# Fomo Cross-chain Supply-side fees Methodology

## 1. Overview

Supply-side fees is defined as the share of transaction fees that is distributed to service providers or external supply-side participants. For Fomo Cross-chain, this metric is set to zero. All fees collected from cross-chain swaps are fully retained by the protocol as revenue, meaning no portion is allocated to external supply-side operators. Consequently, no supply-side fee distribution is recorded for this product.

## 2. Data sources

- **None**: This metric is set to a constant value and no blockchain events are consumed

## 3. Step-by-step calculation

### Component A: Supply-side fee allocation

- **Purpose**: To determine the portion of fees distributed to supply-side participants
- **Logic**: The metric is hardcoded to zero for Fomo Cross-chain. Because 100% of the fees generated by cross-chain swaps are classified as protocol revenue, a net supply-side fee of zero is calculated when revenue is subtracted from total fees.

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.
