WINR Protocol

# WINR Protocol Bridge deposits Methodology

## 1. Overview

Bridge deposits represents the total USD value of tokens held in WINR's bridging infrastructure on Arbitrum. This metric measures the capital locked in WINR's cross-chain bridging system, providing insight into user deposits that are being bridged between networks for the gaming protocol. The calculation tracks token balances across seven specific Arbitrum addresses that serve as bridge contracts and infrastructure components.

## 2. Data sources

- **Arbitrum blockchain events**: Parsed `Transfer` events from ERC-20 token contracts to track token movements into and out of bridge addresses
- **Arbitrum transaction traces**: Transaction-level data showing token transfers and contract interactions with bridge addresses
- **Token metadata**: Contract information including token decimals, symbols, and contract addresses for proper balance calculations
- **End-of-day price feeds**: Daily USD price data for all tokens held in bridge addresses
- **Daily balance snapshots**: Historical balance data to support fill-forward methodology for missing data points

## 3. Step-by-step calculation

### Component A: Address identification and monitoring
- **Purpose**: Defines the specific Arbitrum addresses that constitute WINR's bridging infrastructure
- **Logic**: Seven hardcoded Arbitrum addresses are identified as the complete set of bridge-related contracts: `0xf3f01622ac969156760c32190995f9dc5b3eb7fa`, `0x8e83aed64a0ad5d7d3a57b6172f14fca5bfade56`, `0x6adfba9e45b5c1685007fe48a784e971e412f839`, `0x8b961a67f49bc6334cba09dbd70a2f14fc8226a1`, `0x3222f0f281f1630c50f86ffaa29a29a06559eca8`, `0x0aE2F220cE9698b1c9853f7288aC882150291dca`, and `0x023d27390aed70aa39823a1e1e06a0b075400214`. These addresses represent the core bridging contracts and infrastructure components for WINR's cross-chain operations
- **Key fields**: `account_addresses` containing the seven monitored contract addresses on Arbitrum

### Component B: Portfolio balance calculation
- **Purpose**: Calculates the token balances held in each bridge address using the portfolio macro
- **Logic**: For each monitored address, the system processes all historical `Transfer` events and transaction traces to determine token holdings. The calculation tracks incoming transfers (deposits), outgoing transfers (withdrawals), and maintains running balances for each token type held by each address. Token decimal metadata is applied to convert raw blockchain amounts to proper token units. This creates a comprehensive view of all tokens held across the seven bridge addresses
- **Key fields**: `timestamp` for daily snapshots, `chain` identifying Arbitrum, `balance` representing token amounts in proper decimal format

### Component C: USD conversion and aggregation  
- **Purpose**: Converts token balances to USD values and aggregates across all bridge addresses
- **Logic**: Each token balance is converted to USD using end-of-day price feeds matched by token contract address and date. The conversion process handles multiple tokens per address and multiple addresses per day. All USD values are then summed across addresses to calculate the total bridge deposits value. Missing price data is handled through the portfolio macro's built-in logic
- **Key fields**: `balance` converted to USD amounts, aggregated using sum function

### Component D: Business metadata application
- **Purpose**: Adds business context and categorization for reporting purposes
- **Logic**: Standard business dimensions are applied to categorize the metric within Token Terminal's framework. The chain is identified as Arbitrum, the market sector is set to `blockchains_l3` reflecting WINR's layer-3 gaming focus, and the business segment is classified as `blockchain`. No specific product categorization is applied (set to null)
- **Key fields**: `chain_id` set to Arbitrum, `market_sector_id` as `blockchains_l3`, `business_segment_id` as `blockchain`, `product_id` as null

### Final aggregation
- **Combining components**: All bridge address balances are summed by day to create a single daily bridge deposits value representing total capital locked in WINR's bridging infrastructure
- **Currency conversion**: USD conversion uses end-of-day price feeds matched by token contract and timestamp, ensuring consistent daily valuations
- **Time aggregation**: Daily boundary logic groups data by timestamp grain, creating one record per day
- **Final calculation**: The final `bridge_deposits` value equals the sum of all USD-converted token balances across the seven monitored Arbitrum addresses, processed through the finalization macro with fill-forward strategy to handle missing data points and filtered by chain availability constraints
