# Mantra EVM Supply-side fees Methodology

## 1. Overview

The share of transaction fees distributed to service providers on Mantra EVM is represented by the Supply-side fees metric. On Mantra EVM, these fees are represented by the base fees generated from transactions, which are allocated directly to network validators as compensation for securing the network. The metric is calculated by multiplying the gas used in each transaction by the block's base fee per gas. These values are normalized and converted to USD using end-of-day price feeds.

## 2. Data sources

- **Blockchain events**: Block and transaction data, covering Mantra EVM
- **External data**: End-of-day price feeds for the native asset

## 3. Step-by-step calculation

### Component A: Mantra EVM base fee calculation

- **Purpose**: The base fee for each transaction on Mantra EVM is calculated.
- **Logic**: Transaction data and block data are joined using the block number. For each transaction, the gas used is multiplied by the base fee per gas of the corresponding block to determine the base fee.
- **Key fields**: `gas_used`, `base_fee_per_gas`, `block_number`

### Component B: Mantra EVM USD conversion and aggregation

- **Purpose**: Calculated base fees are normalized, converted to USD, and aggregated daily.
- **Logic**: The calculated base fees are normalized by decimal precision. The normalized values are then multiplied by the end-of-day price of the native asset to convert them to USD. The USD values are aggregated on a daily basis using UTC day boundaries.
- **Key fields**: `base_fee`, `price_usd`, `timestamp`
