# Hyperbridge App Supply-side fees Methodology

## 1. Overview

Supply-side fees measures the share of total fees generated by Hyperbridge App that is distributed to infrastructure service providers, primarily relayers. These fees compensate providers for the costs associated with cross-chain message delivery and verification. The metric is calculated by determining the total fees paid by users and subtracting the portion of fees retained by the protocol treasury.

## 2. Data sources

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

## 3. Step-by-step calculation

### Component A: Hyperbridge App fee extraction

- **Purpose**: To capture the total fees paid by users for cross-chain messaging and relayer services.
- **Logic**: Relayer fees are parsed from `AccumulateFees` events within the `relayer` pallet. Messaging fees are parsed from `FeePaid` events within the `messagingFees` pallet. Only successful transactions are included. Fee amounts, which are primarily denominated in DAI for predictable tracking, are normalized by decimal precision.
- **Key fields**: `event_data`, `event_pallet`, `event_method`

### Component B: Protocol revenue calculation

- **Purpose**: To identify the portion of fees directed to the protocol treasury, which must be excluded from supply-side fees.
- **Logic**: Native asset transfers are parsed from `Transfer` events in the `balances` pallet. Transactions where the recipient address matches the official treasury address (`13UVJyLkyUpEiXBx5p776dHQoBuuk3Y5PYp5Aa89rYWePWA3`) are aggregated as revenue. Transfers originating from identified founder addresses are excluded to ensure data accuracy.
- **Key fields**: `from_address`, `to_address`, `amount`

### Component C: Supply-side fee aggregation and USD conversion

- **Purpose**: To calculate the final supply-side fees and normalize the values to USD.
- **Logic**: Supply-side fees are calculated by subtracting protocol revenue from the total fees collected. All amounts are normalized by decimal precision and converted to USD using end-of-day price feeds. Values are aggregated to daily granularity using UTC day boundaries, and a zero-filling strategy is applied to ensure continuity in the time series.
- **Key fields**: `fees`, `revenue`, `block_timestamp`
