ERC-20,ERC-721, staking, bonding curves, and automated market makers. - Multi-Chain Deployment: Deployments on Ethereum, Polygon, Arbitrum, Base, and other leading EVM chains.
- Full Audit Readiness: Code is structured with
OpenZeppelinstandards and includes detailed documentation for seamless third-party audit.
We deliver a complete, battle-tested contract suite in 2-4 weeks, from specification to mainnet deployment, giving you a secure foundation to build upon.
Core Technical Capabilities We Deliver
We architect and deploy production-ready, high-performance StarkNet systems that turn complex cryptographic concepts into reliable business logic for your credit scoring platform.
StarkNet Smart Contract Development
Production-grade Cairo 1.0 contracts for your ZK-NFT credit scoring logic, built with OpenZeppelin libraries and gas-optimized patterns for StarkNet's VM.
Zero-Knowledge Circuit Design
Custom ZK circuits (Cairo programs) that privately verify creditworthiness. We handle the complex math, so you get a verifiable, privacy-preserving scoring output.
On-Chain Data Oracle Integration
Secure, low-latency connections to on-chain data sources (DeFi activity, NFT holdings, transaction history) to feed your scoring algorithms with verifiable inputs.
ZK-NFT Minting & Management System
End-to-end system for minting, updating, and verifying non-transferable ZK-NFTs that represent a user's private credit score, with role-based access controls.
Prover Infrastructure & Optimization
Deployment and management of high-availability prover services to generate STARK proofs for your credit assessments efficiently, ensuring low latency and cost.
Security Audits & Formal Verification
Rigorous security review of your entire Cairo codebase, from business logic to ZK circuits, following industry best practices to mitigate financial risk.
Business Outcomes for Your NeoBank
Our StarkNet-based ZK-NFT credit scoring delivers concrete infrastructure improvements, measurable risk reduction, and new revenue streams.
Automated Underwriting Engine
Deploy a Cairo-based smart contract system that processes on-chain/off-chain data to generate credit scores, reducing manual review by 80% and cutting loan approval time from days to minutes.
Portable Credit Identity (ZK-NFT)
Issue non-transferable ZK-NFTs that act as a user's private, verifiable credit passport. Enables seamless credit history portability across DeFi protocols while preserving user privacy via zero-knowledge proofs.
Real-Time Risk Monitoring
Continuously monitor wallet activity and on-chain behavior to dynamically adjust credit limits and detect early signs of default, powered by Chainscore's proprietary risk algorithms.
Regulatory Compliance Framework
Built-in compliance modules for KYC/AML checks and audit trails. Our architecture ensures data handling meets global standards (GDPR, MiCA-ready) without compromising on-chain efficiency.
Capital Efficiency & New Products
Unlock capital by tokenizing credit portfolios or enabling peer-to-peer lending pools. Create new revenue streams with programmable loan products like flash loans for creditworthy users.
Developer-First Integration
Get production-ready APIs, comprehensive Cairo contract libraries, and dedicated technical support. Integrate our full credit stack into your existing neo-bank platform in under 4 weeks.

Our Development & Security Methodology
Our systematic approach ensures your StarkNet-based credit scoring system is built for scale, security, and regulatory readiness from day one.
Architecture & Design Review
We conduct a comprehensive technical deep dive to design a modular, upgradeable Cairo architecture that isolates core logic from scoring models, ensuring long-term maintainability and flexibility.
Secure Cairo Smart Contract Development
Our certified Cairo developers write, test, and optimize your core ZK-NFT contracts using established patterns (e.g., Account Abstraction for user ops) and OpenZeppelin Cairo libraries for security.
Rigorous Testing & Formal Verification
We implement a multi-layered testing strategy: unit tests with Protostar, integration tests on StarkNet testnet, and formal verification for critical financial logic to eliminate edge-case vulnerabilities.
Deployment & Mainnet Launch
We handle the full deployment pipeline: staging on testnet, configuring sequencers and provers for performance, executing the mainnet deployment, and verifying all contract interactions.
Ongoing Monitoring & Support
Post-launch, we provide real-time monitoring of your system's health, transaction success rates, and gas consumption, with SLAs for critical issue response and protocol upgrade support.
Frequently Asked Questions
Get clear answers about our StarkNet Cairo development process, security, and support for your on-chain credit scoring system.
From initial design to mainnet deployment, a standard implementation takes 4-8 weeks. This includes 1-2 weeks for requirements & architecture, 2-4 weeks for core Cairo contract development, and 1-2 weeks for auditing, testing, and deployment. Complex integrations (e.g., multi-chain oracles, custom scoring models) can extend this timeline. We provide a detailed project plan within the first week of engagement.
