Regulatory ZK Proof for Cross-Chain Compliance
We engineer zero-knowledge proof systems that enable institutions to prove regulatory compliance (KYC, AML, transaction limits) for cross-chain transactions without revealing sensitive customer or transaction data.

overview
SECURE FOUNDATIONS
Smart Contract Development
Production-ready smart contracts built for security, scalability, and compliance.
- Full Lifecycle Development: From specification and
Solidity/Rustcoding to deployment and verification onEVMorSolanachains. - Comprehensive Audits: Every contract undergoes internal review and is prepared for third-party audits, ensuring vulnerabilities are eliminated before mainnet launch.
- Gas Optimization: We write efficient code to minimize transaction costs and enhance user experience, critical for high-frequency DeFi applications.
We deliver secure, auditable smart contracts that reduce your time-to-market and mitigate the risk of costly exploits.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your token, DeFi, or NFT project.
We architect, develop, and deploy custom smart contracts that form the immutable foundation of your Web3 application. Our team delivers battle-tested code for tokens (ERC-20, ERC-721, ERC-1155), DeFi protocols (lending, staking, DEXs), and DAOs, ensuring security and gas efficiency from day one.
We don't just write code; we engineer systems that hold and move value.
- Security-First Development: Code built with
Solidity 0.8+, following OpenZeppelin standards and industry best practices. - Full Audit Readiness: Contracts are structured for seamless review by top firms like ConsenSys Diligence or Trail of Bits.
- Gas Optimization: Every line is optimized for lower transaction costs and better user experience.
- Comprehensive Testing: Rigorous unit and integration testing with
HardhatorFoundrybefore mainnet deployment.
From a 2-week MVP for your token launch to complex multi-contract systems, we provide the technical backbone. Our process includes documentation, deployment scripts, and post-launch monitoring, so you can launch with confidence.

Frequently Asked Questions on ZK for Compliance
Get clear answers on how our Regulatory ZK Proof service works, from implementation to pricing and long-term support.
We deploy a custom Zero-Knowledge Circuit that generates cryptographic proofs of compliance rules (like OFAC sanctions screening) for cross-chain transactions. Your dApp submits transaction data to our prover, which generates a ZK-SNARK proof. This proof is verified on-chain before settlement, ensuring privacy—the verifier only sees the proof, not the underlying user data. We typically use Circom for circuit development and the Groth16 proving scheme for optimal gas efficiency on Ethereum and EVM-compatible chains.
