ZK-Rollup Privacy-Preserving Contract Platforms
We build confidential smart legal agreement platforms on ZK-Rollups. Our solutions use zero-knowledge proofs to validate contract execution and compliance while keeping sensitive commercial terms private from unauthorized parties.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Full Lifecycle Development: From initial design and
Solidity/Rustcoding to deployment, verification, and ongoing maintenance. - Security as Standard: All code follows
OpenZeppelinbest practices and undergoes rigorous internal audits before external review. - Compliance-Ready: We integrate patterns for
ERC-20,ERC-721, and custom standards with built-in hooks for regulatory requirements.
Deliver a market-ready, audited contract suite in as little as 4 weeks, backed by a 99.9% uptime SLA for critical functions.

ENFORCE COMPLIANCE, MITIGATE RISK
Business Outcomes for Legal & Enterprise Teams
ZK-Rollup privacy platforms must satisfy stringent legal and regulatory requirements. We deliver the technical infrastructure that enables your legal and compliance teams to operate with confidence.
01
Regulatory-Compliant Data Provenance
ZK-proofs generate verifiable, immutable audit trails for all private transactions, meeting FINRA, MiCA, and GDPR requirements for data integrity without exposing sensitive information.

PROTOCOL ENGINEERING
Custom Blockchain Development
Build secure, high-performance blockchain networks and layer-2 solutions tailored to your specific business logic.
We architect and deploy custom blockchains from the ground up, delivering sovereign networks with sub-2-second finality and transaction costs under $0.001. Our approach ensures your application's unique requirements—not a generic protocol's limitations—dictate the architecture.
From private consortium chains for enterprises to high-throughput public L2s, we deliver production-ready networks in 8-12 weeks.
- Core Protocol Development: Custom consensus (
PoA,PoS), virtual machines, and governance modules. - Layer-2 & Scaling:
zkRollupandOptimistic Rollupdevelopment onEthereum,Polygon, andArbitrum. - Full Node Infrastructure: Managed
RPCendpoints, block explorers, and cross-chain bridges with 99.95% uptime SLA. - Security First: Every chain undergoes formal verification and audits by
Trail of BitsorCertiKbefore mainnet launch.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical specifics for building your privacy-preserving platform.
We follow a structured 4-phase methodology: Discovery & Architecture (1-2 weeks) to define specs and choose the optimal ZK stack (e.g., StarkEx, zkSync, Polygon zkEVM). Core Development (3-6 weeks) where we build and unit-test the rollup circuits and smart contracts. Internal Audit & Staging (1-2 weeks) for rigorous security review and testnet deployment. Mainnet Launch & Support (1 week) for deployment and monitoring. We provide weekly demos and use Jira/Linear for transparent sprint tracking.
