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.

# Pons Trading volume Methodology

## 1. Overview

Trading volume measures the total value of trades executed on Pons. Transactional activity across Pons V1, Pons V2 Bonding Curve, and Pons V2 Graduated Pools is captured by this metric. Since trading fees are paid by users on these trades, a strong correlation is observed between this metric and the protocol's ability to generate fees and revenue.

## 2. Data sources

- **Blockchain events**: `CurveBuy` and `CurveSell` events from `Curve` contracts, `TokenLaunched` events from `LaunchFactory`, `TokenFactory`, and `LegacyTokenFactory` contracts, `PoolRegistered` events from `MemeHook` contracts, and `Swap` events from `Pool` and `PoolManager` contracts, covering Robinhood Chain
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Pons V2 Bonding Curve volume extraction

- **Purpose**: Capture trading volume from bonding curve transactions
- **Logic**: `CurveBuy` and `CurveSell` events are parsed from `Curve` contracts. For buy transactions, the volume is extracted from the `quoteIn` field. For sell transactions, the volume is calculated by summing the `quoteOut`, `fee`, and `tax` fields. These transactions are mapped to their respective quote assets using registry data from `TokenLaunched` events emitted by `LaunchFactory` contracts.
- **Key fields**: `quoteIn`, `quoteOut`, `fee`, `tax`, `curve_address`, `token_address`

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

- **Purpose**: Capture trading volume from graduated Uniswap V4 pools
- **Logic**: `Swap` events are parsed from Uniswap V4 `PoolManager` contracts. The trading volume is determined by extracting the absolute value of either `amount0` or `amount1`, depending on whether the quote asset is designated as currency0. Pools are identified and mapped to their quote assets using registry data from `PoolRegistered` events emitted by `MemeHook` contracts.
- **Key fields**: `amount0`, `amount1`, `pool_id`, `token_address`

### Component C: Pons V1 volume extraction

- **Purpose**: Capture trading volume from Pons V1 Uniswap V3 pools
- **Logic**: `Swap` events are parsed from Uniswap V3 pools associated with Pons V1 launches. The trading volume is calculated as the absolute value of the pair asset amount, which is represented by either `token0_amount` or `token1_amount` depending on which asset is designated as token0. Pools are identified and mapped to their quote assets using registry data from `TokenLaunched` events emitted by `TokenFactory` and `LegacyTokenFactory` contracts.
- **Key fields**: `pair_amount`, `token0_amount`, `token1_amount`, `pool_address`, `token_address`

### Component D: Decimal normalization and USD conversion

- **Purpose**: Normalize trading volumes to a standard decimal format and convert them to USD
- **Logic**: Raw trading volumes from all components are aggregated by day, product, and quote asset. The aggregated amounts are normalized by decimal precision using asset metadata, with native ETH assigned a default of 18 decimals. The normalized volumes are then multiplied by end-of-day asset prices to calculate the final trading volume in USD. Daily granularity is maintained using UTC day boundaries.
- **Key fields**: `trading_volume`, `decimals`, `price_usd`, `timestamp`
