# Constant Product xRex staked Methodology

## 1. Overview

xRex staked measures the total USD value of xRex assets deposited into the staking and governance modules of Constant Product. This metric provides a view into the total amount of capital committed to the protocol's governance system. Values are calculated by tracking the cumulative balance of staking and unstaking actions across all participating accounts.

## 2. Data sources

- **Blockchain events**: `Deposit` and `Withdraw` events from `VoteModule` contracts, covering Linea
- **External data**: Asset metadata for decimal normalization and end-of-day price feeds for the xRex asset

## 3. Step-by-step calculation

### Component A: Staking and unstaking event extraction

- **Purpose**: Capture all ledger-altering actions related to xRex staking
- **Logic**: `Deposit` events (representing stakes) and `Withdraw` events (representing unstakes) are parsed from `VoteModule` contracts. For each event, the account address, token address, and transaction amounts are extracted. Data is filtered to exclude events where the removed flag is set to true.
- **Key fields**: `in_amount` (quantity of assets), `in_from` (account address), `block_timestamp` (event timing)

### Component B: User-level balance calculation

- **Purpose**: Determine the daily running balance of staked assets for every unique user
- **Logic**: Stake events are assigned positive values, while unstake events are assigned negative values. These quantities are aggregated by account address, chain, and day. A cumulative sum of these daily deltas is calculated per user to establish the total staked balance over time. A fill-forward operation is applied to ensure user balances are carried over to subsequent days even when no new transactions occur.
- **Key fields**: `account_address`, `token_address`, `outstanding_delta` (daily change)

### Component C: Aggregation and USD conversion

- **Purpose**: Normalize quantities to a final USD valuation at the protocol level
- **Logic**: Individual user balances are summed by day to calculate the total protocol-wide staked supply. These raw amounts are normalized by decimal precision using asset metadata. The resulting quantities are multiplied by end-of-day price feeds to determine the total USD value. Daily values are calculated using UTC day boundaries.
- **Key fields**: `xrex_staked` (total quantity), `price_usd` (valuation)
