# Fomo Cross-chain Trade count Methodology

## 1. Overview

The number of trades executed on a decentralized exchange is measured by trade count. The frequency with which assets are bought or sold through the project is shown by this metric. For Fomo Cross-chain, transaction frequency and user engagement for cross-chain swaps settled via the Relay network are indicated by this metric. Insights into the protocol's liquidity utilization and adoption are provided by tracking the volume of distinct trade transactions. Each trade is represented by a Solana-based transaction corresponding to a cross-chain swap leg.

## 2. Data sources

- **Blockchain events**: SPL token `Transfer` instructions on Solana, covering Solana

## 3. Step-by-step calculation

### Component A: Fomo Cross-chain buy identification

- **Purpose**: Cross-chain buy transactions settled through Relay are identified.
- **Logic**: SPL token `Transfer` instructions of the USDC asset to the Relay deposit vault account are filtered. Transactions are classified as buys if the transaction signer is identified as one of the designated Fomo relayer accounts. Only swaps initiated through Fomo Cross-chain and settled via Relay are captured by this filtering process.
- **Key fields**: `block_timestamp`, `transaction_id`, `authority_address` (user account), `token_address`, `amount`

### Component B: Fomo Cross-chain sell identification

- **Purpose**: Cross-chain sell transactions settled through Relay are identified.
- **Logic**: SPL token `Transfer` instructions of the USDC asset from the Relay fill wallet account to user accounts are analyzed. To ensure these transfers are classified as Fomo Cross-chain trades, a recorded history of trading through Fomo on or before the day of the transfer must be associated with the recipient account. This historical activity is verified by checking previous fee-paying swaps or relayer-paid deposits.
- **Key fields**: `block_timestamp`, `transaction_id`, `to_owner_address` (user account), `token_address`, `amount`

### Component C: Trade count aggregation

- **Purpose**: The daily trade count for Fomo Cross-chain is calculated.
- **Logic**: Buy and sell transactions are combined into a unified dataset. The total trade count is calculated by taking the daily count of distinct transaction identifiers associated with Fomo Cross-chain. The final metric is aggregated with daily granularity using UTC day boundaries, and any days without activity are zero-filled.
- **Key fields**: `block_timestamp`, `transaction_id`

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.
