Auctioneers create auctions on Bounce Finance which users can participate in.

Bounce Finance is a non-custodial auction protocol built on Ethereum and other adjacent blockchains. Bounce Finance was founded by Ryan Fang & Jack Lu and launched in 2020.

AUCTION tokenholders own and govern the protocol. They currently take a cut of the total auction fees paid by auction creators (revenue). Bounce Finance's investors include Coinbase Ventures, Binance Labs, Pantera Capital, etc.

# Bounce Finance Revenue Methodology

## 1. Overview

Bounce Finance revenue measures the total transaction fees collected by the protocol from fixed auction creators when they claim their proceeds. This metric captures the platform fees earned from auction activity across five supported blockchains. The calculation tracks `CreatorClaimed` events from Bounce Finance's FixedSwap contracts and extracts the `txFee` component as protocol revenue, converting all amounts to USD for standardized reporting.

## 2. Data sources

- **Bounce Finance events**: Parsed `CreatorClaimed` events from BounceFixedSwap contracts deployed on Arbitrum, BSC, Ethereum, Gnosis, and Optimism
- **Token transfer data**: Token transfer events from the same five blockchains used to determine fee denomination 
- **Token metadata**: Token contract information including decimal places for accurate amount calculations
- **Price feeds**: End-of-day token price feeds for USD conversion
- **Chain configuration**: Wrapped native token addresses for each supported blockchain as fallback denomination

## 3. Step-by-step calculation

### Component A: Auction creator claim extraction
- **Purpose**: Extracts transaction fees from auction creator claim events across all supported chains
- **Logic**: Identifies `CreatorClaimed` events from BounceFixedSwap contracts on Arbitrum, BSC, Ethereum, Gnosis, and Optimism. For each event, extracts the creator's address, claim amount (`amount1`), and most importantly the transaction fee (`txFee`) that represents protocol revenue. Filters out removed/invalid events and captures transaction metadata including block timestamp and transaction hash.
- **Key fields**: `txFee` (the protocol's revenue amount), `amount1` (total claim amount), creator `address`, `block_timestamp`, `transaction_hash`

### Component B: Fee denomination identification  
- **Purpose**: Determines which token was used to pay the transaction fees by matching with actual token transfers
- **Logic**: Joins creator claim events with token transfer data using transaction hash, creator address as sender, and exact amount matching between the claim amount (`amount1`) and transfer value. This matching process identifies the specific token address used for the fee payment. When no matching token transfer is found in the transaction, applies fallback logic to assume fees were paid in the wrapped native token of that specific blockchain.
- **Key fields**: `token_address` (denomination of the fee), `value` (transfer amount for matching), `from_address` (for creator matching)

### Component C: Multi-chain aggregation
- **Purpose**: Combines auction revenue data from all five supported blockchains into a unified dataset
- **Logic**: Unions the claim and transfer data from Arbitrum, BSC, Ethereum, Gnosis, and Optimism. Assigns chain-specific metadata including version identifiers, business line classification as 'Auction', market sector as 'infrastructure', and business segment as 'other'. Maintains chain separation for later filtering and analysis.
- **Key fields**: `chain` (blockchain identifier), `version` (protocol version), business dimension classifications

### Final aggregation
- **Combining components**: Merges the multi-chain fee data with token denomination information, using the `txFee` amount as the base revenue figure and the identified `token_address` for conversion purposes
- **Currency conversion**: Applies decimal correction based on token-specific decimal places, then converts all fee amounts to USD using end-of-day price feeds matched by token address and date
- **Time aggregation**: Truncates block timestamps to daily boundaries for consistent time-series reporting and aggregation
- **Final calculation**: Sums the USD-converted transaction fees by day, chain, and business dimensions. Applies Token Terminal's revenue finalization process which includes zero-filling for days with no auction activity, population of project metadata, and application of chain availability filters to ensure data quality and completeness across the supported blockchain networks.
