- [Overview](/adapters/overview): Activity Indexer
- [Quickstart 🚀](/adapters/quickstart): Get the demo running end-to-end in minutes.
- [Time-Weighted Balances & Engine Flow](/adapters/time-weighted-balances): Core Concept
- [1. Overview & Schema](/adapters/tutorials/uniswap-v2-1-overview-and-schema): This adapter indexes Uniswap V2 pool activity. It tracks:
- [2. buildProcessor](/adapters/tutorials/uniswap-v2-2-buildprocessor): The `buildProcessor` function configures Subsquid to fetch only the logs we care about. This is crucial for performance - we want to minimize the amount of data we're processing while ensuring we capture all relevant events.
- [3. Redis Token Caching](/adapters/tutorials/uniswap-v2-3-redis-token-caching): Before we can decode swap events, we need to know which tokens are in the pool. Uniswap V2 pools have `token0` and `token1` addresses that we need to fetch from the contract. To avoid expensive RPC calls on every swap, we cache these addresses in Redis.
- [4. LP Tracking](/adapters/tutorials/uniswap-v2-4-lp-tracking): Track user LP token balances via `Transfer` events. This emits `balanceDelta` events that feed into the time-weighted balance (TWB) calculation system, enabling rewards based on liquidity provision duration.
- [5. Swap Tracking](/adapters/tutorials/uniswap-v2-5-swap-tracking): Coming Soon
- [6. Best Practices & Tips](/adapters/tutorials/uniswap-v2-6-best-practices): **Why it matters:** Catch misconfigurations early at runtime, before they cause data quality issues.
- [Uniswap V2 Adapter Tutorial](/adapters/tutorials/uniswap-v2-tutorial): This tutorial walks through the `uniswap-v2` adapter step-by-step so you can understand how it works and how to build similar adapters.
Each section is split into its own page for clarity.
- [Learn from Existing Adapters](/adapters/build-your-own/adapter-reference): This guide provides deep walkthroughs of each adapter, explaining how we reasoned about the design decisions and how to modify them for your protocol.
- [Deploy Your Adapter on Railway](/adapters/build-your-own/create-config): This guide explains how to encode your adapter configuration and deploy it to Railway.
- [Getting Started: Build Your Own Adapter (Clean Fork)](/adapters/build-your-own/getting-started): This guide helps you understand the Absinthe adapter architecture so you can safely modify existing adapters or create new ones for your protocol.
- [Build Your Own Adapter](/adapters/build-your-own): **Total time: ~2-4 hours**
- [How to Test Your Adapter](/adapters/build-your-own/testing-guide): This guide explains how to test and verify your adapter's correctness using manual CSV verification.
- [ERC20 Holdings Adapter](/adapters/build-your-own/adapters/erc20-holdings): **The simplest adapter — perfect starting point**
- [Morpho Markets Adapter](/adapters/build-your-own/adapters/morpho-markets): **Lending markets with supply/borrow tracking**
