# Boba Network Bridge deposits Methodology

## 1. Overview

Bridge deposits measures the total USD value of tokens held in Boba Network's bridge contracts on Ethereum. This metric tracks the aggregate value of assets that have been deposited into the bridge for transfer to or storage on Boba Network's Layer 2 blockchain. The calculation monitors specific bridge contract addresses and aggregates the USD value of all tokens held across these contracts.

## 2. Data sources

The metric relies on the following data sources:
- **Ethereum token transfer events**: Parsed ERC-20 `Transfer` events on Ethereum mainnet to track token movements into and out of bridge contracts
- **Ethereum transaction traces**: Native ETH transfer data from Ethereum transaction execution traces 
- **End-of-day price feeds**: Token price data for USD conversion of all tracked assets
- **Token metadata**: Token configuration including decimal places, symbols, and contract addresses
- **Chain availability data**: Configuration defining valid time ranges for metric reporting

## 3. Step-by-step calculation

### Component A: Portfolio balance tracking
- **Purpose**: Track token balances held across Boba Network's bridge contract addresses on Ethereum
- **Logic**: The system monitors two specific Ethereum addresses (`0xdc1664458d2f0b6090bea60a8793a4e66c2f361a14` and `0x1a26ef6575b7bbb864d984d9255c069f6c361a14`) which serve as Boba Network's bridge contracts. For each address, the system processes all historical token transfer events to calculate running balances for every token type. Inbound transfers increase the balance while outbound transfers decrease it. The system also tracks native ETH holdings through transaction trace analysis.
- **Key fields**: Address balances are tracked per `token_address`, `account_address`, and `timestamp`, with running `balance` calculations maintained over time

### Component B: USD conversion and aggregation  
- **Purpose**: Convert all token balances to USD and aggregate across bridge addresses
- **Logic**: Each token balance is converted to USD using end-of-day price feeds, with proper decimal adjustment based on token specifications. All USD-converted balances are then summed across both bridge contract addresses to calculate the total bridge deposits value.
- **Key fields**: The final `bridge_deposits` value represents the sum of all USD-converted token balances across the bridge contracts

### Final aggregation
- **Combining components**: Portfolio balances from both bridge addresses are aggregated by summing USD-converted values across all tokens and addresses
- **Currency conversion**: USD conversion is performed using end-of-day price feeds with appropriate decimal adjustments for each token
- **Time aggregation**: Metrics are calculated with daily granularity based on timestamp boundaries
- **Final calculation**: The bridge deposits metric equals the total USD value of all tokens held across Boba Network's bridge contract addresses on Ethereum, including both ERC-20 tokens and native ETH. The calculation applies business metadata including market sector classification as `blockchains_l2` and business segment as `blockchain`, with a fill-forward strategy applied to maintain data continuity across time periods.
