Custom Blockchain Development

End-to-end development of secure, scalable blockchain networks and protocols tailored to your business logic.

We architect and deploy custom blockchains and Layer 2 solutions that solve your specific business challenges. Our full-stack development covers everything from consensus mechanism design to node infrastructure and governance frameworks.

From a 4-week PoC to a production-ready mainnet, we deliver the foundational infrastructure for your decentralized application.

  • Core Protocol Development: Custom EVM-compatible chains, Substrate-based networks, and Cosmos SDK app-chains.
  • Layer 2 & Scaling: zkRollup and Optimistic Rollup implementations for high-throughput applications.
  • Full Lifecycle Support: Genesis block setup, validator onboarding, cross-chain bridge integration, and ongoing maintenance with 99.9% uptime SLAs.

Core Capabilities of Our KYC Protocol Development

We deliver production-ready, modular KYC infrastructure that integrates seamlessly with your application-specific blockchain, ensuring compliance without compromising on-chain performance or user experience.

01

On-Chain Identity Verification

Deploy a sovereign identity layer with zero-knowledge proofs (ZKPs) for privacy-preserving credential verification. Users prove compliance without exposing sensitive data, enabling regulatory adherence for DeFi, gaming, and enterprise use cases.

03

Cross-Chain Credential Portability

Implement W3C Verifiable Credentials that are portable across EVM and non-EVM AppChains. Our protocol uses decentralized identifiers (DIDs) anchored to your chain, reducing user friction in multi-chain ecosystems.

Technical & Commercial Questions

AppChain KYC Protocol Development FAQs

Answers to the most common questions from CTOs and founders evaluating custom KYC infrastructure for their application-specific blockchain.

Our standard engagement follows a 4-phase process: Discovery & Design (1 week), Core Development (2-3 weeks), Security Audit & Testing (1-2 weeks), and Production Deployment (1 week). For a standard AppChain KYC module, the typical end-to-end timeline is 5-7 weeks. We provide a detailed project plan with weekly milestones upon kickoff.
