rindexer_rust_playground

rindexer_rust_playground

Shows the broadest range of rindexer features in a single Rust project.

What it demonstrates

• Multi-contract: indexes 4 contracts (RocketPoolETH, a generic ERC20, UniswapV3Pool, USDT)
• Multi-network: Ethereum + Base
• Dual storage: PostgreSQL and CSV enabled simultaneously
• Event filtering: block-range-level event filtering
• Global contracts: defining a single contract (USDT) deployed across multiple chains

Contracts & Events

Contract	Network	Events
RocketPoolETH	Ethereum	Transfer, Approval
ERC20 (generic)	Ethereum	Transfer, Approval
UniswapV3Pool	Base	Swap
USDT (global)	Ethereum + Base	Transfer, Approval

Storage

PostgreSQL + CSV (both active at the same time)

Getting started

1. Copy .env.example to .env and configure your DATABASE_URL
2. Run docker-compose up -d to start the Postgress instance in the docker-compose.yml file
3. Run cargo run (defaults to starting both the indexer and GraphQL API), optionally you can add the flags: --indexer, to only index the data or --graphql, --port=<PORT> to start the GraphQL API.
4. You can access the GraphQL playground with your created data at http://localhost:3001/playground. Run the query in the UI:

   query Erc20TransfersPlusUniV3Swaps {
     allErc20Transfers(first: 3) {
       nodes {
         nodeId
         rindexerId
         contractAddress

         txIndex
         logIndex
       }
     }
     allUniswapV3PoolSwaps(first: 3) {
