# Aevo Bridge deposits Methodology

## 1. Overview

Bridge deposits for Aevo represents the total USD value of assets held in Aevo's bridge deposit addresses on Ethereum. This metric tracks the amount of funds that users have deposited to Aevo's bridge infrastructure, providing insight into the protocol's total value locked in bridge operations. The calculation involves monitoring specific Ethereum addresses identified as Aevo's bridge deposit wallets, tracking all token holdings across these addresses, and converting the total value to USD using end-of-day pricing data.

## 2. Data sources

The calculation relies on several key data sources:
- **Ethereum blockchain data**: Transaction traces and state changes to track balance movements in the target bridge addresses
- **Token transfer events**: Parsed `Transfer` events from Ethereum to identify token movements into and out of bridge addresses
- **Token balance snapshots**: Daily balance data for all tokens held in the monitored addresses
- **Token metadata**: Contract information including token decimals, symbols, and contract addresses for proper balance calculation
- **End-of-day price feeds**: Daily USD prices for all tokens held in the bridge addresses to enable accurate value conversion
- **Chain availability data**: Configuration data to ensure metric coverage aligns with supported blockchain networks

## 3. Step-by-step calculation

### Component A: Address identification
- **Purpose**: Identifies the specific Ethereum addresses that serve as Aevo's bridge deposit wallets
- **Logic**: Two hardcoded Ethereum addresses are defined as the target bridge addresses: `0x4082c9647c098a6493fb499eae63b5ce3259c574` and `0x787a0acab02437c60aafb1a29167a3609801e320`. These addresses represent Aevo's official bridge infrastructure where user deposits are held.
- **Key fields**: The `account_addresses` configuration specifies exactly which addresses to monitor for bridge deposit activity

### Component B: Portfolio balance calculation
- **Purpose**: Calculates the total USD value of all tokens held across the bridge addresses over time
- **Logic**: For each target address and each day, the system identifies all token holdings by tracking balance changes through transaction traces and transfer events. Token balances are converted to their proper decimal representation using token metadata, then converted to USD values using end-of-day price feeds. The calculation captures balances for all ERC-20 tokens and native ETH held in these addresses.
- **Key fields**: Key outputs include `timestamp` for the calculation date, `chain` identifying Ethereum, and `balance` representing the USD value of holdings

### Component C: Business metadata assignment
- **Purpose**: Adds Token Terminal's standard business classification dimensions to the metric
- **Logic**: Each calculated balance record is enriched with business metadata to properly categorize the metric within Token Terminal's taxonomy. The metric is classified with `chain_id` set to the source blockchain, `market_sector_id` as 'blockchains_l2' to indicate this is layer-2 related infrastructure, `business_segment_id` as 'blockchain' to categorize the business type, and `product_id` as null since this represents protocol-level bridge activity rather than a specific product.
- **Key fields**: Business dimensions include `market_sector_id`, `business_segment_id`, and `product_id` for proper metric classification

### Final aggregation
- **Combining components**: Balance values are summed across all tokens and addresses for each timestamp and time grain, creating a single bridge deposits value per time period
- **Currency conversion**: All token balances are converted to USD using end-of-day price feeds, with proper decimal adjustment based on each token's contract specifications
- **Time aggregation**: Data is grouped by `timestamp` and `timestamp_grain` to support multiple time period views (daily, weekly, monthly)
- **Final calculation**: The final bridge deposits metric represents the total USD value of all assets held across Aevo's bridge deposit addresses at each point in time, with a fill-forward strategy applied to handle any missing data points in the time series and chain availability filtering to ensure data quality standards
