Gravity Alpha batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense).

Gravity Alpha is an L2 smart contract platform for decentralized applications on Ethereum. Gravity Alpha was founded by Galxe and launched in 2024.

G tokenholders own and govern the protocol. Galxe's investors include Arbitrum Foundation, Multicoin Capital, Dragonfly Capital, etc.

# Gravity Alpha Mainnet Bridge deposits Methodology

## 1. Overview

Bridge deposits represents the total USD value of tokens held in GravityAlpha's bridging infrastructure addresses. This metric tracks the assets deposited by users that are available for bridging operations, providing insight into the protocol's liquidity reserves and user deposit activity. The calculation involves monitoring token balances at specific bridge contract addresses and converting them to USD values using daily price feeds.

## 2. Data sources

The calculation relies on several key data sources:
- **Ethereum blockchain state data**: Token balance snapshots and account state changes for tracking ERC-20 token holdings
- **Ethereum transaction logs**: `Transfer` events and other token-related events to track balance changes over time  
- **Token metadata**: Contract addresses, decimal places, and token symbols for proper balance calculation and normalization
- **End-of-day price feeds**: Daily token prices for USD conversion of held assets
- **Chain availability data**: Blockchain data quality and availability windows for filtering reliable data periods

## 3. Step-by-step calculation

### Component A: Portfolio balance tracking
- **Purpose**: Track all ERC-20 token balances held by GravityAlpha's bridge addresses
- **Logic**: Monitor the Ethereum address `0x7983403dda368aa7d67145a9b81c5c517f364c42` to identify all tokens held by this bridging contract. The system tracks balance changes over time by processing `Transfer` events and other relevant blockchain transactions that affect token holdings. Each token's balance is calculated by tracking inflows and outflows to the bridge address, accounting for different ERC-20 token decimal configurations
- **Key fields**: The `balance` field represents the token quantity held, `timestamp` for temporal tracking, and `chain` to identify the blockchain (Ethereum in this case)

### Component B: USD conversion and normalization  
- **Purpose**: Convert token balances to standardized USD values for aggregation
- **Logic**: Apply end-of-day price feeds to convert each token balance to USD equivalent. The system normalizes token amounts based on each token's decimal configuration (typically 18 decimals for most ERC-20 tokens) before applying price conversion. Prices are sourced from daily price feeds to ensure consistent valuation timing across all tokens
- **Key fields**: Convert raw `balance` amounts to USD-denominated values using `price` data and `decimals` normalization

### Component C: Business metadata enrichment
- **Purpose**: Add relevant business context and categorization to the portfolio data
- **Logic**: Assign business-relevant metadata including market sector classification as `blockchains_l2` to reflect GravityAlpha's focus on Layer 2 solutions, business segment as `blockchain` to categorize the protocol type, and chain identification as Ethereum. The `product_id` is set to null as this represents protocol-level bridge deposits rather than specific product holdings
- **Key fields**: `market_sector_id`, `business_segment_id`, `chain_id`, and `product_id` for business intelligence categorization

### Final aggregation
- **Combining components**: Sum all USD-converted token balances held by the bridge address to calculate total bridge deposits. The aggregation groups by timestamp, timestamp grain, chain, and business metadata fields to maintain proper dimensional structure
- **Currency conversion**: All token balances are converted to USD using end-of-day price feeds, ensuring consistent valuation timing across different tokens held in the bridge
- **Time aggregation**: Data is aggregated at daily intervals with a fill-forward strategy applied to handle missing data points, ensuring continuous time series representation
- **Final calculation**: The final `bridge_deposits` value represents the sum of all USD-valued token balances held by GravityAlpha's bridge address, filtered by chain data availability windows to ensure data quality and reliability
