Validators process transactions and receive fees from users (supply-side fees).

Gnosis Chain is a smart contract platform for decentralized applications (a blockchain). Gnosis was founded by Martin Köppelmann and Stefan George and launched in 2015.

GNO holders own and govern the protocol. They currently take a cut of the total transaction fees paid by users (revenue).

# Gnosis Fees Methodology

## 1. Overview

The Gnosis fees metric measures the total daily transaction fees paid by users on the Gnosis blockchain, expressed in USD. This metric captures the economic cost of using the Gnosis network by tracking both regular gas fees and blob gas fees from all transaction executions. The calculation aggregates fee amounts daily and converts them to USD using WXDAI token pricing, providing insight into the total fee revenue generated by the Gnosis network.

## 2. Data sources

- **Gnosis blockchain transaction records**: Complete transaction data including gas usage metrics, effective gas prices, blob gas usage, and execution timestamps
- **End-of-day token price feeds**: USD pricing data for WXDAI token (contract address `0xe91d153e0b41518a2ce8dd3d7944fa863463a97d`) used for currency conversion
- **Token metadata**: Decimal precision and formatting information for WXDAI token to ensure accurate price calculations

## 3. Step-by-step calculation

### Component A: Transaction data extraction
- **Purpose**: Extract and normalize all Gnosis blockchain transaction data with associated gas fee information
- **Logic**: Pull all transaction records from Gnosis blockchain data, including transaction identifiers, block information, addresses, and gas metrics. Extract `gas_used`, `blob_gas_used`, `receipt_effective_gas_price`, and `receipt_blob_gas_price` fields. Convert gas prices from wei denomination to WXDAI units by dividing by 10^18. Apply data type conversions to ensure numeric precision for large gas values.
- **Key fields**: `block_timestamp` for timing, `gas_used` and `effective_gas_price` for regular fees, `blob_gas_used` and `blob_gas_price` for blob fees, `transaction_hash` for uniqueness

### Component B: Daily fee aggregation
- **Purpose**: Calculate total daily fees paid on Gnosis by combining regular gas fees and blob gas fees
- **Logic**: Group transactions by day using timestamp truncation. Calculate two separate fee components: regular gas fees by multiplying `gas_used` by `effective_gas_price`, and blob gas fees by multiplying `blob_gas_used` by `blob_gas_price`. Sum each fee component separately by day, then union the results to create a complete daily fee dataset. This approach ensures both traditional transaction fees and newer blob gas fees are captured.
- **Key fields**: `timestamp` truncated to day boundaries, `fee_amount` as the calculated daily fee total

### Final aggregation
- **Combining components**: Union regular gas fees and blob gas fees into a single daily fee amount, summing all fee components for each day
- **Currency conversion**: Convert WXDAI-denominated fees to USD using end-of-day WXDAI price feeds through the standard USD conversion process
- **Time aggregation**: Daily boundaries defined by timestamp truncation, with incremental processing for recent data updates
- **Final calculation**: Total daily fees in USD = sum of (regular gas fees + blob gas fees) converted from WXDAI to USD using daily exchange rates, with zero-filling applied for days with no transaction activity
