# HYCHAIN Bridge deposits Methodology

## 1. Overview

Bridge deposits measures the total USD value of assets held in Hychain's bridge contract on Ethereum. This metric tracks the cumulative value of tokens that users have deposited to bridge from Ethereum to Hychain, representing the total value locked in the bridging infrastructure. The calculation focuses on a specific bridge address and aggregates all token balances held at that address over time.

## 2. Data sources

- **Ethereum token transfer events**: Parsed `Transfer` events for ERC-20 tokens to track token flows in and out of the bridge address
- **Ethereum native balance data**: ETH balance snapshots for the bridge address to capture native token holdings
- **End-of-day token price feeds**: USD price data for all tokens held in the bridge contract
- **Token metadata**: Contract addresses, decimal places, and symbol information for proper balance calculations
- **Chain availability data**: Configuration data to ensure proper data coverage and filtering

## 3. Step-by-step calculation

### Component A: Portfolio tracking
- **Purpose**: Calculate the total USD value of all tokens held at the bridge address over time
- **Logic**: Track all token balances at the bridge address `0x73c6af7029e714dff1f1554f88b79b335011da68` on Ethereum. This involves monitoring token transfer events to determine net inflows and outflows, maintaining running balances for each token type, and applying proper decimal adjustments based on token specifications
- **Key fields**: Bridge address `account_address`, token contract addresses, raw token `balance` amounts, and timestamp information

### Component B: Business data enrichment
- **Purpose**: Add categorical metadata for business reporting and segmentation
- **Logic**: Enrich the portfolio data with business classification fields including `market_sector_id` set to 'blockchains_l2' to categorize this as Layer 2 blockchain data, `business_segment_id` set to 'blockchain' for segment classification, and `product_id` set to null since this represents infrastructure-level data rather than specific products
- **Key fields**: Business classification dimensions and aggregated `bridge_deposits` values

### Final aggregation
- **Combining components**: Sum all token balances across different token types at the bridge address to get total portfolio value
- **Currency conversion**: Convert token balances to USD using end-of-day price feeds, applying appropriate decimal adjustments for each token type
- **Time aggregation**: Group data by timestamp and timestamp_grain (daily, weekly, monthly) while maintaining chain_id for proper segmentation
- **Final calculation**: The final `bridge_deposits` value represents the total USD value of all tokens held at the Hychain bridge address, with data gaps filled using forward-fill strategy to ensure continuous time series data and chain availability filtering applied to maintain data quality standards
