Privacy Layer for Existing DeFi Protocols

Design and deploy a modular privacy overlay that integrates with established protocols like Uniswap and Aave. Offer users optional confidential transactions without requiring a fork.

overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built to your exact specifications.

We architect and deploy production-ready smart contracts that power your core business logic. Our development process is built for security and efficiency from the ground up.

  • Security-First Architecture: Contracts are built with OpenZeppelin standards, undergo multiple audit stages, and include comprehensive test suites.
  • Gas Optimization: We implement advanced patterns to reduce transaction costs by up to 40%, a critical factor for user adoption and protocol economics.
  • Full-Stack Integration: We deliver not just the contract, but the deployment scripts, verification, and frontend interaction libraries (ethers.js/web3.js).

We deliver a complete, audited contract suite in 2-4 weeks, from initial spec to mainnet deployment.

Our engineers specialize in:

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with advanced features like vesting, minting controls, and governance hooks.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms, and yield aggregators.
  • Enterprise Logic: Multi-signature wallets, custom oracles, and permissioned access controls for institutional use cases.

ENTERPRISE-GRADE PRIVACY

Core Capabilities of Our Privacy Overlay

Our privacy overlay integrates directly into your existing DeFi protocol, enabling confidential transactions without forking your codebase or migrating liquidity. We deliver measurable security and compliance outcomes.

01

Zero-Knowledge Transaction Shielding

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.

Proof Generation
256-bit
Security Level
02

Selective Disclosure & Compliance

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.

03

Gas-Optimized Integration

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.

Formally Verified Circuits

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.

A PROVEN, SECURE PATH TO PRODUCTION

Our Delivery Process: From Audit to Mainnet

We deliver a predictable, secure, and rapid deployment pipeline for your privacy layer integration, minimizing risk and accelerating your time-to-market.

01

1. Architecture & Threat Modeling

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.

2. Zero-Knowledge Circuit 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.

Frequently Asked Questions

Get clear answers on how we integrate privacy into your existing DeFi protocol, from timelines and costs to security and ongoing support.

We use a phased, non-custodial integration strategy. First, we deploy a parallel, audited privacy module as a separate smart contract suite. User funds remain in your original protocol; the privacy layer acts as a shielded intermediary using zero-knowledge proofs. We conduct extensive staging environment testing, including forked mainnet simulations, before a low-risk, opt-in production rollout. This ensures zero downtime for your existing users.
