We architect and deploy custom Solidity/Rust smart contracts for DeFi, NFTs, and enterprise applications. Our code follows OpenZeppelin standards and undergoes rigorous security audits before mainnet deployment.
Volition-Based Credit Scoring System Development
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms.
- Enterprise Logic: Multi-signature wallets, supply chain tracking, verifiable credentials.
- Full Lifecycle: From architecture and development to testing, auditing, and deployment.
We deliver audit-ready code in 2-4 weeks, with a focus on gas optimization and upgradability patterns like
EIP-2535Diamonds.
Core Technical Capabilities We Deliver
Our development process delivers production-ready, audited systems that integrate seamlessly into your existing financial infrastructure, ensuring compliance, security, and scalability from day one.
Custom Volition Logic Engine
We architect and deploy the core on-chain logic for your credit scoring model, implementing your proprietary risk algorithms as verifiable smart contracts. This ensures transparent, tamper-proof score calculations that users can cryptographically verify.
Multi-Source Data Oracle Integration
Secure, reliable ingestion of off-chain financial data (e.g., bank statements, transaction history) via decentralized oracle networks like Chainlink. We implement robust verification and aggregation layers to feed clean, attested data into your scoring model.
ZK-Proof Privacy Layer
Implement Zero-Knowledge proofs (using circom & snarkjs) to allow users to prove creditworthiness without exposing raw personal or financial data. Enables compliant scoring while preserving user privacy and meeting regulatory standards.
Cross-Chain Score Portability
Deploy your credit scoring identity as a portable, sovereign asset using cross-chain messaging protocols (e.g., LayerZero, Axelar). Allows scores and reputations to be utilized across EVM and non-EVM ecosystems, maximizing user reach.
Enterprise-Grade API & SDK
Production-ready REST APIs and developer SDKs (Python, JS) for lenders and partners to query scores, submit applications, and manage verifications. Includes comprehensive documentation, rate limiting, and dedicated support.
Security & Compliance Audits
End-to-end security review including smart contract audits by firms like Trail of Bits, penetration testing on APIs, and compliance checks for financial regulations. We deliver a certified audit report and a remediation plan.
Business Outcomes for Your Platform
We deliver a production-ready, secure, and scalable credit scoring system that directly impacts your bottom line. Here are the concrete outcomes you can expect.
Volition vs. Traditional & On-Chain Scoring
A technical breakdown of how volition-based scoring fundamentally differs from legacy and purely on-chain alternatives, highlighting key advantages for FinTech and DeFi applications.
| Scoring Factor | Traditional Credit Scoring | On-Chain Scoring | Volition-Based Scoring (Chainscore) |
|---|---|---|---|
Data Sources | Limited bureau data, bank history | On-chain transactions only | Multi-source: On-chain + verified off-chain data |
User Privacy & Control | None (data owned by bureaus) | Full transparency (all data public) | User sovereignty via zk-proofs & selective disclosure |
Developer Integration | Months of compliance & API work | Weeks, but limited utility | Days with our modular SDK & APIs |
Risk Model Accuracy | Moderate, lacks Web3 context | Low, misses off-chain identity | High, holistic financial portrait |
Regulatory Compliance | Built-in but rigid | Challenging (pseudonymity) | Designed for compliance (GDPR, GLBA-ready) |
Real-Time Updates | Batch updates (monthly) | Real-time (on-chain only) | Real-time hybrid data sync |
Implementation Cost | $200K+ annual licensing | $50K-$100K dev cost | From $75K one-time + optional SLA |
Time to Live API | 3-6 months | 4-8 weeks | 2-4 weeks |
Our Development & Integration Process
A structured, transparent approach to building and deploying your volition-based credit system, designed for security, speed, and seamless integration with your existing FinTech stack.
Discovery & Architecture Design
We conduct a deep-dive workshop to define your scoring logic, data sources, and on-chain/off-chain architecture. Deliverables include a technical specification and a detailed integration roadmap.
Smart Contract Development
Our team builds the core on-chain logic for your credit scoring algorithm, including verifiable computation and privacy-preserving attestations. All contracts follow OpenZeppelin standards and are optimized for gas efficiency.
Off-Chain Oracle & API Layer
We develop the secure oracle network and REST/GraphQL APIs that bridge traditional financial data (bank statements, transaction history) to your on-chain system, ensuring data integrity and real-time updates.
Security Audit & Penetration Testing
Every component undergoes rigorous internal review followed by an independent audit from a top-tier firm. We provide a final audit report and implement all recommendations before deployment.
Staging Deployment & Integration
We deploy the complete system to a staging environment that mirrors mainnet. Our engineers work side-by-side with your team to integrate the APIs and smart contracts into your application.
Production Launch & Monitoring
We manage the mainnet deployment and establish comprehensive monitoring for system health, oracle performance, and contract events. Includes 30 days of post-launch support and onboarding.
Proven Technology Stack & Protocols
Our volition-based credit scoring systems are engineered on battle-tested infrastructure, ensuring enterprise-grade reliability, security, and seamless integration with your existing financial workflows.
Formal Verification & Audits
Every system undergoes rigorous security review. We employ formal verification tools and partner with leading audit firms like Trail of Bits to deliver mathematically proven contract security.
Frequently Asked Questions
Get clear answers on our development process, security, and outcomes for building a custom, on-chain credit scoring system.
A volition-based credit scoring system is a decentralized protocol that allows users to selectively disclose their financial data to generate a credit score. Unlike traditional models that aggregate data without explicit consent, our systems give users control. We build using zero-knowledge proofs (ZKPs) and verifiable credentials to enable users to prove creditworthiness (e.g., "I have an income > $100k") without revealing the underlying transaction history. This shifts the paradigm from surveillance-based scoring to permissioned, privacy-preserving assessment.
