The platform utilizes smart contracts to automate trading processes and manage liquidity pools, where users can provide assets to earn trading fees. Aster generates revenue through transaction fees collected from trades executed on the platform, while liquidity providers earn yields from their contributed assets.

Aster operates as a decentralized exchange that enables users to trade cryptocurrencies without intermediaries through automated liquidity pools. The platform leverages blockchain technology to facilitate peer-to-peer trading while maintaining user custody of funds and eliminating the need for traditional order books.

Aster is a decentralized exchange (DEX) platform operating in the cryptocurrency ecosystem. The organization focuses on providing automated market maker (AMM) functionality for digital asset trading.

# Aster Notional trading volume Methodology

## 1. Overview

Notional trading volume is defined as the total value of derivative contracts executed on Aster. The protocol's capacity for fee and revenue generation is indicated by this metric, which reflects the total liquidity and trading activity present within the system. USD-pegged stablecoins (USDT and USDC) are used as the quote assets for all trading pairs on Aster, ensuring that the aggregated volume represents the total USD-denominated value of all trades.

## 2. Data sources

- **Off-chain data**: Daily OHLCV (Open, High, Low, Close, Volume) data is captured via API scrapers from the Aster Klines endpoint, covering all available trading pairs on the Aster DEX.

## 3. Step-by-step calculation

### Component A: Daily trading data extraction

- **Purpose**: Capture raw trading activity per symbol from the Aster DEX.
- **Logic**: Data is ingested from the Aster Klines API, which provides daily snapshots of trading activity. For each symbol, fields including the open time, base asset, and quote asset are extracted. Transaction-level metadata, such as the total number of trades and taker-buy volumes, is also retrieved to maintain a comprehensive record of daily activity.

### Component B: Quote asset volume identification

- **Purpose**: Isolate the USD value of trades for each pair.
- **Logic**: The notional value for each trading pair is derived from the quote asset volume field. Because all pairs on the Aster DEX are quoted in stablecoins, this volume represents the USD value of the contracts without the requirement for additional price conversions. The data is deduplicated based on the combination of symbol and opening timestamp to ensure accuracy.

### Component C: Daily aggregation and zero-filling

- **Purpose**: Consolidate trading values into a protocol-wide daily total.
- **Logic**: Individual quote asset volumes are summed across all active symbols for each 24-hour period. These values are grouped by timestamp (at daily granularity) and product. A zero-filling strategy is applied to the final time series to ensure that days with no recorded activity are correctly represented as zero. All amounts are normalized by decimal precision to provide the final notional trading volume.
