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

Scroll is an L2 smart contract platform for decentralized applications on Ethereum. Scroll was founded by Sandy Peng, Haichen Shen, and Ye Zhang and launched in 2023.

SCR tokenholders own and govern the protocol. Scroll's investors include Polychain, Qiming Venture Partners, etc.

# Scroll Contracts deployed Methodology

## 1. Overview

The contracts deployed metric measures the daily number of new smart contracts deployed on the Scroll blockchain. This metric tracks developer activity and ecosystem growth by counting unique contract creation events that occur each day. The calculation aggregates contract deployment transactions from Scroll blockchain data, ensuring each contract is counted exactly once on its deployment date.

## 2. Data sources

- **Scroll contract creation data**: Records of all smart contracts deployed to the Scroll blockchain, including contract addresses, deployment timestamps, deployer information, and contract bytecode
- **Scroll transaction traces**: Execution traces that capture contract creation events and their context within transactions
- **Block timestamp data**: Scroll block-level timestamp information used to determine the exact timing of contract deployments
- **Contract deployment transactions**: Transaction records that resulted in new contract creation on the Scroll network

## 3. Step-by-step calculation

### Component A: Contract creation extraction
- **Purpose**: Identifies and extracts all unique contract deployment events from Scroll blockchain data
- **Logic**: Retrieves contract creation records from Scroll blockchain data sources, capturing the `creation_timestamp` as the deployment time, `contract_address` as the unique contract identifier, `deployer_address` as the account that initiated the deployment, and additional metadata like `creation_trace_address`, `contract_bytecode`, and `creator_address`. The process deduplicates records using distinct selection to ensure each contract deployment is counted only once, even if multiple records exist for the same contract creation event.
- **Key fields**: `creation_timestamp` for timing, `contract_address` for unique identification, `deployer_address` for deployer tracking, `creation_trace_address` for trace context, `contract_bytecode` for contract content, `creator_address` for creation context

### Component B: Daily aggregation
- **Purpose**: Groups contract deployments by day and counts the total number of contracts deployed per day
- **Logic**: Takes the contract creation data and truncates the `block_timestamp` (mapped from `creation_timestamp`) to daily boundaries using timestamp truncation. Groups all contract deployments by the truncated daily timestamp and applies a count aggregation to determine the total number of contracts deployed each day. Adds standardized metadata including chain identifier set to 'scroll', market sector set to 'blockchains_l2' for Layer 2 blockchain categorization, business segment set to 'blockchain', timestamp grain set to 'day', and product identifier set to null since this is a chain-level metric.
- **Key fields**: Truncated daily `timestamp`, `contracts_deployed` count, chain and sector metadata fields

### Final aggregation
- **Combining components**: The daily contract deployment counts are processed through a finalization macro that standardizes the metric output format and ensures data completeness
- **Currency conversion**: Not applicable - this is a count-based metric measuring number of contracts rather than monetary values
- **Time aggregation**: Contract deployments are aggregated to daily boundaries, with each contract counted on its deployment date based on block timestamp
- **Final calculation**: The final metric represents the total count of unique smart contracts deployed to the Scroll blockchain on each given day, with zero values filled for days when no contracts were deployed and chain availability filtering applied to ensure data quality during network downtime periods
