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 Coinbase Smart Wallet deployers Methodology

## 1. Overview

This metric measures the daily count of distinct addresses that deployed Coinbase smart wallets on the Base blockchain. The calculation identifies contract creation events where the creator is the official Coinbase smart wallet factory contract, then counts how many unique deployer addresses created these wallets each day. This metric tracks adoption of Coinbase's smart wallet infrastructure by measuring how many different addresses are actively deploying these wallets.

## 2. Data sources

The calculation uses the following raw data sources:
- **Base blockchain contract creation data**: Records of all contract deployments on Base including creation timestamps, contract addresses, deployer addresses, and creator addresses
- **Base blockchain transaction traces**: Underlying transaction data that captures contract creation events and their associated metadata
- **Block timestamp data**: Timestamp information from Base blockchain blocks to establish when contract creations occurred

## 3. Step-by-step calculation

### Component A: Contract creation filtering
- **Purpose**: Identifies all Coinbase smart wallet deployments from raw Base blockchain contract creation data
- **Logic**: Extracts contract creation records including `creation_timestamp`, `contract_address`, `deployer_address`, and `creator_address` from Base blockchain contract data. Applies a critical filter to include only contracts where the `creator_address` matches `0x0ba5ed0c6aa8c49038f819e587e2633c4a9f428a`, which is the official Coinbase smart wallet factory contract address. This filtering ensures only legitimate Coinbase smart wallet deployments are counted, excluding other contract types or unofficial wallet implementations.
- **Key fields**: `creation_timestamp` for timing, `deployer_address` for identifying unique wallet creators, `creator_address` for factory contract validation, and `contract_address` for the deployed wallet instance

### Component B: Daily aggregation and counting
- **Purpose**: Aggregates the filtered contract creations by day and counts distinct deployers
- **Logic**: Groups the filtered Coinbase smart wallet deployments by day using timestamp truncation on the `creation_timestamp` field. For each day, counts the number of distinct `deployer_address` values to determine how many unique addresses deployed Coinbase smart wallets. Adds standardized metadata fields including chain identifier ('base'), market sector ('blockchains_l2'), business segment ('blockchain'), and null product identifier.
- **Key fields**: Truncated `timestamp` for daily grouping, `coinbase_smart_wallet_deployers` containing the distinct count of deployer addresses

### Final aggregation
- **Combining components**: The daily aggregated data flows through the finalize metric macro which applies standardized formatting, data validation, and gap filling
- **Currency conversion**: Not applicable for this count-based metric
- **Time aggregation**: Data is aggregated at daily boundaries using timestamp truncation, with a zero-fill strategy applied for days with no smart wallet deployments to maintain continuous time series
- **Final calculation**: The final metric value represents the count of distinct addresses that deployed at least one Coinbase smart wallet contract on each given day, providing a measure of daily smart wallet adoption activity
