The network uses pessimistic proofs via the AgglayerGateway for settlement on Ethereum, with vault bridges for cross-chain asset transfers.

Katana Network provides a scalable execution environment connected to Ethereum through the Agglayer interoperability layer.

Katana Network is a Layer 2 blockchain built on the Agglayer ecosystem.

# Katana KAT staked Methodology

## 1. Overview

KAT staked is measured as the total USD value of KAT assets locked within the vKAT voting escrow contract. The long-term economic commitment of participants to the Katana ecosystem is represented by this metric, as locked KAT assets grant voting power and governance rights through the vKAT product. Assets held in the exit cooldown period are included in this metric until they are officially withdrawn.

## 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 flow extraction

- **Purpose**: Extract deposit and withdraw actions to track the total balance of locked KAT.
- **Logic**: `Deposit` and `Withdraw` events are parsed from `VotingEscrow` contracts. For each event, the transaction details, depositor account, token ID, and transaction value are extracted. The global locked balance of the escrow contract is captured from the `newTotalLocked` field. All asset amounts are normalized by decimal precision.
- **Key fields**: `value` (transaction amount), `newTotalLocked` (global escrow balance), `block_timestamp` (timing).

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

- **Purpose**: Establish a continuous daily record of the total locked KAT balance.
- **Logic**: The last recorded `newTotalLocked` value is selected for each day to represent that day's closing balance. A continuous daily date spine is generated starting from the initial lock event. For days without any deposit or withdraw activity, the last known locked balance is carried forward to ensure a complete daily time series.
- **Key fields**: `total_locked` (daily closing balance), `timestamp` (daily interval).

### Component C: USD conversion and finalization

- **Purpose**: Convert the daily locked KAT balances into USD values.
- **Logic**: The daily locked KAT balances are multiplied by the end-of-day price of the KAT asset. A final fill-forward strategy is applied to prevent any gaps in the daily time series, and chain availability filters are applied to align the data with platform freshness standards.
- **Key fields**: `kat_staked` (staked balance), `price_usd` (asset price).
