# DEX Screener Fees Methodology

## 1. Overview

DexScreener fees represent the total daily fee revenue collected by DexScreener, a popular decentralized exchange aggregator and analytics platform on Solana. The metric captures fees paid to DexScreener through both native SOL transfers and SPL token transfers to their designated fee collector accounts. This provides insight into DexScreener's revenue generation and platform usage.

The calculation aggregates all transfers to DexScreener's fee collector accounts, excluding self-transfers, and converts the amounts to USD for standardized reporting.

## 2. Data sources

- **Solana native transfers**: All native SOL transfer events on the Solana blockchain, specifically transfers directed to recipient addresses
- **Solana SPL token transfers**: All SPL token transfer events on Solana, specifically transfers where the recipient owner matches target addresses  
- **End-of-day token price feeds**: Daily closing prices for SOL and SPL tokens used for USD conversion
- **Token metadata**: Token decimal information required for proper amount normalization

## 3. Step-by-step calculation

### Component A: SOL native fee collection
- **Purpose**: Captures fees paid to DexScreener in native SOL tokens
- **Logic**: Extracts all native SOL transfers directed to DexScreener's fee collector accounts (`23vEM5NAmK68uBHFM52nfNtZn7CgpHDSmAGWebsjg5ft` and `AJENSD55ZJBwipZnEf7UzW2pjxex1cV2jSKPz7aMwJo5`). Excludes transfers where the transaction signer is one of these fee accounts themselves, preventing double-counting of internal transfers. Sets `product_id` to null and standardizes the `token_address` to SOL's canonical address (`So11111111111111111111111111111111111111112`)
- **Key fields**: `block_timestamp` for timing, `transaction_id` for deduplication, `transaction_signer` for filtering, `amount` for fee value

### Component B: SPL token fee collection  
- **Purpose**: Captures fees paid to DexScreener in various SPL tokens
- **Logic**: Extracts SPL token transfers where the recipient owner address matches DexScreener's fee collector accounts. Applies the same exclusion logic to prevent self-transfers from being counted as fees. Preserves the original `token_address` to track which specific tokens were used for fee payments. Converts `amount` to proper numeric type for calculations
- **Key fields**: `block_timestamp` for timing, `token_address` for token identification, `transaction_signer` for filtering, `amount` for fee value

### Component C: Daily aggregation
- **Purpose**: Combines SOL and SPL fee data into daily totals by token
- **Logic**: Unions the SOL and SPL fee streams, then groups by day (using timestamp truncation), chain identifier, `product_id`, and `token_address`. Sums the `amount` field to get total daily fees for each token type. This creates a unified view of all fee collection regardless of token type
- **Key fields**: `timestamp` (daily), `chain_id` (always 'solana'), `token_address`, aggregated `fees` amount

### Final aggregation
- **Combining components**: The two fee streams (SOL and SPL) are combined through a UNION ALL operation, then aggregated by day and token type to create comprehensive daily fee totals
- **Currency conversion**: Uses the standard `convert_to_usd_and_correct_decimals` macro to convert all token amounts to USD using end-of-day price feeds and apply proper decimal corrections based on each token's decimal configuration
- **Time aggregation**: Daily boundaries are established through timestamp truncation to day level, ensuring consistent 24-hour periods for fee measurement
- **Final calculation**: The `finalize_metric_fees` macro applies standard schema formatting, validates data integrity, and implements a zero-fill strategy for any missing days to ensure continuous time series data. Chain availability filters are applied to respect data availability constraints.
