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.

# Astar Assets staked Methodology

## 1. Overview

The total value of ASTR assets locked in Astar Staking is measured by the assets staked metric. This metric is tracked by monitoring the cumulative balance of staked assets through staking and unstaking events on Astar Substrate. All dApp staking activities, including initial locks, relocks, and unlocking events, are captured to maintain an accurate running balance of total staked assets.

## 2. Data sources

- **Blockchain events**: `Locked`, `Relock`, and `Unlocking` events from `dappStaking` pallets, covering Astar Substrate
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Staking events extraction

- **Purpose**: dApp staking events from Astar Substrate are identified and extracted
- **Logic**: Events from Astar Substrate are filtered for those originating from the `dappStaking` pallet. Events with methods `Locked` and `Relock`, which represent positive staking actions, are captured. Staked amounts are extracted from the `event_data` array at index 1. Timestamps are truncated to daily boundaries for aggregation.
- **Key fields**: `timestamp`, `event_pallet`, `event_method`, `event_data`, `amount`

### Component B: Unstaking events extraction
- **Purpose**: dApp unstaking events from Astar Substrate are identified and extracted
- **Logic**: Events from Astar Substrate are filtered for those from the `dappStaking` pallet with the `Unlocking` method, which represents unstaking actions. Unstaked amounts are extracted from the `event_data` array at index 1. Timestamps are truncated to daily boundaries for aggregation.
- **Key fields**: `timestamp`, `event_pallet`, `event_method`, `event_data`, `amount`

### Component C: Balance movement aggregation

- **Purpose**: Staking and unstaking events are combined into net daily balance changes
- **Logic**: Staking events (positive amounts) are unioned with unstaking events (negative amounts) to create a comprehensive view of all balance movements. Data is grouped by daily timestamps and summed to calculate net daily balance changes, capturing the net effect of all staking and unstaking activity each day.
- **Key fields**: `timestamp`, `amount`

### Component D: Cumulative balance calculation

- **Purpose**: The running total of staked assets is calculated over time
- **Logic**: A cumulative sum window function, ordered by timestamp, is applied to daily net changes to calculate running total balances. Historical cumulative staked balances are maintained to represent the total assets staked at any point in time.
- **Key fields**: `timestamp`, `amount`

### Component E: USD conversion and aggregation

- **Purpose**: Staked balances are normalized and converted to USD
- **Logic**: The cumulative staked balance is used as the base for the final calculation. Raw asset amounts are normalized by decimal precision and converted to USD using end-of-day price feeds for the ASTR asset. Data is aggregated to daily boundaries with a forward-fill strategy applied for days with no activity. Total assets staked is represented as the USD value of ASTR assets locked in Astar Staking at each point in time.
