# XSwap Tradeable assets Methodology

## 1. Overview

The XSwap tradeable assets metric measures the cumulative number of unique tokens that can be traded on the XSwap decentralized exchange. This metric tracks the growth in trading diversity by counting each unique token address the first time it appears in any trading pair or liquidity pool. The calculation processes XSwap factory contract events to identify when new trading pairs are created, extracts the token addresses from these pairs, and maintains a running total of unique tradeable assets over time.

## 2. Data sources

- **XDC blockchain events**: Parsed `Factory_PairCreated_event` logs from XSwap v2 factory contracts containing trading pair creation data with token addresses and fee information
- **XDC blockchain events**: Parsed `Factory_PoolCreated_event` logs from XSwap v3 factory contracts containing liquidity pool creation data with token addresses and fee tier information  
- **Token metadata**: Token reference data providing symbols, decimal precision, and other token characteristics for XDC chain tokens
- **End-of-day price feeds**: Token price data to support potential USD conversion requirements

## 3. Step-by-step calculation

### Component A: Trading pair extraction
- **Purpose**: Extracts all token addresses that participate in XSwap trading pairs or liquidity pools
- **Logic**: Processes XSwap factory contract events from both v2 (pair creation) and v3 (pool creation) versions on XDC chain. For v2, extracts `token0` and `token1` addresses from `Factory_PairCreated_event` logs along with the created `pair` contract address. For v3, extracts `token0` and `token1` addresses from `Factory_PoolCreated_event` logs along with `fee` tier and created `pool` contract address. Enriches this data with token metadata including symbols and decimals. Uses UNION ALL to combine both tokens from each pair, effectively doubling the records to capture each token separately.
- **Key fields**: `block_timestamp` for timing, `token0_address` and `token1_address` for the tradeable tokens, `chain` identifier, version information, and token symbols for naming

### Component B: First appearance tracking  
- **Purpose**: Identifies when each unique token first became tradeable on XSwap
- **Logic**: Groups all token appearances by token address and chain, then finds the minimum timestamp when each token first appeared in any trading pair or pool. This ensures each token is only counted once regardless of how many different pairs it participates in. Timestamps are truncated to day level for daily boundary consistency.
- **Key fields**: Minimum `timestamp` per token, `token_address` as the unique identifier, `chain` for multi-chain support

### Component C: Daily new asset counting
- **Purpose**: Counts how many new unique tokens became tradeable on each day
- **Logic**: Groups the first appearances by date and counts the distinct number of token addresses that had their first appearance on each specific day. This creates a time series showing the daily addition of new tradeable assets to the XSwap ecosystem.
- **Key fields**: Daily `timestamp`, `asset_count` representing new tokens added that day

### Component D: Time series gap filling
- **Purpose**: Ensures complete daily time series with no missing dates
- **Logic**: Applies gap-filling logic to insert zero values for any dates where no new tokens were added, maintaining continuity in the daily time series. This prevents issues in downstream cumulative calculations that could occur with sparse data.
- **Key fields**: Complete daily `timestamp` series, `asset_count` with zeros filled for missing dates

### Final aggregation
- **Combining components**: The gap-filled daily new asset counts are processed through a cumulative sum calculation
- **Time aggregation**: Data is aggregated at daily boundaries using day-truncated timestamps
- **Final calculation**: A window function calculates the running total of unique tradeable assets by summing all daily additions from the beginning of time up to each date, partitioned by chain and product to support multi-chain scenarios. The result shows the cumulative number of unique tokens that have ever been tradeable on XSwap as of each date.
