FULL-STACK ENGINEERING
Custom Blockchain Development
End-to-end development of custom blockchains, dApps, and smart contracts tailored to your business logic.
- Custom L1/L2 Chains: Build purpose-built networks with
Substrate,Cosmos SDK, orEVMrollups. - Smart Contract Suites: Audited
Solidity,Rust, orMovecontracts for DeFi, NFTs, and governance. - Full-Stack dApps: Complete front-end (
React/Next.js) and back-end integration with wallet connectivity and indexing.
Deploy a custom EVM-compatible testnet in under 4 weeks, with a clear path to production and validator onboarding.
Our process includes formal verification, gas optimization, and comprehensive documentation, ensuring your chain meets enterprise security standards and is built for long-term evolution.

ARCHITECTURE
Core Components of Your Reputation Layer
We deliver a modular, production-ready reputation system built directly into your AppChain's state. Each component is designed for security, scalability, and seamless integration with your existing dApps.
01
On-Chain Reputation Registry
A dedicated, gas-optimized smart contract suite that acts as the single source of truth for user reputation scores and attestations. Built with upgradeability patterns and role-based access control for future governance.

STRATEGIC ADVANTAGE
Why Deploy a Dedicated Reputation Layer
Move beyond basic transaction history. A dedicated reputation layer transforms on-chain activity into a programmable, high-fidelity asset for your application's core logic.
01
Customizable Reputation Logic
Define scoring models specific to your app's needs—staking weight, governance participation, transaction volume, or custom on-chain behavior. We implement your logic as upgradable smart contracts.

Custom Layer vs. Shared Reputation Protocols
Compare the trade-offs between building a dedicated reputation system for your AppChain versus integrating a shared protocol. Choose the optimal path for your security, performance, and go-to-market needs.
| Architecture Factor | Build Custom Layer | Integrate Shared Protocol (e.g., EigenLayer) |
|---|---|---|
Time to Production | 8-16 weeks | 2-4 weeks |
Upfront Development Cost | $150K - $400K+ | $25K - $75K |
Protocol-Specific Logic | Full Customization | Limited to Provider Rules |
Security & Audit Burden | High (Your Responsibility) | Shared (Provider's Responsibility) |
Data Sovereignty & Portability | Complete Control | Vendor Lock-in Risk |
Cross-Chain Composability | Requires Custom Bridges | Native via Provider Network |
Ongoing Node Operations | Your Team Manages | Managed by Provider |
SLA & Uptime Guarantee | You Define & Enforce | Defined by Provider (e.g., 99.5%) |

Our Delivery Methodology
We deploy your AppChain-specific reputation layer using a proven, phased approach that minimizes risk and ensures a production-ready system from day one.
01
Phase 1: Architecture & Design
We conduct a deep technical assessment of your AppChain's consensus, transaction flow, and governance model to design a custom reputation scoring algorithm. This ensures the layer integrates seamlessly and provides meaningful, actionable insights for your dApps.

Phase 2: Core Engine Development
Our team builds the on-chain reputation smart contracts and off-chain indexer/API using battle-tested frameworks (e.g., Foundry, The Graph). We implement security-first patterns from OpenZeppelin and conduct internal audits throughout development.

Phase 3: Security & Audit
Every reputation layer undergoes a formal security audit by a top-tier third-party firm. We resolve all critical/high-severity findings before deployment and provide a public audit report to build trust with your users and partners.

Frequently Asked Questions
Common questions from CTOs and technical founders about deploying a custom reputation layer for your application-specific blockchain.
A standard deployment takes 2-4 weeks from kickoff to mainnet launch. This includes design, smart contract development, integration with your chain's consensus, and initial testing. Complex requirements like multi-asset staking or cross-chain attestations can extend this to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
