In 2025, blockchain ecosystems have expanded across multiple categories of chains like public chains, Layer2/Layer3 rollups, appchains, Avalanche L1s, etc. With this growth comes an explosion in on-chain data. And hence an effective indexing of blockchain data has become mission-critical: it transforms raw, immutable ledger data into actionable, rapidly-queryable information that is the foundation of modern dApps, analytics dashboards, regulatory reporting, and more.

This article outlines the latest best practices and innovations for blockchain data indexing in 2025, and how Traceye makes it easy for anyone to index their chains.

Modern applications — especially in DeFi, gaming, and real-time analytics — demand minimal lag between blockchain events and their appearance in indexed data stores. Rapid index backfilling and minimal query latency are imperative for delivering a seamless and competitive user experience.

Traceye offers:

• Ultrafast index backfilling at up to 5x industry speed, ensuring your dApp or analytics dashboard is always up-to-date

• More than 50% reduction in data lag compared to conventional solutions

• Seamless multi-protocol support (Ethereum L2/3, Avalanche, Cosmos SDK, appchains, rollups), handled from a single pane of glass

Reliable uptime and resilience to chain reorganizations are necessary for indexers powering critical workflows and business processes. Indexing interruptions or failures can lead to stale data, missed opportunities, or compliance risks.

Traceye offers:

• SLA-backed 99.99% uptime and continuous infrastructure monitoring

• Automatic handling of chain re-orgs and synchronization, ensuring indexer consistency

• Choice between dedicated or shared indexers to balance control, cost, and resilience

Complex blockchain environments require transparency into infrastructure health, query volumes, resource allocation, and performance bottlenecks. Real-time analytics and robust dashboards are essential for efficient scaling and troubleshooting.

Traceye offers:

• Comprehensive dashboards for monitoring CPU, RAM, storage, and query throughput

• Automated logs and resource utilization tracking on every indexer node

• Drill-down analytics and actionable insights for continuous optimization

Blockchain data grows exponentially, so best-in-class indexers implement smart data retention: pruning obsolete records, focusing on what’s mission-critical, and storing only the required historical snapshots.

Traceye offers:

• Automated pruning modules for both ledger and indexed data (“Plus” feature), optimizing for storage and query speed

• Custom entity schemas to precisely match business, analytical, and compliance needs

• Unlimited subgraphs, queries, and throughput to ensure scalability as requirements change

Modern decentralized applications and business systems need instant, programmable access to indexed blockchain data — supporting both customized query interfaces and real-time event notifications.

Traceye offers:

• Comprehensive GraphQL APIs and one-click Token/NFT APIs (ERC20/721/1155 standards)

• Webhook integrations for real-time updates, notifications, and event-driven automations

• Direct database access for advanced analytics, compliance, and reporting workflows

As indexed data increasingly underpins financial apps, asset management, and enterprise workflows, safeguarding sensitive blockchain data is paramount. Security and privacy must be embedded in every layer of the indexing solution.

Traceye offers:

• Enterprise-grade encryption, battle-tested infrastructure, and secure API access for all indexer nodes

• Permissioned and private chain indexing (e.g., Hyperledger Besu, OP Stack permissioned chains), so sensitive data and business logic remain confidential and compliant

• Role-based access and schema customization to minimize data exposure and enforce least-privilege best practices

Zero-friction deployment, subgraph migration, and managed maintenance are key to accelerating time-to-market for both new and existing projects.

Traceye offers:

• One-click setup for appchains, rollups, subgraphs, and migrations from other platforms

• Complimentary subgraphs for development with simple scaling up to enterprise grade

• End-to-end support, including consulting for custom analytics, subgraph design, and data QA
