# Fomo Perps Notional trading volume Methodology

## 1. Overview

Notional trading volume measures the total value of derivative contracts executed on Fomo Perps. This metric represents the aggregate USD value of all perpetual futures trades routed through the Fomo application. Since trading fees are paid on each transaction, this metric is utilized as a key indicator of the protocol's ability to generate fees and revenue. Every trade leg carrying the Fomo builder attribution is summed without deduplication to capture all user trading activity.

## 2. Data sources

- **Blockchain events**: Node fill events from the Hypercore chain
- **Asset metadata**: Market asset type mappings for Hyperliquid and HIP-3 deployers

## 3. Step-by-step calculation

### Component A: Fomo Perps trade extraction

- **Purpose**: Extract and filter perpetual trade fills executed through the Fomo application
- **Logic**: Node fill events are parsed from the Hypercore chain. Trades are filtered to include only those carrying the specific Fomo builder address. Spot markets (identified by `@` or `/` in the market symbol) and outcome/prediction markets (identified by `#` in the market symbol) are excluded. Only trades executed on or after the Fomo Perps launch date in June 2026 are retained.
- **Key fields**: `block_timestamp`, `coin`, `size`, `price`, `builder`

### Component B: Market and asset classification

- **Purpose**: Attribute trades to their respective market issuers and asset classes
- **Logic**: The market issuer and asset symbol are extracted from the market identifier. If the market identifier contains a colon, it is split to separate the HIP-3 deployer prefix (issuer) and the asset symbol; otherwise, the issuer is classified as native Hyperliquid. These identifiers are joined with market asset type metadata to classify each trade into its corresponding asset class (such as tokenized stocks, tokenized commodities, or tokenized cryptoassets), with unmapped markets defaulting to an undefined classification.
- **Key fields**: `coin`, `issuer`, `asset_symbol`, `asset_type`

### Component C: Notional volume calculation and aggregation

- **Purpose**: Calculate the USD value of trades and aggregate them
- **Logic**: Notional trading volume is calculated for each trade by multiplying the trade size by the fill price. These values are summed and aggregated by day, market, asset symbol, issuer, and asset type. Daily totals are then aggregated to produce the final metric, with zero-filling applied to ensure continuity across days.
- **Key fields**: `size`, `price`, `notional_trading_volume`

DEX aggregators

Fomo earns a fee on every trade placed through the app. On perpetuals it acts as a Hyperliquid builder: each order placed from the app carries Fomo's builder code, and Hyperliquid routes a 0.05% builder fee per side to Fomo's builder address at trade time, on top of the venue's own fee and any HIP-3 deployer share. On spot swaps Fomo charges a platform fee collected in its own fee wallets; on cross-chain swaps routed through Relay, Relay collects Fomo's app fee and settles it as USDC to Fomo's fee collector on Base.

Fomo offers perpetual contracts on crypto, US equities, pre-IPO companies, indices and commodities through Hyperliquid's native markets and HIP-3 markets such as trade.xyz, alongside spot trading of memecoins and other tokens. The app is available on iOS, Android and the web at fomo.family.

Fomo is a mobile-first social trading app built by FOMO Labs, Inc., founded in 2025 by former dYdX employees. It combines a social feed, leaderboards and copy trading with self-custodial, gasless token swaps on Solana, Robinhood Chain, Base, BNB Chain and Monad, and since June 2026 perpetual futures executed on Hyperliquid. Fomo is operated as a private company; no token has been issued.
