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 Fees Methodology

## 1. Overview

Acala fees represents the total fees generated across the Acala ecosystem, including Layer 1 transaction fees, Layer 2 EVM fees, DEX trading fees, and treasury net deposits. This metric captures the total fee revenue generated by the Acala protocol from all its major components: the parachain layer, EVM compatibility layer, decentralized exchange, and treasury operations.

## 2. Data sources

- **Acala blockchain events**: Parsed event logs from the Acala parachain including `TransactionFeePaid` events for L1 fees, `Swap` events from the DEX pallet, and balance `Withdraw`/`Deposit` events for L2 EVM fees
- **Acala API endpoints**: Specialized endpoints providing liquid staking metrics including `homa.totalStakingBonded` for total staked DOT, `homa.toBondPool` for pending DOT stakes, tokens totalIssuance for LDOT supply, and `homa.totalVoidLiquid` for void LDOT amounts  
- **End-of-day price feeds**: Token price data from CoinGecko for USD conversion of ACA, DOT, and other supported tokens
- **Token metadata**: Internal token registry mapping Acala's internal token representations to symbols, decimals, and CoinGecko identifiers
- **Account mappings**: Relationships between Acala parachain accounts and EVM addresses for proper fee attribution

## 3. Step-by-step calculation

### Component A: Layer 1 chain fees
- **Purpose**: Calculates transaction fees paid on the Acala parachain layer
- **Logic**: Extracts `TransactionFeePaid` events from successful transactions, summing the base `amount` and `tip` components. Raw amounts are converted from the native 1e12 decimal format to ACA token units, then aggregated daily by product (acala for L1 fees)
- **Key fields**: `amount` (base transaction fee), `tip` (priority fee), both converted from raw blockchain decimals

### Component B: Layer 2 EVM fees  
- **Purpose**: Captures fees from EVM-compatible transactions on Acala
- **Logic**: Identifies EVM transactions through `Executed` events, then matches corresponding balance `Withdraw` and `Deposit` events using account mappings between parachain and EVM addresses. Calculates net fee by summing withdrawals and subtracting deposits, ensuring proper attribution to the transaction signer
- **Key fields**: `transaction_fee` (net balance change from EVM operations), `signer_address` (mapped between EVM and parachain formats)

### Component C: DEX trading fees
- **Purpose**: Calculates fees generated from trading activity on Acala's decentralized exchange
- **Logic**: Extracts `Swap` events from the DEX pallet, parsing token input/output amounts and addresses. Maps internal token representations to symbols and applies decimal conversions. For LDOT tokens, applies exchange rate conversion to underlying DOT value using the ratio of (total DOT staked + DOT in bond pool) / (total LDOT issued + void LDOT). Converts token amounts to USD using end-of-day price feeds, then applies 0.3% fee rate to calculate trading fees
- **Key fields**: `amount_in` and `amount_out` (swap amounts), `asset_in` and `asset_out` (token symbols), `ldot_exchange_rate` (DOT backing per LDOT)

### Component D: LDOT exchange rate calculation
- **Purpose**: Determines the DOT backing per LDOT token for accurate fee calculations
- **Logic**: Aggregates total DOT backing the liquid staking system by summing DOT already staked (from `totalStakingBonded` endpoint) and DOT waiting to be staked (from `toBondPool` endpoint). Calculates total effective LDOT supply by summing total issuance and void LDOT amounts. The exchange rate is the ratio of total DOT backing to effective LDOT supply
- **Key fields**: `total_staking` (DOT staked), `to_bond_pool` (pending DOT), `total_issuance` (LDOT supply), `void_ldot` (void LDOT amount)

### Component E: Treasury net deposits
- **Purpose**: Includes treasury deposits as a fee component
- **Logic**: References treasury net deposit data and treats these amounts as fees (specific calculation logic not visible in provided models)
- **Key fields**: `net_deposits` (treasury deposit amounts)

### Final aggregation
- **Combining components**: All fee components (L1 fees, L2 fees, DEX fees, treasury deposits) are combined using union operations, maintaining daily timestamp alignment and consistent field naming (`fees` column)
- **Currency conversion**: Each component is converted to USD using end-of-day CoinGecko prices matched by timestamp and token identifier before aggregation
- **Time aggregation**: All data is aggregated to daily boundaries using timestamp truncation, with consistent `timestamp_grain` of 'day'
- **Final calculation**: The total fees metric represents the sum of all USD-denominated fee components across Acala's ecosystem, processed through a finalization macro that applies zero-filling for missing data points and chain availability filtering
