# Astar Staking Total value locked Methodology

## 1. Overview

Total value locked (TVL) in Astar Staking measures the aggregate value of assets committed to the dApp staking mechanism on the Astar Substrate network. This metric represents the total quantity of native assets that are actively locked or relocked by users to support decentralized applications and earn rewards. Astar Staking TVL serves as a primary indicator of ecosystem health and the level of economic alignment between users, developers, and the network.

## 2. Data sources

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

## 3. Step-by-step calculation

### Component A: Staking inflow tracking

- **Purpose**: Capture assets entering the staking system through locking or relocking actions
- **Logic**: `Locked` and `Relock` events are parsed from the `dappStaking` pallet. The staked quantities are extracted from the event data and aggregated to determine the daily gross inflows into the staking program.
- **Key fields**: `event_method` (identifying `Locked` and `Relock` actions) and `amount` (quantity of assets staked).

### Component B: Unstaking outflow tracking

- **Purpose**: Capture assets exiting the staking system
- **Logic**: `Unlocking` events are parsed from the `dappStaking` pallet. These values are extracted and treated as negative amounts to reflect the reduction in the total staked supply.
- **Key fields**: `event_method` (identifying `Unlocking` actions) and `amount` (quantity of assets unstaked).

### Component C: Cumulative balance and USD conversion

- **Purpose**: Calculate the total value of locked assets in USD
- **Logic**: Daily staking inflows and unstaking outflows are summed to determine the net daily change in balance. A running sum of these net changes is calculated to establish the total inventory of locked assets for any given day. The resulting quantities are normalized by decimal precision and multiplied by end-of-day asset prices. A fill-forward strategy is applied to maintain a continuous time series for the TVL metric.

Liquid staking

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.
