# Unique Network NFT Marketplace Trading volume Methodology

## 1. Overview

Trading volume measures the total value of NFT assets exchanged on the Unique Network NFT Marketplace. This metric reflects the notional value of all successful purchase transactions executed through the protocol's marketplace smart contracts. It serves as a primary indicator of marketplace liquidity, user activity, and the economic throughput of the Unique Network ecosystem.

## 2. Data sources

- **Blockchain events**: `TokenIsPurchased` events from `Market` contracts on Unique Network
- **External data**: End-of-day price feeds for settlement assets including Unique (UNQ), Polkadot (DOT), and Tether (USDT)

## 3. Step-by-step calculation

### Component A: Unique Network NFT Marketplace sale extraction

- **Purpose**: Capture the raw economic data from successful NFT purchase events.
- **Logic**: `TokenIsPurchased` events are parsed from `Market` contracts. For every transaction, the unit `price` and the `sales_amount` are extracted to determine the total transaction quantity. The `currency` identifier is also captured to identify the specific asset used for settlement.
- **Key fields**: `price`, `sales_amount`, and `currency`

### Component B: Asset normalization and mapping

- **Purpose**: Map settlement assets to metadata and normalize transaction values.
- **Logic**: Transaction currency identifiers are matched against an internal mapping table to associate each sale with its respective asset metadata, including decimal precision and price feed identifiers. The gross transaction value is calculated by multiplying the unit price by the sales quantity. This total is then normalized by decimal precision to adjust for different asset denominations.
- **Key fields**: `decimals` and `coingecko_id`

### Component C: USD conversion and aggregation

- **Purpose**: Convert normalized volumes to USD and aggregate data into daily intervals.
- **Logic**: The normalized asset volumes are multiplied by end-of-day price feeds corresponding to the settlement asset. Values are aggregated by day, chain, and product using UTC boundaries. A finalization process is applied to ensure data consistency, including the application of chain availability filters and zero-filling for periods without recorded activity.
