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

Base is an Ethereum Layer 2 (L2) offering a secure, low-cost, builder-friendly way for anyone, anywhere, to build onchain.

Coinbase team owns and governs the protocol. Coinbase is a public company and its investors include Andreessen Horowitz, Vanguard Group, ARK Investment Management, etc.

# Base Active users (daily) Methodology

## 1. Overview

Daily Active Users (DAU) measures the number of unique addresses that initiated at least one transaction on the Base blockchain within a 24-hour period. This metric provides insight into the level of user engagement and activity on the Base Layer 2 network. The calculation identifies unique transaction senders per day, treating each unique address that sends a transaction as an active user for that day.

## 2. Data sources

The calculation relies on the following raw data sources:
- **Base blockchain transactions**: Complete transaction records from the Base Layer 2 network, including transaction metadata and sender information
- **Transaction timestamps**: Block timestamps indicating when each transaction was confirmed on the Base blockchain
- **Address data**: Transaction sender addresses (`from_address`) that represent the users initiating transactions

## 3. Step-by-step calculation

### Component A: User identification and classification
- **Purpose**: Extract and classify user addresses from Base blockchain transactions
- **Logic**: The system processes all Base blockchain transaction records and extracts the sender address (`from_address`) from each transaction. Each sender address is classified as a 'Transaction sender' user type, representing an active user who initiated blockchain activity. The system assigns metadata including chain identifier ('base'), market sector ('blockchains_l2'), and business segment ('blockchain') to categorize the activity appropriately.
- **Key fields**: `user_address` (the transaction sender), `block_timestamp` (transaction timing), `transaction_hash` (unique transaction identifier), `user_type` (set to 'Transaction sender')

### Component B: Daily aggregation and deduplication
- **Purpose**: Aggregate user activity into daily buckets and count distinct users
- **Logic**: The system truncates block timestamps to day boundaries using daily time granularity, ensuring all transactions within a 24-hour period are grouped together. For each day, the system identifies all unique user addresses that sent at least one transaction, removing duplicates so that each address is counted only once per day regardless of how many transactions they sent. The system applies incremental processing logic to efficiently handle updates by focusing on recent days based on configurable lookback periods.
- **Key fields**: `timestamp` (daily boundary), `timestamp_grain` (set to 'day'), `user_dau` (the distinct user address count)

### Final aggregation
- **Combining components**: The user identification component feeds directly into the daily aggregation component, where transaction sender addresses are deduplicated within each day
- **Time aggregation**: Daily boundaries are established by truncating block timestamps to day granularity, ensuring consistent 24-hour periods for counting active users
- **Data quality**: Chain availability filters ensure that only valid and complete data is included in the final metric calculation
- **Final calculation**: The metric represents the count of distinct transaction sender addresses that were active on each day, providing a daily snapshot of unique user engagement on the Base blockchain
