DeFi Saver aggregates multiple DeFi protocols and users perform different strategies through DeFi Saver.

DeFi Saver is a non-custodial DeFi aggregator built on Ethereum. DeFi Saver was founded by Nenad Palinkasevic & Andrej Cvoro and launched in 2019.

DeFi Saver team & investors own and govern the protocol. They currently take all of the total trading fees paid by traders (revenue).

# DeFi Saver Earnings Methodology

## 1. Overview

DeFiSaver earnings represents the protocol's net profit calculated as total revenue minus total expenses. The metric measures DeFiSaver's financial performance from their asset management services, specifically their yield aggregation business. Since DeFiSaver currently operates without token incentive programs, their expenses are zero, making earnings equivalent to their fee revenue. The calculation aggregates fee collection across Ethereum, Arbitrum, and Optimism chains on a daily basis.

## 2. Data sources

The calculation relies on the following raw data sources:
- **Token transfer events**: Parsed `Transfer` events from Ethereum, Arbitrum, and Optimism blockchains, specifically capturing transfers to DeFiSaver's fee receiver contract addresses
- **Transaction data**: Blockchain transaction logs to validate transfer events and filter out removed or invalid transactions
- **Token metadata**: Token contract information including decimal places and symbol data for accurate amount calculations
- **End-of-day price feeds**: Token price data for USD conversion of fee amounts

## 3. Step-by-step calculation

### Component A: Fee collection identification
- **Purpose**: Identifies all tokens received by DeFiSaver as protocol fees
- **Logic**: The system monitors specific fee receiver contract addresses across three blockchains. On Ethereum, fees are collected at `0x6467e807db1e71b9ef04e0e3afb962e4b0900b2b`. On Arbitrum and Optimism, fees are collected at `0x76720ac2574631530ec8163e4085d6f98513fb27`. All token transfer events where these addresses are the recipient are captured from blockchain event logs. The system filters out any removed or invalid transactions to ensure data quality.
- **Key fields**: `to_address` for fee receiver identification, `token_address` for token type, `value` for raw transfer amount, `block_timestamp` for timing, `transaction_hash` and `log_index` for uniqueness

### Component B: Revenue calculation and standardization
- **Purpose**: Converts raw token transfers into standardized daily USD revenue figures
- **Logic**: Raw token transfer amounts are first corrected using token-specific decimal places to convert from blockchain integers to actual token amounts. These corrected amounts are then converted to USD using end-of-day price feeds matched by date and token. The system aggregates all fee collections by day, summing across all tokens and chains. Any missing days in the time series are filled with zero values to ensure complete coverage. All revenue is classified under the Asset Management business line with yield_aggregator business segment.
- **Key fields**: `amount` for corrected token quantities, `revenue` for USD-converted daily totals, `timestamp` for daily aggregation boundaries, `chain` for blockchain identification

### Component C: Expenses determination
- **Purpose**: Calculates total protocol expenses, primarily from token incentive programs
- **Logic**: The system evaluates token incentive expenses by referencing the protocol's incentive programs. Currently, DeFiSaver operates without active token incentive programs, so all token incentive values are set to zero. The expenses model takes the same time structure as revenue (daily aggregation across the same chains and time periods) but populates all expense amounts with zero values.
- **Key fields**: `token_incentives` set to zero, `expenses` totaling zero for all time periods

### Final aggregation
- **Combining components**: Revenue and expenses are combined using a subtraction operation where earnings equals revenue minus expenses. Since expenses are currently zero, earnings equals revenue in the current implementation.
- **Currency conversion**: All amounts are converted to USD using end-of-day price feeds, ensuring consistent currency representation across different tokens and chains
- **Time aggregation**: Data is aggregated to daily boundaries using timestamp truncation, with all transfers occurring within a calendar day summed together
- **Final calculation**: The final earnings metric is calculated as the daily USD sum of all fee collections across Ethereum, Arbitrum, and Optimism, minus any token incentive expenses (currently zero), resulting in net daily earnings for DeFiSaver's asset management operations
