FULL-STACK ENGINEERING
Custom Blockchain Development
End-to-end blockchain solutions built for scale, security, and rapid deployment.
- Protocol Design: Custom consensus (
PoS,PoA), tokenomics, and governance models. - Smart Contract Suite: Audited
Solidity/Rustcontracts forERC-20,ERC-721, and custom standards. - Node Infrastructure: Managed validator nodes, RPC endpoints, and indexers on
EVM,Cosmos, orSolana. - Integration Layer: Secure APIs, oracles (
Chainlink), and cross-chain bridges (LayerZero,Wormhole).
Deploy a secure, scalable mainnet in 6-8 weeks, not quarters. We handle the entire stack so your team can focus on product and growth.

Why Build With Our ZK Reputation Service
Deploy a production-ready, privacy-preserving reputation system in weeks, not months. Our service provides the cryptographic infrastructure, so you can focus on your application logic.
02
Gas-Optimized Verification
Our circuits are engineered for minimal on-chain verification costs. Deploy verifier contracts with 30-50% lower gas consumption than generic implementations, making on-chain reputation checks economically viable.

Lower Gas Costs
03
Audited Security
Every ZK circuit and smart contract undergoes rigorous security review. Our standard offering includes an audit from a top-tier firm like Spearbit or Code4rena, ensuring the integrity of your reputation logic.
04
Rapid Integration
Go from concept to production in 2-4 weeks. We provide a complete SDK, API endpoints for proof generation, and Solidity verifier contracts, abstracting away the complexity of cryptographic engineering.

05
Flexible Reputation Models
Support for on-chain (token holdings, transaction volume) and attested off-chain data (KYC status, credit scores). Design custom logic for gated access, loyalty tiers, or underwriting without locking into a single framework.
06
Scalable Proof Generation
Leverage our managed infrastructure with 99.9% uptime SLA for high-volume proof generation. Automatically scale to handle thousands of concurrent proof requests during token launches or airdrop events.

Frequently Asked Questions
Get clear answers on how we build, secure, and deploy custom zero-knowledge reputation systems for your platform.
A standard implementation takes 4-8 weeks from kickoff to mainnet deployment. This includes design, circuit development, smart contract integration, and security audits. Complex systems with custom on-chain logic or multi-chain support may extend to 12 weeks. We provide a detailed project plan with weekly milestones at the start.
