# Energy Web X Supply-side fees Methodology

## 1. Overview

Supply-side fees represent the portion of transaction fees that are distributed to network participants who provide infrastructure services (validators, stakers, miners, etc.). For Energy Web Chain, this metric is consistently zero because the protocol does not distribute transaction fees to supply-side participants. All transaction fees are either burned or handled through other mechanisms not classified as supply-side revenue sharing.

## 2. Data sources

The calculation relies on these underlying data sources:
- **Energy Web Chain blockchain events**: Raw blockchain event logs from the Energy Web Chain, specifically focusing on transaction payment events
- **Transaction payment events**: Parsed `TransactionFeePaid` events from the `transactionPayment` pallet that contain fee and tip amounts
- **External price data**: End-of-day price feeds from CoinGecko for Energy Web Token (EWT) to enable USD conversion
- **Token metadata**: Energy Web Token specifications including decimal precision (18 decimals)

## 3. Step-by-step calculation

### Component A: Event data extraction
- **Purpose**: Extract and parse transaction fee payment events from Energy Web Chain
- **Logic**: Filter Energy Web Chain blockchain events to identify `TransactionFeePaid` events from the `transactionPayment` pallet. These events contain structured data about fees paid for each transaction, including both the base transaction fee and any additional tips paid by users.
- **Key fields**: Extract `transaction_fee` and `transaction_tip` values from the event data array, along with `extrinsic_id` for transaction identification and `timestamp` for daily aggregation

### Component B: Fee calculation and conversion
- **Purpose**: Process raw fee amounts and convert to standard units
- **Logic**: Combine the `transaction_fee` and `transaction_tip` amounts to get the total fee paid per transaction. Convert from the native wei denomination to EWT by dividing by 10^18. Group transactions by day for daily aggregation.
- **Key fields**: Calculate total `transaction_fee` as the sum of base fee and tip, apply decimal conversion to get EWT amounts, and maintain daily `timestamp` grouping

### Component C: USD conversion
- **Purpose**: Convert EWT fee amounts to USD values
- **Logic**: Apply USD conversion using end-of-day CoinGecko price feeds for Energy Web Token. This converts the EWT-denominated fees to USD equivalents for standardized reporting.
- **Key fields**: Convert `fees` amounts using CoinGecko exchange rates for the `energy-web-token` price feed

### Final aggregation
- **Combining components**: The total fees calculation provides the foundation, but supply-side fees are explicitly set to zero for all records
- **Currency conversion**: USD conversion is applied to total fees for reference, but supply-side fees remain zero regardless of price fluctuations
- **Time aggregation**: Daily boundaries are maintained throughout the calculation process
- **Final calculation**: Supply-side fees are hardcoded to 0 for all time periods, reflecting that Energy Web Chain does not distribute transaction fees to validators, stakers, or other supply-side infrastructure providers. The protocol design does not include fee sharing mechanisms with network participants.
