Liquidity providers deposit funds into Deri Protocol and receive trading fees from traders (supply-side fees).

Deri Protocol is a non-custodial exchange for perpetual contracts built on BNB Chain and Arbitrum. Deri Protocol was founded by an anonymous team and launched in 2021.

DERI token holders own and govern the protocol. They currently take a cut of the total trading fees paid by traders (revenue).

# Deri Protocol Bridge deposits Methodology

## 1. Overview

Bridge deposits for Deri Protocol measures the total USD value of tokens held in designated bridging addresses on Arbitrum. This metric tracks funds that users have deposited into bridge contracts, representing capital that is available for cross-chain transfers or protocol operations. The calculation monitors specific bridge addresses and aggregates the daily USD value of all tokens held in those addresses.

## 2. Data sources

The calculation relies on several key data sources:
- **Token transfer events**: Parsed Arbitrum `Transfer` events for all ERC-20 tokens to track balance changes in bridge addresses
- **Transaction data**: Arbitrum transaction traces to provide context for transfer events
- **Price feeds**: End-of-day token price feeds for USD conversion of token balances
- **Token metadata**: Token registry data containing decimal precision and token identifiers
- **Chain availability data**: Configuration data specifying valid time periods for Arbitrum data

## 3. Step-by-step calculation

### Component A: Portfolio balance tracking
- **Purpose**: Calculate daily token balances for the designated bridge address on Arbitrum
- **Logic**: The system monitors the specific bridge address `0xd4fe46d2533e7d03382ac6cacf0547f336e59dc0` on Arbitrum. It processes all token transfer events where this address is either the sender or recipient to track balance changes over time. For each token, it calculates the net balance by adding incoming transfers and subtracting outgoing transfers. The balances are calculated daily, creating snapshots of token holdings at the end of each day.
- **Key fields**: The calculation tracks `balance` amounts for each token, `timestamp` for daily snapshots, and `chain` identifier for Arbitrum

### Component B: Business data enhancement
- **Purpose**: Add business context and aggregate token balances into a single metric
- **Logic**: The daily token balances are enhanced with business metadata to categorize the metric appropriately. The system assigns `chain_id` as the chain identifier, sets `market_sector_id` to 'blockchains_l2' to indicate this is Layer 2 blockchain activity, and sets `business_segment_id` to 'blockchain' for the business category. The `product_id` is set to null as this represents general bridge activity rather than a specific product. All token balances for the bridge address are summed together to create a single aggregate `bridge_deposits` value for each day.
- **Key fields**: Key business fields include `market_sector_id`, `business_segment_id`, `product_id`, and the aggregated `bridge_deposits` amount

### Final aggregation
- **Combining components**: The enhanced portfolio data flows through the finalize metric process, which standardizes the output format and applies data quality measures
- **Currency conversion**: All token balances are converted to USD using end-of-day price feeds, with proper decimal adjustment based on token metadata
- **Time aggregation**: Data is aggregated on daily boundaries using the `timestamp_grain` field to ensure consistent daily snapshots
- **Final calculation**: The final bridge deposits metric represents the total USD value of all tokens held in the designated Deri Protocol bridge address on Arbitrum, with fill-forward strategy applied to handle any missing daily values and chain availability filters ensuring only reliable data periods are included
