# Gacha Revenue Methodology

## 1. Overview

Revenue is defined as the portion of fees that is retained by the protocol. For the Gacha product of Collector Crypt, all generated fees are retained by the protocol, as no portion is distributed to supply-side participants. This metric is calculated by aggregating pack sales and subtracting pack buybacks, representing the net earnings generated from Gacha activities. All calculated values are normalized and converted to USD to provide a standardized view of the product's primary income stream.

## 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 and asset metadata

## 3. Step-by-step calculation

### Component A: EVM pack sales and buybacks

- **Purpose**: Capture net pack sales on EVM-compatible chains.
- **Logic**: Pack purchases are extracted from `Paid` events emitted by `Gacha` contracts, where the payment asset matches the designated stable asset on each chain and the payer is verified to not belong to a list of designated team accounts. Pack buybacks, representing cards sold back to the protocol, are extracted from `SoldBack` events emitted by `Gacha` contracts, with transactions initiated by team accounts excluded. Net EVM flows are determined by subtracting the buyback amounts from the pack purchase amounts.
- **Key fields**: `amount`, `token_address`, `signer`

### Component B: Solana pack sales

- **Purpose**: Capture pack purchase fees on Solana.
- **Logic**: Pack purchases are identified via SPL token transfers of USDC to designated Gacha program accounts. Transfers initiated by designated team accounts are excluded from the aggregation.
- **Key fields**: `amount`, `token_address`, `signer`

### Component C: Solana pack buybacks

- **Purpose**: Capture pack buyback outflows on Solana.
- **Logic**: Outflows are tracked by monitoring Solana account activity for USDC balance reductions on designated Gacha program accounts. To isolate user buybacks, any direct transfers from these Gacha accounts to designated team accounts are subtracted from the total outflows.
- **Key fields**: `amount`, `token_address`, `signer`

### Component D: USD conversion and revenue aggregation

- **Purpose**: Combine net flows, normalize by decimals, and convert to USD.
- **Logic**: Net flows from EVM pack sales, EVM pack buybacks, Solana pack sales, and Solana pack buybacks are aggregated. All transaction amounts are normalized by decimal precision using asset metadata and multiplied by end-of-day asset prices to determine the USD value. Since there are no supply-side fees associated with the Gacha product, 100% of the net fees are allocated to protocol revenue. Daily values are aggregated using UTC day boundaries.

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.
