Liquidity providers deposit funds into Dopex and receive premiums from options traders (supply-side fees).

Dopex is a non-custodial exchange for options contracts built on Arbitrum. Dopex was founded by the pseudonymous TzTok-Chad, and was launched in 2021.

DPX tokenholders own and govern the protocol. They currently take a cut of the total trading fees paid by traders (revenue). Dopex’s investors include Tetranode, DefiGod, Orca Traders, Pattern Research, etc.

# Dopex Supply-side fees Methodology

## 1. Overview

Fees supply side measures the daily premium amounts from Dopex options trading that are distributed to liquidity providers. This metric captures revenue earned by users who provide liquidity to Dopex's options protocols, including both SSOV (Single Staking Option Vaults) v1 and CLAMM (Concentrated Liquidity Automated Market Maker) v2 products. The calculation aggregates premium payments from options purchases across multiple underlying assets and converts them to USD for standardized reporting.

## 2. Data sources

The calculation relies on several data sources:
- **Arbitrum blockchain event logs**: Parsed `Purchase` events from Dopex SSOV v1 contracts and `LogMintOption` events from Dopex CLAMM v2 option market contracts
- **Options trading events**: Events from 17 different SSOV v1 contracts covering various underlying assets (ARB, DPX, RDPX, ETH, stETH, CRV, GMX, GOHM) and 3 CLAMM v2 option market contracts (ARB, WETH, WBTC)
- **End-of-day price feeds**: Token price data for USD conversion of premium amounts
- **Token metadata**: Decimal precision information for accurate amount calculations

## 3. Step-by-step calculation

### Component A: SSOV v1 premium extraction
- **Purpose**: Extract premium amounts from Dopex Single Staking Option Vaults v1 trading activity
- **Logic**: Process `Purchase` events from 17 different SSOV v1 contracts on Arbitrum, each representing options for specific underlying assets. Extract the `premium` field from each event, which represents the amount paid by option buyers to liquidity providers. Map each contract to its corresponding underlying token address. Classify all events with product identifier 'dopexssovv1' and categorize under derivatives market sector with options business segment.
- **Key fields**: `premium` (premium amount paid to LPs), `token_address` (underlying asset), `block_timestamp` (event timing), `transaction_hash` and `log_index` (event identification)

### Component B: CLAMM v2 premium extraction  
- **Purpose**: Extract premium amounts from Dopex CLAMM v2 options trading activity
- **Logic**: Process `LogMintOption` events from 3 CLAMM v2 option market contracts on Arbitrum (ARB, WETH, WBTC). Extract the `premiumAmount` field representing premiums paid to liquidity providers. Dynamically assign token addresses based on the `isCall` flag - use the call token address when the option is a call option, otherwise use the put token address (USDC). Classify all events with product identifier 'dopexclammv2' under derivatives market sector.
- **Key fields**: `premiumAmount` (premium paid to LPs), `isCall` (option type flag), `token_address` (dynamically assigned based on option type), `block_timestamp` (event timing)

### Final aggregation
- **Combining components**: Union the premium amounts from both SSOV v1 and CLAMM v2 sources, treating both as supply-side fees since they represent payments to liquidity providers
- **Currency conversion**: Convert all premium amounts to USD using end-of-day price feeds, applying token-specific decimal corrections to ensure accurate value calculations
- **Time aggregation**: Truncate all timestamps to daily boundaries and group by day, chain, market sector, business segment, product, and token address
- **Final calculation**: Sum all premium amounts for each day and token combination after USD conversion and decimal correction, applying a zero-fill strategy to maintain continuous time series data for consistent reporting
