# Fomo Perps Trade count Methodology

## 1. Overview

Trade count is measured as the number of perpetual contract trades executed through Fomo Perps. The frequency of user trading activity and overall engagement with the platform's perpetual trading interface is reflected by this metric. Each trade is represented by a builder-attributed fill executed on the Hyperliquid L1 (Hypercore) network. Liquidity and transaction volume trends driven specifically by the Fomo Perps user interface are assessed using this metric.

## 2. Data sources

- **Blockchain events**: `node_fills` records from Hypercore, covering Hyperliquid

## 3. Step-by-step calculation

### Component A: Fomo Perps fill filtering and attribution

- **Purpose**: To identify and isolate perpetual trading fills executed specifically through the Fomo Perps interface.
- **Logic**: Raw `node_fills` records from Hypercore are filtered to include only those where the `builder` field matches the designated Fomo builder address. Spot trading pairs (identified by the presence of `@` or `/` in the coin identifier) and outcome markets (identified by `#` in the coin identifier) are excluded to isolate perpetual contracts. Only fills occurring on or after the Fomo Perps launch date are retained.
- **Key fields**: `block_timestamp`, `builder`, `coin`

### Component B: Fomo Perps trade count aggregation

- **Purpose**: To calculate the daily trade count for Fomo Perps.
- **Logic**: Every filtered fill record is treated as one trade. The total number of records is aggregated by truncating the block timestamp to daily granularity and counting the total number of fills. No taker-only filters are applied, meaning every builder-tagged fill is counted.
- **Key fields**: `block_timestamp`

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.
