# Pons V2 Graduated Pools Trading volume Methodology

## 1. Overview

Trading volume is defined as the total value of trades executed on Pons V2 Graduated Pools. Liquidity and trading activity of assets that have successfully graduated from the bonding curve phase into Uniswap V4 pools are reflected by this metric. Because trading fees are generated as a percentage of this volume, the protocol's fee-generation capacity and overall market demand are indicated by this metric. All volume is denominated in the respective quote assets and converted to USD.

## 2. Data sources

- **Blockchain events**: `PoolRegistered` events from `MemeHook` contracts and `Swap` events from `PoolManager` 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 asset identification

- **Purpose**: Identify graduated pools and their corresponding quote assets.
- **Logic**: `PoolRegistered` events from `MemeHook` contracts are parsed to map each graduated pool identifier to its memecoin address and quote asset address. The relative order of the quote asset address and the memecoin address is evaluated to determine if the quote asset is the first currency in the pair (currency0).
- **Key fields**: `poolId` (pool identifier), `memecoin` (memecoin address), `quoteToken` (quote asset address)

### Component B: Swap volume extraction

- **Purpose**: Extract the raw trading volume from Uniswap V4 swap events.
- **Logic**: `Swap` events from `PoolManager` contracts are filtered to include only those matching the registered pool identifiers of graduated pools. The raw trading volume is extracted as the absolute value of the swap amount. If the quote asset is determined to be currency0, the volume is extracted from `amount0`; otherwise, it is extracted from `amount1`.
- **Key fields**: `id` (pool identifier), `amount0` (amount of currency0), `amount1` (amount of currency1)

### Component C: Decimal normalization and USD conversion

- **Purpose**: Normalize raw volumes by decimal precision and convert them to USD.
- **Logic**: Raw trading volumes are normalized by the decimal precision of the respective quote asset, which is retrieved from asset metadata. For native ETH (represented by the zero address), a precision of 18 decimals is applied. The normalized volumes are then multiplied by end-of-day asset prices to calculate the USD-denominated trading volume. Daily values are aggregated using UTC day boundaries.
- **Key fields**: `timestamp` (timing), `trading_volume` (volume quantity), `token_address` (asset identification)

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.
