# Sorare Bridge deposits Methodology

## 1. Overview

The Sorare bridge deposits metric measures the total USD value of tokens held in Sorare's bridge deposit address on Ethereum. This metric tracks the amount of value that users have deposited to Sorare's bridge infrastructure, providing insight into the protocol's bridging activity and locked value. The calculation involves tracking token balances at a specific Ethereum address and converting them to USD values using end-of-day pricing.

## 2. Data sources

The calculation relies on several core blockchain and external data sources:
- **Ethereum transaction data**: Transaction records and traces to track token movements
- **ERC-20 Transfer events**: Parsed `Transfer` events from Ethereum to calculate token balance changes
- **Token metadata**: Token contract information including decimal places and symbols for proper normalization
- **End-of-day price feeds**: Token price data for USD conversion at daily intervals
- **Chain availability data**: Information about data completeness and reliability for filtering

## 3. Step-by-step calculation

### Component A: Portfolio balance calculation
- **Purpose**: Calculate the current token balances held at Sorare's bridge deposit address
- **Logic**: The system identifies Sorare's designated bridge address (`0xf5c9f957705bea56a7e806943f98f7777b995826`) on Ethereum and calculates token balances using the portfolio methodology. This involves processing all ERC-20 `Transfer` events involving this address, tracking inflows and outflows to determine current holdings for each token. The calculation accounts for different token decimal places and normalizes balances accordingly.
- **Key fields**: The `balance` field represents the quantity of each token held, the `timestamp` field marks the calculation point, and `chain` identifies Ethereum as the blockchain

### Component B: USD conversion and aggregation
- **Purpose**: Convert individual token balances to USD values and sum them for total bridge deposits
- **Logic**: Each token balance is converted to USD using end-of-day price feeds matched to the calculation timestamp. The system applies proper decimal corrections based on each token's metadata to ensure accurate value calculations. All USD-converted token balances at the bridge address are then summed to produce the total bridge deposit value.
- **Key fields**: The `bridge_deposits` field contains the final USD sum of all token values held at the address

### Component C: Business data enrichment
- **Purpose**: Add contextual business information to categorize the metric appropriately
- **Logic**: The system enriches the calculated values with business metadata, classifying this metric under the "blockchains_l2" market sector and "blockchain" business segment. The `product_id` is set to null as this represents a protocol-level metric rather than a specific product metric.
- **Key fields**: `market_sector_id` is set to "blockchains_l2", `business_segment_id` is set to "blockchain", and `product_id` remains null

### Final aggregation
- **Combining components**: The portfolio balances are aggregated by timestamp and chain, with all token values summed into a single `bridge_deposits` value
- **Currency conversion**: USD conversion occurs at the individual token level using end-of-day price feeds before aggregation
- **Time aggregation**: The metric maintains daily granularity with timestamp boundaries aligned to end-of-day pricing
- **Final calculation**: The final bridge deposits value represents the total USD equivalent of all ERC-20 tokens held at Sorare's bridge address at each point in time, with a fill-forward strategy applied to handle missing data points and chain availability filtering to ensure data quality
