Uniswap V2 Pair Tracker

Problem Description

A trading analytics platform wants to index all Uniswap V2 liquidity pool Swap events on Ethereum mainnet. The challenge is that Uniswap V2 creates new pair contracts dynamically through its factory contract at 0x5c69bee701ef814a2b6a3edd4b1652cb9cc5aa6f (deployed at block 10000835). Each pair contract emits Swap events when trades occur.

The factory emits a PairCreated event whenever a new pair is deployed:

event PairCreated(address indexed token0, address indexed token1, address pair, uint)

Each pair contract emits:

event Swap(address indexed sender, uint amount0In, uint amount1In, uint amount0Out, uint amount1Out, address indexed to)

The team needs to track every swap across all Uniswap V2 pairs, recording which pool the swap occurred in, the amounts, and the trader address. They also want to query this data through an API that supports filtering by pool address.
