# dreamcash CAR Active users (monthly) Methodology

## 1. Overview

This page covers the CAR market (`cash:CAR`) on dreamcash, one of the markets deployed under the `cash` namespace on Hyperliquid HyperCore. The calculation is identical across all dreamcash markets; the figures on this page are scoped to the CAR market.

Active users (monthly) measures the number of unique addresses that execute revenue-generating trades on dreamcash products, such as `cash:USA500` and `cash:TSLA`. This metric captures both makers and takers participating in perpetual swap markets deployed via the dreamcash protocol. User activity is identified through trade fill events on the Hyperliquid blockchain, specifically targeting markets registered under the dreamcash namespace.

## 2. Data sources

- **Blockchain events**: `node_fills` data from HyperCore contracts, covering Hyperliquid

## 3. Step-by-step calculation

### Component A: Trade fill extraction

- **Purpose**: Identify all trading activity occurring on dreamcash-deployed markets
- **Logic**: Trade fill data is parsed from HyperCore contracts on the Hyperliquid blockchain. Markets are filtered to include only those where the asset symbol carries the `cash:` prefix, which signifies a market deployed by the dreamcash protocol. Trader addresses are extracted from the account fields of these fill events, capturing participants on both the maker and taker sides of every matched trade.
- **Key fields**: `account_address` (trader identification), `coin` (market identification), `block_timestamp` (timing)

### Component B: Monthly unique address aggregation

- **Purpose**: Calculate the total count of unique participants per 30-day window
- **Logic**: The extracted trader addresses are aggregated and deduplicated to determine the number of unique active users. This count is calculated over 30-day rolling windows. Monthly granularity is maintained using UTC day boundaries.
- **Key fields**: `trader_address` (unique identifier), `block_timestamp` (temporal grouping)

Derivative markets

dreamcash earns a deployer share of trading fees on the perpetual markets it has deployed under Hyperliquid's HIP-3 framework. Markets execute on Hyperliquid's HyperCore L1 order book; it does not operate its own matching engine. The default HIP-3 fee split allocates 50% of each user-paid fee to Hyperliquid and 50% to the deployer; deployerFeeScale is 1.0, so the standard split applies.

dreamcash offers USDC-settled perpetual contracts on US equities (NVDA, TSLA, AMZN, MSFT, META, GOOGL, INTC, HOOD), indices (USA500, EWY, KWEB), and commodities (gold, silver, WTI). All 15 markets are deployed under the HIP-3 `cash` namespace and execute on Hyperliquid's HyperCore order book.

dreamcash is a HIP-3 (builder-deployed perpetuals) deployer on Hyperliquid, deployed by wallet 0xffa8198c62adb1e811629bd54c9b646d726deef7. dreamcash is operated as a private company; no token has been issued.
