We architect and deploy production-grade smart contracts that power your dApp's core logic. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.

  • Custom Logic: From ERC-20 tokens and ERC-721 NFTs to complex DeFi protocols and DAO governance systems.
  • Proven Security: Built with Solidity 0.8+ and OpenZeppelin libraries, following industry-standard patterns.
  • End-to-End Delivery: Includes comprehensive testing, deployment scripts, and documentation.

Reduce your time-to-market and technical risk with battle-tested code.

We deliver modular, upgradeable contracts designed for the long term. Each project includes:

  • Formal Verification: Key functions verified for correctness.
  • Gas Reports: Optimization to minimize user transaction costs.
  • Deployment & Verification: Hassle-free mainnet launch on Ethereum, Polygon, Arbitrum, or other EVM chains.

Core Capabilities of Our Identity Oracle Feeds

Chainscore's decentralized identity feeds deliver verifiable, real-world credentials on-chain with the security and performance required for production applications. We provide the infrastructure, so you can focus on building trustless user experiences.

01

Real-Time Credential Verification

On-chain verification of KYC/AML status, proof-of-humanity, and Sybil resistance signals. Integrate with our oracle to query verified identity states with sub-second latency, enabling compliant DeFi, airdrops, and governance.

02

Multi-Source Aggregation

Mitigate single points of failure by aggregating credentials from leading providers (e.g., Worldcoin, Gitcoin Passport, Civic) into a single, consensus-driven feed. Reduces reliance on any one vendor and enhances data integrity.

Privacy-Preserving Proofs

Leverage zero-knowledge proofs (ZKPs) to verify user attributes without exposing raw personal data. Our feeds support selective disclosure, allowing users to prove eligibility (e.g., >18, accredited investor) privately.

PROVEN FRAMEWORK

Our Delivery Methodology

We deliver production-ready decentralized identity feeds through a structured, transparent process designed for technical teams. Our methodology ensures security, scalability, and seamless integration from day one.

01

Architecture & Protocol Design

We architect your identity feed using battle-tested standards like ERC-725, ERC-1056 (EIP-1056), and Verifiable Credentials (W3C). This phase defines the data model, attestation flows, and on-chain/off-chain architecture for optimal performance and privacy.

Smart Contract Development & Audit

Our engineers write gas-optimized Solidity 0.8+ contracts for registry, verification, and revocation logic. Every contract undergoes a mandatory internal review and is prepared for third-party audits by firms like CertiK or OpenZeppelin.

We architect and deploy custom smart contracts that power your dApp's core functionality. From automated market makers and lending protocols to bespoke tokenomics and governance systems, we translate your requirements into gas-optimized, secure Solidity/Vyper code.

Every contract undergoes our multi-stage security review before deployment, significantly reducing the risk of costly exploits and protecting user funds.

  • End-to-End Development: Full lifecycle from specification and architecture to testing, auditing, and mainnet deployment.
  • Protocol Specialization: Expertise in ERC-20, ERC-721, ERC-1155, ERC-4626, and custom standards for DeFi, NFTs, and DAOs.
  • Guaranteed Outcomes: Delivery of audit-ready code with comprehensive test suites, documentation, and a clear deployment roadmap.
Decentralized Identity Verification Feeds

Frequently Asked Questions

Get clear answers about our technical approach, security, and delivery process for building secure, on-chain identity verification systems.

A Decentralized Identity Verification Feed is a secure, on-chain data pipeline that aggregates, validates, and streams verified identity attributes (like KYC/AML status, credential attestations, or reputation scores) from trusted sources to smart contracts. Our system typically works by:

  1. Ingesting data from compliant providers (e.g., KYC vendors, credential issuers).
  2. Processing & Signing the data off-chain using our secure, audited infrastructure.
  3. Publishing the signed verification results to a dedicated on-chain feed (oracle) that your dApp can query permissionlessly.

This creates a reusable, trust-minimized source of truth for identity checks across DeFi, DAOs, and regulated Web3 applications.
