# Astar Substrate Transaction count Methodology

## 1. Overview

Transaction count is defined as the total number of confirmed transactions added to the blockchain for Astar Substrate. This metric is utilized to reflect the level of active engagement and throughput on the network. It encompasses both native Substrate extrinsics and Ethereum-compatible (EVM) executions to provide a comprehensive view of network activity.

## 2. Data sources

- **Blockchain events**: `Executed` events from the `ethereum` pallet and native network extrinsics, covering Astar

## 3. Step-by-step calculation

### Component A: Astar Substrate native extrinsic extraction

- **Purpose**: Identify and capture native transactions occurring on the Substrate layer.
- **Logic**: All unique extrinsic identifiers are retrieved from the native network extrinsic logs. Each extrinsic represents a signed or unsigned instruction submitted to the blockchain, including asset transfers, staking operations, and governance actions.
- **Key fields**: `block_timestamp` and `extrinsic_id`.

### Component B: Astar Substrate EVM transaction parsing

- **Purpose**: Capture smart contract interactions and transactions executed within the Ethereum Virtual Machine environment.
- **Logic**: `Executed` events are parsed from the `ethereum` pallet to identify successful EVM transactions. A unique transaction identifier is constructed by concatenating the parent extrinsic ID with the specific event index. This ensures that individual EVM calls are uniquely identified even when multiple calls are contained within a single Substrate extrinsic.
- **Key fields**: `block_timestamp`, `extrinsic_id`, and `event_index`.

### Component C: Daily aggregation and normalization

- **Purpose**: Consolidate transaction data into daily metrics for the Astar Substrate product.
- **Logic**: Transaction identifiers from both the Substrate and EVM layers are combined into a single dataset. A distinct count of these identifiers is performed to calculate the total transaction volume, ensuring no double-counting of executions. The resulting totals are aggregated at a daily granularity based on UTC day boundaries.
- **Key fields**: `block_timestamp` and `extrinsic_id`.

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.
