# Active users (weekly) Methodology

## 1. Overview

Active users (weekly) measures the number of unique addresses that perform revenue-generating transactions on Euler Lending. This metric captures core lending activities, including the provision of liquidity and the utilization of credit markets across various decentralized vaults. Active users (weekly) serves as a primary indicator of protocol adoption and user engagement within the Euler Lending ecosystem.

## 2. Data sources

- **Blockchain events**: `Deposit`, `Withdraw`, `Repay`, and `Borrow` events from `EVault` contracts, covering Ethereum, Base, Sonic, Avalanche, and 6 other chains

## 3. Step-by-step calculation

### Component A: Extraction of lending interactions

- **Purpose**: To identify all relevant user interactions within the lending protocol.
- **Logic**: `Deposit`, `Withdraw`, `Repay`, and `Borrow` events are parsed from `EVault` contracts across all supported chains. These events are filtered to ensure only transactions related to Euler Lending are included in the dataset.
- **Key fields**: `transaction_hash`, `block_timestamp`, and `chain`.

### Component B: User address identification

- **Purpose**: To map specific transaction participants to unique user addresses.
- **Logic**: For `Deposit` and `Withdraw` events, the user address is extracted from the `owner` parameter. For `Repay` and `Borrow` events, the user address is extracted from the `account` parameter. This ensures that the primary actor responsible for the capital movement or debt obligation is correctly identified.
- **Key fields**: `owner` and `account`.

### Component C: Weekly aggregation

- **Purpose**: To calculate the final count of unique participants per 7-day window.
- **Logic**: User addresses are aggregated per 7-day window, chain, and product. Unique addresses are deduplicated within a 7-day rolling window to determine the weekly active user count. Results are filtered to remove any internal protocol addresses or system-level interactions that do not represent unique end-user activity.

Lending

Lenders deposit funds into Euler and receive interest payments from borrowers (supply-side fees).

Euler is a non-custodial lending protocol built on Ethereum. Euler was founded by Michael Bentley, Doug Hoyte & Jack Prior and launched in 2021.

EUL tokenholders own and govern the protocol. They currently take a cut of the total interest paid by borrowers (revenue). Euler’s investors include Paradigm, Lemniscap, Launchhub Ventures, etc.
