# Active users (daily) Methodology

## 1. Overview

Active users (daily) is defined as the number of unique addresses that perform revenue-generating or liquidity-providing transactions on PrimeFi Lending. Protocol engagement is captured through user interactions related to asset supply, debt management, and flash loan execution. This metric is utilized to assess the scale of the active user base and the frequency of protocol utilization within the XDC ecosystem.

## 2. Data sources

- **Blockchain events**: `Borrow`, `FlashLoan`, `Repay`, `Deposit`, and `Withdraw` events from `LendingPool` contracts on XDC

## 3. Step-by-step calculation

### Component A: PrimeFi Lending activity tracking

- **Purpose**: To identify all unique participant addresses involved in lending and borrowing operations.
- **Logic**: User addresses are extracted from `Borrow`, `Repay`, `Deposit`, and `Withdraw` events from `LendingPool` contracts. Specifically, the address responsible for the transaction is identified from the `user` field in these events. For flash loan transactions, the initiator address is captured from the `initiator` field in `FlashLoan` events. All identified addresses are standardized and indexed by their transaction timestamp and chain.
- **Key fields**: `user`, `initiator`, and `block_timestamp`

### Component B: Daily uniqueness and aggregation

- **Purpose**: To calculate the distinct count of active participants on a daily basis.
- **Logic**: Unique addresses are filtered and grouped within fixed 24-hour UTC windows. Each unique address is counted only once per day, regardless of the number of interactions or transaction types performed within that period. The resulting counts are aggregated to provide the active users (daily) metric. Data is subjected to chain-specific freshness filters to ensure only validated on-chain records are included in the final output.
