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

Mummy Finance is a non-custodial exchange for spot and perpetual contracts built on Fantom, Optimism, and Arbitrum. Mummy Finance was founded by an anonymous team and was launched in December 2022.

MMY tokenholders own and govern the protocol. They currently take a cut of the total trading fees paid by traders (revenue).

# Mummy Finance Expenses Methodology

## 1. Overview

Mummy expenses represents the total USD value of escrowed MMY tokens distributed as incentives to users of the Mummy protocol. This metric captures operational expenses related to token-based rewards across the protocol's staking mechanisms. Escrowed MMY (esMMY) tokens are non-transferable rewards that must be vested for one year before becoming liquid MMY tokens. The calculation aggregates daily claim events from staking tracker contracts across Arbitrum, Fantom, and Optimism networks.

## 2. Data sources

- **Blockchain events**: Parsed `StakedMmyTracker_Claim_event` and `StakedMlpTracker_Claim_event` logs from Arbitrum, Fantom, and Optimism networks capturing escrowed token claims
- **Token metadata**: MMY token information including symbols, addresses, and decimal specifications across supported chains  
- **External data**: End-of-day MMY token price feeds from Fantom network (used for all chains due to superior price data availability)

## 3. Step-by-step calculation

### Component A: Escrowed token incentives extraction
- **Purpose**: Extract and standardize escrowed MMY token claim events from staking tracker contracts
- **Logic**: Query parsed blockchain event logs for `StakedMmyTracker_Claim_event` and `StakedMlpTracker_Claim_event` across three chains (Arbitrum, Fantom, Optimism). Extract the `amount` field from each claim event along with transaction metadata. Map all events to use Fantom as the pricing chain while preserving the original chain information in a separate field. Categorize all events as 'Escrowed token incentives' within the derivatives market sector and perpetual business segment.
- **Key fields**: `block_timestamp` for timing, `transaction_hash` and `log_index` for event identification, `address` for user account, `amount` for claimed token quantity, hardcoded MMY token addresses for each supported chain

### Component B: Token metadata enrichment  
- **Purpose**: Add token symbol and contract details to the raw claim events
- **Logic**: Join the extracted claim events with token metadata using chain and token address as join keys. This adds symbol information and other token-specific details needed for proper identification and display.
- **Key fields**: `symbol` for token identification, token contract addresses, chain specifications

### Component C: USD conversion and decimal correction
- **Purpose**: Convert raw token amounts to standardized USD values with proper decimal handling
- **Logic**: Apply currency conversion using end-of-day MMY price feeds from Fantom network. Correct for token decimal places to ensure amounts are in standard units. This step uses Fantom pricing data for all chains due to better MMY token price availability on that network.
- **Key fields**: `token_incentives` as the USD-converted amount, price feed data, decimal correction factors

### Component D: Chain mapping adjustment
- **Purpose**: Restore original chain identifications for proper attribution
- **Logic**: Replace the Fantom chain identifier (used for pricing) with the original chain where each event actually occurred. This ensures expenses are attributed to the correct blockchain network while maintaining accurate USD valuations.
- **Key fields**: `real_chain` mapped back to `chain_id` for final attribution

### Final aggregation
- **Combining components**: Sum all USD-converted escrowed token incentive amounts by day and chain
- **Currency conversion**: All amounts converted to USD using end-of-day MMY token prices from Fantom network
- **Time aggregation**: Daily boundaries determined by truncating blockchain timestamps to day precision  
- **Final calculation**: The expenses metric equals the total daily USD value of claimed escrowed MMY tokens, with zero-fill strategy applied for days with no activity to maintain continuous time series
