for the critical first 72 hours post-launch.

We deliver comprehensive technical documentation, operational runbooks, and conduct training sessions with your engineering team to ensure full ownership and the ability to maintain and extend the privacy layer independently.
