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.

# Fomo Active users (weekly) Methodology

## 1. Overview

Active users (weekly) is measured as the number of unique accounts that execute revenue-generating transactions on Fomo. User interactions across Fomo Perps, Fomo Spot, and Fomo Cross-chain are captured by this metric. The metric is utilized to evaluate user adoption, engagement, and overall protocol utility. Active users (weekly) are aggregated over a 7-day rolling window ending at UTC midnight.

## 2. Data sources

- **Blockchain events**: SPL asset transfers on Solana and `node_fills` events on Hyperliquid, covering Solana and Hyperliquid

## 3. Step-by-step calculation

### Component A: Fomo Perps user tracking

- **Purpose**: Identify unique traders executing perpetual contract trades
- **Logic**: Node fill events from the `node_fills` table on Hyperliquid are filtered to isolate trades routed through the Fomo builder account. Spot and outcome assets are excluded by filtering out asset symbols containing specific characters (such as `@`, `/`, or `#`). The trader account is extracted from the account field of the fill event.
- **Key fields**: `block_timestamp` (timing), `account_address` (user identification), `builder` (attribution filtering), `coin` (asset filtering)

### Component B: Fomo Spot user tracking

- **Purpose**: Identify unique traders executing spot swaps on Solana
- **Logic**: SPL asset transfers on Solana are filtered where the recipient account matches the designated Fomo fee wallet account. Transfers where the authority account matches the fee wallet account are excluded to prevent self-transfers. The trading user is identified as the authority account of the transfer.
- **Key fields**: `block_timestamp` (timing), `authority_address` (user identification), `to_owner_address` (recipient filtering)

### Component C: Fomo Cross-chain user tracking

- **Purpose**: Identify unique users executing cross-chain swaps settled via Relay
- **Logic**: Cross-chain transactions are split into buy and sell directions. For buy transactions, USDC transfers to the Relay deposit vault account are identified where the transaction signer matches a designated Fomo relayer account, and the user is identified as the transfer authority account. For sell transactions, USDC transfers from the Relay fill wallet account are captured. A recipient account of a sell transfer is classified as a Fomo user only if that account has previously executed a Fomo Spot trade or a Fomo Cross-chain buy transaction on or before the 7-day window of the transfer.
- **Key fields**: `block_timestamp` (timing), `authority_address` (user identification), `to_owner_address` (recipient identification), `transaction_signer` (relayer filtering)

### Component D: Weekly aggregation

- **Purpose**: Consolidate unique users across all products and calculate active users (weekly)
- **Logic**: User accounts identified from Fomo Perps, Fomo Spot, and Fomo Cross-chain are unioned into a single dataset. The number of unique user accounts is aggregated per 7-day window, chain, and product. Active users (weekly) is calculated by taking the distinct count of these accounts over 7-day rolling UTC intervals.
- **Key fields**: `block_timestamp` (timing), `user_address` (user identification), `product_id` (product categorization)
