AppChain Indexer Development | Chainscore Labs

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy audit-ready smart contracts on EVM-compatible chains like Ethereum, Polygon, and Arbitrum. Our code follows OpenZeppelin standards and is battle-tested for DeFi, NFTs, and enterprise use cases.

Token Systems: Custom ERC-20, ERC-721, and ERC-1155 with minting, vesting, and governance modules.
DeFi Protocols: Automated Market Makers (AMMs), staking pools, and yield aggregators with optimized gas costs.
Enterprise Logic: Multi-signature wallets, supply chain trackers, and verifiable credential systems.

We deliver a fully tested codebase with comprehensive documentation in 2–4 weeks, accelerating your time-to-market.

Our process includes:

Formal Verification: Mathematical proof of critical logic correctness.
Multi-Audit Path: Reviews by internal experts and partnered third-party firms.
Upgradeability Patterns: Secure proxy architectures (TransparentProxy, UUPS) for future-proofing.

ENGINEERED FOR PERFORMANCE

Core Capabilities of Our AppChain Indexer Service

We build dedicated, high-performance indexers that transform raw blockchain data into structured, queryable APIs, accelerating your development and enhancing user experience.

Custom Data Schemas & Real-Time Indexing

We design and implement bespoke data models tailored to your AppChain's logic. Our indexers process blocks in real-time, ensuring your API reflects on-chain state with sub-second latency.

FROM INFRASTRUCTURE TO ADVANTAGE

Business Outcomes: Why a Custom Indexer is Critical

A generic, off-the-shelf indexer forces your application to adapt to its limitations. A custom-built indexer from Chainscore Labs is engineered to your AppChain's specific logic, delivering measurable performance and strategic advantages.

Real-Time Data Sovereignty

Eliminate reliance on third-party data latency. We build indexers that provide sub-second data availability directly from your chain, ensuring your application logic executes on the freshest state for trading, gaming, or DeFi operations.

< 1 sec

Data Latency

100%

Data Control

Unmatched Query Performance

Stop wrestling with complex, inefficient GraphQL queries. Our custom indexers are optimized for your specific data schema, delivering complex joins and aggregations in milliseconds, not seconds, directly impacting user experience.

Throughput Gain

Reduced Total Cost of Ownership

Avoid the hidden costs of scaling a generic service. A purpose-built indexer uses efficient data structures and pruning strategies, reducing cloud infrastructure costs by 40-60% at scale compared to adapting a one-size-fits-all solution.

Faster Time-to-Market for Features

Ship new product features without waiting for upstream indexer support. With full control over your data pipeline, you can iterate and deploy new indexed data views in days, not weeks, accelerating your development cycle.

Why a purpose-built indexer is critical for AppChains

Custom Indexer vs. Generic Solutions

Generic indexers often fail to meet the performance, flexibility, and cost requirements of dedicated application-specific blockchains. This comparison highlights the key differences.

Feature	Generic Indexer (The Graph, Covalent)	Chainscore Custom AppChain Indexer
Time to Deploy New Schema	Weeks (community subgraph review)	Days (direct deployment)
Query Latency	1 second (shared infrastructure)	< 100 milliseconds (dedicated)
Custom Business Logic
Data Ownership & Portability
Cost at Scale (10M reqs/day)	$2K-$5K/month (usage-based)	$500-$1.5K/month (predictable)
Chain-Specific Optimizations
Real-time Event Streaming	Limited (polling-based)
Support for Custom RPC Methods
Total Cost of Ownership (Year 1)	High (unpredictable scaling)	Low (fixed, predictable)
Guaranteed Uptime SLA	99.5% (shared)	99.9% (dedicated)

TRANSPARENT & PREDICTABLE

Our Delivery Process: From Specification to Production

A structured, milestone-driven approach that ensures your custom indexer is delivered on time, on budget, and to exact specifications. We provide clear visibility at every stage.

Phase 1: Discovery & Specification

We conduct a deep-dive technical workshop to map your AppChain's data model, query patterns, and performance requirements. Deliverable: A detailed technical specification document and project roadmap.

Technical Deep Dive

Frequently Asked Questions on AppChain Indexers

Get clear, technical answers on our development process, timelines, and support for your custom indexer.

A standard deployment for a production-ready, custom AppChain indexer takes 2-4 weeks from kickoff to mainnet deployment. This includes smart contract event parsing, GraphQL API development, and initial data validation. Complex requirements like real-time cross-chain data aggregation or advanced analytics can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the initial scoping call.
