# Hydration Active addresses (weekly) Methodology

## 1. Overview

Active addresses (weekly) measures the number of unique addresses that make a transaction with Hydration. This metric tracks user engagement across both the native Substrate and EVM-compatible layers of the protocol, including products such as Hydration DEX, Hydration Lending, and HOLLAR. By capturing unique transaction signers over a 7-day rolling window, the metric provides a standardized view of weekly network adoption and activity.

## 2. Data sources

- **Blockchain events**: `Executed` events from the `ethereum` pallet and extrinsic transaction data, covering Hydration Substrate and Hydration EVM

## 3. Step-by-step calculation

### Component A: Hydration Substrate activity tracking

- **Purpose**: Identify unique users performing native operations on the Substrate chain.
- **Logic**: Transaction senders are extracted from the extrinsics data. The sender identifier is parsed and identified as the unique user address for each transaction recorded on the Substrate layer.
- **Key fields**: `block_timestamp`, `user_address` (derived from extrinsic sender)

### Component B: Hydration EVM activity tracking

- **Purpose**: Identify unique users interacting with the EVM-compatible environment.
- **Logic**: `Executed` events from the `ethereum` pallet are filtered to isolate EVM transactions. The user address is extracted by parsing the first element of the event data array, representing the transaction initiator.
- **Key fields**: `block_timestamp`, `event_data` (used to extract user address)

### Component C: Deduplication and weekly aggregation

- **Purpose**: Calculate the total number of unique active users across the entire project.
- **Logic**: User addresses from both Substrate and EVM components are consolidated. A distinct count of addresses is calculated per 7-day window using UTC boundaries. The resulting values are aggregated at the chain and project levels, with zero-filling applied to any weeks where no activity is recorded.
- **Key fields**: `timestamp`, `user_address`
