Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy custom smart contracts that form the foundation of your product. Our development process ensures security-first design, gas optimization, and audit readiness from day one.
Deliver a secure, scalable, and maintainable contract suite in 4-6 weeks.
ERC-20, ERC-721, ERC-1155, and bespoke token standards.OpenZeppelin libraries, comprehensive unit/integration testing, and formal verification where applicable.We architect and deploy production-ready ZK identity systems that enable anonymous user verification and subscription management, reducing your compliance risk and accelerating user onboarding.
Our delivery includes comprehensive audits of the entire stack: circuit logic, smart contracts, and issuer backend. We follow OpenZeppelin security patterns and provide a formal verification report.
Receive a custom TypeScript/React SDK for seamless frontend integration. Includes hooks for proof generation, wallet connection, and subscription status management, cutting your integration time by 80%.
Our ZK Identity for Anonymous Subscriptions service delivers concrete, measurable results that directly impact your product's security, compliance, and user growth. We focus on verifiable outcomes, not just technical features.
We implement battle-tested zk-SNARKs (e.g., Circom, Halo2) or zk-STARKs to verify user eligibility without exposing personal data. This ensures your subscription logic is private, verifiable, and trustless.
We architect and deploy W3C-compliant Verifiable Credential schemas tailored to your subscription rules (e.g., "Proof of Age > 18", "Proof of Country"). This provides a flexible, standards-based foundation for anonymous access control.
We deliver gas-optimized Solidity/Vyper smart contracts that verify ZK proofs on-chain. Contracts include upgradeability patterns and are built with OpenZeppelin libraries, ensuring secure and efficient subscription gating.
Receive a production-ready SDK (JS/TS) and REST API for proof generation, submission, and status checking. This enables your frontend to integrate anonymous subscriptions in days, not months.
Every deployment includes a foundational security review of ZK circuits and smart contracts, aligning with best practices. We ensure your system adheres to privacy-by-design principles for regulatory readiness.
We handle deployment to your chosen EVM-compatible network (Mainnet, Arbitrum, Polygon) and provide monitoring dashboards for proof success rates and contract health, ensuring operational reliability.

A structured, four-phase approach to deliver production-ready ZK identity systems. We focus on security, compliance, and seamless integration to get your anonymous subscription service live faster.
We design your system's core architecture, selecting optimal ZK circuits (e.g., Circom, Halo2) and on-chain verification contracts. This phase defines the privacy model, credential schema, and integration points with your existing stack.
Our cryptographers implement and rigorously test the zero-knowledge circuits. Every circuit undergoes internal review and is prepared for a formal security audit by firms like Trail of Bits or Spearbit to ensure mathematical correctness.
We deliver a developer-friendly SDK (TypeScript/Go) for your frontend and backend, handling proof generation, wallet interaction, and API calls. We integrate directly with your user database and payment systems.
We manage the deployment of verifier smart contracts to your chosen network (Ethereum, Polygon, Arbitrum) and provide monitoring dashboards. Includes 30 days of post-launch support and SLAs for critical updates.
Build and deploy secure, high-performance blockchain networks tailored to your business logic.
We architect and implement bespoke Layer 1 and Layer 2 solutions from the ground up. Our team handles consensus mechanisms, node infrastructure, and network governance, delivering a production-ready mainnet in 8-12 weeks.
Proof-of-Stake, Proof-of-Authority, or hybrid consensus.EVM, Cosmos SDK, or Substrate-based chains.Get clear answers on how our zero-knowledge identity service works, from implementation to security.
A standard integration takes 2-4 weeks from kickoff to production. This includes protocol design, smart contract development, frontend SDK integration, and security review. Complex requirements like custom proof circuits or multi-chain support may extend the timeline, which we scope during the initial consultation.
