Collators aggregate parachain transactions block candidates and producing state transition proofs for validators based on those blocks.

Acala is a specialized stablecoin and liquidity blockchain powered by Polkadot Relay chain.

ACA holders own and govern the protocol. Acala’s investors include Pantera Capital, Coinbase Ventures, and Polychain Capital.

# Acala Network Revenue Methodology

## 1. Overview

Acala revenue represents the total daily USD value of fees and income generated by the Acala network ecosystem. This includes both transaction fees from the native Acala parachain and its EVM-compatible layer, as well as net treasury operations from Acala's liquid staking protocol. The metric captures protocol revenue from network usage fees and liquid staking treasury management activities.

## 2. Data sources

The calculation relies on several key data sources:
- **Acala blockchain events**: Native parachain event logs including transaction fee payments, token deposits/withdrawals, and EVM execution records
- **Acala staking data**: API endpoints providing total staked amounts, bond pool balances, LDOT token issuance, and void LDOT amounts
- **Account mapping data**: Parachain-to-EVM account relationships established through account claim events
- **Token metadata**: Token definitions including symbols, decimals, and asset identifiers for various token types
- **End-of-day price feeds**: CoinGecko API data for multiple tokens including ACA, DOT, LDOT, and other supported assets
- **Treasury account data**: Specific monitoring of treasury account `23M5ttkmR6Kco5p3LFGKMpMv4zvLkKdUQWW1wGGoV8zDX3am`

## 3. Step-by-step calculation

### Component A: Acala L1 chain fees
- **Purpose**: Captures transaction fees from native Acala parachain operations
- **Logic**: Extract `TransactionFeePaid` events from successful transactions on Acala blockchain. Sum the `amount` and `tip` fields from event data, normalize by dividing by 1e12 to account for ACA token decimals. Convert to USD using end-of-day ACA price from CoinGecko. Aggregate daily by truncating timestamps to day granularity.
- **Key fields**: `amount` (base transaction fee), `tip` (additional fee), `block_timestamp` (for daily aggregation)

### Component B: Acala EVM layer fees  
- **Purpose**: Captures transaction fees from EVM-compatible operations on Acala
- **Logic**: Identify EVM transactions through `Executed` events in the EVM pallet, then extract corresponding balance `Withdraw` and `Deposit` events from the same extrinsic. Match parachain signer addresses to EVM addresses using account claim mappings. Calculate net fee as withdrawals minus deposits, ensuring the signer of balance changes matches the EVM transaction signer. Normalize amounts by dividing by 1e12 and aggregate daily.
- **Key fields**: `transaction_fee` (net balance change), `signer_address` (account performing transaction), `extrinsic_id` (linking events)

### Component C: LDOT exchange rate calculation
- **Purpose**: Determines the DOT-to-LDOT exchange rate for treasury value calculations
- **Logic**: Calculate total underlying DOT backing the LDOT system by summing total staked DOT amounts and DOT waiting in bond pools. Calculate total effective LDOT supply by summing total issuance and void LDOT amounts. Both DOT and LDOT amounts are normalized by dividing by 1e10. The exchange rate equals total DOT divided by total LDOT supply.
- **Key fields**: `total_staking` (staked DOT), `to_bond_pool` (unstaked DOT), `total_issuance` (LDOT supply), `void_ldot` (burned LDOT)

### Component D: Treasury deposits and withdrawals
- **Purpose**: Tracks value flows into and out of Acala's liquid staking treasury
- **Logic**: Extract `Deposited` and `Withdrawn` token events specifically for the treasury account. Parse complex token structures to identify token types including native tokens, liquid crowdloan tokens, foreign assets, and ERC20 tokens. Map token symbols to CoinGecko IDs using predefined mappings. Convert amounts to decimal form using token-specific decimals, then convert to USD using end-of-day price feeds. Apply LDOT exchange rate adjustments to account for the underlying value relationship.
- **Key fields**: `amount` (token quantity), `token` (complex token identifier), `account` (treasury address filter)

### Final aggregation
- **Combining components**: Union L1 chain fees, L2 EVM fees, and net treasury operations (deposits minus withdrawals) into a single revenue stream. L1 and L2 fees are categorized under product IDs `acala` and `Acala EVM` respectively, while treasury operations use product ID `Acala Liquid Staking`.
- **Currency conversion**: All components are converted to USD using end-of-day price feeds from CoinGecko, with specific token mappings maintained for accurate pricing of different asset types.
- **Time aggregation**: All data is aggregated to daily boundaries using timestamp truncation, with revenue summed across all transactions and operations within each day.
- **Final calculation**: The `finalize_metric_revenue` macro applies standardized formatting, applies a fill-zeros strategy for missing days, and includes chain availability filtering to ensure data quality and consistency across the time series.
