# Mantra Chain Fees Methodology

## 1. Overview

Fees measures the total value paid by users to interact with MANTRA. This includes transaction fees and tips paid on Mantra Chain, gas fees paid on Mantra EVM, and swap-related fees (including protocol, swap, and burn fees) paid on Mantra Zone. These fees represent the total economic value generated by users to access the network's consensus and application layers.

## 2. Data sources

- **Blockchain events**: Transaction and tip data from Mantra Chain, gas usage and price data from Mantra EVM, and `execute_swap_operations` actions within `wasm` events from Mantra Zone contracts, covering Mantra Chain and Mantra EVM
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Mantra Chain transaction fees

- **Purpose**: Captures network-level fees and tips on the native Mantra Chain.
- **Logic**: Transaction fees and transaction tips are extracted from native transaction records. These values are summed to calculate the total cost per transaction. All amounts are normalized by decimal precision, with the normalization factor transitioning from 6 to 18 decimals at block 13,000,000 to reflect the v7.0.0 migration.
- **Key fields**: `transaction_fee`, `transaction_tip`

### Component B: Mantra Zone trading fees

- **Purpose**: Captures application-level fees from swap operations on the Mantra Zone decentralized exchange.
- **Logic**: `execute_swap_operations` actions are parsed from `wasm` events emitted by Mantra Zone contracts. Three specific fee components—`swap_fee`, `protocol_fee`, and `burn_fee`—are extracted from the event attributes. These components are aggregated to determine the total fee generated by each swap.
- **Key fields**: `swap_fee`, `protocol_fee`, `burn_fee`, `fee_token`

### Component C: Mantra EVM gas fees

- **Purpose**: Captures execution fees from the EVM-compatible layer.
- **Logic**: Transaction data is parsed to extract the gas used and the effective gas price for every execution. Fees are calculated by multiplying the gas consumed by the effective gas price. Amounts are normalized by decimal precision.
- **Key fields**: `receipt_gas_used`, `receipt_effective_gas_price`

### Component D: USD conversion and aggregation

- **Purpose**: Normalizes all fee components to USD for consistent reporting.
- **Logic**: Fees from Mantra Chain and Mantra EVM are converted to USD using end-of-day price feeds for the native assets. For Mantra Chain, the price feed used for conversion is transitioned from the legacy asset to the migrated native asset at block 13,000,000. Mantra Zone fees are mapped to their respective asset addresses and converted using corresponding end-of-day price feeds. All components are aggregated by product and day using UTC day boundaries. Fees are then summed to provide the total project-level metric.
