# Astar Substrate Contracts deployed Methodology

## 1. Overview

Contracts deployed measures the number of unique smart contracts published onchain. This metric serves as a proxy for the volume of new infrastructure and applications launched on Astar Substrate. It reflects developer activity and the growth of the ecosystem by quantifying the initialization of new programmable accounts.

## 2. Data sources

- **Blockchain events**: `NewAccount` events from `system` pallet and `Executed` events from `ethereum` pallet on Astar Substrate
- **External data**: Asset metadata for address normalization

## 3. Step-by-step calculation

### Component A: Identification of contract creations

- **Purpose**: To identify the initialization of new smart contract accounts on the network.
- **Logic**: `NewAccount` events from the `system` pallet are parsed to identify the creation of new addresses. The first element within the event data is extracted and designated as the contract address. Only events associated with a valid extrinsic ID are included to ensure that account creations are tied to verifiable onchain transactions.
- **Key fields**: `event_data` (containing the account address), `extrinsic_id` (transaction identifier)

### Component B: Deployment metadata enrichment

- **Purpose**: To associate contract creations with deployer information and EVM-layer context.
- **Logic**: `Executed` events from the `ethereum` pallet are joined with the previously identified account creations using the extrinsic ID as the common identifier. This process allows for the extraction of the signer address, which is designated as the deployer, and the corresponding EVM transaction hash. This enrichment step ensures that deployments triggered through the EVM-compatibility layer of Astar Substrate are accurately captured.
- **Key fields**: `signer_address` (deployer identification), `evm_hash` (EVM transaction reference)

### Component C: Aggregation and daily normalization

- **Purpose**: To generate a daily count of unique contract deployments.
- **Logic**: The identified contract addresses are deduplicated and aggregated by day. The total count of unique addresses is calculated for each 24-hour UTC period. For days where no deployment activity is detected, the metric is zero-filled to maintain a continuous time series.
- **Key fields**: `timestamp` (daily granularity), `contract_address` (unique identifier for counting)

Blockchains (L2)

Validators process transactions and receive fees from users (supply-side fees).

Astar is a collective driving web3 adoption by connecting people through blockchain technology, business innovation, decentralized applications, and seamless digital experiences in the Polkadot ecosystem. Astar was founded by Sota Watanabe and launched in 2021.

ASTR tokenholders own and govern the protocol. Part of the transaction fees is burned (revenue). Astar’s investors include Binance, Polychain Capital, Crypto.com, etc.
