Privacy and scalability are the future of Web3. I engineer highly secure Zero-Knowledge circuits using Noir and Barretenberg, allowing your protocol to verify complex off-chain logic on-chain without revealing sensitive user data.
Whether you need a proof-of-solvency model, privacy-preserving DeFi lending, or confidential identity verification, I deliver end-to-end ZK infrastructure ready for testnet or mainnet deployment.
What You Get:
- Custom Noir Circuits: Engineered to your exact protocol requirements (e.g., range checks, threshold verifications, Poseidon hashing).
- Proof Generation: Integration of Barretenberg (UltraHonk) to generate fast, client-side proofs (WASM) so private data never leaves the user's device.
- On-Chain Verifier Integration: A Solidity smart contract deployed to your target EVM chain that seamlessly calls the generated UltraVerifier to validate the ZK proof before state changes occur.
- Testing & Documentation: Complete test suites verifying both the circuit logic and the Solidity contract integration.
Tech Stack: Noir, Barretenberg (UltraHonk), Solidity, Foundry, TypeScript, Merkle Trees, Poseidon Hashing.
Why Work With Me: I specialize in the ZK-Solidity intersection. My recent implementations include a ZK-powered undercollateralized lending protocol (verifying credit scores off-chain) and a Merkle Sum Tree proof-of-solvency protocol inspired by PSE's Summa. I hold multiple Cyfrin Updraft certifications in Noir Programming, ZK Circuits, and ZK Fundamentals.
Requirements for the Buyer: Please provide a detailed breakdown of the logic that needs to be proven off-chain, the specific public/private inputs, and the target EVM network for the verifier contract.
