Ponder is an open-source TypeScript framework for indexing EVM smart contract data into Postgres and serving it via GraphQL or SQL over HTTP. It offers a hot-reloading local dev server, end-to-end type safety without codegen, and deploys anywhere Node.js or Bun runs.

Use cases

• index smart contract events from any EVM chain into postgres
• build a custom API backend for a crypto app
• replace a Graph Protocol subgraph with faster custom indexing
• query onchain data over graphql or sql
• track token transfers and NFT registrations on ethereum
• serve custom blockchain data to a web or mobile frontend

When to choose

• you need custom, type-safe indexing of EVM contract events with a fast local dev loop
• subgraphs or RPC endpoints are too slow, inflexible, or expensive for your app
• you want to deploy an indexing backend on Node.js or Bun with horizontal scaling

When to avoid

• you only need simple off-the-shelf RPC reads without custom indexing logic
• your data lives on non-EVM chains
• you need a hosted indexing service with zero infrastructure management
