# pump.fun Supply-side fees Methodology

## 1. Overview

Supply-side fees for pump.fun are measured as the portion of trading fees allocated to token creators. A significant change was introduced to this metric on May 13, 2025, when creator fee sharing was implemented on pump.fun. Prior to this date, all fees were allocated to the protocol (supply-side fees were 0). After this date, supply-side fees are calculated as the creator fees extracted from pump.fun trading events.

## 2. Data sources

- **Blockchain events**: `TradeEvent` events from `pumpfun_v1` programs, covering Solana
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Historical period (before May 13, 2025)
- **Purpose**: Used to establish that supply-side fees were zero during the initial pump.fun period
- **Logic**: For all dates before May 13, 2025, supply-side fees are explicitly set to 0. This reflects the original pump.fun fee structure where all trading fees (1% of each trade) were allocated to the protocol, with no creator fee sharing.
- **Key fields**: `fees_supply_side` set to 0, standard metadata fields (`timestamp`, `timestamp_grain`, `chain_id`, `product_id`)

### Component B: New period (May 13, 2025 onwards)
- **Purpose**: Used to calculate supply-side fees as creator fees from pump.fun's trading events
- **Logic**: Creator fee amounts are extracted from `TradeEvent` events from `pumpfun_v1` programs. The token address is determined from the quote mint field, defaulting to the SOL mint address if null or set to the default public key. Creator fee amounts are aggregated daily by summing all creator fee amounts for each day and token address.
- **Key fields**: `creator_fee_amount` from trading events, `token_address` representing the quote asset, `timestamp` truncated to day level

### Component C: USD conversion

- **Purpose**: Used to standardize creator fee amounts in USD currency
- **Logic**: End-of-day asset to USD conversion rates are applied to the creator fee amounts. Standard decimal correction is applied to normalize the raw amounts based on token decimal precision.
- **Key fields**: `fees_supply_side` in USD, maintaining all original metadata

### Component D: Final aggregation

- **Purpose**: Used to combine historical and new fee periods into a single time series
- **Logic**: The historical zero fees and the new creator fees are combined. Daily aggregation is performed with timestamp truncation to day boundaries. Any remaining data gaps are filled with zeros.
- **Key fields**: `fees_supply_side` (final aggregated supply-side fees in USD)
