# Hyperbridge Substrate Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute transactions and cross-chain messages on Hyperbridge Substrate. This includes network transaction fees paid to validators and messaging fees paid to relayers for cross-chain communication. These fees represent the total economic value generated by the network and the cost of utilizing its secure interoperability infrastructure.

## 2. Data sources

- **Blockchain events**: `TransactionFeePaid` events, `AccumulateFees` events from `relayer` pallets, and `FeePaid` events from `messagingFees` pallets on Hyperbridge Substrate
- **External data**: End-of-day price feeds for native assets

## 3. Step-by-step calculation

### Component A: Network transaction fees

- **Purpose**: Captures the base cost of executing transactions and incentivizing network security.
- **Logic**: `TransactionFeePaid` events are parsed to extract the transaction fee and the tip provided by the user. Both values are summed to determine the total cost per transaction.
- **Key fields**: `amount` representing the base fee and `tip` representing the additional priority payment.

### Component B: Relayer and messaging fees

- **Purpose**: Captures the cost of cross-chain message delivery and relayer compensation.
- **Logic**: `AccumulateFees` events are parsed from `relayer` pallets to capture fees paid in DAI for relayer services. Additionally, `FeePaid` events are extracted from `messagingFees` pallets to capture all associated cross-chain communication costs.
- **Key fields**: `event_data` containing the fee amounts paid to relayers and messaging protocols.

### Component C: Normalization and USD conversion

- **Purpose**: Standardizes all collected fees into a common currency for reporting.
- **Logic**: Native transaction fees are normalized by decimal precision and multiplied by end-of-day price feeds for the native network asset. Fees collected in DAI are normalized by decimal precision and treated as equal to USD value. All fee components are aggregated by day using UTC boundaries.
