# AlienX Bridge deposits Methodology

## 1. Overview

AlienX bridge deposits measures the total USD value of tokens held in AlienX's Ethereum bridge addresses. This metric tracks the aggregate value of user deposits that have been bridged to the AlienX L2 network, providing insight into the total value locked in the bridging infrastructure. The calculation monitors specific Ethereum addresses that serve as deposit contracts for the AlienX bridge, aggregating token balances across all deposited assets.

## 2. Data sources

The calculation relies on several key data sources:

- **Ethereum token transfer events**: Parsed `Transfer` events from ERC-20 tokens and ETH transfers to track all inflows and outflows from the bridge addresses
- **Ethereum transaction data**: Transaction records providing context for transfer events and ensuring data completeness
- **End-of-day token price feeds**: USD pricing data for all tokens held in the bridge addresses to enable value aggregation
- **Token metadata**: Decimal places, symbols, and contract addresses for proper token amount normalization
- **Daily balance snapshots**: Historical balance data to maintain accurate running totals over time

## 3. Step-by-step calculation

### Component A: Portfolio balance tracking
- **Purpose**: Calculate token balances held in AlienX bridge addresses over time
- **Logic**: The system monitors two specific Ethereum addresses (`0x69ab55146bc52a0b31f74dbdc527b8b7e9c7c27c` and `0x5625d2a46fc582b3e6de5288d9c5690b20ebdb8d`) that serve as AlienX's bridge deposit contracts. For each address, the calculation processes all token transfer events to track balance changes. Inbound transfers increase balances while outbound transfers decrease them. The system maintains running balances for each token-address combination by applying cumulative sum logic to the net transfer amounts. Token amounts are normalized using the appropriate decimal places from token metadata.
- **Key fields**: Important fields include `timestamp` for temporal tracking, `chain` identifier, `balance` amounts for each token, and address identifiers for the monitored contracts

### Component B: Business categorization
- **Purpose**: Apply Token Terminal's business taxonomy to the bridge deposit data
- **Logic**: The portfolio balance data is enhanced with business-relevant metadata. Each record is categorized with `market_sector_id` set to "blockchains_l2" to identify AlienX as a Layer 2 solution, and `business_segment_id` set to "blockchain" to classify it within the blockchain infrastructure category. The `product_id` is left null as this metric represents the overall bridge functionality rather than a specific product. Token balances are aggregated across all tokens for each timestamp and chain combination to produce total bridge deposit values.
- **Key fields**: The categorization adds `market_sector_id`, `business_segment_id`, `product_id` fields, while `bridge_deposits` represents the aggregated balance value

### Final aggregation
- **Combining components**: The business-categorized portfolio data flows into the finalization process where multiple transformations occur simultaneously
- **Currency conversion**: Token balances are converted to USD using end-of-day price feeds, with each token's balance multiplied by its corresponding daily closing price
- **Time aggregation**: Data is processed with daily timestamp boundaries, ensuring consistent temporal granularity across the metric
- **Final calculation**: The final bridge deposits value represents the sum of all USD-converted token balances held across both monitored bridge addresses. Missing data points are handled using a fill-forward strategy, where the most recent available value is carried forward to maintain data continuity. Chain availability filters are applied to ensure only valid chain data is included in the final output.
