# Trojan Supply-side fees Methodology

## 1. Overview

Supply-side fees represent the portion of total fees that are distributed to liquidity providers, stakers, or other participants who supply assets or services to a protocol. For Trojan, this metric is explicitly set to zero, indicating that the protocol retains all collected fees rather than sharing revenue with supply-side participants. The calculation infrastructure processes actual fee collection data but applies a business rule that categorizes all fees as protocol revenue rather than supply-side compensation.

## 2. Data sources

The calculation uses the following raw data sources:
- **Solana native transfers**: Native SOL transfer events on the Solana blockchain, specifically transfers directed to Trojan's designated fee collection addresses
- **End-of-day price feeds**: Token price data used to convert SOL amounts to USD values for standardized reporting

## 3. Step-by-step calculation

### Component A: Fee collection data extraction
- **Purpose**: Identifies and extracts actual fee payments made to Trojan protocol
- **Logic**: Filters Solana native transfer events to capture transfers sent to Trojan's specific fee collection address (`9yMwSPk9mrXSN7yDHUuZurAh1sjbJsfpUqjZ7SvVtdco`). Each transfer includes the transaction timestamp, sender address, and transfer amount in lamports (the smallest unit of SOL). The system captures the transaction signer as the fee payer and records the native SOL token address for all transfers.
- **Key fields**: `block_timestamp` for timing, `transaction_signer` for the fee payer, `amount` for the fee amount in lamports, and `token_address` set to SOL's native token identifier

### Component B: Daily fee aggregation and USD conversion  
- **Purpose**: Aggregates collected fees by day and converts to USD for standardized reporting
- **Logic**: Groups the filtered transfer data by day using timestamp truncation, summing all fee amounts within each day. Converts lamport amounts to SOL by dividing by 1e9 (since 1 SOL = 1,000,000,000 lamports). Applies end-of-day price feeds to convert SOL amounts to USD values using the standard Token Terminal currency conversion methodology. Groups by timestamp, chain identifier, and product identifier to create daily fee totals.
- **Key fields**: `timestamp` truncated to day boundaries, `fees` as the daily SOL amount, converted to USD values through price feed application

### Final calculation: Supply-side fee allocation
- **Business rule application**: Trojan's fee structure designates all collected fees as protocol revenue rather than supply-side compensation. The calculation explicitly sets the `fees_supply_side` field to zero for all time periods and fee collection events.
- **Final calculation**: Supply-side fees = 0 (regardless of total fees collected). This represents a business rule that Trojan does not share fee revenue with liquidity providers, stakers, or other supply-side participants. All fees are retained by the protocol as revenue.

The methodology ensures complete fee tracking infrastructure while applying Trojan's specific business model where supply-side participants do not receive fee sharing.
