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 Expenses Methodology

## 1. Overview

SpookySwap expenses represent the total value of liquidity incentives distributed by the protocol to liquidity providers. The metric captures the cost incurred by SpookySwap in rewarding users who provide liquidity to its decentralized exchange pools. The calculation aggregates daily BOO token distributions from SpookySwap's incentive contracts and converts them to USD values.

## 2. Data sources

- **Fantom blockchain event logs**: Parsed `FarmV2_Harvest` events that capture BOO token rewards claimed by liquidity providers
- **Fantom blockchain event logs**: Parsed `SpookyToken_Transfer` events specifically from MasterChef contracts distributing BOO tokens
- **End-of-day price feeds**: Token price data for converting BOO token amounts to USD values
- **Token metadata**: BOO token contract information including decimal precision for accurate amount calculations

## 3. Step-by-step calculation

### Component A: Liquidity incentive event extraction
- **Purpose**: Captures all BOO token distributions from SpookySwap's incentive programs
- **Logic**: Extracts events from two sources on Fantom chain. First, collects `FarmV2_Harvest` events where users claim BOO token rewards, capturing the harvest amounts. Second, identifies `SpookyToken_Transfer` events where BOO tokens are transferred from specific MasterChef contract addresses, filtering transfers to only include those originating from the MasterChef contract and involving the BOO token address. Both event types are standardized with transaction metadata, chain identification, business line classification as Exchange AMM, and version labeling.
- **Key fields**: `block_timestamp` for timing, `transaction_hash` and `log_index` for event identification, `account_address` for recipient identification, `token_address` for BOO token filtering, `amount` for incentive quantity

### Component B: Account dimension mapping
- **Purpose**: Provides human-readable labels for incentive distribution contracts
- **Logic**: Maintains a hardcoded mapping of contract addresses to descriptive names. Maps the primary MasterChef contract and MasterChef V2 contract addresses to their respective labels for easier identification and reporting.
- **Key fields**: `account_address` for contract identification, `account_name` for descriptive labeling, `chain` for Fantom network specification

### Component C: Daily aggregation and USD conversion
- **Purpose**: Combines incentive events with contract information and converts to daily USD values
- **Logic**: Joins the liquidity incentive events with the account dimension table using contract addresses to attach descriptive names. Truncates event timestamps to daily boundaries and assigns daily grain labeling. Converts BOO token amounts to USD values using end-of-day price feeds and applies decimal correction based on BOO token metadata to ensure accurate amount calculations.
- **Key fields**: `timestamp` for daily boundaries, `chain_id` for network identification, `token_incentives` for USD-converted amounts, `contract_name` and `account_name` for contract identification

### Final aggregation
- **Combining components**: The liquidity incentive facts are inner joined with account dimensions to ensure only valid incentive contracts are included
- **Currency conversion**: BOO token amounts are converted to USD using end-of-day price feeds with decimal precision correction applied
- **Time aggregation**: Events are aggregated to daily boundaries using timestamp truncation
- **Final calculation**: Token incentives are directly relabeled as expenses, representing the total daily USD value of BOO tokens distributed as liquidity rewards. Missing days are filled with zeros to maintain continuous time series data.
