Creators create and sell NFTs on Zora. They receive a cut of the primary sales (supply-side fees).

Zora is a non-custodial NFT minting protocol built on Ethereum and launched in 2021.

Team and investors own and govern the protocol. They currently take a cut the primary sales paid by collectors (revenue).

# Zora Fees Methodology

## 1. Overview

The Zora fees metric measures the total fees generated by the Zora NFT marketplace, treating all trading volume as fees paid to creators and the protocol. This metric combines explicit fee payouts tracked by the protocol with the full purchase amounts users pay for NFT mints, providing a comprehensive view of economic activity and value flow within the Zora ecosystem.

## 2. Data sources

- **Zora contract events**: Parsed `721Drop_MintFeePayout_event`, `721Drop_Sale_event`, and `1155_Purchased_event` logs from Zora's smart contracts deployed on Ethereum, Optimism, and Base
- **NFT marketplace transactions**: Both ERC721 and ERC1155 token mint and sale events from Zora's NFT marketplace contracts
- **Price feeds**: End-of-day token price feeds for WETH on Ethereum, Optimism, and Base chains
- **Token metadata**: Decimal precision and contract information for native chain tokens used in transactions

## 3. Step-by-step calculation

### Component A: Fee payout tracking
- **Purpose**: Captures explicit mint fees paid to the protocol during NFT creation
- **Logic**: Extracts `721Drop_MintFeePayout_event` logs from Zora contracts across Ethereum, Optimism, and Base. Filters events by contract address and retrieves the `mintFeeAmount` field which represents the fee amount paid during NFT minting. Includes transaction metadata like `block_timestamp`, `transaction_hash`, and `log_index` for traceability
- **Key fields**: `mintFeeAmount` represents the fee amount, `address` identifies the NFT contract, chain-specific WETH token addresses for value denomination

### Component B: NFT mint and sale tracking  
- **Purpose**: Captures the full purchase amounts users pay when minting or buying NFTs
- **Logic**: Combines two event types - `721Drop_Sale_event` for ERC721 tokens and `1155_Purchased_event` for ERC1155 tokens. For ERC721 events, calculates the total amount as `quantity` multiplied by `pricePerToken`. For ERC1155 events, uses the direct `value` field. Includes business classification metadata like marketplace segment and NFT market sector
- **Key fields**: `quantity` and `pricePerToken` for ERC721 calculations, `value` for ERC1155 transactions, `address` for NFT contract identification

### Final aggregation
- **Combining components**: Unions fee payout amounts with NFT purchase amounts into a single trading volume dataset, treating both as contributions to total fees
- **Currency conversion**: Converts native token amounts (WETH) to USD using end-of-day price feeds and applies proper decimal correction based on token precision
- **Time aggregation**: Truncates timestamps to daily boundaries and groups transactions by day for daily fee totals
- **Final calculation**: Sums all fee payouts and purchase amounts per day to generate the total fees metric, applies standardized metric formatting, and fills missing days with zero values to maintain continuous time series data
