# re.al Bridge deposits Methodology

## 1. Overview

Real bridge deposits measures the total USD value of tokens deposited in Real protocol's bridging infrastructure. This metric quantifies the capital locked in Real's bridge contracts, providing insight into the protocol's bridging activity and user adoption of cross-chain functionality. The calculation tracks token balances held at specific bridge contract addresses and converts them to USD values.

## 2. Data sources

The calculation relies on several raw data sources:
- **Ethereum token transfers**: Parsed `Transfer` events from ERC-20 token contracts to track token movements into and out of bridge addresses
- **Token metadata**: Contract information including token decimals, symbols, and addresses for proper balance calculations  
- **End-of-day price feeds**: Token price data for USD conversion of bridge deposits
- **Ethereum transaction data**: Transaction records and traces to validate transfer events and ensure data completeness
- **Chain availability data**: Metadata indicating which blockchain networks meet data quality requirements for inclusion

## 3. Step-by-step calculation

### Component A: Bridge address identification
- **Purpose**: Identifies the specific Ethereum addresses that serve as Real protocol's bridge deposit contracts
- **Logic**: The calculation targets two predetermined Ethereum addresses (`0xfc89b875970122e24c6c5add4dea139443943ea7` and `0x679d4c1cc6855c57726bea1784f578315d6431f6`) that function as Real's bridging infrastructure. These addresses represent the smart contracts where users deposit tokens for cross-chain bridging operations.
- **Key fields**: Bridge contract addresses are used as the foundation for all subsequent balance calculations

### Component B: Portfolio balance calculation  
- **Purpose**: Determines the current token balances held at each bridge address for all supported tokens
- **Logic**: Token transfer events are processed to track the flow of tokens into and out of the identified bridge addresses. For each token contract, inbound transfers increase the bridge balance while outbound transfers decrease it. The calculation maintains running balances over time by processing transfers chronologically. Only valid ERC-20 transfer events are included, with proper decimal adjustment based on each token's metadata.
- **Key fields**: Token balances are calculated as net transfers (inbound minus outbound) with proper decimal normalization using each token's `decimals` field

### Component C: Business categorization
- **Purpose**: Adds business context and metadata for proper metric classification
- **Logic**: Each calculated balance is tagged with business-relevant identifiers. Bridge deposits are categorized under the `blockchains_l2` market sector since Real operates as a Layer 2 solution. The business segment is set to `blockchain` to indicate this represents core blockchain infrastructure metrics. No specific product categorization is applied as bridge deposits represent protocol-level functionality.
- **Key fields**: `market_sector_id` set to "blockchains_l2", `business_segment_id` set to "blockchain", `product_id` left null

### Final aggregation
- **Combining components**: Token balances across all bridge addresses are summed together to create a single aggregate bridge deposits value. Multiple tokens held at the same address are combined, and balances across different bridge addresses are also aggregated.
- **Currency conversion**: Each token balance is converted to USD using end-of-day token prices. The conversion applies the price to the properly decimalized token amount to get USD values.
- **Time aggregation**: Bridge deposit values are calculated as point-in-time snapshots, typically aggregated to daily granularity. The finalization process handles time boundaries and ensures consistent timestamp alignment.
- **Final calculation**: The final bridge deposits metric represents the total USD value of all tokens currently held across Real protocol's bridge contract addresses, providing a measure of capital locked in the bridging infrastructure
