# Hydration DEX Tradeable assets Methodology

## 1. Overview

Tradeable assets measures the number of unique assets available for trading on Hydration DEX. This metric reflects the breadth of token coverage across the project's various liquidity structures, including the Omnipool, Isolated pools, and Stablepools. It serves as a key indicator of the platform's asset diversity and the range of trading pairs accessible to users.

## 2. Data sources

- **Blockchain events**: Reserve states and balance updates from Omnipool, Isolated pool, and Stablepool contracts on Hydration Substrate
- **External data**: Asset metadata for decimal normalization and token identification

## 3. Step-by-step calculation

### Component A: Liquidity pool reserve extraction

- **Purpose**: Identify all active assets held within the different liquidity pool types of Hydration DEX.
- **Logic**: Reserve data is extracted for the Hydration Omnipool, Isolated pools, and Stablepools. For the GDOT stablepool, specific aDOT balances are retrieved from the contract address `167UdiHenqFRAFeb8GxRYGT89BpKi2VPDnUjDFT8H8efqueB`. These records provide the baseline list of token addresses currently supporting trading activity.
- **Key fields**: `token_address`, `pool_address`, `net_deposits`

### Component B: Asset filtering and deduplication

- **Purpose**: Ensure only valid tradeable assets are included in the final count.
- **Logic**: Token addresses are consolidated across all pool types. A specific filter is applied to the Hydration Omnipool to exclude the H2O asset (identified by token address `1`). Amounts are normalized by decimal precision to ensure only assets with valid balances are considered.
- **Key fields**: `token_address`, `pool_type`

### Component C: Daily unique asset aggregation

- **Purpose**: Calculate the final daily count of tradeable assets.
- **Logic**: The number of unique token addresses is counted on a daily basis. The results are grouped by timestamp and chain. A zero-filling strategy is applied to ensure continuity in the time series data, representing the total breadth of the Hydration DEX ecosystem for each UTC day.
- **Key fields**: `timestamp`, `chain_id`, `tradeable_assets`
