Ponder Integration for Scaffold-ETH 2

Prerequisites

Check if ./packages/nextjs/scaffold.config.ts exists directly in the current working directory (do not search subdirectories). If it doesn't exist, this is not a Scaffold-ETH 2 project. Follow the instructions at https://docs.scaffoldeth.io/SKILL.md to scaffold it first. If it exists, continue directly with building.

Overview

Ponder is an open-source framework for blockchain application backends. It indexes smart contract events and serves the data via a GraphQL API. This skill covers integrating Ponder into a Scaffold-ETH 2 (SE-2) project.

For anything not covered here, refer to the Ponder docs or search the web. This skill provides the SE-2-specific integration knowledge, not a complete Ponder reference.

Ponder gets added as a new workspace at packages/ponder/. The key integration point is that Ponder reads deployedContracts and scaffold.config from the nextjs package, so it automatically knows about all deployed contracts without duplicating ABIs or addresses.

Look at the actual project structure and contracts before setting things up. Adapt to what's there rather than following this skill rigidly.
