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 Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute trades and swaps across the Fomo platform. Economic value generation is captured across three distinct products: Fomo Perps, Fomo Spot, and Fomo Cross-chain. For Fomo Perps, gross transaction fees paid on perpetual contract fills routed through the platform are recorded. For Fomo Spot, token transfers into the Solana fee wallet account are aggregated. For Fomo Cross-chain, off-chain accrued fees settled in USDC on Base by Relay solvers are captured.

## 2. Data sources

- **Blockchain events**: Node fill events, SPL token transfer instructions, and ERC-20 `Transfer` events, covering Hypercore, Solana, and Base
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Fomo Perps fee extraction

- **Purpose**: To capture gross transaction fees from perpetual trading routed through Fomo
- **Logic**: Node fill events on Hypercore are filtered to isolate trades placed through the Fomo application by matching the builder account. Spot and outcome markets are excluded by filtering out assets prefixed with `@` or `#`, or containing `/`. Fees are extracted from the `fee` field where the fee asset is USDC. Markets are mapped to their respective asset types (such as tokenized stocks, commodities, or cryptoassets) using asset metadata.
- **Key fields**: `block_timestamp`, `coin`, `asset_symbol`, `issuer`, `fee`

### Component B: Fomo Spot fee extraction

- **Purpose**: To capture trading fees from spot swaps on Solana
- **Logic**: SPL token transfer instructions to the Fomo Solana fee wallet account are parsed. Transfers where the authority account matches the fee wallet account are excluded to prevent self-transfers. Each fee transfer is joined with swap data to attribute the fee to the specific market asset traded.
- **Key fields**: `block_timestamp`, `transaction_id`, `token_address`, `amount`

### Component C: Fomo Cross-chain fee extraction

- **Purpose**: To capture settled cross-chain swap fees
- **Logic**: ERC-20 `Transfer` events on Base are parsed to identify USDC transfers from authorized Relay solver addresses to the Fomo fee collector address. These transfers are recognized as the on-chain settlement of off-chain accrued cross-chain application fees.
- **Key fields**: `block_timestamp`, `from_address`, `to_address`, `token_address`, `value`

### Component D: USD conversion and aggregation

- **Purpose**: To normalize fee values to USD and aggregate them
- **Logic**: Fee amounts from all three products are normalized by decimal precision. Spot and cross-chain fees are multiplied by end-of-day asset prices to convert them to USD, while perpetual fees are processed directly as USDC. The USD values are aggregated daily by product and market using UTC day boundaries.
