# RARI Chain Bridge deposits Methodology

## 1. Overview

The RARI Chain bridge deposits metric measures the total USD value of assets held in RARI Chain's bridge deposit contracts on Arbitrum. This metric tracks the cumulative value of tokens that users have deposited into bridge contracts for potential transfer to RARI Chain, providing insight into the capital locked in the bridging infrastructure. The calculation focuses on monitoring token balances at specific bridge contract addresses and converting these balances to USD values using end-of-day pricing data.

## 2. Data sources

- **Arbitrum blockchain events**: Parsed `Transfer` events for ERC-20 tokens and native ETH transfers involving the bridge contract addresses
- **Transaction data**: Arbitrum transaction logs and traces to track token movements into and out of bridge contracts
- **External data**: End-of-day token price feeds for USD conversion and token metadata including decimal precision configurations
- **Infrastructure data**: Chain availability status data to ensure data quality and operational transparency

## 3. Step-by-step calculation

### Component A: Portfolio balance calculation
- **Purpose**: Calculates the current token balances held across RARI Chain's bridge deposit contracts
- **Logic**: Processes all token transfer events involving two specific Arbitrum addresses (`0x46406c88285ad9be2fb23d9ad96cb578d824cab6` and `0x255f80ef2f09fce0944fabb292b8510f01316cf0`) that serve as bridge deposit contracts. For each address, the system tracks incoming transfers (deposits) and outgoing transfers (withdrawals or bridge completions) for all token types including both ERC-20 tokens and native ETH. The net balance is calculated as total inflows minus total outflows over time, maintaining running balances for each token at each address
- **Key fields**: Tracks `balance` amounts for each token type, `timestamp` for time-series data, and `chain` identifier for Arbitrum

### Component B: Business data aggregation
- **Purpose**: Combines balances across all bridge addresses and applies business categorization
- **Logic**: Aggregates the individual token balances across both bridge contract addresses to create a single total balance figure. Assigns business metadata including `market_sector_id` as 'blockchains_l2' to categorize this as a layer 2 blockchain metric, `business_segment_id` as 'blockchain' for the infrastructure segment, and sets `product_id` to null as this represents overall bridge infrastructure rather than a specific product
- **Key fields**: Creates aggregated `bridge_deposits` value and assigns categorical business identifiers for reporting structure

### Final aggregation
- **Combining components**: Sums all token balances across both bridge contract addresses to create a single bridge deposits value per timestamp
- **Currency conversion**: Converts all token balances to USD using end-of-day price feeds, accounting for proper decimal precision based on token metadata
- **Time aggregation**: Maintains time-series data with forward-filling strategy to ensure continuity in reporting even when no new transactions occur
- **Final calculation**: The final metric represents the total USD value of all tokens currently held in RARI Chain's bridge deposit contracts on Arbitrum, calculated as the sum of USD-converted balances across all token types and bridge addresses, filtered by chain availability status to ensure data quality
