A 1% protocol rate applies to every bonding-curve buy and sell on BNB Chain, Robinhood, X Layer and Monad (2.5% on Morph). Tax tokens pay an additional protocol rate of up to 0.3% of trade volume, on top of the creator's 1%, 3%, 5% or 10% tax.

Flap is a token launchpad on Robinhood Chain, BNB Chain, X Layer, Monad and Morph.

# Flap Trading volume Methodology

## 1. Overview

Trading volume measures the total value of trades executed on Flap's bonding curves. The economic activity generated by users buying and selling assets on the platform is captured by this metric. Since trading fees are paid on these transactions, trading volume is highly correlated with the protocol's ability to generate fees and revenue.

## 2. Data sources

- **Blockchain events**: `TokenQuoteSet`, `TokenBought`, and `TokenSold` events from `Portal` contracts, covering BNB Chain, X Layer, Monad, and Robinhood Chain
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Quote asset identification

- **Purpose**: The quote asset used for each traded asset on the bonding curve is determined.
- **Logic**: `TokenQuoteSet` events from `Portal` contracts are parsed to identify the designated quote asset for each traded asset. The latest event per asset is selected. If no quote asset is set, or if the quote asset is designated as the zero address, the chain's wrapped native asset is assigned as the default quote asset.
- **Key fields**: `token` (traded asset address), `quoteToken` (quote asset address)

### Component B: Trade volume extraction

- **Purpose**: The raw volume of buy and sell transactions is extracted.
- **Logic**: `TokenBought` and `TokenSold` events from `Portal` contracts are parsed to capture all bonding-curve trades. The raw quote asset amount is extracted from the `eth` field of each event.
- **Key fields**: `token` (traded asset address), `eth` (raw quote asset amount)

### Component C: Normalization and USD conversion

- **Purpose**: Raw trade volumes are converted into decimal-normalized USD values.
- **Logic**: The raw quote asset amounts are aggregated by day, chain, and quote asset address. These aggregated amounts are normalized by the decimal precision of the respective quote asset using asset metadata. The normalized volumes are then multiplied by the corresponding end-of-day asset prices to calculate the final trading volume in USD.
- **Key fields**: `timestamp` (daily granularity), `chain_id` (chain identifier), `token_address` (quote asset address), `trading_volume` (USD-denominated volume)
