Multi-Chain Data Indexing
Index and aggregate data from Ethereum, Solana, Polygon, and other major L1/L2 networks into a single, unified GraphQL API. Eliminate the complexity of managing multiple RPC nodes and data pipelines.
Custom Schema Design
We design and implement bespoke data schemas tailored to your dApp's logic—from NFT market analytics to DeFi yield tracking. Define the exact entities and relationships you need.
High-Performance Query Engine
Execute complex queries with sub-second latency, even across millions of indexed events. Built with optimized Postgres and caching layers for consistent performance at scale.
Real-Time Event Streaming
Subscribe to live data feeds via WebSockets or webhooks for instant notifications on transactions, token transfers, and custom smart contract events. Power real-time dashboards and alerts.
Enterprise Security & Compliance
Deploy in your own VPC or use our SOC 2 Type II compliant infrastructure. All data pipelines include encryption at rest and in transit, with role-based access control (RBAC).
Managed Operations & Monitoring
We handle indexing health, performance tuning, and protocol upgrades. Get 24/7 monitoring, automated alerts, and dedicated engineering support to ensure zero data downtime.
Business Outcomes: Beyond Raw Data Access
Chainscore's indexing and query services deliver actionable intelligence, not just raw blockchain data. We transform on-chain activity into strategic assets that drive product innovation and operational efficiency.
Real-Time Risk & Compliance Monitoring
Automated on-chain surveillance for AML, sanctions, and smart contract vulnerabilities. Set custom alerts for wallet behaviors and transaction patterns to ensure regulatory compliance and mitigate exposure.
Personalized User Insights & Engagement
Build hyper-personalized DeFi dashboards and NFT discovery feeds by indexing user-specific on-chain history. Increase user retention and lifetime value with tailored recommendations and portfolio analytics.
Institutional-Grade Market Intelligence
Access aggregated, normalized data across DEXs, lending protocols, and NFT marketplaces. Power your trading algorithms, research reports, and investment theses with clean, queryable datasets.
Automated Treasury & Portfolio Management
Monitor multi-chain DeFi positions, yield farming strategies, and treasury assets in real-time. Automate reporting, rebalancing, and performance tracking for DAOs and institutional funds.
Enhanced Developer Velocity
Eliminate the complexity of running your own indexers. Our managed GraphQL and REST APIs provide reliable, schema-defined data, allowing your engineering team to focus on core product features.
Data-Driven Product Strategy
Leverage historical and real-time on-chain analytics to validate new features, identify market opportunities, and benchmark against competitors. Make strategic decisions backed by immutable chain data.
Build vs. Buy vs. Generic Indexer: A Data Strategy Comparison
Choosing how to source blockchain data is a critical technical and financial decision. This table compares the total cost of ownership, time investment, and risk profile of building your own indexer, using a generic public service, or partnering with Chainscore for a custom solution.
| Key Factor | Build In-House | Generic Public Indexer | Chainscore Custom Indexer |
|---|---|---|---|
Time to Production-Ready Data | 6-12+ months | Immediate | 2-6 weeks |
Initial Development Cost | $250K - $750K+ | $0 (setup) | $50K - $150K |
Ongoing Maintenance & DevOps | 2-3 FTEs | Managed by provider | Fully Managed SLA |
Data Customization & Logic | Full control | Limited to public schemas | Tailored to your dApp |
Query Performance & Latency | Your responsibility | Variable, shared resources | Guaranteed P99 < 100ms |
Data Freshness (Block Lag) | Configurable | Often 5-30 blocks | < 3 blocks guaranteed |
Security & Audit Trail | Your responsibility | Provider's responsibility | SOC 2 Type II compliant |
Support & Incident Response | Internal team only | Community / Basic | 24/7 Dedicated SRE |
Scalability for User Growth | Requires re-architecting | May throttle or fail | Auto-scales with usage |
Total Cost (Year 1) | $500K - $1M+ | $10K - $50K | $80K - $200K |
Our Delivery Process: From Schema to Production API
We provide a structured, client-aligned process to deliver a production-ready, high-performance data API. This ensures you get the exact blockchain data you need, on time and with enterprise-grade reliability.
1. Schema Design & Data Modeling
We collaborate with your team to define the precise data schema, entities, and relationships you need. This includes mapping on-chain events, contract states, and custom aggregations to your business logic.
2. Indexer Development & Deployment
Our engineers build and deploy custom indexers using The Graph Protocol or Subsquid. We handle subgraph/squid development, testing, and initial deployment to a dedicated, scalable infrastructure.
3. Performance Optimization & Tuning
We rigorously optimize query performance, indexing speed, and data freshness. This includes latency benchmarking, query cost analysis, and implementing caching strategies for sub-second response times.
4. Security Review & Production Readiness
Every deployment undergoes a final security and reliability audit. We verify data integrity, establish monitoring with Grafana/Prometheus, and set up automated alerts before handing over the production API endpoint.
6. Ongoing Management & Scaling
We manage infrastructure scaling, protocol upgrades, and schema evolution. You get a single point of contact for support, regular health reports, and proactive updates for new chain deployments.
Tailored for Enterprise & Web3 Use Cases
Our indexing and query infrastructure is engineered for the specific demands of high-throughput financial applications and complex decentralized systems.
Real-Time DeFi Data Feeds
Sub-second indexing of on-chain events for DEXs, lending protocols, and yield aggregators. Build dashboards, risk engines, and trading tools with live data from Uniswap, Aave, and Compound.
