# Plasma Contract deployers Methodology

## 1. Overview

The contract deployers metric measures the number of unique addresses that deploy smart contracts on the Plasma blockchain each day. This metric provides insight into developer activity and ecosystem growth by tracking how many distinct entities are creating new smart contracts. The calculation identifies unique deployer addresses per day from contract creation events and counts them to produce a daily time series.

## 2. Data sources

The calculation relies on the following raw data sources:

- **Plasma blockchain contract creation records**: Complete records of all smart contract deployments on the Plasma blockchain, including deployer addresses, contract addresses, creation timestamps, and deployment metadata
- **Plasma transaction traces**: Detailed transaction execution traces that capture contract creation events and associated deployer information
- **Plasma block data**: Block timestamp information used for daily time boundary calculations

## 3. Step-by-step calculation

### Component A: Contract creation data extraction
- **Purpose**: Extracts and prepares raw contract creation data from the Plasma blockchain
- **Logic**: Retrieves all contract creation records from Plasma blockchain data, capturing the creation timestamp (as `block_timestamp`), the address of the account that deployed the contract (`deployer_address`), the address of the newly created contract (`account_address`), and additional metadata including `creation_trace_address`, `contract_bytecode`, and `creator_address`. The data uses distinct selection to ensure each contract creation is counted only once.
- **Key fields**: `block_timestamp` (contract creation time), `deployer_address` (the address that deployed the contract), `account_address` (the deployed contract address)

### Final aggregation
- **Time boundaries**: Contract creation timestamps are truncated to daily boundaries using day-level time truncation, ensuring all contracts created within the same calendar day are grouped together
- **Combining components**: The contract creation data is grouped by day along with dimensional identifiers including chain identifier (plasma), market sector (blockchains_l1), and business segment (blockchain)
- **Distinct counting**: For each day, the system counts the number of distinct deployer addresses that created contracts, ensuring that if the same address deploys multiple contracts in one day, it is counted only once as a single deployer
- **Metric standardization**: The finalize_metric_contract_deployers macro is applied with a fill_zeros strategy, which handles missing days by filling them with zero values and ensures consistent metric formatting and metadata
- **Data quality filtering**: Chain availability filtering is applied to ensure only valid data periods are included in the final metric output
- **Final calculation**: The daily contract deployers value represents the count of unique addresses that deployed at least one smart contract on that specific day
