# Pons V2 Bonding Curve Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of fees that goes to service providers. For Pons V2 Bonding Curve, these fees are composed of creator earnings and asset buyback allocations accumulated during bonding curve trading. This metric is used to evaluate the economic incentives provided to asset creators and the buyback pressure generated for launched assets. All collected fees are denominated in the respective quote assets and converted to USD.

## 2. Data sources

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

## 3. Step-by-step calculation

### Component A: Bonding curve mapping

- **Purpose**: Map active bonding curves to their respective quote assets.
- **Logic**: `TokenLaunched` events from `LaunchFactory` contracts are parsed to identify newly launched bonding curves. The curve address and the quote asset address (where the zero address represents the native asset) are extracted to establish a registry of active Pons V2 Bonding Curve contracts.
- **Key fields**: `curve` (curve address), `pairToken` (quote asset address)

### Component B: Fee extraction and allocation

- **Purpose**: Extract and categorize fees collected from bonding curve activity.
- **Logic**: `FeesSwept` events from `Curve` contracts are parsed and joined with the bonding curve registry. The creator fee amount and the buyback fee amount are extracted from each event. Launch fees from `TokenLaunched` events are also captured, but zero supply-side fee allocations are applied to these events as they are designated entirely for the protocol.
- **Key fields**: `creator_amount` (creator fee allocation), `buyback_amount` (buyback fee allocation), `pairToken` (quote asset address)

### Component C: Normalization and USD conversion

- **Purpose**: Normalize fee amounts by decimal precision and convert them to USD.
- **Logic**: Daily fee amounts are aggregated by quote asset. These amounts are normalized by the decimal precision of each asset, which is retrieved from asset metadata (with native assets set to 18 decimals). The normalized supply-side fees, calculated as the sum of the creator amount and the buyback amount, are multiplied by end-of-day price feeds to determine the final USD value.
- **Key fields**: `creator_amount` (creator fee allocation), `buyback_amount` (buyback fee allocation), `decimals` (asset decimal precision), `price_usd` (asset price in USD)

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.
