# Robonomics Substrate Fees Methodology

## 1. Overview

Fees are measured as the total value paid by users to execute transactions and interact with Robonomics Substrate. These fees consist of base transaction costs and optional tips provided to network validators to prioritize specific extrinsics. This metric represents the total economic value generated by network usage and is denominated in USD.

## 2. Data sources

- **Blockchain events**: `TransactionFeePaid` events from Robonomics Substrate
- **External data**: End-of-day price feeds for the native Robonomics asset

## 3. Step-by-step calculation

### Component A: Transaction fee and tip extraction

- **Purpose**: Identify the individual components of transaction costs for every extrinsic on the network.
- **Logic**: `TransactionFeePaid` events are parsed from Robonomics Substrate. The base fee amount is extracted from the second element of the event data, while the tip amount is extracted from the third element. These values are summed to determine the total native fee for each transaction.
- **Key fields**: `event_data` (containing amount and tip values), `event_method`

### Component B: Normalization and USD conversion

- **Purpose**: Convert native fee amounts into a standardized USD valuation.
- **Logic**: The sum of transaction fees and tips is normalized by decimal precision. The resulting native values are multiplied by end-of-day price feeds for the native Robonomics asset to calculate the USD-equivalent value for each record.
- **Key fields**: `amount`, `tip`, `price_usd`

### Component C: Daily aggregation and zero-filling

- **Purpose**: Generate a continuous daily time series of fee data.
- **Logic**: All USD-denominated fees are aggregated by day using UTC boundaries. A zero-filling strategy is applied to the final dataset to ensure that days without recorded transaction activity are represented with a value of zero, maintaining a consistent daily granularity.
- **Key fields**: `block_timestamp`, `fees`
