# ComTech Total value locked Methodology

## 1. Overview

ComTech's Total Value Locked (TVL) represents the USD value of all outstanding stablecoins issued by ComTech across supported blockchain networks. The metric is calculated by tracking the net issuance (mints minus burns) of ComTech's ComTech Gold stablecoin on the XDC network and converting the outstanding supply to USD value. This metric provides insight into the total capital locked in ComTech's stablecoin ecosystem.

## 2. Data sources

The calculation relies on the following raw data sources:
- **XDC network token transfer events**: Parsed `Transfer` events from the XDC blockchain for the ComTech Gold token contract (`0x8f9920283470f52128bf11b0c14e798be704fd15`)
- **End-of-day token price feeds**: Daily USD price data for accurate currency conversion
- **Token metadata**: Token-specific information including decimal places and symbols for proper value normalization

## 3. Step-by-step calculation

### Component A: Stablecoin mints extraction
- **Purpose**: Identifies new token issuance events on the blockchain
- **Logic**: Extracts token transfer events where the `from_address` is the null address (`0x0000000000000000000000000000000000000000`), indicating new tokens being minted into circulation. Events are filtered to include only the specific ComTech Gold token contract address and exclude any removed/invalid log entries. Each mint event captures the `block_timestamp`, `transaction_hash`, `log_index`, recipient address (`to_address`), token contract address, and the minted `amount`
- **Key fields**: `block_timestamp` for timing, `amount` for quantity minted, `to_address` for recipient, and `token_address` for token identification

### Component B: Stablecoin redemptions extraction  
- **Purpose**: Identifies token burn/redemption events that reduce circulating supply
- **Logic**: Extracts token transfer events where the `to_address` is either the null address (`0x0000000000000000000000000000000000000000`) or the dead address (`0x000000000000000000000000000000000000dead`), indicating tokens being permanently removed from circulation. Uses the same filtering criteria as mints to ensure data quality and consistency
- **Key fields**: `block_timestamp` for timing, `amount` for quantity burned, `from_address` for the burning entity, and `token_address` for token identification

### Component C: Outstanding supply calculation
- **Purpose**: Calculates the net circulating supply by combining mints and burns
- **Logic**: Combines mint and burn events into a single dataset, with burn amounts converted to negative values to represent supply reduction. Daily aggregation is performed by truncating timestamps to day boundaries. Decimal corrections are applied using token metadata to ensure proper value representation. A cumulative sum is calculated using window functions, ordered by timestamp and partitioned by chain and token address, to determine the running outstanding supply over time
- **Key fields**: `timestamp` (daily), `chain`, `product_id`, `token_address`, `outstanding_supply` (cumulative amount)

### Component D: Forward filling and gap handling
- **Purpose**: Ensures continuous time series data with no missing days
- **Logic**: Identifies gaps in the daily time series and forward-fills the most recent outstanding supply value to maintain data continuity. This ensures that weekends, holidays, or periods with no blockchain activity still have supply values representing the unchanged circulating amount
- **Key fields**: All dimension fields plus forward-filled `outstanding_supply` values

### Final aggregation
- **Combining components**: The outstanding supply values are aggregated by summing across all tokens and chains for each day, though currently ComTech only operates ComTech Gold on XDC network
- **Currency conversion**: Outstanding supply amounts are converted to USD using end-of-day token price feeds, applying the appropriate exchange rate for each day
- **Time aggregation**: Data is maintained at daily granularity with timestamp boundaries set to day precision
- **Final calculation**: The TVL metric represents the sum of all outstanding stablecoin supply values converted to USD, providing the total value locked in ComTech's stablecoin ecosystem
