# Data Completeness

### DEXs/AMMs 

For the time being, for every DEX/AMM that is added onto DexGuru, we currently index and display transaction data **only from the date/time they are implemented**. 

This means for all transactions (and its TX data) that have occurred before the date of the DEX/AMM implementation date, **will not be included** in transaction lists, aggregates/counts and charts that involve the pre-implementation time period.

{% hint style="info" %}
💡 We are working on indexing and back-syncing all historical transactions and transaction data for every DEX/AMM that is supported on DexGuru. 
{% endhint %}

For the time being, a complete list of DEXs dates and their added date are available for your reference at [Supported DEXs](/data/supported-dexs.md).

### Types of Transactions 

We only show swaps, mints, and burns from [Supported DEXs](/data/supported-dexs.md) 

Currently, we only support the following types of transactions:

1. **Swap** - an exchange of one token for another. 
   * Buy 
   * Sell 
2. **Mint** - adding liquidity to a liquidity pool. 
3. **Burn** - removing liquidity from a liquidity pool.
