# Mantra Chain Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of transaction fees and tips distributed to validators for securing and processing transactions on Mantra Chain. This metric is utilized to assess the economic incentives provided to network validators and the overall security budget of the blockchain. On Mantra Chain, all transaction fees and tips are allocated directly to validators as supply-side revenue. Consequently, supply-side fees are calculated as equivalent to the total transaction fees collected on the network.

## 2. Data sources

- **Blockchain events**: Transaction fees and transaction tips are extracted from transaction records on Mantra Chain, covering Mantra Chain
- **External data**: End-of-day price feeds are utilized for the native assets (`OM` and `MANTRA`)

## 3. Step-by-step calculation

### Component A: Transaction fee and tip extraction

- **Purpose**: The extraction of raw transaction fees and tips from Mantra Chain transactions.
- **Logic**: Transaction fees and tips are extracted from transaction records. Prior to the Mantra Chain V7.0.0 upgrade (before block 13,000,000), fees are denominated in `uom` and normalized by decimal precision using 6 decimals. Following the V7.0.0 upgrade (at or after block 13,000,000), fees are denominated in `amantra` and normalized by decimal precision using 18 decimals. The total transaction fee for each transaction is calculated by summing the normalized transaction fee and transaction tip.
- **Key fields**: `transaction_fee`, `transaction_tip`, `block_height`, `block_timestamp`

### Component B: Asset denomination and daily aggregation

- **Purpose**: The daily aggregation of fees and the assignment of the correct asset identifier based on the network version.
- **Logic**: Normalized transaction fees are aggregated daily by truncating transaction timestamps to UTC day boundaries. For transactions occurring before block 13,000,000, fees are denominated in `OM` (using the `mantra-dao` asset identifier). For transactions occurring at or after block 13,000,000, fees are denominated in `MANTRA` (using the `mantra` asset identifier).
- **Key fields**: `block_timestamp`, `block_height`, `transaction_fee`

### Component C: USD conversion and final aggregation

- **Purpose**: The conversion of daily aggregated fees into USD.
- **Logic**: Daily aggregated fees for each asset are multiplied by their respective end-of-day asset prices. The resulting USD values are aggregated to produce the final daily supply-side fees for Mantra Chain.
- **Key fields**: `fees`, `price_usd`
