# Active users (monthly) Methodology

## 1. Overview

Active users (monthly) is defined as the number of unique accounts that execute a revenue-generating cross-chain transaction through Fomo Cross-chain within a 30-day rolling window. This metric is utilized to evaluate user adoption, engagement, and transaction activity specifically for the cross-chain swap product. By aggregating unique transacting accounts monthly, the protocol's growth and utility in cross-chain settlement are assessed.

## 2. Data sources

- **Blockchain events**: USDC transfers on Solana settled through Relay deposit and fill accounts

## 3. Step-by-step calculation

### Component A: Cross-chain buy tracking

- **Purpose**: Identifies user accounts executing cross-chain buy transactions
- **Logic**: USDC transfers on Solana are filtered to isolate deposits into the Relay deposit vault. Transactions are qualified if the transaction signer matches a designated Fomo relayer account. The user account is identified as the authority account of the transfer
- **Key fields**: `block_timestamp` (timing), `user_address` (user account identification), `amount` (transfer volume)

### Component B: Cross-chain sell tracking

- **Purpose**: Identifies user accounts executing cross-chain sell transactions
- **Logic**: USDC transfers on Solana from the Relay fill wallet are analyzed. To verify these transfers represent Fomo sell transactions, the recipient account is matched against a historical record of all Fomo actions, which includes Fomo Spot fees and Fomo Cross-chain buys. A transfer is classified as a sell only if the recipient account has a recorded Fomo interaction on or before the day of the transfer
- **Key fields**: `block_timestamp` (timing), `user_address` (user account identification), `amount` (transfer volume)

### Component C: Monthly active user aggregation

- **Purpose**: Aggregates unique accounts to calculate active users (monthly)
- **Logic**: The user accounts identified from both buy and sell transactions are combined. Duplicate accounts are removed within each 30-day rolling window to yield the count of unique active users (monthly) for Fomo Cross-chain
- **Key fields**: `block_timestamp` (timing), `user_address` (user account identification)

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.
