Unlock On-Chain Data With Geomi: Build Your Own Custom Indexer Without Code

Transform chaotic on-chain data into structured, queryable APIs in minutes. Geomi's no-code indexing eliminates backend complexity while giving you complete control over your data layer.

On-chain data is fundamentally unstructured – all transactions, events, and state changes are scattered across blocks with no easy way to query them. Without an indexer to decode and organize this chaos, even a simple dashboard or activity feed can demand weeks of heavy backend work.

This is where Geomi's no-code custom indexing steps in. It abstracts away backend complexity, enabling you to build sophisticated querying logic and define your own processors — all without writing a single line of code or managing any infrastructure.

The Problem: Data Chaos Meets Development Reality

Traditional blockchain data querying presents developers with a harsh choice: spend weeks building custom ETL pipelines and maintaining infrastructure, or settle for rigid, generic APIs that don't fit your specific needs.

Most Web3 applications need to:

  • Track specific contract events across multiple transactions
  • Aggregate data from different sources into coherent state
  • Provide real-time updates to users
  • Query complex relationships between on-chain entities

Building this from scratch means managing databases, writing complex parsing logic, handling blockchain reorganizations, and maintaining always-on infrastructure. It's a significant time sink that keeps teams from focusing on their core product.

The Geomi Solution: No-Code Custom Indexing

Geomi's no-code indexing transforms this equation entirely. Instead of choosing between complexity and flexibility, you get both: the power of custom indexing with the simplicity of a visual interface.

Here's how it works:

Define Your Processors: Use Geomi's intuitive interface to specify which on-chain events and state changes you want to track. No schemas, no database management, no deployment headaches.

Configure Data Transformation: Set up how raw blockchain events should be merged, aggregated, and structured. Define primary keys for merging events and create the exact data shape your application needs.

Get Instant APIs: Geomi automatically generates GraphQL endpoints that you can query directly from your frontend. Real-time updates, complex filtering, and nested relationships all work out of the box.

Scale Without Limits: As your application grows, Geomi's infrastructure scales automatically. No capacity planning, no database tuning, no performance optimization required.

Real-World Impact: DeFi Analytics Dashboard

The Challenge: A DeFi protocol on Aptos needed to provide users with real-time insights – total value locked, staking activity, transaction volume, and user-specific portfolio data – without building a heavy data backend.

Traditional Approach: The team would have needed to:

  • Set up event listeners for multiple smart contracts
  • Build database schemas for different event types
  • Write aggregation logic for calculating TVL and user balances
  • Handle real-time updates and cache invalidation
  • Deploy and maintain indexing infrastructure

Estimated timeline: 4-6 weeks of dedicated backend development.

Geomi's Approach: Using no-code custom processors, the team:

  • Configured event tracking for deposits, withdrawals, staking, and reward claims in minutes
  • Set up automatic aggregation rules to calculate real-time TVL and user balances
  • Defined custom processors to track user activity and generate portfolio insights
  • Received instant GraphQL APIs ready for frontend integration

The Outcome: The protocol shipped a comprehensive analytics dashboard in 3 days, not weeks. Users gained instant visibility into:

  • Personal portfolio performance and staking rewards
  • Protocol-wide metrics like TVL and volume trends
  • Transaction history with rich filtering and search
  • Real-time notifications for important events

The team avoided months of infrastructure maintenance while getting more powerful querying capabilities than they could have built in-house.

Building Apps with Custom Indexers

See how to integrate your custom indexer into a real application. This video demonstrates the complete workflow from setting up your indexer to building a functional dApp that leverages the indexed data for a rich user experience.

Beyond Basic Indexing: Advanced Capabilities

Geomi's no-code indexing goes far beyond simple event logging. Advanced features include:

Custom State Management: Define how events update application state over time. Track user balances, NFT ownership, governance votes, and complex protocol state without writing state management code.

Cross-Contract Queries: Easily combine data from multiple smart contracts into unified views. Build dashboards that span entire protocols or ecosystems.

Real-Time Processing: Events are processed and made available through APIs within seconds of being confirmed on-chain. No delays, no batch processing limitations.

Flexible Data Models: Configure exactly how your data should be structured. Create the relationships and aggregations that make sense for your specific use case.

Built-in Performance: All queries are automatically optimized. Pagination, filtering, sorting, and complex joins work seamlessly without manual optimization.

Integration Made Simple

Getting started with Geomi's no-code indexing requires no backend changes to your existing application:

  1. Design Your Processors: Use the visual interface to define what data you want to track
  2. Configure Transformations: Set up how raw events become structured data
  3. Test and Deploy: Validate your indexer with historical data before going live
  4. Integrate APIs: Connect your frontend directly to the generated GraphQL endpoints

Your existing smart contracts don't need any modifications. Your frontend code stays the same, except now it has access to rich, real-time data through simple API calls.

The Developer Experience Difference

Unlike other indexing solutions that require you to learn new query languages, deploy subgraphs, or manage infrastructure, Geomi focuses on developer experience:

  • Visual Configuration: Build indexers through an intuitive interface, not configuration files
  • Instant Feedback: See your data structure in real-time as you configure processors
  • Zero Maintenance: No servers to manage, no databases to optimize, no scaling concerns
  • Rapid Iteration: Modify your indexers and see changes instantly without redeployment

Performance and Reliability

Geomi's indexing infrastructure is built for production workloads:

  • Sub-second latency for real-time event processing
  • 99.9% uptime with automatic failover and redundancy
  • Unlimited scalability that grows with your application
  • Built-in monitoring with alerts and performance metrics

Technical Architecture Highlights

Behind the simple interface, Geomi runs enterprise-grade infrastructure:

Event Processing: High-throughput event ingestion with guaranteed ordering and at-least-once delivery Data Storage: Distributed, replicated storage optimized for both writes and complex queries
API Generation: Automatic GraphQL schema generation with intelligent query optimization Real-Time Updates: WebSocket support for live data feeds and notifications

Use Cases Across Web3

Geomi's no-code indexing powers diverse applications:

DeFi Protocols: Track liquidity, calculate yields, monitor governance, and provide user portfolio insights NFT Marketplaces: Index collections, track ownership history, calculate floor prices, and monitor trading activity
Gaming dApps: Track player progress, item ownership, leaderboards, and in-game economics DAOs: Monitor proposals, track voting patterns, calculate member contributions, and governance analytics Social dApps: Track user interactions, content creation, reputation systems, and social graphs
