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 Revenue Methodology

## 1. Overview

SpookySwap revenue represents the protocol's share of trading fees collected from decentralized exchange activity on the Fantom blockchain. SpookySwap charges a 0.2% fee on all trades and retains 15% of these fees as protocol revenue, with the remaining 85% distributed to liquidity providers. This metric answers the question: "How much revenue does SpookySwap generate from its trading fee structure?"

The calculation methodology aggregates all trading activity, calculates total fees collected, and applies the 15% protocol fee share to determine revenue.

## 2. Data sources

- **Blockchain events**: Parsed Fantom `Pair_Swap_event` logs from SpookySwap v1 pair contracts containing swap transaction details
- **Factory events**: Parsed Fantom `PairFactory_PairCreated_event` logs that define all SpookySwap trading pairs and their characteristics  
- **Transaction data**: Fantom transaction records providing user addresses and transaction context
- **External data**: End-of-day token price feeds for USD conversion of trading volumes
- **Token metadata**: Token information including symbols and decimal places for proper amount calculations

## 3. Step-by-step calculation

### Component A: Trading pair registry
- **Purpose**: Creates a master registry of all SpookySwap trading pairs and their characteristics
- **Logic**: Extracts all pair creation events from the SpookySwap factory contract on Fantom. Each event contains the pair contract address, token0 address, token1 address, and implicitly defines the 0.2% fee tier. Joins with token metadata to retrieve decimal places and symbols for both tokens in each pair. Creates human-readable pair names by concatenating token symbols.
- **Key fields**: `account_address` (pair contract), `token0_address`, `token1_address`, `fee_tier` (0.2%), `token0_decimals`, `token1_decimals`, `account_name` (token symbol pair)

### Component B: Raw trade extraction  
- **Purpose**: Extracts individual swap transactions from blockchain events
- **Logic**: Processes all `Pair_Swap_event` logs from SpookySwap pair contracts starting from April 17, 2021. Each swap event contains four amount fields representing tokens flowing in and out of the pool. Calculates net token changes by subtracting out amounts from in amounts for both tokens. Joins with Fantom transaction data to obtain user addresses. Filters out invalid or test transactions.
- **Key fields**: `block_timestamp`, `transaction_hash`, `account_address` (pair contract), `token0_amount` (net change), `token1_amount` (net change), `user_address`

### Component C: Volume aggregation and USD conversion
- **Purpose**: Aggregates individual trades to daily volumes and converts to USD values
- **Logic**: Groups all trades by day and trading pair. Joins with the trading pair registry to obtain token metadata. Corrects raw token amounts for decimal places by dividing by 10 raised to the token's decimal count. Takes absolute values of token amounts to handle bidirectional swaps. Converts both token amounts to USD using end-of-day price feeds matched by timestamp, chain, and token address. Applies manipulation protection by taking the lesser of the two USD values, ensuring inflated prices on one token cannot artificially boost volume calculations.
- **Key fields**: `timestamp` (daily), `trading_volume` (USD value), `token0_amount` (decimal-corrected), `token1_amount` (decimal-corrected), `fee_tier`

### Component D: Fee calculation
- **Purpose**: Calculates total fees collected from trading activity
- **Logic**: Aggregates daily trading volumes across all SpookySwap pairs. Multiplies each day's total trading volume by the 0.2% fee tier to determine fees collected. The calculation assumes all pairs use the same fee tier. Groups by day to produce daily fee totals.
- **Key fields**: `trading_volume` (aggregated USD), `fees` (trading_volume × 0.002)

### Final aggregation: Revenue calculation
- **Combining components**: Takes the daily fee calculations from the previous step as direct input
- **Currency conversion**: All amounts are already in USD from the volume conversion step using end-of-day price feeds
- **Time aggregation**: Data is aggregated to daily boundaries using timestamp truncation to day level
- **Final calculation**: Multiplies total daily fees by the protocol fee share of 15% (0.15) to determine SpookySwap's revenue portion. The formula is: revenue = fees × 0.15, where fees represent the total 0.2% trading fees collected, and SpookySwap retains 15% as protocol revenue while distributing 85% to liquidity providers.
