Use Cases

The SDK guide shows you how to use individual methods. This section shows you how to combine them to build real applications.

Choose Your Path

If you're building...	Start here	You'll learn
Web dashboard, portfolio UI	Frontend Applications	Data fetching patterns, display mapping, real-time updates
Indexer, analytics, data pipeline	Backend Services	Historical snapshots, event indexing, state tracking
Liquidation bot	Liquidation Bots	Account monitoring, health factor filtering, execution patterns

Quick Decision Guide

Need to display data to users in real-time? Start with Frontend Applications. You'll use marketRegister for cached data and compressors for fresh queries.

Need to collect and analyze historical data? Start with Backend Services. You'll index events and snapshot state at specific blocks.

Need to monitor accounts and execute on-chain actions? Start with Liquidation Bots. You'll filter accounts by health factor and use the Router for execution.

Prerequisites

Before diving into use-case guides, complete:

1. Setup - Install the SDK and initialize GearboxSDK

2. Reading Data - Understand marketRegister and basic queries

Common Foundation: Compressors

All use cases rely on compressors for efficient data fetching. Compressors aggregate on-chain data into single calls, reducing RPC overhead.

Compressor	Use Case
MarketCompressor	Pool state, credit manager config, token data
CreditAccountCompressor	Account queries with filtering and pagination
PriceFeedCompressor	Oracle status and update requirements

See Compressors Reference for the complete API.
