Decentralized Identity Credit Linkage

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists for your token, DeFi, or NFT project.

We architect and deploy custom Solidity/Rust smart contracts with formal verification and comprehensive audit trails. Our development process ensures your core logic is secure, gas-optimized, and upgradeable from day one.

Token Systems: Custom ERC-20, ERC-721, ERC-1155 with advanced features like vesting, staking, and governance.
DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with sub-second finality.
Enterprise Logic: Multi-signature wallets, asset bridges, and custom business logic with 99.9% uptime SLAs.

Move from concept to mainnet in as little as 2 weeks with a battle-tested development framework.

We provide full technical ownership and documentation, ensuring your team can maintain and iterate. Every contract undergoes peer review and testing against known attack vectors before deployment on Ethereum, Polygon, Solana, or other L1/L2 networks.

ARCHITECTURE

Core Components of Our DID Credit Linkage System

Our modular system integrates proven Web3 standards with enterprise-grade security to link real-world creditworthiness to on-chain identities. Each component is designed for regulatory compliance, seamless integration, and developer velocity.

W3C Verifiable Credentials Engine

Issue, verify, and manage tamper-proof credit attestations using W3C-compliant Verifiable Credentials. We implement selective disclosure and zero-knowledge proofs to protect user privacy while proving creditworthiness claims.

Client Value: Enables privacy-preserving KYC/AML and credit score sharing without exposing raw data.

Decentralized Identifier (DID) Registry

Sovereign identity management built on Ethereum and Polygon, supporting did:ethr and did:polygonid methods. Our registry provides a resilient, non-custodial anchor for user identities, separating credentials from identifiers.

Client Value: Eliminates vendor lock-in and gives users full control over their identity data and attestations.

Credit Oracle & Data Connector

Secure, permissioned oracle network that fetches and verifies off-chain credit data from traditional bureaus and alternative sources. Data is cryptographically signed and formatted into verifiable credentials on-chain.

Client Value: Bridges the gap between legacy financial data and DeFi, enabling underwriting for loans, rentals, and membership protocols.

Signed Feeds

Data Integrity

Compliance & Governance Module

Configurable rule engine for managing credential schemas, issuer accreditation, and revocation policies. Built-in support for GDPR right-to-erasure and regional regulatory frameworks.

Client Value: Reduces legal and compliance risk for fintechs entering regulated markets with automated policy enforcement.

Developer SDK & APIs

Comprehensive TypeScript/Go SDKs and REST APIs for seamless integration into existing applications. Includes libraries for credential issuance, presentation, and verification with full documentation and code samples.

Client Value: Cuts integration time from months to weeks, allowing your team to focus on core product logic.

Audit & Security Framework

All smart contracts and critical system components undergo rigorous audits by firms like Trail of Bits and CertiK. Our security-first design includes key management best practices and continuous monitoring.

Client Value: Mitigates smart contract risk and builds trust with users and regulators from day one.
