# vKAT KAT staked Methodology

## 1. Overview

KAT staked is defined as the total USD value of KAT assets locked within the vKAT voting escrow. The aggregate balance of KAT committed to the governance and voting escrow contract is represented by this metric, with assets held in the exit cooldown phase until official withdrawal is completed being included. Long-term economic alignment and governance commitment within the Katana ecosystem are quantified by tracking these locked balances over time.

## 2. Data sources

- **Blockchain events**: `Deposit` and `Withdraw` events from `VotingEscrow` contracts, covering Katana Chain
- **External data**: End-of-day price feeds for the KAT asset

## 3. Step-by-step calculation

### Component A: Lock event extraction

- **Purpose**: Extract deposit and withdraw actions from the voting escrow contract
- **Logic**: `Deposit` and `Withdraw` events are parsed from `VotingEscrow` contracts on Katana Chain. For each event, the transaction details, depositor account, token identifier, transaction amount, and the updated global locked balance are extracted. The transaction amount and the updated global locked balance are normalized by dividing the raw values by the asset's decimal precision.
- **Key fields**: `block_timestamp`, `amount`, `total_locked`

### Component B: Daily balance determination and forward-filling

- **Purpose**: Establish a continuous daily record of locked KAT balances
- **Logic**: The last updated global locked balance is selected for each day based on the latest block number and log index. A continuous daily date spine is generated from the first recorded event to the most recent day. For days without any deposit or withdraw activity, the last known global locked balance is carried forward to ensure a continuous daily balance series.
- **Key fields**: `timestamp`, `total_locked`, `kat_staked`

### Component C: USD conversion and final aggregation

- **Purpose**: Convert the daily locked KAT balances to USD and finalize the metric
- **Logic**: The daily locked KAT balances are multiplied by the end-of-day price of the KAT asset to determine the total USD value. The resulting values are aggregated by day, chain, and product dimensions. A final fill-forward strategy is applied to ensure no gaps exist in the daily time series, and a chain availability filter is applied to align the data with the active periods of the underlying network.
- **Key fields**: `timestamp`, `kat_staked`, `price_usd`
