Ponder

A tool for indexing and querying blockchain data.

Ponder is a TypeScript framework for indexing blockchain data into PostgreSQL, providing a structured approach to processing on-chain events.

It offers type-safe database interfaces, built-in caching and syncing capabilities, and optimized query performance for blockchain applications.

Experience:

Set up Ponder indexing service with PostgreSQL for Opyn chain data on Arbitrum Testnet, enabling efficient data retrieval.

Opyn

Opyn is a decentralized options protocol on Arbitrum that raised $6.7M Series A funding led by Paradigm. Their main product Squeeth is a notable DeFi-native derivative. I implemented their initial trading interface and data indexing setup for Arbitrum Testnet using Next.js, Ponder, and viem/wagmi.
