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.

# Collector Crypt Fees Methodology

## 1. Overview

The Fees metric is defined as the total economic value generated by Collector Crypt across its Gacha and Marketplace products. Net financial activity is captured from pack sales and Marketplace royalties, which is then adjusted by subtracting pack buybacks. Pack sales are generated from user payments to purchase card packs, whereas pack buybacks represent payouts returned to users when cards are sold back. Marketplace royalties are collected from secondary trading activity.

## 2. Data sources

- **Blockchain events**: `Paid` and `SoldBack` events from `Gacha` contracts, SPL token transfers, and Solana account activity, covering Solana, Robinhood Chain, and Base
- **External data**: End-of-day price feeds for payment assets

## 3. Step-by-step calculation

### Component A: Gacha pack sales and buybacks on EVM chains

- **Purpose**: Capture net pack sales on EVM-compatible chains
- **Logic**: `Paid` events from `Gacha` contracts are parsed to identify pack purchases made in the chain's designated payment asset by non-team wallets. `SoldBack` events from `Gacha` contracts are parsed to identify pack buybacks paid to non-team sellers. Net EVM pack sales are calculated by subtracting the buyback amounts from the purchase amounts.
- **Key fields**: `amount` (payment value), `token_address` (payment asset identification), `signer` (user address)

### Component B: Gacha pack sales and buybacks on Solana

- **Purpose**: Capture net pack sales on Solana
- **Logic**: SPL token transfers of USDC to designated Gacha program accounts by non-team authorities are aggregated to determine pack purchases. Solana account activity is parsed to track USDC outflows from Gacha program accounts, and any direct transfers from these accounts to team wallets are subtracted to isolate user buybacks. Net Solana pack sales are calculated by subtracting these buyback outflows from the pack purchase inflows.
- **Key fields**: `amount` (transfer value), `token_address` (USDC asset identification), `signer` (user account)

### Component C: Marketplace royalties on Solana

- **Purpose**: Capture secondary trading royalties on Solana
- **Logic**: SPL token transfers of USDC to the designated royalty account are parsed and aggregated. Only transfers matching the royalty account are included to represent secondary Marketplace fees.
- **Key fields**: `amount` (royalty value), `token_address` (USDC asset identification), `signer` (user account)

### Component D: USD conversion and aggregation

- **Purpose**: Normalize and aggregate all net fee flows into USD
- **Logic**: Net fee amounts from EVM pack sales, Solana pack sales, and Solana Marketplace royalties are combined. All collected amounts are normalized by decimal precision and converted to USD using end-of-day price feeds. The final values are aggregated daily using UTC day boundaries.
- **Key fields**: `fees` (aggregated fee value), `timestamp` (daily interval)
