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 Contract deployers Methodology

## 1. Overview

The Optimism contract deployers metric measures the daily count of unique addresses that deployed smart contracts on the Optimism Layer 2 network. This metric tracks ecosystem development activity by counting how many distinct developers, projects, or automated systems deployed new contracts each day. The calculation aggregates contract creation events from Optimism blockchain transaction traces and counts unique deployer addresses per day, providing insight into development activity and platform adoption.

## 2. Data sources

- **Optimism transaction traces**: Raw transaction execution traces from the Optimism Layer 2 blockchain that capture contract creation operations
- **Optimism contract creation events**: Processed contract deployment records derived from analyzing transaction traces to identify when new smart contracts are deployed
- **Optimism block data**: Block timestamps and metadata used for daily time boundary calculations

## 3. Step-by-step calculation

### Component A: Contract creation data extraction
- **Purpose**: Identifies and standardizes all contract creation events on Optimism
- **Logic**: Extracts contract creation records from raw Optimism blockchain data, capturing the `deployer_address` (the account that initiated the contract deployment), `contract_address` (the newly created contract), `creation_timestamp` (when the deployment occurred), and `creation_trace_address` (the specific trace location). The data is deduplicated using distinct selection to handle any duplicate records that might exist in the raw data processing.
- **Key fields**: `deployer_address`, `contract_address`, `creation_timestamp`, `creation_trace_address`

### Component B: Daily aggregation
- **Purpose**: Counts unique contract deployers per day
- **Logic**: Groups contract creation events by daily time boundaries using timestamp truncation to day level (00:00:00 UTC). For each day, counts the number of distinct `deployer_address` values, meaning if the same address deployed multiple contracts on the same day, it only counts once. Adds metadata classification fields including `chain_id` as optimism, `market_sector_id` as blockchains_l2, and `business_segment_id` as blockchain.
- **Key fields**: Daily `timestamp`, `contract_deployers` count, chain classification metadata

### Final aggregation
- **Combining components**: The daily aggregated data flows directly from the contract creation extraction without additional joining, as the metric focuses solely on deployer address counts per day
- **Currency conversion**: No currency conversion required as this is a count-based metric
- **Time aggregation**: Daily boundaries are established by truncating block timestamps to day level, ensuring all contract deployments within a 24-hour UTC period are grouped together
- **Final calculation**: The final metric value equals the count of distinct deployer addresses per day, with the `finalize_metric_contract_deployers` macro applying a fill zeros strategy to ensure continuous daily time series even for days with no contract deployments. Chain availability filtering excludes periods when Optimism data may be incomplete or unreliable.
