We architect and deploy custom smart contracts that are secure by design. Our development process integrates formal verification and automated testing from day one, ensuring your core business logic is resilient against exploits before mainnet launch.
Portable Identity Subgraph Development
Smart Contract Development
Secure, production-ready smart contracts built for your specific use case and audited for deployment.
Deliver a market-ready product in 4-6 weeks, from specification to audited deployment on your chain of choice.
- Protocol Development: Custom
ERC-20,ERC-721, staking systems, DAO governance, and DeFi primitives. - Security First: Built with
OpenZeppelinlibraries and patterns, followed by third-party audit coordination. - Full Lifecycle Support: From initial design and optimization to post-deployment monitoring and upgrade management.
What Our Portable Identity Subgraph Delivers
We build and manage production-ready subgraphs that power decentralized identity, giving your users control while ensuring your application has the reliable, high-performance data it needs.
Cross-Chain Identity Aggregation
A unified subgraph that aggregates identity attestations, credentials, and reputation scores from multiple protocols (e.g., ENS, Gitcoin Passport, Verifiable Credentials) into a single, queryable source of truth.
High-Performance Query Engine
Optimized GraphQL schemas and indexing logic for sub-second query response times, even for complex identity graph traversals, ensuring a seamless user experience.
Security-First Architecture
Subgraphs built with audited patterns, secure event handling, and data integrity checks. Includes monitoring for reorgs and malicious data to protect your application logic.
Managed Deployment & DevOps
End-to-end service from subgraph development to hosting on decentralized networks (The Graph) or our managed infrastructure, including CI/CD, versioning, and performance dashboards.
Custom Schema Design
We design entity relationships and GraphQL APIs tailored to your specific use case—whether it's Sybil-resistant governance, credit scoring, or gated community access.
Continuous Data Integrity
Automated health checks, indexing error recovery, and proactive alerts ensure your identity data layer remains accurate and available, eliminating manual oversight.
Build Faster, Scale Smarter with Unified Identity Data
Our Portable Identity Subgraph Development service delivers production-ready infrastructure, allowing your team to focus on core product innovation instead of data plumbing.
Pre-Built Identity Schemas
Deploy with standardized, extensible data models for wallets, NFTs, DAOs, and social graphs. Eliminate months of schema design and validation work.
Multi-Chain Data Aggregation
Unified identity views across Ethereum, Polygon, Arbitrum, and Base. Resolve user activity and assets from fragmented chains into a single subgraph.
Enterprise-Grade GraphQL API
High-performance, rate-limited endpoints with query optimization and caching. Ensure sub-second response times for complex identity queries under load.
Security & Audit Trail
Subgraphs built with OpenZeppelin patterns and undergo internal security review. All data transformations are verifiable and immutable.
Rapid Deployment Pipeline
From specification to hosted subgraph in under two weeks. We manage indexing, hosting, and monitoring so you can integrate and scale immediately.
Ongoing Protocol Support
We continuously update subgraph logic for new EIPs, token standards, and protocol upgrades. Your identity layer stays current without engineering overhead.

Our Development & Deployment Process
From initial architecture to mainnet deployment and ongoing monitoring, we manage the entire lifecycle of your Portable Identity Subgraph. This ensures a secure, high-performance solution delivered on time, every time.
Architecture & Specification
We design a subgraph schema optimized for your specific identity data model (SBTs, Verifiable Credentials, on-chain reputation). This includes defining entities, relationships, and indexing logic for maximum query efficiency.
Smart Contract Integration
Our engineers write and test the subgraph's mapping logic to accurately index events from your identity contracts (ERC-20, ERC-721, ERC-1155, custom). We ensure data integrity and handle complex cross-contract calls.
Testing & Optimization
We perform unit, integration, and load testing on a dedicated testnet deployment. We optimize indexing speed and GraphQL query performance to ensure sub-second response times under load.
Security Audit & Review
Every subgraph undergoes an internal security review focusing on mapping logic correctness, data sanitization, and denial-of-service resilience before any mainnet deployment.
Mainnet Deployment & Syncing
We handle the deployment to The Graph's decentralized network or a managed service. We monitor the initial sync to ensure it captures all historical data accurately and reaches 100% completion.
Monitoring & Maintenance
We provide ongoing monitoring for indexing health, query performance, and error rates. Our team is on call for upgrades, re-deployments for contract changes, and performance tuning.
Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for building a custom identity subgraph.
A portable identity subgraph aggregates and indexes on-chain identity data (like ENS names, social profiles, DAO memberships, and credential attestations) from multiple sources into a single, queryable API endpoint. You need one to build features like user profiles, reputation-based access, and personalized dashboards without the complexity of managing raw blockchain data. We've built subgraphs securing over $500M in TVL for identity and DeFi protocols.
