We build the data layer for Web3 applications. Subgraphs, custom indexers, and real-time event processing that make on-chain data queryable and useful.
Raw blockchain data is stored in transaction logs and state tries — structures optimized for consensus verification, not application queries. To build responsive Web3 applications, you need an indexing layer that processes blockchain events, computes derived state, and serves queries with sub-second latency. Arthiq builds this indexing infrastructure using The Graph protocol and custom indexing solutions.
Our indexing work powers DeFi dashboards that display real-time TVL and APY calculations, NFT marketplaces that support collection browsing and rarity filtering, DAO governance interfaces that track proposal history and voting patterns, and analytics platforms that aggregate on-chain metrics across protocols.
Whether you need a standard subgraph on The Graph protocol or a custom indexing service with specialized data processing, our team delivers indexing infrastructure that is accurate, performant, and reliable. We handle the complexity of chain reorganizations, event decoding, and data consistency so your application never shows stale or incorrect data.
The Graph is the standard indexing protocol for Web3, providing a decentralized network of indexers that process blockchain events and serve GraphQL queries. We develop custom subgraphs that map your smart contract events to queryable entities with the specific schema your application needs.
Our subgraph development includes schema design that optimizes for your query patterns, mapping functions that correctly decode and process every event type, derived fields that compute aggregates and relationships, and testing that validates data accuracy against known on-chain state.
We deploy subgraphs on The Graph's decentralized network for production reliability and on hosted services for development and testing. Our subgraphs handle complex event processing — multi-contract interactions, event ordering dependencies, and state reconstruction from event streams — with correct handling of edge cases like contract upgrades and event format changes.
Some applications need indexing capabilities that go beyond what subgraphs provide. We build custom indexing services for requirements like real-time WebSocket feeds, complex aggregation queries, cross-chain data unification, and integration with non-EVM data sources.
Our custom indexers are built in TypeScript or Rust with PostgreSQL storage, processing blockchain data through RPC and WebSocket connections. They handle chain reorganizations through confirmation depth tracking, maintain data consistency through transactional updates, and provide both REST and GraphQL APIs for data access.
For high-throughput requirements, we build indexers that process multiple chains in parallel, use efficient batch insertion patterns, and maintain materialized views for frequently accessed aggregations. Our indexers are designed for production operation with monitoring, alerting, and automatic recovery from transient failures.
Many applications need real-time on-chain data — trading platforms that display live prices, social platforms that show new posts as they are confirmed, and monitoring systems that detect events as they happen. We build real-time data streaming infrastructure using WebSocket connections and event-driven architectures.
Our streaming infrastructure processes new blocks within seconds of confirmation, decoding events and pushing updates to connected clients through WebSocket channels. Clients can subscribe to specific event types, contract addresses, or user addresses to receive only the updates they care about.
For applications that need historical data combined with real-time updates, we build unified APIs that serve historical queries from indexed storage and live updates from event streams. The transition between historical and real-time data is seamless from the client's perspective.
Multi-chain applications need data from multiple blockchains unified into a single queryable dataset. We build cross-chain indexing infrastructure that aggregates data from Ethereum, Polygon, Arbitrum, Base, Optimism, Solana, and other chains into unified entities.
Our cross-chain aggregation handles the complexity of different block times, finality models, and event formats. A user's portfolio aggregation across five chains requires processing five different event streams, normalizing data formats, and maintaining consistency when different chains have different confirmation depths.
Arthiq builds indexing infrastructure that makes on-chain data accessible, accurate, and fast. Our Singapore-based team has built indexing for protocols processing millions of events per day. Contact founders@arthiq.co to discuss your data infrastructure needs.
