# MANTRA Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the average fee users pay per transaction. It reflects how much it typically costs to use the network, incorporating both base transaction costs and application-layer fees from Mantra Zone. The metric is calculated by dividing the total daily fees collected across the ecosystem by the total daily transaction count.

## 2. Data sources

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

## 3. Step-by-step calculation

### Component A: Chain transaction fees

- **Purpose**: Calculates total fees paid for basic blockchain transactions, including transfers and smart contract interactions.
- **Logic**: Transaction fee and tip amounts are extracted from Mantra Chain and Mantra EVM records. For Mantra Chain, denominations are normalized based on a network migration at block 13,000,000: transactions prior to this threshold are adjusted by 6 decimal precision and priced using legacy asset metadata, while transactions from block 13,000,000 onwards are adjusted by 18 decimal precision and priced using current asset metadata. For Mantra EVM, gas fees are calculated as the product of gas used and the effective gas price, normalized by 18 decimal precision. All values are converted to USD using end-of-day price feeds for the respective assets.
- **Key fields**: `transaction_fee` and `transaction_tip` for Mantra Chain; `gas_used` and `effective_gas_price` for Mantra EVM.

### Component B: Mantra Zone trading fees

- **Purpose**: Calculates fees generated by trading activities on Mantra Zone.
- **Logic**: Smart contract event logs from the Mantra Zone contract are parsed to identify `execute_swap_operations` actions within `wasm` events. Three fee components—`burn_fee`, `protocol_fee`, and `swap_fee`—are extracted from the event attributes. Fee amounts are normalized by asset-specific decimal precision and converted to USD using end-of-day price feeds.
- **Key fields**: `burn_fee`, `protocol_fee`, `swap_fee`, and `fee_token` from event attributes.

### Component C: Transaction count

- **Purpose**: Counts the total number of unique transactions per day to serve as the calculation denominator.
- **Logic**: Distinct transaction hashes are counted per day across Mantra Chain and Mantra EVM. All transaction types, including transfers, smart contract interactions, and trading activities, are included in the daily volume.
- **Key fields**: `transaction_hash` for deduplication and daily counting.

### Component D: Final aggregation

- **Purpose**: Combines all fee and volume components to calculate the final average.
- **Logic**: Total daily fees from Mantra Chain, Mantra EVM, and Mantra Zone are summed to create a comprehensive view of ecosystem fees. This total USD value is divided by the combined daily transaction count from Mantra Chain and Mantra EVM. Safe division is employed to handle instances where the transaction count is zero. All data is aggregated using UTC day boundaries.
