# DeGate Bridge deposits Methodology

## 1. Overview

Bridge deposits measures the total USD value of tokens held in DeGate's bridge address on Ethereum. This metric tracks the amount of user funds deposited into the protocol's bridging infrastructure, providing insight into the capital locked in DeGate's layer 2 bridging solution. The calculation involves monitoring token balances at a specific bridge address and converting them to USD values using end-of-day price feeds.

## 2. Data sources

The calculation relies on several key data sources:
- **Ethereum blockchain events**: Parsed `Transfer` events from ERC-20 token contracts to track token movements in and out of the bridge address
- **Token metadata**: Token contract information including decimal precision and token symbols for proper balance calculations
- **End-of-day price feeds**: Daily USD price data for all tokens to enable currency conversion
- **Token balance data**: Derived token balance snapshots calculated from transfer event processing

## 3. Step-by-step calculation

### Component A: Bridge address identification
- **Purpose**: Identifies the specific DeGate bridge address to monitor
- **Logic**: The calculation targets the Ethereum address `0x54d7ae423edb07282645e740c046b9373970a168` as the primary bridge deposit address for DeGate protocol
- **Key fields**: The `account_addresses` configuration specifies the bridge address to track

### Component B: Portfolio calculation
- **Purpose**: Calculates the total token portfolio value held at the bridge address
- **Logic**: The portfolio calculation processes parsed `Transfer` events to track all token inflows and outflows for the specified bridge address. For each token, it maintains running balances by processing transfer events chronologically. The system identifies when tokens are transferred to the bridge address (deposits) and when tokens are transferred away (withdrawals), maintaining accurate balance snapshots over time
- **Key fields**: Key fields include `balance` for individual token amounts, `timestamp` for time tracking, and token identifiers for proper aggregation

### Component C: USD conversion and aggregation
- **Purpose**: Converts individual token balances to USD and aggregates into total portfolio value
- **Logic**: Each token balance is converted to USD using end-of-day price feeds matched to the appropriate timestamp. The conversion process applies proper decimal handling based on each token's decimal precision. All USD-converted token balances are then summed to calculate the total portfolio value at each timestamp
- **Key fields**: The `balance` field represents the USD value of all tokens, with proper decimal adjustment and price conversion applied

### Component D: Business metadata application
- **Purpose**: Adds protocol categorization and business context
- **Logic**: The metric is categorized with `market_sector_id` set to 'blockchains_l2' indicating this represents layer 2 blockchain infrastructure, and `business_segment_id` set to 'blockchain' for the broader blockchain category. The `product_id` is left null as this represents protocol-level bridge deposits rather than a specific product
- **Key fields**: Business classification fields include `market_sector_id`, `business_segment_id`, and `product_id`

### Final aggregation
- **Combining components**: The portfolio balances are grouped by timestamp, timestamp grain, chain, and business metadata fields, with individual token balances summed into the total `bridge_deposits` value
- **Currency conversion**: USD conversion occurs at the individual token level using end-of-day price feeds before aggregation
- **Time aggregation**: Data is aggregated by timestamp boundaries, typically daily intervals based on the timestamp grain
- **Final calculation**: The final bridge deposits metric represents the sum of all USD-converted token balances held at the DeGate bridge address at each point in time, with fill-forward logic applied to handle missing data points and maintain continuous time series reporting
