OP Mainnet batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense).

OP Mainnet is an L2 smart contract platform for decentralized applications on Ethereum. OP Mainnet was founded by Jinglan Wang, Karl Floersch & Kevin Ho and launched in 2021.

Optimism team & investors own and govern the protocol. Optimism’s investors include Paradigm, a16z, IDEO CoLab Ventures, etc.

# OP Mainnet Active users (daily) Methodology

## 1. Overview

The Optimism daily active users (DAU) metric measures the number of unique addresses that initiated at least one transaction on the Optimism blockchain within a given day. This metric provides insight into user engagement and activity levels on the Optimism Layer 2 network. The calculation identifies unique transaction senders per day by analyzing all Optimism transactions and extracting distinct `from_address` values grouped by daily time boundaries.

## 2. Data sources

- **Optimism transaction records**: Raw transaction data from the Optimism blockchain including transaction metadata, sender and recipient addresses, gas usage information, and execution details
- **Block timestamp data**: Timestamp information for each transaction indicating when it was included in a block on the Optimism chain
- **Transaction gas data**: Gas usage metrics including Layer 2 gas consumption, Layer 1 gas costs, gas prices, and fee calculations specific to Optimism's rollup architecture

## 3. Step-by-step calculation

### Component A: Transaction data extraction
- **Purpose**: Extract all relevant transaction data from the Optimism blockchain
- **Logic**: Collect all transactions from Optimism including their timestamps, sender addresses (`from_address`), recipient addresses (`to_address`), and gas-related metrics. Each transaction is enhanced with static metadata including the chain identifier set to 'optimism', token address set to the Optimism WETH contract address, and token symbol set to 'ETH'. Gas fee calculations are performed for both Layer 2 execution costs and Layer 1 data availability costs.
- **Key fields**: `block_timestamp` for timing, `from_address` as the user identifier, `transaction_hash` for uniqueness, gas usage amounts and prices for fee calculations

### Component B: Daily user aggregation
- **Purpose**: Identify unique users per day from transaction activity
- **Logic**: Process the transaction data by truncating `block_timestamp` values to daily boundaries using day-level granularity. Extract distinct `from_address` values for each day, treating each unique sender address as a daily active user. Apply business categorization by setting `user_type` to 'Transaction sender' to classify the type of user activity being measured. Include standard metadata fields for market sector, business segment, and product categorization.
- **Key fields**: `timestamp` (truncated to day), `user_dau` (unique sender addresses), `user_type` classification, business metadata fields

### Final aggregation
- **Combining components**: The transaction data flows directly into the daily aggregation step where unique sender addresses are identified per day
- **Time aggregation**: Timestamps are truncated to daily boundaries, and all transactions within the same calendar day are grouped together for user deduplication
- **Incremental processing**: When running incrementally, the calculation processes only recent data based on a configurable lookback period to ensure efficient updates while maintaining data completeness
- **Final calculation**: The final DAU count represents the number of distinct `from_address` values that appear in transactions for each day on the Optimism blockchain, with additional filtering applied based on chain availability constraints
