# Fomo Perps Fees Methodology

## 1. Overview

Fees measures the total economic value paid by users for the execution of perpetual contract trades through Fomo Perps. The protocol's ability to generate economic activity and capture value from perpetual trading volume is reflected by this metric. Fees are generated from fills routed through the Fomo Perps application on Hyperliquid and are denominated in USDC. These fees are aggregated daily to provide institutional investors with a clear view of the protocol's revenue-generating capacity.

## 2. Data sources

- **Blockchain events**: `node_fills` events from the Hyperliquid chain, covering Hyperliquid
- **External data**: Asset classification metadata mapping perpetual markets to underlying asset sectors

## 3. Step-by-step calculation

### Component A: Fomo Perps fill extraction

- **Purpose**: Raw trading fees are extracted from perpetual contract fills routed through the Fomo Perps application.
- **Logic**: `node_fills` events from the Hyperliquid chain are parsed. Transactions are filtered to isolate those where the builder address matches the Fomo builder address. Spot assets (identified by `@` or `/` in the asset identifier) and prediction assets (identified by `#` in the asset identifier) are excluded. Fills are filtered to include only those where the fee asset is USDC. The fee amount is extracted from each qualifying fill.
- **Key fields**: `block_timestamp`, `builder`, `coin`, `fee`, `fee_token`

### Component B: Market and asset type classification

- **Purpose**: Fees are attributed to specific perpetual markets and classified by asset sector.
- **Logic**: The asset identifier is parsed to extract the market issuer and asset symbol. For HIP-3 markets, the issuer is extracted from the prefix of the asset identifier, while native Hyperliquid markets are assigned "hyperliquid" as the issuer. The extracted issuer and asset symbol are joined with the Hyperliquid market asset type dimension table to classify each market into sectors such as tokenized stocks, tokenized commodities, tokenized cryptoassets, stablecoins, forex, or tokenized funds. If no match is found, the asset type is designated as undefined.
- **Key fields**: `coin`, `issuer`, `asset_symbol`, `asset_type`

### Component C: Daily aggregation

- **Purpose**: Fees are aggregated to a daily granularity.
- **Logic**: The extracted USDC fees are summed by day, market, and asset type. Zero-filling is applied to ensure continuous daily data coverage without gaps.
- **Key fields**: `timestamp`, `fees`

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.
