# Acala Network Transaction count Methodology

## 1. Overview

Transaction count measures the total number of unique transactions processed daily on the Acala blockchain ecosystem. This metric captures both native Substrate transactions and Ethereum-compatible transactions executed through Acala's EVM+ environment, providing a comprehensive view of blockchain activity across Acala's dual-execution model.

## 2. Data sources

The calculation uses these primary data sources:
- **Acala blockchain extrinsics**: Native Substrate transactions containing standard blockchain operations and parachain-specific functionality
- **Acala blockchain events**: Blockchain events generated by transaction execution, specifically filtered for EVM execution events from the `evm` pallet
- **Chain availability configuration**: Configuration data that determines which blockchain networks should be included in the final metric output

## 3. Step-by-step calculation

### Component A: Transaction data unification
- **Purpose**: Combines native Substrate transactions and EVM transactions into a unified transaction dataset
- **Logic**: Takes native Acala extrinsics using their original `extrinsic_id` as unique identifiers, and combines them with EVM execution events where each event gets a composite identifier formed by concatenating `extrinsic_id` and `event_index`. EVM events are filtered to only include events where the `event_pallet` is `evm` and `event_method` is `Executed`, indicating successful EVM transaction execution. Native transactions are labeled with chain ID `acala` while EVM transactions are labeled as `Acala EVM`
- **Key fields**: `block_timestamp` for timing, `extrinsic_id` for native transaction identification, composite `extrinsic_id-event_index` for EVM transaction identification, and `chain_id` for network categorization

### Component B: Daily aggregation
- **Purpose**: Aggregates the unified transaction data into daily totals with proper business categorization
- **Logic**: Groups transactions by day using timestamp truncation to day boundaries, counts approximate distinct transaction identifiers per day using `approx_count_distinct` for performance optimization. Applies standard Token Terminal business categorization by setting `market_sector_id` to `blockchains_l2` and `business_segment_id` to `blockchain`. Sets `product_id` to null as this metric applies to the entire blockchain rather than specific products
- **Key fields**: `timestamp` truncated to day grain, `transaction_count` as the aggregated distinct count, business classification fields for categorization

### Final aggregation
- **Combining components**: The daily aggregated data is processed through Token Terminal's standard metric finalization macro which validates the schema, ensures consistent field types, and applies gap-filling logic
- **Currency conversion**: Not applicable for transaction count metrics
- **Time aggregation**: Data is aggregated to daily boundaries with incremental processing that includes a configurable lookback window to handle late-arriving data
- **Final calculation**: The final metric represents the total number of unique transactions per day across both native Substrate and EVM execution environments, with a fill-zeros strategy applied to ensure continuous daily values even when no transactions occur. A final chain availability filter is applied to include only networks that meet Token Terminal's availability criteria
