# Mantra Zone Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of transaction fees distributed to liquidity providers on Mantra Zone. This metric is utilized to evaluate the economic incentives provided to liquidity sources that are utilized for asset swaps on the platform. For Mantra Zone, these fees are generated from swap operations and are paid directly to the liquidity pools. The accumulated fees are normalized and converted to USD using end-of-day price feeds.

## 2. Data sources

- **Blockchain events**: WebAssembly (`wasm`) events with an action of `execute_swap_operations` 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: Mantra Zone swap fee extraction

- **Purpose**: Extract swap fees from decentralized exchange transactions on Mantra Zone.
- **Logic**: WebAssembly (`wasm`) events are filtered where the contract address is equal to the Mantra Zone contract (`mantra1466nf3zuxpya8q9emxukd7vftaf6h4psr0a07srl5zw74zh84yjqagspfm`) and the action is `execute_swap_operations`. The `swap_fee` and `fee_token` values are parsed from the event attributes JSON payload using regular expressions.
- **Key fields**: `swap_fee`, `fee_token`, `block_timestamp`

### Component B: USD conversion and normalization

- **Purpose**: Normalize swap fees to decimal precision and convert them to USD.
- **Logic**: The extracted swap fees are joined with asset metadata to normalize the raw amounts by decimal precision. The normalized fees are then multiplied by end-of-day price feeds for the respective fee assets to determine the USD value.
- **Key fields**: `swap_fee`, `decimals`, `price_usd`

### Component C: Supply-side fee aggregation

- **Purpose**: Aggregate the daily supply-side fees for Mantra Zone.
- **Logic**: The USD-denominated swap fees are aggregated daily. These fees are designated entirely as supply-side fees, which are distributed directly to liquidity providers. Daily boundaries are defined using UTC timestamps.
- **Key fields**: `fees_supply_side`, `timestamp`
