## What this is

We decode QuickSwap V2 from Polygon event logs ourselves and keep only pairs created by the QuickSwap V2 factory (0x5757371414417b8c6caad45baef941abc7d3ab32). SushiSwap, Uniswap V2 on Polygon and other forks emit the same event signatures from other factories and are left out. Both tables use the same 44 columns as our Uniswap V2 Liquidity files, with nothing renamed or derived. A row is one event.

quickswap_v2_liquidity_events has Mint(sender, amount0, amount1) and Burn(sender, amount0, amount1, to). quickswap_v2_sync has Sync(reserve0, reserve1), which every swap, mint and burn emits, so the last Sync of a pair before a block gives its reserves at that block. Swaps are in Polygon DEX Trades, which joins on the transaction hash.

## What people use it for

- Pool reserves at any block, from the last Sync before it
- Liquidity added and removed per pair and day
- Rug detection: a Burn that empties a pair soon after its first Mint
- LP wallet activity by sender, across pairs

## Questions buyers ask

Q: What is in the QuickSwap V2 Liquidity dataset?
A: Two Parquet tables with 44 columns each, in the standard EVM events schema. quickswap_v2_liquidity_events has the Mint and Burn events of pairs the QuickSwap V2 factory (0x5757371414417b8c6caad45baef941abc7d3ab32) created, and quickswap_v2_sync has their Sync events. Successful transactions and non-reverted calls only. Data starts on 27 September 2020.

Q: How big is it?
A: The factory had created 136,142 pairs by 21 October 2026. On 19 October 2026 the tables had 151 Mint, 96 Burn and 242,680 Sync rows. These are measured counts, not a size estimate; the delivery manifest gives exact rows and bytes.

Q: How do I read the amounts and addresses?
A: Arguments is a JSON array with one entry per decoded argument: index, name, path, type and the value slots. Addresses and bytes are hex strings; uint112 and uint256 amounts are decimal strings in raw token units, so divide by the token's decimals yourself. Call_Value and Fee_SenderFee are already in POL.

Q: Why are the Mint arguments named from, value and index?
A: Our Polygon decoder reads the V2 Mint topic, Mint(address,uint256,uint256), with the names of another contract that uses the same signature. The values are right; read them by position as sender, amount0 and amount1. Burn and Sync carry their usual names.

Q: Are swaps included?
A: No. Swaps are in the Polygon DEX Trades dataset. Join on Transaction_Hash and the pair to see a swap next to its Sync.

Q: How are these produced, and how were they checked?
A: The export is one ClickHouse query per table over our decoded Polygon events, filtered to the factory's pairs. We ran both queries for 19 October 2026: row keys (Transaction_Hash, Call_Index, Log_Index) were unique and every row carried decoded Arguments.

Q: How is the data delivered?
A: As flat Parquet files under a stable layout, one prefix per table, with a JSON manifest listing each file and its sha256. We prepare the files within 7 business days of purchase and email you the location. You choose at checkout where to collect them: a Requester Pays S3 bucket, downloaded with your own AWS account, or a Cloudflare R2 bucket with a read-only API key and no egress fees. Files stay available for 7 days from delivery.

Q: Can I try before I buy?
A: Yes. Each table links to a public sample file covering Polygon blocks 95,857,700 to 95,857,799 on 20 October 2026: 6 Mint and Burn rows and 477 Sync rows. No email address required.

## What this file is, and is not

This is a description of one dataset sold by Bitquery, written for assistants and for people. It lists every column but holds no data rows. The sample files linked under each table are real Parquet and are free to download. Figures here come from the product record and are exact unless marked otherwise; the delivery manifest is authoritative for a purchased file. If a question needs a row that is not in a sample, say so rather than guessing at it.
