# Ajuna Substrate Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the average fee users pay per transaction on Ajuna Substrate. It reflects the typical cost associated with executing operations on the network. This metric serves as a key indicator of network affordability and resource pricing for users interacting with Ajuna Substrate.

## 2. Data sources

- **Blockchain events**: `TransactionFeePaid` events and extrinsic data from Ajuna Substrate
- **External data**: End-of-day price feeds for native assets

## 3. Step-by-step calculation

### Component A: Ajuna Substrate fee extraction

- **Purpose**: Capture the total value of fees paid by users for successful transactions.
- **Logic**: `TransactionFeePaid` events are parsed from the Ajuna Substrate chain. For each event, both the base fee amount and the tip (priority fee) are extracted from the event data. These values are summed to determine the total fee per successful extrinsic. Amounts are normalized by decimal precision.
- **Key fields**: `amount`, `tip`, `extrinsic_hash`

### Component B: Transaction activity monitoring

- **Purpose**: Quantify the total number of distinct transactions processed by the network.
- **Logic**: Transaction counts are derived by aggregating unique extrinsic identifiers from Ajuna Substrate. Only extrinsics recorded on-chain are included in the daily count to ensure parity with the captured fee events.
- **Key fields**: `extrinsic_id`, `block_timestamp`

### Component C: Average fee derivation and USD conversion

- **Purpose**: Calculate the mean cost per transaction and normalize the value to USD.
- **Logic**: Total daily fees are divided by the total daily transaction count to produce the average transaction fee in native units. This result is multiplied by end-of-day asset prices to convert the metric into USD. Calculations are performed at a daily granularity using UTC day boundaries. Any days with missing data are filled with zeros to ensure a continuous time series.
