# MANTRA Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of transaction and protocol fees that is distributed to service providers within the MANTRA ecosystem. These fees are distributed to validators securing Mantra Chain and Mantra EVM, as well as liquidity providers on Mantra Zone. This metric is utilized to assess the economic incentives and compensation distributed to the infrastructure and liquidity providers of the network.

## 2. Data sources

- **Blockchain events**: Transaction records and smart contract execution events from Mantra Chain, and block headers and transaction receipts from Mantra EVM
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Mantra Chain transaction fee calculation

- **Purpose**: Calculate the transaction fees paid to validators on Mantra Chain
- **Logic**: Transaction fees and tips are extracted from transaction records on Mantra Chain. Prior to the V7.0.0 upgrade (block 13,000,000), fees are denominated in `uom` and normalized by decimal precision. Post-upgrade, fees are denominated in `amantra` and normalized by decimal precision. The daily sum of these transaction fees is aggregated for Mantra Chain.
- **Key fields**: `transaction_fee`, `transaction_tip`, `block_height`, `block_timestamp`

### Component B: Mantra Zone swap fee extraction

- **Purpose**: Extract swap fees distributed to liquidity providers on Mantra Zone
- **Logic**: Smart contract execution events are parsed for the `execute_swap_operations` action on Mantra Chain. The `swap_fee` is extracted from the event attributes. The fee amounts are normalized by the respective asset's decimal precision and aggregated daily.
- **Key fields**: `event_attributes`, `block_timestamp`, `fee_token`, `swap_fee`

### Component C: Mantra EVM base fee calculation

- **Purpose**: Calculate the base fees distributed to validators on Mantra EVM
- **Logic**: Block headers are parsed to extract the base fee per gas, and transaction receipts are parsed to extract the gas used. The base fee per transaction is calculated by multiplying the gas used by the base fee per gas. These base fees are aggregated daily.
- **Key fields**: `base_fee_per_gas`, `gas_used`, `block_timestamp`

### Component D: USD conversion and final aggregation

- **Purpose**: Normalize all fee components to USD and aggregate the final supply-side fees
- **Logic**: Daily aggregated fees for each product are converted to USD. For Mantra Chain, pre-migration fees are converted using the price of the legacy asset, while post-migration fees are converted using the price of the migrated asset. For Mantra Zone and Mantra EVM, fees are multiplied by the respective end-of-day asset prices. The final supply-side fees metric is calculated as the sum of these USD-denominated fees across Mantra Chain, Mantra Zone, and Mantra EVM.
- **Key fields**: `fees`, `swap_fee`, `base_fee`, `price_usd`
