Decentralized Identity API Gateways

Deploy and manage a unified API gateway that aggregates identity and social graph data from multiple blockchains, eliminating backend complexity and accelerating development.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

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.

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 OpenZeppelin libraries 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.

01

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.

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.

01

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.

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.
