# Ancient8 Bridge deposits Methodology

## 1. Overview

Ancient8 bridge deposits measures the total USD value of tokens held in Ancient8's bridging infrastructure on Ethereum. This metric tracks the amount of value that users have deposited into Ancient8's bridge contracts, representing the total assets under management in their cross-chain bridging system. The metric helps assess the usage and trust in Ancient8's bridging solution by measuring the cumulative value locked in their bridge contracts.

## 2. Data sources

- **Ethereum token transfer events**: Parsed `Transfer` events from ERC20 and native token contracts to track token movements into and out of the bridge address
- **Ethereum transaction traces**: Transaction execution traces to capture all balance-affecting activities including internal transfers and contract interactions
- **Token metadata**: Token contract information including decimal precision and token symbols for proper balance calculations  
- **End-of-day token price feeds**: Daily USD price data for all tokens to enable consistent currency conversion
- **Chain availability data**: Information about data availability and quality periods for filtering unreliable data periods

## 3. Step-by-step calculation

### Component A: Portfolio balance tracking
- **Purpose**: Calculates the current token balances held in Ancient8's bridge contract address
- **Logic**: The system tracks all token movements for the bridge contract address `0x639f2aece398aa76b07e59ef6abe2cfe32bacb68` on Ethereum. It processes token transfer events to identify when tokens are deposited into or withdrawn from the bridge contract. The system maintains running balances for each token type by processing chronological transfer events and applying decimal corrections based on each token's contract specifications. Transaction traces are also analyzed to capture any balance changes that might not appear in standard transfer events.
- **Key fields**: Bridge contract address `0x639f2aece398aa76b07e59ef6abe2cfe32bacb68`, token contract addresses, transfer amounts with decimal corrections, timestamps for chronological processing

### Component B: Business data classification  
- **Purpose**: Adds Ancient8-specific business context and aggregates balances across all tokens
- **Logic**: The individual token balances are classified with Ancient8's business metadata. Each record is labeled with `chain_id` to identify Ethereum as the source chain, `market_sector_id` as 'blockchains_l2' to categorize Ancient8 as a Layer 2 blockchain solution, and `business_segment_id` as 'blockchain' to identify the business type. The system then aggregates all token balances held in the bridge contract into a single total value for each timestamp and time grain combination.
- **Key fields**: Timestamp and time grain for temporal aggregation, chain identifier, market sector and business segment classifications, aggregated `bridge_deposits` value

### Final aggregation
- **Combining components**: The portfolio balances are summed across all token types to create a single bridge deposits value representing the total value held in Ancient8's bridge infrastructure
- **Currency conversion**: All token balances are converted to USD using end-of-day price feeds, ensuring consistent valuation timing across different tokens
- **Time aggregation**: The metric supports multiple time grains (daily, weekly, monthly) with data points calculated for each relevant timestamp boundary
- **Final calculation**: The final bridge deposits value represents the sum of all token balances (in USD) held in Ancient8's bridge contract address at each point in time, with forward-fill applied to handle data gaps and chain availability filtering to ensure data quality
