# Fomo Cross-chain Revenue Methodology

## 1. Overview

Revenue is measured as the portion of fees that is retained by Fomo Cross-chain from its cross-chain swap operations. For Fomo Cross-chain, a 100% take rate is applied, meaning all collected fees are retained as protocol revenue. These fees are accumulated off-chain and settled on-chain via USDC transfers from Relay solvers to the Fomo fee collector address. This metric is utilized as a key indicator of the protocol's financial performance and the volume of cross-chain swap activity routed through the platform.

## 2. Data sources

- **Blockchain events**: ERC-20 `Transfer` events, covering Base
- **External data**: End-of-day price feeds for USDC

## 3. Step-by-step calculation

### Component A: Fomo Cross-chain fee settlement tracking

- **Purpose**: Identify and extract fee settlement transfers from Relay solvers to the Fomo fee collector
- **Logic**: ERC-20 `Transfer` events are filtered to isolate transactions on Base where the recipient address matches the Fomo fee collector, the asset transferred is USDC, and the sender address belongs to a known Relay solver. Transfers with a value of zero or less are excluded. The raw transfer amounts are captured along with their block timestamps.
- **Key fields**: `block_timestamp` (timing), `amount` (transfer value), `token_address` (asset identification), `from_address` (sender identification), `to_address` (recipient identification)

### Component B: USD conversion and normalization

- **Purpose**: Normalize fee amounts by decimal precision and convert them to USD
- **Logic**: Raw fee amounts are normalized by dividing the transfer values by the decimal precision of the USDC asset. The normalized amounts are then multiplied by the end-of-day USD price of USDC sourced from end-of-day price feeds to determine the fee value in USD.
- **Key fields**: `fees` (normalized and priced in USD)

### Component C: Revenue aggregation

- **Purpose**: Aggregate fees to calculate total daily protocol revenue for Fomo Cross-chain
- **Logic**: Because 100% of collected fees are retained by Fomo Cross-chain, protocol revenue is set equal to the calculated fees. The USD-denominated revenue values are aggregated by day using UTC day boundaries. Any days without activity are filled with zero values to ensure a continuous daily time series.
- **Key fields**: `timestamp` (day boundary), `revenue` (daily aggregated USD value)

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.
