# XAI Revenue Methodology

## 1. Overview

The Xai revenue metric measures the total USD value of gas fees collected by the Xai Layer 3 blockchain network. This metric represents the primary revenue stream for the Xai network, which operates as an Ethereum Layer 3 solution. Revenue is calculated by aggregating all transaction gas fees paid in XAI tokens and converting them to USD using end-of-day price feeds.

## 2. Data sources

The calculation relies on two primary data sources:
- **Xai blockchain transaction data**: Raw transaction records from the Xai Layer 3 network, including transaction receipts with gas usage amounts, effective gas prices, sender and recipient addresses, and block timestamps
- **End-of-day price feeds**: Daily XAI token price data from CoinGecko (coingecko-id: 'xai-blockchain') providing USD conversion rates

## 3. Step-by-step calculation

### Component A: Transaction data extraction
- **Purpose**: Extract and standardize all Xai blockchain transactions with gas fee information
- **Logic**: Retrieve all transactions from the Xai blockchain including block timestamps, transaction hashes, sender and recipient addresses, effective gas prices (`receipt_effective_gas_price`), and gas usage amounts (`receipt_gas_used`). Each transaction is tagged with the XAI token address (`0x82af49447d8a07e3bd95bd0d56f35241523fbab1`), token symbol, and chain identifier. The data is classified under the 'blockchains_l3' market sector and 'blockchain' business segment
- **Key fields**: `block_timestamp`, `transaction_hash`, `gas_price`, `gas_used_amount`, `token_address`, and chain identification fields

### Component B: Gas fee calculation  
- **Purpose**: Calculate the actual XAI token amount paid as gas fees for each transaction
- **Logic**: For each transaction, multiply the `gas_used_amount` by the `gas_price` to get the total gas cost in wei units, then divide by 1e18 to convert to standard XAI token units. This produces the `l3_gas_fee_amount` field representing the gas fee paid in XAI tokens for each transaction
- **Key fields**: `l3_gas_fee_amount` calculated as `(gas_used_amount * gas_price) / 1e18`

### Component C: Daily fee aggregation
- **Purpose**: Aggregate all gas fees by day to create daily fee totals
- **Logic**: Group all transactions by day using timestamp truncation to day boundaries. Sum all `l3_gas_fee_amount` values for each day, maintaining the chain identifier, market sector, business segment, and token address groupings. This creates daily totals of gas fees collected in XAI tokens
- **Key fields**: Daily aggregated `fees` amounts with `timestamp` truncated to day, `timestamp_grain` set to 'day'

### Component D: USD conversion
- **Purpose**: Convert XAI-denominated fees to USD values using market prices
- **Logic**: Inner join the daily fee amounts with end-of-day XAI price data from CoinGecko on matching timestamps. Multiply each day's fee amount by the corresponding XAI price to get USD-denominated fees. The inner join ensures only days with both fee data and price data are included
- **Key fields**: `fees` converted to USD by multiplying XAI amounts by `price` from price feeds

### Final aggregation
- **Combining components**: The USD-denominated daily fees are processed through the `finalize_metric_fees` macro which standardizes the schema, validates identifiers, and fills any data gaps using a 'fill_zeros' strategy
- **Currency conversion**: Fees are converted from XAI tokens to USD using end-of-day CoinGecko price feeds matched by timestamp
- **Time aggregation**: Daily boundaries are established using timestamp truncation to day level, with all transaction fees within each day summed together
- **Final calculation**: Revenue is calculated by directly mapping fees to revenue (1:1 relationship), applying the `finalize_metric_revenue` macro for final schema standardization and gap filling. The result represents the total daily USD revenue generated by gas fees on the Xai Layer 3 network
