# Mantra Zone Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute swap operations within Mantra Zone. This metric captures the economic value generated by the automated market maker through liquidity provider fees, protocol-level fees, and fees designated for asset burning. These costs are paid by users to facilitate asset exchanges and support the sustainability of the Mantra Zone ecosystem.

## 2. Data sources

- **Blockchain events**: `wasm` events associated with the `execute_swap_operations` action from the Mantra Zone contract (`mantra1466nf3zuxpya8q9emxukd7vftaf6h4psr0a07srl5zw74zh84yjqagspfm`), covering Mantra Chain
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Extraction of DEX swap operations

- **Purpose**: To identify and capture all relevant swap activities on the Mantra Zone contract.
- **Logic**: `wasm` events are parsed from the Mantra Chain blockchain. These events are filtered to include only those emitted by the Mantra Zone contract address and containing the `execute_swap_operations` action. The swap-related attributes are extracted from the event logs to identify the assets involved and the corresponding fee values.
- **Key fields**: `block_timestamp`, `event_attributes`, `event_type`

### Component B: Categorization of fee components

- **Purpose**: To isolate and aggregate the different types of fees collected during a swap.
- **Logic**: Three distinct fee values are extracted from the event attributes: the swap fee (allocated to liquidity providers), the protocol fee (allocated to the project treasury), and the burn fee (allocated for permanent removal of assets from supply). These three components are summed for each transaction to determine the total fee generated by the trade.
- **Key fields**: `swap_fee`, `protocol_fee`, `burn_fee`, `fee_token`

### Component C: Normalization and USD conversion

- **Purpose**: To standardize fee values across different assets into a uniform currency.
- **Logic**: Fee amounts are normalized by decimal precision based on asset metadata. The resulting values are multiplied by the corresponding end-of-day price feeds for each asset. All values are aggregated to a daily granularity using UTC day boundaries.
- **Key fields**: `fees`, `price_usd`, `decimals`
