# Fomo Spot Fees Methodology

## 1. Overview

The total economic value generated by users executing swaps on Fomo Spot is measured by Fees. Trading fees are collected in the Solana fee wallet of Fomo Spot during swap transactions. These collected fees are utilized to evaluate the protocol's monetization and overall economic activity. All collected fees are denominated in the traded assets and subsequently converted to USD.

## 2. Data sources

- **Blockchain events**: SPL asset transfers to the Fomo Spot fee wallet, covering Solana
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Solana fee transfer extraction

- **Purpose**: To identify and extract trading fees paid to Fomo Spot on Solana.
- **Logic**: SPL asset transfers are filtered where the recipient owner account matches the designated Fomo Spot fee wallet. Self-transfers are excluded by ensuring the authority account of the transfer does not match the fee wallet account. Only transfers occurring on or after the Fomo Spot launch date are included.
- **Key fields**: `block_timestamp` (timing), `transaction_id` (transaction identifier), `token_address` (asset identification), `authority_address` (signer), `amount` (raw fee quantity).

### Component B: Market attribution

- **Purpose**: To attribute collected fees to their respective trading markets.
- **Logic**: Fee transfers are joined with swap transaction data to identify the traded market asset. The market asset is determined by identifying the non-settlement asset (excluding common settlement assets such as USDC, USDT, USD1, and SOL) involved in the swap. If both assets are settlement assets, SOL is selected as the market asset when paired with a stablecoin; otherwise, the first asset is default-assigned. If no matching swap transaction is found, the fee is attributed directly to the transferred asset address.
- **Key fields**: `transaction_id` (join key), `market_token_address` (market asset identification).

### Component C: USD conversion and aggregation

- **Purpose**: To normalize fee amounts and convert them to USD.
- **Logic**: Raw fee amounts are normalized by the decimal precision of each respective asset using asset metadata. The normalized amounts are then multiplied by the corresponding end-of-day price feeds to calculate the USD value. The USD-denominated fees are aggregated by day, chain, product, and market asset. Daily boundaries are defined using UTC timestamps, and any missing days are zero-filled to ensure a continuous time series.
- **Key fields**: `fees` (USD-denominated fee value), `timestamp` (daily UTC boundary).

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.
