Liquidity providers (LPs) deposit funds into Aura Finance and receive a return on investment (supply-side fees).

Aura Finance is an asset management and staking protocol built on Ethereum. Aura Finance was founded by an anonymous team and launched in June 2022.

AURA tokenholders own and govern the protocol. They currently take a cut of the total yield generated (revenue).

# Aura Finance Expenses Methodology

## 1. Overview

This metric calculates AuraFinance's total expenses in the form of AURA token incentives paid to users. The expenses represent the cost of incentivizing liquidity providers and stakers through AURA token rewards, capturing both funded incentives (from existing token pools) and minted incentives (newly created AURA tokens). The calculation aggregates all AURA token distributions from protocol-controlled accounts to users across multiple chains and converts them to USD values.

## 2. Data sources

The methodology uses several types of blockchain data sources:

- **Blockchain events**: Parsed `RewardFactory_TokenRewardPoolCreated` and `RewardFactoryV2_TokenRewardPoolCreated` events from Ethereum, Arbitrum, Base, Gnosis, Optimism, and Polygon to identify incentive distribution contracts
- **Reward events**: Parsed `BaseRewardPool4626_RewardPaid` and `BaseRewardPool4626V2_RewardPaid` events from all supported chains to identify when minted incentives are distributed
- **Token transfer data**: AURA token transfer events from Ethereum, Arbitrum, Base, Gnosis, Optimism, and Polygon chains, including both token-specific and sender-specific transfer logs
- **External data**: End-of-day token price feeds for USD conversion and token metadata for decimal corrections

## 3. Step-by-step calculation

### Component A: Incentive account identification
- **Purpose**: Identifies all contract addresses that distribute AURA token incentives to users
- **Logic**: Extracts contract addresses from `RewardFactory_TokenRewardPoolCreated` events across all chains. These events are emitted when new reward pools are created. Filters to only include non-removed events. Creates a mapping of chain to incentive account addresses.
- **Key fields**: `token` field from events becomes the `account_address`, with chain information preserved

### Component B: Minted incentive transaction identification
- **Purpose**: Identifies specific transactions where newly minted AURA incentives are paid to users
- **Logic**: Parses `BaseRewardPool4626_RewardPaid` events across all chains to capture when minted incentives are distributed. Creates a list of transaction hashes and user addresses that received minted incentives, used later for filtering.
- **Key fields**: `transaction_hash` and `user` address from reward events

### Component C: Funded incentives tracking
- **Purpose**: Captures AURA token transfers from existing incentive pools to users
- **Logic**: Identifies token transfers where the sender is one of the incentive accounts identified in Component A, the token is AURA, and the recipient is not the null address. Standardizes all transfers to report as 'ethereum' chain with Ethereum AURA token address for consistency. Uses chain-specific AURA token addresses but maps them to the canonical Ethereum address.
- **Key fields**: `from_address` (incentive account), `to_address` (user), `value` (AURA amount), `token_address` (chain-specific AURA token)

### Component D: Minted incentives tracking  
- **Purpose**: Captures newly minted AURA token distributions to users
- **Logic**: Identifies AURA token transfers from L2 coordinator addresses and the null address (indicating newly minted tokens). For L2 chains, captures transfers from specific coordinator addresses. For Ethereum, captures transfers from the null address. Filters these transfers to only include transactions identified in Component B to ensure they represent actual minted incentive distributions. Standardizes reporting to 'ethereum' chain.
- **Key fields**: `from_address` (L2 coordinator or null address), `to_address` (user), `value` (AURA amount), filtered by `transaction_hash` match

### Component E: Daily aggregation and classification
- **Purpose**: Combines funded and minted incentives into daily totals
- **Logic**: Unions the funded and minted incentives, truncates timestamps to daily boundaries, and classifies each incentive type. Assigns business classification as 'Asset management' and 'yield_aggregator'. Preserves both the real chain where the transfer occurred and maps to 'ethereum' for reporting consistency.
- **Key fields**: `timestamp` (daily), `token_incentives` (AURA amount), `account_name` (funded_incentives or minted_incentives)

### Component F: USD conversion and decimal correction
- **Purpose**: Converts AURA token amounts to USD values with proper decimal handling
- **Logic**: Applies the `convert_to_usd_and_correct_decimals` macro to convert AURA amounts to USD using end-of-day price feeds. Corrects for AURA token decimals to ensure proper token amount representation. This handles both price conversion and decimal standardization in one step.
- **Key fields**: `token_incentives` becomes USD-denominated value

### Final aggregation
- **Combining components**: Sums all USD-converted AURA incentives by timestamp, chain, and business classification. Maps the real chain back to `chain_id` for final reporting
- **Currency conversion**: Uses end-of-day AURA token prices for USD conversion, applied through the standardized conversion macro
- **Time aggregation**: Daily boundaries using timestamp truncation to day level
- **Final calculation**: The final expenses value represents the total USD value of AURA token incentives distributed by AuraFinance to users each day. This includes both funded incentives from existing pools and newly minted AURA tokens. The `finalize_metric_expenses` macro ensures data quality with forward-fill logic for missing days and proper schema validation.
