# Fluid DEX Lite Fees Methodology

## 1. Overview

Fees measures the total value paid by traders to execute swaps through Fluid DEX Lite. These fees represent the cost of accessing liquidity provided by the protocol and are determined by the specific fee tier assigned to each trading pair. Fees are collected in the input asset for every trade and serve as a primary indicator of the economic activity and value generated by the Fluid DEX Lite product.

## 2. Data sources

- **Blockchain events**: `LogSwap` events from `FluidDexLite` contracts, covering Ethereum
- **External data**: End-of-day price feeds for traded assets

## 3. Step-by-step calculation

### Component A: Swap event parsing

- **Purpose**: Extract raw trade data from the blockchain.
- **Logic**: `LogSwap` events are parsed from `FluidDexLite` contracts. An internal decoding function is applied to the swap data field to extract the exchange identifier, the swap direction, and the adjusted input and output amounts.
- **Key fields**: `swapData` (encoded trade details), `transaction_hash`, and `address` (pool identification).

### Component B: Volume and fee tier mapping

- **Purpose**: Attribute trading activity to the correct assets and fee structures.
- **Logic**: Decoded trade events are joined with pool metadata to identify the specific assets (token0 and token1) and the applicable fee tier for the pool. The input asset is identified based on the swap direction. Trading volume is calculated by normalizing the input amount by the required decimal precision.
- **Key fields**: `dex_id` (pool identifier), `fee_tier`, and `token_address`.

### Component C: Fee calculation and USD conversion

- **Purpose**: Normalize fee values to a common currency for reporting.
- **Logic**: Fees are calculated by multiplying the input asset amount by the specific fee tier of the pool. The resulting fee amounts are multiplied by end-of-day price feeds to determine the USD value. Daily totals are aggregated using UTC day boundaries.
- **Key fields**: `amount`, `fee_tier`, and asset prices.
