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 Token incentives Methodology

## 1. Overview

Token incentives measures the total USD value of token rewards distributed by the Across protocol to users on a daily basis. This includes both referral rewards and liquidity provider (LP) rewards paid out in ACX tokens. The metric tracks protocol spending on user incentives and rewards programs, providing insight into the protocol's growth investment and user acquisition costs.

## 2. Data sources

The calculation uses the following raw data sources:
- **Across v1 smart contract events**: Parsed `AcrossMerkleDistributor_Claimed_event` and `AcceleratingDistributor_RewardsWithdrawn_event` from Ethereum blockchain
- **End-of-day price feeds**: ACX token prices for USD conversion
- **Token metadata**: ACX token decimal configuration for proper amount calculation

## 3. Step-by-step calculation

### Component A: Referral rewards extraction
- **Purpose**: Captures referral rewards claimed by users from the Across MerkleDistributor contract
- **Logic**: Extracts `AcrossMerkleDistributor_Claimed_event` logs from Ethereum, filtering out entries where `windowIndex` equals zero (which appear to be invalid or test transactions). Records the claiming account address, claimed amount, transaction hash, log index, and block timestamp. All referral rewards are paid in ACX tokens from the hardcoded ACX contract address.
- **Key fields**: `address` (recipient), `amount` (ACX tokens claimed), `windowIndex` (filtering mechanism), `transaction_hash`, `block_timestamp`

### Component B: LP rewards extraction  
- **Purpose**: Captures liquidity provider rewards withdrawn from the Across AcceleratingDistributor contract
- **Logic**: Extracts `AcceleratingDistributor_RewardsWithdrawn_event` logs from Ethereum, recording the withdrawing account address, rewards amount sent, transaction hash, log index, and block timestamp. All LP rewards are also paid in ACX tokens from the same hardcoded ACX contract address.
- **Key fields**: `address` (recipient), `rewardsToSend` (ACX tokens withdrawn), `transaction_hash`, `block_timestamp`

### Component C: Reward aggregation
- **Purpose**: Combines both reward types into a unified dataset with consistent classification
- **Logic**: Unions referral rewards and LP rewards data, standardizing the schema with reward type labels ('Referral rewards' vs 'LP rewards'), ACX token address, Ethereum chain designation, and v1 version tagging. Casts token amounts to high-precision numeric format to handle large token values accurately.
- **Key fields**: `reward_type` (classification), `token_address` (ACX), `chain` (ethereum), `reward_amount` (standardized amount field)

### Final aggregation
- **Combining components**: All reward events are aggregated by day using timestamp truncation to daily boundaries, grouping by account address, transaction hash, and reward metadata
- **Currency conversion**: ACX token amounts are converted to USD using end-of-day price feeds, with automatic decimal correction applied based on ACX token metadata (18 decimals)
- **Time aggregation**: Daily summation of all token incentives paid out, with timestamp truncated to day level for consistent daily reporting
- **Final calculation**: The final metric value represents the total USD value of ACX tokens distributed as incentives each day, including both referral and LP rewards, with missing days filled with zero values to ensure complete time series
