# DEX Pool Events

The chain DEX schema tables contain key events emitted by a protocol's liquidity pool.

The events table are hydrated with token decimals, prices and transaction-level details for ease of analysis.

Currently we support the following protocols and events.

### Protocol Coverage

<table><thead><tr><th width="135">Protocol</th><th width="265">Table</th><th>Events</th><th>Projects</th></tr></thead><tbody><tr><td>uniswap\_v2</td><td>dex.uniswap\_v2\_events</td><td>mint, swap, burn, sync</td><td>uniswap & uniswap forks (e.g. sushiswap)</td></tr><tr><td>uniswap\_v3</td><td>dex.uniswap\_v3\_events</td><td>flash\_paid, swap, flash, burn, mint, initialize, collect</td><td>uniswap & uniswap forks</td></tr><tr><td>uniswap\_v4</td><td>dex.uniswap\_v4\_events</td><td>Swap, Initialize, OwnershipTransferred, Transfer, ModifyLiquidity, OperatorSet</td><td>uniswap & uniswap forks</td></tr></tbody></table>

### Coming Soon

We're actively working on expanding our DEX pool event coverage to include other major protocols such as:

* Curve Finance

* Algebra

* PancakeSwap

* And more!

If you'd like to request support for a specific DEX protocol, please reach out to our team.

### Query Example

How to calculate quarterly liquidity pool deltas in USD for all uniswap v2 pools?

Steps:

1. calculate the liquidity changes in token amounts first

2. convert token amount to USD amount based on the end of quarter usd exchange rate

3. filter out noisy data (set limit of 5 billion for token liquidity change in a quarter)
