# Katana Chain Contracts deployed Methodology

## 1. Overview

Contracts deployed is measured as the number of unique smart contracts published onchain for Katana Chain. It is utilized as a proxy for the amount of new infrastructure or applications that are launched on the blockchain. This metric provides a high-level view of developer engagement and the growth of the Katana Chain ecosystem.

## 2. Data sources

- **Blockchain events**: Contract creation traces and deployment records from Katana Chain

## 3. Step-by-step calculation

### Component A: Contract creation extraction

- **Purpose**: Identify unique contract deployments on the network
- **Logic**: Data is retrieved from the underlying blockchain ledger specifically focusing on contract creation records. Distinct contract addresses are identified using their unique deployment traces, including the creation timestamp, deployer address, and contract bytecode.
- **Key fields**: `block_timestamp` (timing), `account_address` (unique contract identifier), `deployer_address` (originating account)

### Component B: Daily aggregation

- **Purpose**: Quantify deployments on a daily basis
- **Logic**: The total count of unique contract addresses is aggregated by day based on the block timestamp. Timestamps are truncated to UTC day boundaries to ensure consistent daily reporting.
- **Key fields**: `block_timestamp` (truncated to day), `contracts_deployed` (count of unique addresses)

### Component C: Finalization and zero-filling

- **Purpose**: Ensure data integrity and continuity
- **Logic**: The aggregated counts are cast to standardized numeric types. A zero-filling strategy is applied to ensure that days with no deployment activity are explicitly represented as zero rather than missing values. Data is further filtered based on chain availability and freshness metadata to ensure only verified records are included.
- **Key fields**: `timestamp` (UTC day), `contracts_deployed` (finalized count)

The network uses pessimistic proofs via the AgglayerGateway for settlement on Ethereum, with vault bridges for cross-chain asset transfers.

Katana Network provides a scalable execution environment connected to Ethereum through the Agglayer interoperability layer.
