# XSwap Tradeable pairs Methodology

## 1. Overview

The tradeable pairs metric measures the cumulative number of unique trading pairs available on the Xswap decentralized exchange on the XDC blockchain. This metric tracks the growth of tradeable assets over time by counting new pair/pool creation events from both Uniswap v2-style and v3-style factory contracts. The calculation aggregates daily and provides a running total of all trading pairs that have been created since the protocol's inception, helping to understand the expansion of available trading options on the platform.

## 2. Data sources

- **XDC blockchain factory events**: Parsed `Factory_PairCreated_event` logs from v2-style factory contracts and `Factory_PoolCreated_event` logs from v3-style factory contracts on XDC blockchain
- **Token metadata**: Token information including symbols and decimal precision for creating human-readable pair names
- **Blockchain timestamps**: XDC block timestamps to determine when trading pairs were first created

## 3. Step-by-step calculation

### Component A: Trading pair extraction
- **Purpose**: Identifies all trading pair creation events from Xswap factory contracts
- **Logic**: Extracts pair creation events from both v2 and v3 factory contract versions on XDC blockchain. For v2 events, captures the `pair` address, `token0` and `token1` addresses with a fixed fee tier of 0.003 (3000 basis points divided by 10^6). For v3 events, captures the `pool` address, `token0` and `token1` addresses with variable `fee` tiers. Each event includes the block timestamp for temporal tracking
- **Key fields**: `account_address` (pair/pool contract address), `token0_address`, `token1_address`, `fee_tier`, `block_timestamp`, `chain`, `version`

### Component B: Token metadata enrichment
- **Purpose**: Enriches trading pairs with readable token information
- **Logic**: Joins each trading pair with token metadata to retrieve token symbols and decimal precision for both tokens in the pair. Creates human-readable account names by concatenating the two token symbols with a hyphen separator
- **Key fields**: `token0_decimals`, `token1_decimals`, `account_name` (formatted as 'TOKEN0-TOKEN1')

### Component C: First appearance tracking
- **Purpose**: Determines when each trading pair first appeared on the platform
- **Logic**: Groups all trading pair records by unique `account_address` and finds the earliest block timestamp for each pair. Truncates timestamps to day level to enable daily aggregation and removes duplicate pair appearances on the same day
- **Key fields**: `timestamp` (day-truncated first appearance date), `account_address`

### Component D: Daily pair counting
- **Purpose**: Counts new trading pairs created each day
- **Logic**: Groups first appearances by day and uses approximate count distinct to count the number of new unique trading pair addresses that appeared for the first time on each day. This provides daily incremental pair counts
- **Key fields**: `pair_count` (daily count of new pairs)

### Component E: Gap filling
- **Purpose**: Ensures continuous time series with no missing days
- **Logic**: Applies gap filling to insert zero values for any missing days between the first and last trading pair creation dates. This creates a complete daily time series where days with no new pairs are explicitly represented with zero counts
- **Key fields**: `pair_count` (with zeros filled for missing days)

### Final aggregation
- **Combining components**: Takes the gap-filled daily pair counts and applies a cumulative sum calculation
- **Time aggregation**: Operates at daily grain with day-truncated timestamps as the primary time dimension
- **Final calculation**: Uses a window function to calculate the running sum of `pair_count` over time, partitioned by chain and product_id, ordered by timestamp. This produces the cumulative total of tradeable pairs available on each day since the protocol's inception
