Zero-Knowledge Proof Circuit Design for DeFi

We build bespoke zk-circuits for your specific DeFi logic, from private swaps and shielded liquidity pools to confidential yield calculations. Our circuits are optimized for minimal proof generation time and verification gas costs.

We specialize in deploying verifier contracts with extreme gas efficiency on EVM chains (Ethereum, L2s) and Solana. This directly reduces the operational cost for your users and protocol.

Every circuit undergoes rigorous internal review using formal verification tools and symbolic execution. We prepare comprehensive documentation for seamless third-party audits by firms like Trail of Bits or Zellic.

We implement the optimal proving system for your use case: Groth16 for smallest proofs on-chain, or Plonk/Plonky2 for universal setups and faster prover performance in complex DeFi applications.

Scale your protocol by aggregating thousands of transactions into a single proof. We design recursive circuits to batch operations, dramatically reducing per-transaction cost and blockchain load.

We don't just deliver circuits. We provide full integration support into your existing stack, including prover backend services, frontend SDKs, and monitoring tools for proof generation health.

We design circuits to minimize on-chain verification costs. Our custom arithmetic and constraint systems reduce gas fees by 30-60% compared to generic implementations, directly lowering your protocol's operational expenses.

Every circuit undergoes formal verification and peer review using industry-standard tools like Picus and Ecne. We implement multi-party trusted setups and zero-knowledge proofs to ensure your privacy logic has no cryptographic vulnerabilities.

Tailored circuits for DeFi primitives: private swaps, shielded liquidity provisioning, and confidential yield calculations. We encode your exact business rules—not approximations—into efficient ZK-SNARKs or STARKs.

Engineered for high throughput. Our circuits enable sub-second proof generation and verification, supporting thousands of transactions per second (TPS) for applications like private order book matching or batch settlements.

We handle the entire stack: from circuit design in Circom or Noir, to smart contract integration (Solidity, Cairo), and production deployment with monitoring. You get a complete, auditable ZK module, not just a circuit file.

Build privacy with accountability. We design circuits that enable selective disclosure and audit trails, allowing you to prove regulatory compliance (like AML) without exposing user data, future-proofing your protocol.

Custom circuits for private swaps, shielded liquidity provisioning, and confidential order-book matching. Built with gas efficiency and capital efficiency as primary constraints for real-world use.

All circuit logic follows formal verification principles where possible and undergoes rigorous audit cycles. We employ Circom and custom constraint systems with comprehensive test coverage against known vulnerabilities.
