# Pons V2 Graduated Pools Fees Methodology

## 1. Overview

Fees measure the total value paid by users during swap activities on graduated liquidity pools within Pons V2 Graduated Pools. This economic value is generated by the protocol's graduated pools and is distributed among various stakeholders, including the protocol treasury, buyback mechanisms, and creators. Collected fees are denominated in the respective quote assets of the pools and are normalized and converted to USD. This metric is utilized to assess the financial performance and protocol monetization of Pons V2 Graduated Pools.

## 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 registration and mapping

- **Purpose**: Map graduated pools to their respective memecoin and quote assets
- **Logic**: `PoolRegistered` events from `MemeHook` contracts are parsed to identify graduated pools. For each pool, the pool ID, memecoin address, and quote asset address are extracted. The quote asset is identified as either the native asset or a specific ERC-20 asset.
- **Key fields**: `pool_id` (pool identification), `memecoin` (memecoin address), `token_address` (quote asset address)

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

- **Purpose**: Capture and aggregate fees collected from graduated pools
- **Logic**: `PoolFeesSwept` events from `MemeHook` contracts are parsed to extract fee amounts. These fees are categorized into protocol fees, buyback fees, and creator fees. The extracted amounts are aggregated by day, product ID, and quote asset address.
- **Key fields**: `pool_id` (pool identification), `protocol_amount` (protocol fee quantity), `buyback_amount` (buyback fee quantity), `creator_amount` (creator fee quantity)

### Component C: Decimal normalization and USD conversion

- **Purpose**: Normalize fee amounts by decimal precision and convert them to USD
- **Logic**: Aggregated fee amounts are joined with asset metadata to determine the decimal precision of each quote asset. For native assets, a default precision of 18 decimals is applied. Normalized fee components (protocol, buyback, and creator fees) are summed to calculate total fees. These total fees are then multiplied by end-of-day price feeds to calculate the final USD value. Daily granularity is maintained using UTC day boundaries.
- **Key fields**: `timestamp` (timing), `decimals` (asset precision), `price_usd` (asset price)

Exchanges (DEX)

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.
