# Mantra Chain Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the typical cost incurred by a user per transaction on Mantra Chain. This metric is calculated by dividing the total fees collected by the total number of transactions processed over a specific period. Insight is provided into the affordability and economic cost of interacting with Mantra Chain and Mantra EVM, reflecting the supply and demand for block space across the ecosystem.

## 2. Data sources

- **Blockchain events**: `execute_swap_operations` actions from `wasm` events from Mantra Zone contracts, plus transaction records covering Mantra Chain and Mantra EVM
- **External data**: End-of-day price feeds for native assets

## 3. Step-by-step calculation

### Component A: Mantra Chain fee capture

- **Purpose**: To extract and normalize transaction fees from the native Mantra Chain environment.
- **Logic**: Transaction fees and transaction tips are extracted from transaction records. These values are summed per transaction to determine the total fee. Amounts are then normalized by decimal precision, with the normalization factor adjusted from 6 to 18 decimals for transactions occurring from block 13,000,000 onwards to reflect the v7.0.0 migration.
- **Key fields**: `transaction_fee` and `transaction_tip`.

### Component B: Mantra EVM fee capture

- **Purpose**: To calculate fees generated within the EVM-compatible layer of the network.
- **Logic**: Fees are calculated by multiplying the gas used by the effective gas price for each transaction. These values are normalized by decimal precision to account for the native asset's decimals.
- **Key fields**: `gas_used` and `effective_gas_price`.

### Component C: Mantra Zone fee extraction

- **Purpose**: To identify swap-related fees within the decentralized exchange.
- **Logic**: Fees are parsed from `execute_swap_operations` actions within `wasm` events emitted by Mantra Zone contracts. Specific fees including `swap_fee`, `protocol_fee`, and `burn_fee` are extracted from the event attributes.
- **Key fields**: `swap_fee`, `protocol_fee`, and `burn_fee`.

### Component D: Transaction volume aggregation

- **Purpose**: To determine the total number of unique transactions processed by the network.
- **Logic**: The total count of distinct transaction hashes is calculated daily for both Mantra Chain and Mantra EVM. The denominator for the average fee calculation is derived from these counts.
- **Key fields**: `transaction_hash`.

### Component E: USD conversion and metric derivation

- **Purpose**: To calculate the final average fee in a standardized currency.
- **Logic**: All collected fees are converted to USD using end-of-day price feeds, with the asset price source transitioning from OM to MANTRA at block 13,000,000. The total USD fee amount for a given day is divided by the total transaction count for that same period. The final average transaction fee is calculated for each UTC day.
