# Injective Cosmos Median transaction fee Methodology

## 1. Overview

Median transaction fee measures the median fee paid across all transactions on Injective Cosmos. It represents the cost of a typical user interaction, providing a representative view of network affordability that is not skewed by exceptionally high or low values. This metric is essential for assessing the economic barrier to entry and the cost-efficiency of the Injective Cosmos ecosystem for daily users.

## 2. Data sources

- **Blockchain events**: Transaction metadata from Injective Cosmos
- **External data**: End-of-day price feeds for the native INJ asset

## 3. Step-by-step calculation

### Component A: Transaction fee extraction

- **Purpose**: Capture raw fee data from all transactions processed on the network.
- **Logic**: Fees are extracted from transaction metadata on Injective Cosmos. Regular expressions are used to parse the transaction fee strings, separating the raw numerical quantity from the associated asset unit. Transactions with null fee values are excluded from the calculation.
- **Key fields**: `transaction_fee`, `block_timestamp`, and `transaction_hash`.

### Component B: USD normalization

- **Purpose**: Convert native fee amounts into a standardized USD value for comparison.
- **Logic**: Raw fee amounts are normalized by decimal precision. These normalized values are then multiplied by the end-of-day price of the native asset to determine the fee in USD.
- **Key fields**: `price` and `transaction_fee`.

### Component C: Median aggregation

- **Purpose**: Calculate the daily representative fee value.
- **Logic**: Transactions are grouped into 24-hour periods using UTC day boundaries. Within each daily group, a quantile function is applied to all USD-denominated fees to identify the 50th percentile (median). This methodology ensures that the final value reflects the cost paid by a typical user rather than a simple average. The resulting dataset is zero-filled for any days where no transaction activity is recorded.

Validators process transactions and receive transactions fees (supply-side fees).

Injective is a smart contract platform for decentralized finance applications (a blockchain) and an orderbook exchange protocol. Injective was founded by Eric Chen, Albert Chon etc. and launched in 2020. Note that this dashboard only tracks Injective's blockchain business.

INJ holders own and govern the protocol. They currently take a cut of the total transaction fees paid by users (revenue) via Burn Auctions. Injective's investors include Binance, Jump Crypto, Mark Cuban, etc.
