Liquidity providers deposit funds into SpookySwap and receive trading fees from traders (supply-side fees).

SpookySwap is a non-custodial exchange protocol built on Fantom. SpookySwap was launched in April 2021.

BOO tokenholders own and govern the protocol. They currently take a cut of the total interest paid by borrowers (revenue).

# SpookySwap Supply-side fees Methodology

## 1. Overview

SpookySwap supply-side fees represent the portion of trading fees that goes to liquidity providers (LPs) on the SpookySwap V1 decentralized exchange on Fantom. This metric answers how much fee revenue liquidity providers earn from their capital provision. The calculation takes total protocol trading fees and allocates 85% to LPs, with the remaining 15% going to the protocol. This fee split is hardcoded based on SpookySwap's tokenomics structure.

## 2. Data sources

- **Blockchain events**: Parsed Fantom `Swap` events from SpookySwap V1 trading pairs containing token amounts and trade details
- **Factory events**: Fantom `PairCreated` events from the SpookySwap V1 PairFactory contract establishing trading pairs and fee structures
- **Transaction data**: Fantom transaction records for user address identification and timestamp verification
- **External data**: End-of-day token price feeds for USD conversion and token metadata including decimals and symbols
- **Data types**: Daily aggregated trading volumes, fee tier configurations (0.2%), and LP fee allocation parameters (85%)

## 3. Step-by-step calculation

### Component A: Raw trade extraction
- **Purpose**: Extract individual trades from blockchain events and calculate net token changes
- **Logic**: Process parsed `Swap` events from SpookySwap V1 pairs on Fantom blockchain. For each swap event, calculate the net change in both tokens by subtracting output amounts from input amounts (`amount0In - amount0Out` and `amount1In - amount1Out`). Join with transaction records to identify user addresses and filter trades from April 17, 2021 onwards when SpookySwap launched
- **Key fields**: `transaction_hash`, `log_index`, `account_address` (trading pair), `token0_amount`, `token1_amount`, `block_timestamp`

### Component B: Trading pair metadata
- **Purpose**: Establish trading pair configurations and fee structures
- **Logic**: Extract `PairCreated` events from the SpookySwap V1 PairFactory contract to identify all valid trading pairs. Each pair has a fixed fee tier of 0.2% for all trades. Join with token metadata to get decimal places and symbols for both tokens in each pair, creating human-readable pair names
- **Key fields**: `account_address` (pair contract), `token0_address`, `token1_address`, `fee_tier` (0.002), `token0_decimals`, `token1_decimals`, `account_name`

### Component C: Volume calculation and USD conversion
- **Purpose**: Convert raw token amounts to standardized USD trading volumes
- **Logic**: Aggregate trades daily and correct token amounts for decimal places by dividing by 10 raised to the token's decimal count. Convert corrected amounts to USD values using end-of-day price feeds. To prevent price manipulation, take the lesser USD value between token0 and token1 for each trade. Sum these minimum USD values across all trades in each pair for each day
- **Key fields**: `timestamp`, `trading_volume` (USD), `fee_tier`, aggregated by day and trading pair

### Component D: Total fee calculation
- **Purpose**: Calculate total protocol fees generated from trading activity
- **Logic**: Multiply daily trading volumes by the fee tier (0.2%) for each trading pair. Sum fees across all pairs to get total daily protocol fee revenue. This represents the complete fee pool before allocation between LPs and protocol
- **Key fields**: `fees` (total protocol fees in USD), aggregated daily across all pairs

### Final aggregation
- **Combining components**: Take total protocol fees and multiply by the LP fee tier of 85% (0.85) to determine supply-side fees
- **Currency conversion**: All amounts already converted to USD using end-of-day price feeds during volume calculation
- **Time aggregation**: Data aggregated to daily boundaries using timestamp truncation to day level
- **Final calculation**: Supply-side fees = Total protocol fees × 0.85, representing the portion of trading fees earned by liquidity providers for providing capital to SpookySwap pools
