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 Fees Methodology

## 1. Overview

This metric calculates the total trading fees generated by Deri Protocol, a decentralized derivatives trading platform. The calculation aggregates fees paid by traders across perpetual futures contracts on Arbitrum and BSC chains. Fees are collected in either USD-denominated stablecoins for some markets or in DLT (Deri Protocol's native token) for others, requiring different processing approaches to standardize all fees into USD values for final reporting.

## 2. Data sources

The methodology relies on several key data sources:

- **Blockchain events**: Parsed Deri Protocol v3 `SymbolManager_Trade_event` and `Router_ExecuteTrade_event` logs from Arbitrum and BSC chains
- **Price data**: End-of-day price feeds for the DERI token from Ethereum mainnet to convert DLT-denominated fees to USD
- **Token metadata**: Manual symbol mappings for Deri Protocol trading pairs that supplement contract event data
- **Market configuration**: Hardcoded market contract addresses to distinguish between USD-denominated and DLT-denominated fee collection

## 3. Step-by-step calculation

### Component A: Raw trading fee extraction
- **Purpose**: Extracts base trading fee data from Deri Protocol smart contract events
- **Logic**: Processes `SymbolManager_Trade_event` logs from Deri Protocol v3 contracts on Arbitrum and BSC chains. The `tradeFee` field contains the fee amount in 18-decimal format. Negative fee values are filtered out and set to zero to handle edge cases. Fee amounts are converted from 18 decimals to standard decimal format. Events are joined with corresponding `Router_ExecuteTrade_event` logs using transaction hash to retrieve the `symbolName` field, which identifies the specific trading pair
- **Key fields**: `tradeFee` (fee amount in 18 decimals), `symbolId` (numeric identifier for trading pair), `symbolName` (human-readable trading pair name), `account_address` (market contract receiving fees)

### Component B: Symbol name resolution
- **Purpose**: Maps symbol IDs to human-readable trading pair names for proper categorization
- **Logic**: Creates two mapping sources - one from contract events and one from manual configurations. The contract-based mapping extracts distinct `symbolId` and `symbolName` pairs from joined Trade and ExecuteTrade events. The manual mapping provides hardcoded symbol names for specific symbol IDs that aren't consistently captured in ExecuteTrade events. This dual approach ensures comprehensive symbol coverage across all Deri Protocol markets
- **Key fields**: `symbol_id` (numeric identifier), `symbol_name` and `token_symbol` (trading pair names), `chain` (blockchain network)

### Component C: Currency-specific fee processing
- **Purpose**: Handles different fee denomination types (USD vs DLT) with appropriate currency conversion
- **Logic**: Separates markets into two categories based on account addresses. DLT-denominated markets (account address `0x8bb7ec8fb31dd6d33d9b71c1bd407f883cac7a91`) require currency conversion - fee amounts are multiplied by end-of-day DERI token prices from Ethereum mainnet to convert to USD values. USD-denominated markets (account addresses `0x543a9fa25ba9a16612274dd707ac4462ed6988fa`, `0x28ed1dbdb9bc5b7fe67c27c1d767db42ae6f61f7`, `0x741c8e810cd1c7bab6565e850b775fc33c15c084`) use fee amounts directly as they're already in USD terms
- **Key fields**: `fee_amount` (base fee from events), `price_usd` (DERI token price), `amount` (final USD fee value), `account_address` (market contract identifier)

### Final aggregation
- **Combining components**: DLT-denominated and USD-denominated fee calculations are combined using a union operation to create a single dataset containing all trading fees across both market types
- **Currency conversion**: DLT fees are converted to USD using end-of-day DERI token prices from Ethereum mainnet, matched by date. USD fees require no conversion
- **Time aggregation**: All fees are aggregated to daily boundaries using timestamp truncation to day level. The `day` grain is applied consistently across all records
- **Final calculation**: The metric represents the sum of all trading fees paid by users across Deri Protocol's perpetual futures markets, standardized to USD values and aggregated daily. Missing days are filled with zero values to ensure continuous time series data. Chain availability filters are applied to respect data availability windows for each blockchain network
