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 Treasury (net) Methodology

## 1. Overview

Treasury net represents the total USD value of tokens held in Across Protocol's treasury addresses. This metric tracks the protocol's token holdings over time by monitoring balance changes in specific treasury wallets, calculating cumulative balances, and converting to USD using daily price feeds. It provides insight into the protocol's financial position and asset management.

## 2. Data sources

- **Blockchain events**: Parsed Ethereum `Transfer` events and token transaction logs for tracking token movements
- **Transaction data**: Ethereum transaction records and traces for balance calculations
- **External data**: End-of-day token price feeds for USD conversion
- **Token metadata**: Token symbol and decimal information for proper balance calculations

## 3. Step-by-step calculation

### Component A: Treasury balance tracking
- **Purpose**: Tracks token balance changes for Across Protocol's treasury addresses
- **Logic**: Processes token transfer events and transaction data for the specific treasury address `0xb524735356985d2f267fa010d681f061dff03715` on Ethereum. Excludes one specific token (`0x44108f0223a3c3028f5fe7aec7f9bb2e66bef82f`) from calculations. Uses the `calculate_token_balance_changes` macro to compute net balance changes from inflows and outflows of tokens
- **Key fields**: `account_address` (treasury wallet), `token_address` (specific tokens held), `balance` (net change in token amount), `timestamp` (when balance change occurred)

### Component B: Cumulative balance calculation  
- **Purpose**: Converts balance changes into running cumulative balances over time
- **Logic**: Applies window functions to sum balance changes chronologically, partitioned by time grain, chain, account address, and token address. This creates a continuous time series showing total token holdings at each point in time
- **Key fields**: `balance` (cumulative sum of token holdings), partitioning by `timestamp_grain`, `chain_id`, `account_address`, `token_address`

### Component C: Data continuity and forward-filling
- **Purpose**: Ensures continuous time series data by filling gaps where no balance changes occurred  
- **Logic**: Uses the `fill_forward` macro to propagate the last known balance forward for periods with no transactions. This maintains accurate balance representation across all time periods
- **Key fields**: `balance` (forward-filled values), maintaining all dimension columns for proper time series continuity

### Component D: USD conversion
- **Purpose**: Converts token balances to USD amounts using daily price feeds
- **Logic**: Joins cumulative token balances with end-of-day price feeds by matching `timestamp`, `chain_id`, and `token_address`. Multiplies token balance by USD price using `safe_multiply`. Filters for positive balances only and daily price grain
- **Key fields**: `amount` (USD value calculated as balance × price), `price_usd` (end-of-day token price)

### Final aggregation
- **Combining components**: Sums USD amounts across all tokens held by the treasury address to get total treasury value
- **Currency conversion**: Uses end-of-day price feeds matched by date, chain, and token address for accurate USD conversion
- **Time aggregation**: Maintains daily time boundaries with forward-filling for missing periods
- **Final calculation**: The metric represents the total USD value of all tokens (excluding the specified excluded token) held in Across Protocol's treasury address at each point in time
