PROTOCOL ENGINEERING
Custom Blockchain Development
Build secure, scalable, and purpose-built blockchain networks tailored to your business logic.
- Layer 1 & 2 Development: Build sovereign chains or scaling solutions using
Substrate,Cosmos SDK, orArbitrum Nitro. - Consensus & Validator Networks: Implement
Tendermint,HotStuff, or custom consensus for your specific throughput and finality needs. - Enterprise Integration: Seamless bridges and oracles for hybrid systems, connecting to traditional databases and APIs.
Deliver a production-ready mainnet in 8-12 weeks, not months. We handle the full stack—from cryptographic primitives to node infrastructure—so your team can focus on application logic.

PROVEN FRAMEWORK
Our Delivery Methodology
We deliver secure, scalable on-chain identity portals through a structured, transparent process designed for technical teams. Our methodology ensures predictable timelines, robust security, and seamless integration with your existing stack.
01
Architecture & Protocol Design
We architect your portal using battle-tested standards (ERC-725, Verifiable Credentials) and select the optimal protocol (Ethereum, Polygon, Base) based on your throughput, cost, and decentralization requirements. This foundational phase ensures long-term scalability and interoperability.

02
Secure Smart Contract Development
Our engineers write, test, and deploy the core identity logic in Solidity 0.8+ using OpenZeppelin libraries. Every contract undergoes rigorous unit and integration testing before deployment to mainnet or your chosen L2.

Frontend & API Integration
We build a responsive admin dashboard and user-facing portal with wallet connectivity (MetaMask, WalletConnect) and integrate secure APIs for credential issuance/verification. The stack is tailored to your needs (React/Next.js, Node.js).

Frequently Asked Questions
Get clear answers on timelines, security, and process for building your decentralized identity portal.
A production-ready MVP with core features like credential issuance, verification, and a basic user dashboard typically takes 6-10 weeks. This includes architecture, smart contract development, frontend integration, security audits, and deployment. Complex integrations with existing KYC systems or custom governance models can extend the timeline to 12-16 weeks. We provide a detailed project plan within the first week of engagement.
