# Etherex xRex supply Methodology

## 1. Overview

XREX supply tracks the total outstanding supply of XREX tokens on the Etherex protocol. This metric measures the circulating supply by tracking all mint and burn events for the XREX token contract on Linea blockchain. The calculation follows the ERC-20 standard approach where minting involves transfers from the zero address and burning involves transfers to the zero address. This provides a real-time view of token supply changes over time.

## 2. Data sources

- **Linea token transfer events**: Parsed `Transfer` events from the Linea blockchain for the XREX token contract (`0xc93b315971a4f260875103f5da84cb1e30f366cc`)
- **ERC-20 standard events**: Token transfer logs that include mint operations (transfers from zero address) and burn operations (transfers to zero address)

## 3. Step-by-step calculation

### Component A: XREX mint event identification
- **Purpose**: Identifies all XREX token minting transactions
- **Logic**: Filters Linea token transfer events where the `from_address` equals the zero address (`0x0000000000000000000000000000000000000000`) and the `token_address` matches the XREX contract address. These represent new tokens being created and added to circulation.
- **Key fields**: `block_timestamp` for timing, `transaction_hash` and `log_index` for unique identification, `value` for mint amount, and standard metadata including chain (`linea`), product (`Constant Product`), and token address

### Component B: XREX burn event identification  
- **Purpose**: Identifies all XREX token burning transactions
- **Logic**: Filters Linea token transfer events where the `to_address` equals the zero address and the `token_address` matches the XREX contract address. These represent tokens being permanently removed from circulation.
- **Key fields**: Same structure as mint events but representing tokens being destroyed rather than created

### Component C: Supply change calculation
- **Purpose**: Combines mint and burn events to calculate net supply changes
- **Logic**: Unions mint events (with positive amounts) and burn events (with negative amounts by multiplying burn amounts by -1). Groups the combined data by day using timestamp truncation to daily granularity, then sums all amounts within each day to get the net supply change.
- **Key fields**: Daily `timestamp`, net `outstanding_delta` representing the sum of mints minus burns for each day

### Component D: Cumulative supply tracking
- **Purpose**: Calculates the running total of outstanding XREX supply over time
- **Logic**: Applies a cumulative sum window function over the daily supply changes, partitioned by chain and token address and ordered chronologically by timestamp. This creates a running total that represents the outstanding supply at each point in time.
- **Key fields**: `outstanding_supply` representing the cumulative total of all historical mints minus burns

### Final aggregation
- **Combining components**: The daily supply changes are processed through a cumulative sum calculation to produce the total outstanding supply for each day
- **Currency conversion**: No USD conversion is applied as this tracks token quantity rather than value
- **Time aggregation**: Daily boundaries are established by truncating block timestamps to day level, with forward-filling applied to ensure continuous daily data
- **Final calculation**: Outstanding supply equals the cumulative sum of all daily net supply changes (mints minus burns) from the token's inception to each given date
