# Pons V2 Graduated Pools Supply-side fees Methodology

## 1. Overview

Supply-side fees is measured as the share of fees that goes to the service providers. For Pons V2 Graduated Pools, this metric is represented by the cumulative value of creator fees and buyback allocations accumulated within graduated Uniswap V4 pools. These fees are collected in the pool's designated quote asset, normalized by decimal precision, and converted to USD.

## 2. Data sources

- **Blockchain events**: `PoolRegistered` and `PoolFeesSwept` events from `MemeHook` contracts, covering Robinhood Chain
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Pons V2 Graduated Pools pool registration

- **Purpose**: To identify active graduated pools and their associated quote assets.
- **Logic**: `PoolRegistered` events from `MemeHook` contracts are parsed to map each graduated pool ID to its corresponding quote asset address.
- **Key fields**: `poolId` and `quoteToken`

### Component B: Pons V2 Graduated Pools fee extraction

- **Purpose**: To extract the raw fee components distributed to supply-side participants.
- **Logic**: `PoolFeesSwept` events from `MemeHook` contracts are parsed and joined with the registered pools. The creator fee amount and buyback fee amount are extracted for each sweep event. These two components are summed to represent the total raw supply-side fee allocation in the quote asset.
- **Key fields**: `poolId`, `creatorAmount`, and `buybackAmount`

### Component C: Normalization and USD conversion

- **Purpose**: To normalize fee amounts by decimal precision and convert them to USD.
- **Logic**: Raw fee amounts are joined with asset metadata to determine decimal precision. If the quote asset is the native asset, a default precision of 18 decimals is applied; otherwise, the asset's specific decimal value is used. Normalized fee amounts are multiplied by end-of-day asset prices to calculate the USD value. Daily aggregation is performed using UTC day boundaries.
- **Key fields**: `timestamp`, `token_address`, and `fees_supply_side`

Pons charges a 0.0005 ETH launch fee and a fee on every trade. Trade fees are shared between the protocol, the token creator and optional meme token buybacks.

Pons is a token launchpad on Robinhood Chain. Version 2 launches sell tokens on a bonding curve and graduate them into locked Uniswap v4 pools, while version 1 launches trade directly in Uniswap v3 pools.
