Across allows users to send tokens from one chain to another almost immediately without having to wait for the rollup’s challenge period. Liquidity providers provide liquidity and relayers handle the fills and in return they charge a transfer fee (supply-side fees).

Across is a cross-chain token bridge for L2s and rollups. Across was founded by Hart Lambur and launched in 2021.

ACX tokenholders own and govern the protocol. They currently don’t take a cut of the total transfer fees paid by the users (revenue). Across’ investors include Hack VC, Placeholder and Blockchain Capital.

# Across Earnings Methodology

## 1. Overview

Across protocol earnings represent the net financial result after accounting for token incentive expenses against protocol revenue. The metric calculates earnings as revenue minus expenses, where revenue is zero (bridge fees are pass-through to liquidity providers and relayers) and expenses consist of ACX token rewards paid to participants. This results in negative earnings equal to the USD value of token incentives distributed.

## 2. Data sources

- **Ethereum smart contract events**: Parsed `Claimed` events from the AcrossMerkleDistributor contract capturing referral reward distributions
- **Ethereum smart contract events**: Parsed `RewardsWithdrawn` events from the AcceleratingDistributor contract capturing liquidity provider reward distributions  
- **End-of-day price feeds**: ACX token prices used for USD conversion
- **Token metadata**: ACX token decimal precision (18 decimals) for amount normalization

## 3. Step-by-step calculation

### Component A: Token incentive expenses
- **Purpose**: Captures the USD value of ACX token rewards distributed to protocol participants
- **Logic**: Extract reward payment events from two Ethereum contracts. From AcrossMerkleDistributor, collect `Claimed` events where the window index is not zero (excluding initial distributions). From AcceleratingDistributor, collect `RewardsWithdrawn` events for LP rewards. Extract the reward amounts as large numeric values and categorize by reward type (referral vs LP rewards). Convert raw token amounts by dividing by 10^18 to account for ACX token decimals, then multiply by end-of-day USD prices to get dollar values.
- **Key fields**: `amount` and `rewardsToSend` fields contain raw token quantities, `windowIndex` distinguishes reward types, `block_timestamp` for daily grouping

### Component B: Revenue calculation  
- **Purpose**: Determines protocol revenue from bridge operations
- **Logic**: Set revenue to zero for all time periods and chains. This reflects Across's business model where bridge fees collected from users are entirely passed through to liquidity providers and relayers rather than retained as protocol revenue.
- **Key fields**: Revenue value is hardcoded as 0 across all dimensions

### Final aggregation
- **Combining components**: Calculate earnings by subtracting token incentive expenses from revenue (zero), resulting in negative earnings equal to expense amounts
- **Currency conversion**: Token amounts converted to USD using end-of-day ACX prices on the reward distribution date
- **Time aggregation**: Daily boundaries based on Ethereum block timestamps, truncated to day level
- **Final calculation**: Earnings = Revenue (0) - Expenses (USD value of ACX rewards) = negative value representing net cost of incentive programs

Net profit (also profits, net income, profitability) — revenue remaining after subtracting expenses.
