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 Trading volume Methodology

## 1. Overview

BounceFinance trading volume measures the total value of completed fixed-price auctions on the BounceFinance decentralized auction platform. This metric captures the economic activity when auction creators successfully claim their proceeds and fees from completed auctions. The calculation aggregates the total value (proceeds plus fees) of all creator claims across multiple blockchain networks, providing insight into the platform's auction marketplace activity.

## 2. Data sources

- **BounceFinance auction events**: Parsed `BounceFixedSwap_CreatorClaimed` events from Ethereum, Arbitrum, BSC, Gnosis, and Optimism networks, representing when auction creators withdraw proceeds from completed fixed-price auctions
- **Token transfer data**: Blockchain token transfer events from the same networks used to identify the denomination token for each auction payout
- **External price data**: End-of-day token price feeds for USD conversion across all supported tokens
- **Token metadata**: Token decimal information required for proper value calculation and normalization

## 3. Step-by-step calculation

### Component A: Auction creator claims extraction
- **Purpose**: Identifies completed auctions through creator claim events and determines their value
- **Logic**: Extracts `BounceFixedSwap_CreatorClaimed` events across five blockchain networks (Ethereum, Arbitrum, BSC, Gnosis, and Optimism). Each event represents an auction creator withdrawing proceeds from a completed fixed-price auction. The system captures the `amount1` field as proceeds and `txFee` field as platform fees paid by the creator.
- **Key fields**: `block_timestamp` for timing, `transaction_hash` and `log_index` for unique identification, creator `address`, `amount1` as auction proceeds, and `txFee` as transaction fees

### Component B: Token denomination detection  
- **Purpose**: Determines which token was used as payment currency in each auction
- **Logic**: Matches creator claim events with corresponding token transfer events in the same transaction. If a token transfer from the creator address matches exactly the `amount1` value from the claim event, that token is used as the denomination. If no matching transfer is found, the system defaults to the wrapped native token of that blockchain (e.g., WETH on Ethereum, WBNB on BSC).
- **Key fields**: `token_address` for denomination identification, `from_address` matching creator address, `value` matching claim amount

### Component C: Trading volume calculation
- **Purpose**: Calculates total trading volume per auction by combining proceeds and fees
- **Logic**: Sums the `proceeds_amount` and `fees_amount` for each creator claim event to represent the total economic value of each completed auction. This represents the full value exchanged in the auction marketplace.
- **Key fields**: `trading_volume` as the sum of proceeds and fees, maintaining original token denomination

### Final aggregation
- **Combining components**: Aggregates all individual auction volumes, maintaining chain and token denomination information for proper processing
- **Currency conversion**: Applies decimal correction based on each token's metadata, then converts all volumes to USD using end-of-day price feeds matched by token address and date
- **Time aggregation**: Groups all data by day using timestamp truncation to daily boundaries, ensuring consistent daily reporting periods
- **Final calculation**: Produces daily trading volume representing the total USD value of completed BounceFinance fixed-price auctions, with zero-filling applied to dates with no auction activity to maintain continuous time series data
