# Zora Bridge deposits Methodology

## 1. Overview

Bridge deposits represents the total USD value of assets held in Zora's bridging infrastructure addresses on Ethereum. This metric measures the amount of value locked in Zora's bridge contracts that facilitate transfers between Ethereum and the Zora network. It serves as an indicator of capital flowing into the Zora ecosystem and the utilization of Zora's bridging infrastructure.

## 2. Data sources

- **Ethereum transaction data**: Transaction records and account balance changes for tracking asset movements in and out of bridge addresses
- **Token balance snapshots**: Daily snapshots of token holdings for specific Ethereum addresses
- **End-of-day token price feeds**: USD price data for converting token balances to dollar values
- **Token metadata**: Token contract specifications including decimal places for proper balance calculations
- **Chain availability configuration**: Data quality periods defining when reliable data collection is available for different chains

## 3. Step-by-step calculation

### Component A: Portfolio tracking
- **Purpose**: Calculate daily token balances held by Zora's bridge addresses on Ethereum
- **Logic**: Track all token holdings for two specific Ethereum addresses (`0x1a0ad011913a150f69f6a19df447a0cfd9551054` and `0x3e2ea9b92b7e48a52296fd261dc26fd995284631`) that serve as Zora's bridge infrastructure. The system processes Ethereum transaction data to determine daily balance changes for all tokens held by these addresses, applying proper decimal adjustments based on each token's specifications
- **Key fields**: Daily `timestamp`, `chain` identifier, token `balance` amounts with proper decimal handling, and USD-converted values

### Component B: Business metadata addition
- **Purpose**: Add categorical metadata for business intelligence and data organization
- **Logic**: Enrich the portfolio data with business context by assigning `market_sector_id` as 'blockchains_l2' to categorize this as Layer 2 blockchain activity, `business_segment_id` as 'blockchain' to identify the core business area, and leaving `product_id` as null since this represents infrastructure-level bridge deposits rather than a specific product
- **Key fields**: `chain_id` from the source chain, categorical business identifiers for data segmentation

### Component C: Balance aggregation
- **Purpose**: Calculate total bridge deposit value across all tokens
- **Logic**: Sum all USD-converted token balances held by the bridge addresses to create a single daily `bridge_deposits` value. This aggregation combines holdings across all different tokens (ETH, ERC20 tokens, etc.) that may be deposited in the bridge contracts
- **Key fields**: Aggregated `bridge_deposits` representing total USD value locked in bridge infrastructure

### Final aggregation
- **Combining components**: The portfolio balances are aggregated by summing across all tokens for each day, creating a single bridge deposits value per timestamp
- **Currency conversion**: Token balances are converted to USD using end-of-day price feeds, with proper decimal adjustments applied based on each token's contract specifications
- **Time aggregation**: Data is organized by daily timestamps with a grain identifier for time-series processing
- **Final calculation**: The finalize metric macro applies time-series processing including forward-filling for missing days using the 'fill_forward' strategy, ensuring continuous data coverage. Chain availability filtering removes any data points that fall outside of reliable data collection periods for Ethereum, providing clean time-series data showing the daily USD value of assets locked in Zora's bridge infrastructure.
