# Marketplace Fees Methodology

## 1. Overview

Fees for the Marketplace product of Collector Crypt are measured by the total economic value generated from secondary market trading royalties. These fees are collected in USDC on Solana when assets are traded on the Marketplace, with a portion of the transaction value directed to a designated royalty wallet. This metric is utilized to assess the economic value generated by secondary trading activity within the Marketplace ecosystem.

## 2. Data sources

- **Blockchain events**: SPL asset transfers, covering Solana
- **External data**: End-of-day price feeds for USDC

## 3. Step-by-step calculation

### Component A: Royalty fee extraction

- **Purpose**: Capture royalty fees generated from secondary market trades on the Marketplace
- **Logic**: SPL asset transfers on Solana are filtered to identify transactions where the recipient owner account matches the designated royalty wallet. Only transfers of the USDC asset are included. The transfer amounts are extracted to represent the raw royalty fees.
- **Key fields**: `amount` (fee quantities), `token_address` (asset identification), `to_owner_address` (recipient identification)

### Component B: USD conversion and aggregation

- **Purpose**: Normalize royalty fee values to USD and aggregate them on a daily basis
- **Logic**: Raw royalty fee amounts are normalized by decimal precision. The normalized amounts are then multiplied by end-of-day price feeds for USDC to convert the values to USD. The converted values are aggregated to a daily granularity using UTC day boundaries.
- **Key fields**: `timestamp` (daily boundary), `fees` (aggregated USD value)

Fees

NFT marketplaces

Users pay USDC to open gacha packs, each of which reveals a tokenized graded trading card. Users can sell a card back to the platform for USDC or redeem the physical card from the vault. The platform also earns royalties from marketplace trades.

Collector Crypt tokenizes graded physical trading cards, such as Pokémon, as NFTs on Solana. Cards are authenticated and held in secure vaults. The platform consists of a gacha pack experience and a secondary marketplace, and has its own CARDS token.

Collector Crypt is a Solana-based collectibles platform led by CEO Tuomas Holmberg.
