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 Revenue Methodology

## 1. Overview

Revenue is measured as the portion of fees retained by Katana, representing 100% of the generated fees due to the absence of supply-side payouts. Earnings are accumulated across multiple protocol products, including Katana Chain, Katana Perps, Katana Vault Bridge, Katana AUSD Yield, and vKAT. These streams are derived from network gas fees, perpetual trading fees, vault yield harvests, treasury yield shares, early-exit penalties, and third-party voting incentives. All collected amounts are normalized by decimal precision and converted to USD using end-of-day price feeds.

## 2. Data sources

- **Blockchain events**: `TradeExecuted` events from `Exchange` contracts, `YieldCollected` events from `vbUSDC`, `vbUSDT`, `vbETH`, `vbWBTC`, and `vbUSDS` contracts, `Exit` events from `DynamicExitQueue` contracts, `NewCampaign` events from `DistributionCreator` contracts, ERC-20 token transfers, and transaction gas data, covering Katana Chain and Ethereum
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Katana Chain gas fee calculation

- **Purpose**: Capture gas fees generated from transactions on Katana Chain
- **Logic**: Transaction data is parsed to calculate L2 execution fees, L1 settlement fees, and Isthmus operator fees. L2 gas fees are calculated by multiplying the gas used by the gas price, with the result normalized by decimal precision. L1 gas fees are calculated using the L1 fee, or by multiplying L1 gas used, L1 gas price, and the L1 fee scalar, with the result normalized by decimal precision. Isthmus operator fees are calculated by adding the operator fee constant to the product of gas used and the operator fee scalar divided by one million, with the result normalized by decimal precision. These three components are summed to determine the total gas fees.
- **Key fields**: `gas_used`, `gas_price`, `l1_fee`, `l1_gas_used`, `l1_gas_price`, `l1_fee_scalar`, `operator_fee_constant`, `operator_fee_scalar`

### Component B: Katana Perps trading fee calculation

- **Purpose**: Capture trading fees from perpetual contract executions
- **Logic**: `TradeExecuted` events from V1 and V2 `Exchange` contracts are parsed. Maker fees and taker fees are extracted from the `makerFeeQuantity` and `takerFeeQuantity` fields, respectively. These fees are normalized by decimal precision and summed to calculate the total perpetual trading fees.
- **Key fields**: `makerFeeQuantity`, `takerFeeQuantity`

### Component C: Katana Vault Bridge yield calculation

- **Purpose**: Capture yield harvested from the vault bridge contracts
- **Logic**: `YieldCollected` events are parsed from `vbUSDC`, `vbUSDT`, `vbETH`, `vbWBTC`, and `vbUSDS` contracts. The harvested yield amounts are extracted from the `vbTokenAmount` field. These amounts are normalized by decimal precision based on the underlying asset's decimals.
- **Key fields**: `vbTokenAmount`, `token_address`

### Component D: Katana AUSD Yield calculation

- **Purpose**: Capture Agora T-bill yield share transferred to the Katana-controlled Safe
- **Logic**: ERC-20 token transfers of Agora AUSD to the designated Katana-controlled Safe address are filtered and aggregated. Only transfers that are not marked as removed are included. The transfer values are normalized by decimal precision.
- **Key fields**: `value`, `to_address`, `token_address`

### Component E: vKAT exit fees and voting incentives calculation

- **Purpose**: Capture early-exit penalties and third-party voting incentives associated with vKAT
- **Logic**: Early-exit fees are extracted from `Exit` events emitted by `DynamicExitQueue` contracts, where the fee amount is normalized by decimal precision. Third-party voting incentives are extracted from `NewCampaign` events emitted by `DistributionCreator` contracts, with campaigns filtered for campaign type 102. Campaigns funded by the Katana DAO or its yield Safe are excluded to prevent double-counting. The remaining reward amounts are normalized by decimal precision.
- **Key fields**: `fee`, `campaignType`, `creator`, `amount`

### Component F: USD conversion and revenue aggregation

- **Purpose**: Normalize all product fees to USD and aggregate them as protocol revenue
- **Logic**: Daily fee amounts for each product are multiplied by end-of-day asset prices to convert them to USD. Because the protocol take rate is 100% across all products, total revenue is set equal to the sum of these USD-denominated fees. The final revenue metrics are aggregated daily using UTC boundaries, with missing days filled with zeros.
- **Key fields**: `fees`, `price_usd`
