# Prime Numbers Assets staked Methodology

## 1. Overview

Assets staked measures the total value of XDC tokens staked in Prime Numbers' Prime Staking protocol. The calculation leverages the 1:1 minting relationship between staked XDC and psXDC tokens - when users stake XDC, they receive an equivalent amount of psXDC tokens, and when they unstake, psXDC tokens are burned. By tracking the total supply of psXDC tokens over time, we can determine the total amount of XDC currently staked in the protocol.

## 2. Data sources

The calculation uses these underlying data sources:
- **XDC blockchain token transfer events**: Parsed `Transfer` events for the psXDC token to track minting and burning activities
- **Token metadata**: Token decimal information for proper amount calculations
- **End-of-day price feeds**: XDC token pricing data for USD conversion

## 3. Step-by-step calculation

### Component A: psXDC mint tracking
- **Purpose**: Captures when users stake XDC by tracking psXDC token mints
- **Logic**: Filters XDC token transfer events where the psXDC token (`0x9b8e12b0bac165b86967e771d98b520ec3f665a6`) is transferred from the null address (`0x0000000000000000000000000000000000000000`) to any recipient. This represents new psXDC tokens being minted when XDC is staked. Extracts the `block_timestamp`, `transaction_hash`, `log_index`, and transfer `value` from these events.
- **Key fields**: `block_timestamp` for timing, `value` for the amount of psXDC minted, `token_address` identifying the psXDC token

### Component B: psXDC burn tracking  
- **Purpose**: Captures when users unstake XDC by tracking psXDC token burns
- **Logic**: Filters XDC token transfer events where the psXDC token is transferred from any sender to the null address. This represents psXDC tokens being burned when users unstake their XDC. Uses the same event structure as mints but with opposite transfer direction.
- **Key fields**: `block_timestamp` for timing, `value` for the amount of psXDC burned, `token_address` identifying the psXDC token

### Component C: Net flow calculation
- **Purpose**: Combines mints and burns to calculate daily net changes in staked amounts
- **Logic**: Combines mint and burn events, treating burns as negative amounts and mints as positive amounts. Applies decimal correction using token metadata to ensure proper numerical representation. Aggregates these flows by day, summing all mints and burns that occurred on each date. Fills missing days with zero net flows to maintain continuous time series.
- **Key fields**: Daily `amount` representing net change in psXDC supply, `timestamp` for the date

### Component D: Total supply calculation
- **Purpose**: Calculates the running total of psXDC tokens in circulation, representing total staked XDC
- **Logic**: Applies a cumulative sum across the daily net flows, ordered by date, to calculate the total psXDC supply at each point in time. Since psXDC is minted 1:1 when XDC is staked and burned when unstaked, the total psXDC supply directly equals the total amount of XDC currently staked in the protocol.
- **Key fields**: `total_supply` representing total psXDC tokens outstanding and thus total staked XDC

### Final aggregation
- **Combining components**: Takes the calculated total supply from the psXDC tracking and applies it as the assets staked metric
- **Currency conversion**: Converts the XDC-denominated staked amounts to USD using end-of-day price feeds through the standard conversion process
- **Time aggregation**: Maintains daily granularity with forward filling for any missing dates using a fill zeros strategy
- **Final calculation**: The final metric represents the total USD value of XDC tokens staked in Prime Numbers' Prime Staking protocol at each date, calculated as the total psXDC supply multiplied by the end-of-day XDC price
