We architect and deploy custom smart contracts that are secure, gas-optimized, and maintainable. Our development lifecycle includes formal verification and third-party audits to mitigate risk before mainnet deployment.
Decentralized Identity API Gateways
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From tokenomics to governance, we translate your business logic into robust on-chain code.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms.
- Security First: Development with
OpenZeppelinlibraries and adherence to Consensys best practices. - Full Lifecycle: Audit preparation, deployment scripting, and upgradeability planning using Transparent Proxy patterns.
Core Capabilities of Our Identity Gateway
Our API-first gateway provides the essential building blocks for secure, scalable, and compliant decentralized identity integration, reducing development time from months to weeks.
SSI & Verifiable Credentials Engine
Issue, verify, and manage W3C-compliant Verifiable Credentials (VCs) and Decentralized Identifiers (DIDs). Supports JSON-LD and JWT proof formats for interoperability with major identity networks like ION and Sidetree.
Zero-Knowledge Proof Integration
Implement selective disclosure and privacy-preserving proofs using Circom and Noir. Enable users to prove claims (e.g., age > 18) without revealing underlying data, ensuring GDPR and privacy-by-design compliance.
Multi-Protocol Wallet Orchestration
Unified API for managing user interactions across MPC wallets, smart contract wallets (ERC-4337), and traditional EOAs. Handles session keys, gas sponsorship, and batch transactions for seamless UX.
Compliance & Audit Framework
Built-in tools for KYC/AML checks, credential revocation lists (CRLs), and immutable audit trails. Pre-integrated with providers for regulated DeFi, gaming, and enterprise onboarding.
High-Availability Gateway API
REST and GraphQL endpoints with 99.9% uptime SLA, global CDN caching, and automatic failover. Includes rate limiting, monitoring, and webhook support for event-driven architectures.
Business Outcomes for Your Team
Our Decentralized Identity API Gateway delivers measurable results that accelerate your product roadmap and reduce operational overhead. See the guaranteed outcomes for your engineering and product teams.
Accelerated Time-to-Market
Deploy a production-ready, secure identity gateway in under 2 weeks, not months. We provide pre-built integrations for W3C Verifiable Credentials, OIDC, and popular wallet providers, so your team can focus on core application logic.
Enterprise-Grade Security & Compliance
Built on Zero-Knowledge Proof (ZKP) primitives and audited smart contracts. Our architecture is designed for SOC 2 Type II readiness, providing the verifiable security posture required by FinTech and regulated enterprises.
Drastically Reduced Dev & Ops Costs
Eliminate the need for a dedicated 3-5 person team to build and maintain custom identity infrastructure. Our managed service includes 24/7 monitoring, automatic updates, and a 99.9% uptime SLA, cutting your total cost of ownership by over 60%.
Seamless User Onboarding & Scale
Support millions of users with sub-second authentication latency. Our gateway handles credential issuance, verification, and revocation at scale, enabling frictionless onboarding flows that convert 40% more users compared to traditional KYC.
Future-Proof Interoperability
Avoid vendor lock-in with our protocol-agnostic design. We ensure your identity layer works across Ethereum, Polygon, Solana, and other L2s, and complies with evolving W3C DID and Verifiable Credentials standards.
Actionable Identity Insights
Gain a unified view of user engagement across wallets and dApps with our analytics dashboard. Track credential adoption, wallet activity, and user journey metrics to inform product decisions and drive growth.
Build vs. Buy: Identity Data Infrastructure
A detailed comparison of the time, cost, and risk involved in developing a decentralized identity gateway in-house versus using Chainscore's managed API service.
| Factor | Build In-House | Chainscore API Gateway |
|---|---|---|
Time to Production | 6-12+ months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Ongoing Maintenance (Annual) | 1-2 FTE Engineers ($150K+) | Optional SLA from $30K/year |
Security & Audit Burden | High (Your team's responsibility) | Low (Pre-audited, battle-tested modules) |
Protocol Coverage | Limited to team's expertise | Ethereum, Polygon, Arbitrum, Base, Solana, more |
Feature Velocity | Slow (internal roadmap) | Fast (Automatic updates, new standards) |
Compliance & Standards | Manual implementation of W3C VC, DIDs | Built-in compliance with W3C, IETF, emerging regulations |
Developer Experience | Build from scratch; maintain SDKs, docs | Production-ready REST/GraphQL APIs, comprehensive SDKs |
Total Cost of Ownership (Year 1) | $300K - $550K+ | $55K - $105K |
Primary Risk | Technical debt, security vulnerabilities, delayed launch | Vendor lock-in (mitigated by open-source components) |
Our Delivery Process: From Specification to Production
We deliver production-ready Decentralized Identity API Gateways on a fixed timeline. Our proven, four-phase process ensures technical alignment, security, and seamless integration into your existing infrastructure.
Phase 1: Architecture & Specification
We conduct a technical deep-dive to define your DID method (e.g., did:ethr, did:key), credential schemas (W3C VC-DM), and integration points. You receive a detailed technical specification and project roadmap.
Phase 2: Core Gateway Development
Our engineers build the core API Gateway with issuer/verifier endpoints, credential status management, and secure key storage. Built with Node.js/Typescript, leveraging libraries like did-jwt-vc and @veramo/core.
Phase 3: Security Audit & Pen-Testing
Every gateway undergoes rigorous internal security review and optional third-party audit. We test for OWASP Top 10 vulnerabilities, key management flaws, and logic errors in credential flows.
Phase 4: Deployment & Integration Support
We deploy the gateway to your cloud (AWS/GCP/Azure) with full CI/CD pipeline, monitoring (Grafana/Prometheus), and 99.9% uptime SLA. Includes 2 weeks of integration support for your development team.

Frequently Asked Questions
Get clear answers on how our Decentralized Identity API Gateway service works, from integration to security and support.
Standard integration takes 2-3 weeks from kickoff to production deployment. This includes environment setup, credential schema configuration, and end-to-end testing. Complex requirements like custom attestation logic or multi-chain support may extend the timeline, which we scope during the initial discovery phase.
