# Pons V2 Bonding Curve Fees Methodology

## 1. Overview

Fees measures the total economic value paid by users to interact with the Pons V2 Bonding Curve product. Both the flat creation fees paid during asset launches and the ongoing swap fees accumulated during bonding curve trading are captured by this metric. These fees are distributed to various protocol participants, including the protocol treasury, buyback mechanisms, and asset creators. The overall economic activity and monetization efficiency of the Pons V2 Bonding Curve platform are reflected through this metric.

## 2. Data sources

- **Blockchain events**: `TokenLaunched` events from `LaunchFactory` contracts and `FeesSwept` events from `Curve` contracts, covering Robinhood Chain
- **External data**: End-of-day price feeds and asset metadata for decimal normalization

## 3. Step-by-step calculation

### Component A: Token launch fee extraction

- **Purpose**: To capture the flat fee paid by creators to launch a new asset on the bonding curve.
- **Logic**: `TokenLaunched` events from `LaunchFactory` contracts are parsed to identify new asset deployments. For each launch event, a flat protocol fee of 500,000,000,000,000 wei of the native asset is recorded as protocol revenue.
- **Key fields**: `block_timestamp` (timing), native asset address (asset identification).

### Component B: Bonding curve swap fee extraction

- **Purpose**: To capture the trading fees accumulated and swept from active bonding curves.
- **Logic**: `FeesSwept` events from `Curve` contracts are parsed and joined with bonding curve deployment data from `LaunchFactory` contracts. The swept amounts are extracted and categorized into protocol fees, buyback fees, and creator fees. These components are summed to represent the total swap fees generated by the bonding curve.
- **Key fields**: `protocolAmount` (protocol share), `buybackAmount` (buyback share), `creatorAmount` (creator share), `token_address` (quote asset identification).

### Component C: Normalization and USD conversion

- **Purpose**: To standardize fee amounts across different assets and convert them to USD.
- **Logic**: The extracted launch fees and swap fees are aggregated by day, asset, and product. Raw amounts are normalized by decimal precision using asset metadata. The normalized values are then multiplied by end-of-day asset prices to calculate the daily fee volume in USD. Daily boundaries are defined using UTC timestamps.

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.
