# Mantra Zone Tradeable assets Methodology

## 1. Overview

Tradeable assets measures the total number of unique assets that can be traded on Mantra Zone. This metric reflects the breadth of token coverage and the diversity of the ecosystem supported by the decentralized exchange. By tracking the cumulative growth of unique assets appearing in swap operations, the maturity and expansion of the platform's liquidity pools are quantified.

## 2. Data sources

- **Blockchain events**: `wasm` events from Mantra Zone contracts, covering Mantra
- **External data**: Asset metadata for token identification and decimal normalization

## 3. Step-by-step calculation

### Component A: Swap event extraction

- **Purpose**: Identify all unique assets participating in exchange activities.
- **Logic**: `wasm` events are parsed from the Mantra Zone exchange contract where the action is defined as `execute_swap_operations`. The specific token addresses for both the incoming and outgoing assets are extracted from the event attributes for every successful transaction.
- **Key fields**: `token_in`, `token_out`, and `block_timestamp`

### Component B: Asset discovery tracking

- **Purpose**: Determine the point in time when an asset first becomes available for trading.
- **Logic**: The earliest block timestamp for every unique asset address is identified across all historical swap data. This first appearance date is established as the entry point for the asset into the tradeable catalog.
- **Key fields**: `token_address` and `first_appearance` (minimum timestamp)

### Component C: Cumulative aggregation

- **Purpose**: Calculate the total number of tradeable assets for any given date.
- **Logic**: A running total of unique asset addresses is calculated by counting all assets whose first appearance occurs on or before the reporting date. This cumulative count is aggregated at a daily granularity. In instances where no new assets are discovered on a specific day, the value is forward-filled to maintain a continuous time series.
- **Key fields**: `tradeable_assets` (cumulative count) and `timestamp`
