Ponder Template: Uniswap V3

This repository is a template for a Ponder project that indexes Uniswap V3 on Ethereum and Base.

Setup

PONDER_RPC_URL_1=
PONDER_RPC_URL_8453=

pnpm dev

Indexing logic

The ponder.config.ts file registers two contracts:

• UniswapV3Pool - Uses a factory address configuration to index Swap events emitted by any Uniswap V3 pool, starting from the latest block.
• UniswapV3Factory - Indexes PoolCreated events emitted by the factory contract and runs pool initialization logic, starting from the factory deployment block number.
