IBCorLayerZero.
We deliver a complete, audited mainnet launch in 8-12 weeks, including documentation, monitoring dashboards, and a dedicated devops runbook.
Core Capabilities of Our GraphQL API Service
A unified, high-performance GraphQL endpoint that seamlessly fuses on-chain and off-chain data, designed for the reliability and scale demands of leading Web3 applications.
Business Outcomes: Why Unified APIs Drive Growth
A unified GraphQL API for on-chain and off-chain data isn't just a technical convenience—it's a strategic asset that accelerates product development, reduces operational overhead, and unlocks new revenue streams. Here's how our service delivers measurable business results.
Accelerate Time-to-Market
Eliminate the complexity of managing multiple data sources. Our unified schema lets your team ship features 2-3x faster by querying blockchain state, NFT metadata, and off-chain databases through a single, documented endpoint.
Reduce Engineering Overhead
Stop building and maintaining custom indexers, RPC aggregators, and data pipelines. We handle the infrastructure, monitoring, and scaling, freeing your senior engineers to focus on core product innovation.
Enhance Data Reliability & Security
Access verified, real-time data with enterprise-grade SLAs. Our infrastructure is built with multi-chain redundancy, automatic failover, and follows security best practices, ensuring your application's data layer is never a point of failure.
Unlock Advanced Product Features
Power complex queries that combine on-chain transactions with user profiles and market data. Enable features like personalized dashboards, cross-chain portfolio tracking, and real-time analytics that were previously too costly to build.
Optimize Infrastructure Costs
Replace the variable, unpredictable costs of running your own node infrastructure or using multiple paid APIs with a predictable, scalable subscription. Pay for unified queries, not redundant data fetching.
Future-Proof Your Stack
Our schema automatically incorporates new chains, protocols, and data standards. Integrate once and seamlessly access data from emerging networks like Berachain or Monad without rebuilding your data layer.

Our Development Process: From Schema to Production
A predictable, milestone-driven approach that de-risks your GraphQL API project and ensures on-time delivery of a secure, scalable data layer.
1. Discovery & Schema Design
We analyze your on-chain and off-chain data sources to architect a unified GraphQL schema. This phase defines the single source of truth for your application's data needs, preventing costly refactors later.
2. Resolver & Connector Development
Our engineers build performant resolvers that securely fetch and fuse data from blockchains (EVM, Solana), indexers (The Graph), and traditional APIs. We implement caching, batching, and error handling from day one.
3. Security & Performance Audits
Every API undergoes rigorous internal review for query complexity, rate limiting, and data validation. We conduct load testing to simulate production traffic and ensure scalability under peak demand.
4. Staging & Client Integration
We deploy to a dedicated staging environment with full observability. Your team receives SDKs and documentation to integrate the API, with our engineers providing direct support for a seamless handoff.
5. Production Deployment & Monitoring
Managed deployment to your cloud or our infrastructure with 99.9% uptime SLA. We implement real-time monitoring, alerting on latency spikes or data inconsistencies, and provide 24/7 operational support.
6. Ongoing Optimization & Scaling
Post-launch, we analyze query patterns and performance metrics to recommend optimizations. We handle scaling the infrastructure and schema evolution as your user base and data requirements grow.
