# Mint Blockchain Bridge deposits Methodology

## 1. Overview

Bridge deposits measures the total USD value of assets held in Mint blockchain's designated bridge contracts on Ethereum. This metric tracks the cumulative value locked in bridging infrastructure, representing user funds that have been deposited for cross-chain transfers to and from Mint blockchain. The calculation monitors specific Ethereum addresses that serve as bridge endpoints and aggregates all token balances held in these contracts.

## 2. Data sources

- **Ethereum blockchain events**: Parsed `Transfer` events from Ethereum to track token movements into and out of bridge addresses
- **Token balance data**: Current and historical token balance snapshots for specific bridge contract addresses on Ethereum
- **End-of-day price feeds**: USD price data for all tokens held in bridge contracts to enable currency conversion
- **Token metadata**: Contract information and decimal precision data for proper balance calculations
- **Chain availability data**: Status information to filter periods with incomplete or unreliable data

## 3. Step-by-step calculation

### Component A: Bridge address portfolio tracking
- **Purpose**: Calculates token balances held in designated bridge contract addresses on Ethereum
- **Logic**: Monitors two specific Ethereum addresses (`0x2b3f201543adf73160ba42e1a5b7750024f30420` and `0x59625d1fe0eeb8114a4d13c863978f39b3471781`) that serve as Mint blockchain's bridge endpoints. Tracks all token balances held in these addresses over time by processing Ethereum `Transfer` events and calculating net inflows and outflows. Handles multiple token types and maintains historical balance snapshots with proper decimal adjustments for each token contract.
- **Key fields**: `timestamp` for time series tracking, `chain` identifier for Ethereum, `balance` representing token amounts held in bridge addresses

### Component B: Business categorization and aggregation  
- **Purpose**: Applies business context and aggregates balances across all bridge addresses and tokens
- **Logic**: Groups balance data by timestamp and chain, applying standardized business categorization with `market_sector_id` set to 'blockchains_l2' and `business_segment_id` set to 'blockchain'. Sums all token balances across the bridge addresses to calculate total bridge deposits value. Sets `product_id` to null as this represents aggregate bridge activity rather than specific products.
- **Key fields**: `bridge_deposits` as the aggregated USD value, business classification fields for reporting categorization

### Final aggregation
- **Combining components**: Sums all token balances held across both designated bridge addresses to create a single bridge deposits value per time period
- **Currency conversion**: Converts all token balances to USD using end-of-day price feeds, applying proper decimal adjustments based on token contract specifications
- **Time aggregation**: Maintains daily time series with timestamp grain standardization and applies fill-forward strategy to interpolate missing values during periods with no bridge activity
- **Final calculation**: The final bridge deposits metric represents the total USD value of all tokens held in Mint blockchain's Ethereum bridge contracts at each point in time, filtered for periods with reliable chain data availability
