# Hydration DEX Total value locked Methodology

## 1. Overview

Total value locked (TVL) measures the total value of assets deposited into Hydration DEX liquidity pools. This metric accounts for liquidity across the Omnipool, stablepools, and isolated pools on the protocol. It serves as a leading indicator for the platform's trading capacity and market-making depth. Assets are denominated in their native units and converted to USD using end-of-day price feeds.

## 2. Data sources

- **Blockchain events**: Asset reserve and balance states from `Omnipool`, `Stablepool`, and `Isolated Pool` contracts on Hydration Substrate
- **External data**: End-of-day price feeds for deposited assets

## 3. Step-by-step calculation

### Component A: Omnipool reserve tracking

- **Purpose**: Captures liquidity within the primary Hydration Omnipool.
- **Logic**: Asset reserves are extracted from `Omnipool` contracts. Balances for all supported assets are identified and aggregated. The H2O asset is explicitly excluded from the Omnipool reserve calculation to ensure data consistency.
- **Key fields**: `reserve_0`, `reserve_1`, `token_address`

### Component B: Stablepool and Isolated Pool reserve tracking

- **Purpose**: Captures liquidity from specialized stable and isolated trading pairs.
- **Logic**: Asset balances are retrieved for `Stablepool` and `Isolated Pool` contracts. This includes the specific tracking of aDOT balances within the GDOT stablepool. Reserves for each token in every pool are aggregated on a daily basis.
- **Key fields**: `reserve_0`, `reserve_1`, `pool_address`, `token_address`

### Component C: USD conversion and final aggregation

- **Purpose**: Normalizes all pool reserves to USD for unified reporting.
- **Logic**: Daily average reserves are calculated for all identified pools. Amounts are normalized by decimal precision and multiplied by end-of-day price feeds for each respective asset. Total TVL for Hydration DEX is calculated as the sum of all USD-denominated net deposits across the Omnipool, stablepools, and isolated pools.
- **Key fields**: `net_deposits`, `price_usd`, `timestamp`
