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 Methodology

## 1. Overview

The Across treasury metric measures the total USD value of tokens held in the protocol's treasury address at the end of each day. This metric provides insight into the protocol's financial reserves and asset management by tracking the cumulative value of all tokens stored in the designated treasury wallet on Ethereum. The calculation tracks token balance changes over time, converts them to USD values using end-of-day prices, and aggregates them into a single daily treasury value.

## 2. Data sources

- **Ethereum token transfer events**: Parsed `Transfer` events and transaction logs from Ethereum to track token movements into and out of the treasury address
- **Ethereum transaction traces**: Transaction data and event logs to capture all token balance changes affecting the treasury address
- **End-of-day token price feeds**: Daily USD price data for all tokens held in the treasury for accurate valuation
- **Token metadata**: Token contract information including decimal places and symbols for proper balance calculations

## 3. Step-by-step calculation

### Component A: Treasury balance tracking
- **Purpose**: Identifies and tracks all token balance changes for the Across treasury address
- **Logic**: Processes Ethereum blockchain data to calculate net balance changes for the treasury address `0xb524735356985d2f267fa010d681f061dff03715`. The system monitors all token movements (inflows and outflows) affecting this address by parsing `Transfer` events and transaction logs. Balance changes are calculated as the net effect of all transactions within each time period, accounting for both incoming and outgoing token transfers.
- **Key fields**: `timestamp` for when changes occurred, `account_address` for the treasury wallet, `token_address` for each token type, `balance` for the net change amount, and `token_symbol` for identification

### Component B: Cumulative balance calculation  
- **Purpose**: Converts balance changes into running cumulative balances over time
- **Logic**: Takes the balance changes from Component A and calculates cumulative running totals for each token held by the treasury. Uses window functions to sum all balance changes from the beginning of time up to each timestamp, partitioned by timestamp grain, chain, account address, and token address. This creates a complete historical view of token holdings at any point in time.
- **Key fields**: `balance` representing the cumulative token balance at each timestamp for each token type

### Component C: Data continuity and forward-filling
- **Purpose**: Ensures complete time series data by filling gaps in the historical record
- **Logic**: Applies forward-filling logic to handle days when no balance changes occurred for specific tokens. If a token balance remains unchanged on a given day (no transactions), the system carries forward the last known balance to maintain continuous daily records. This ensures every day has a complete snapshot of all token holdings.
- **Key fields**: `timestamp` for daily records, token identification fields, and forward-filled `balance` values

### Component D: USD conversion
- **Purpose**: Converts token balances to USD values for aggregation and reporting
- **Logic**: Joins the forward-filled token balances with end-of-day price feeds to calculate USD values. For each token balance on each day, multiplies the token amount by the corresponding daily USD price. Only includes balances greater than zero and uses daily price grain data. Filters out any tokens without available price data to ensure accurate valuation.
- **Key fields**: `amount` representing the USD value of each token holding, calculated as token balance multiplied by daily USD price

### Final aggregation
- **Combining components**: Sums all individual token USD values to calculate the total treasury value for each day
- **Currency conversion**: Uses end-of-day USD prices matched by timestamp, chain, and token address to ensure accurate daily valuations
- **Time aggregation**: Aggregates at daily boundaries based on timestamp grain, ensuring consistent daily reporting
- **Final calculation**: The treasury metric equals the sum of all token balances (in USD) held by the treasury address `0xb524735356985d2f267fa010d681f061dff03715` on Ethereum at the end of each day, with zero-filling applied for days with no holdings
