# Kilt Average transaction fee Methodology

## 1. Overview

Average transaction fee measures the average fee users pay per transaction on Kilt Chain. It reflects the typical cost associated with utilizing the network for identity and credentialing services. This metric is used to evaluate the economic barrier to entry and the cost-efficiency of the protocol compared to other blockchain networks.

## 2. Data sources

- **Blockchain events**: `TransactionFeePaid` events and extrinsic records from Kilt Chain
- **External data**: End-of-day price feeds for the Kilt native asset

## 3. Step-by-step calculation

### Component A: Transaction fee extraction

- **Purpose**: Capture the total fee components paid for network interactions
- **Logic**: Successful `TransactionFeePaid` events are parsed from Kilt Chain records. The base fee amount and any additional tips are extracted from the event data. These components are summed to determine the total fee per transaction. All values are normalized by a decimal precision factor of 15.
- **Key fields**: `amount`, `tip`, `extrinsic_hash`

### Component B: Transaction volume calculation

- **Purpose**: Determine the total number of transactions processed by the network
- **Logic**: Successful extrinsics are aggregated on a daily basis. Unique extrinsic identifiers are counted to establish the total daily transaction volume.
- **Key fields**: `extrinsic_id`, `block_timestamp`

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

- **Purpose**: Derive the mean transaction cost and normalize the value to USD
- **Logic**: The total daily fee volume is divided by the total daily transaction count to calculate the average fee per transaction. This daily average is then multiplied by end-of-day price feeds to convert the value into USD. Data is finalized with daily granularity using UTC day boundaries.
