# XAI Supply-side fees Methodology

## 1. Overview

XAI supply-side fees represent the portion of transaction fees that would be distributed to supply-side participants (such as validators or stakers) in the XAI ecosystem. However, XAI's current fee structure does not include supply-side fee distribution, so this metric is consistently set to zero. The calculation follows XAI's transaction fee processing pipeline but assigns zero to the supply-side component.

## 2. Data sources

- **XAI blockchain transactions**: Raw transaction records from the XAI Layer 3 blockchain containing transaction hashes, sender/receiver addresses, gas usage amounts, and effective gas prices
- **External price feeds**: End-of-day XAI token price feeds from CoinGecko API using the `xai-blockchain` identifier for USD conversion

## 3. Step-by-step calculation

### Component A: Transaction fee extraction
- **Purpose**: Extract and calculate individual transaction gas fees from XAI blockchain data
- **Logic**: Process raw XAI transaction records to identify gas consumption and pricing. Calculate transaction fees by multiplying `gas_used_amount` by `receipt_effective_gas_price`, then divide by 1e18 to convert from wei units to XAI token amounts. Extract transaction metadata including timestamps, transaction hashes, and participant addresses. Classify all fees under the `blockchains_l3` market sector and `blockchain` business segment.
- **Key fields**: `block_timestamp`, `transaction_hash`, `gas_used_amount`, `gas_price`, and calculated `l3_gas_fee_amount`

### Component B: Daily fee aggregation
- **Purpose**: Aggregate individual transaction fees to daily totals
- **Logic**: Group transaction-level fee data by calendar day using timestamp truncation to day boundaries. Sum all `l3_gas_fee_amount` values within each day to create daily fee totals. Maintain dimensional attributes including chain identifier, market sector, and business segment classifications. Handle incremental processing with daily partitioning for efficiency.
- **Key fields**: Aggregated `fees` amounts grouped by `timestamp` (daily), `chain_id`, `market_sector_id`, `business_segment_id`

### Component C: USD conversion
- **Purpose**: Convert native XAI token fees to USD values
- **Logic**: Join daily aggregated XAI token fees with corresponding end-of-day XAI token prices from CoinGecko. Match fees and prices by timestamp to ensure accurate daily conversion rates. Multiply native token fee amounts by the USD price for each day to calculate USD-denominated fee values.
- **Key fields**: USD-converted `fees` calculated as native token fees multiplied by daily `price`

### Final aggregation
- **Combining components**: The supply-side fees metric takes the USD-converted total fees from Component C and sets the supply-side portion to zero
- **Supply-side assignment**: All fee values are assigned zero for the supply-side component since XAI does not currently distribute fees to supply-side participants like validators or stakers
- **Data validation**: Apply schema validation and gap-filling using the `finalize_metric_fees_supply_side` macro with a `fill_zeros` strategy
- **Time boundaries**: Filter data to include only transactions up to August 22, 2025, and apply chain availability filtering
- **Final calculation**: The result is zero for all time periods, representing the absence of supply-side fee distribution in XAI's current economic model
