Liquidity providers deposit funds into Katana and receive trading fees from traders (supply-side fees).

Katana is a non-custodial exchange protocol built on Ronin. Katana was founded by Sky Mavis and launched in 2021.

The Ronin team own and govern the protocol. They currently take a cut of the total trading fees paid by traders (revenue).

# Katana Active users (daily) Methodology

## 1. Overview

Daily Active Users (DAU) for Katana measures the number of unique addresses that executed at least one trade on the Katana decentralized exchange in a given day. This metric tracks user engagement and trading activity on Katana, a DEX built on the Ronin blockchain. The calculation identifies distinct trader addresses per day based on their swap transaction activity.

## 2. Data sources

- **Ronin blockchain events**: Parsed `Pair_Swap` events from Katana v1 DEX smart contracts
- **Transaction data**: Ronin transaction records containing sender address metadata and transaction details
- **Blockchain event logs**: Raw event logs from Katana pair contracts capturing swap activities including token amounts and addresses
- **Transaction metadata**: Block timestamps, transaction hashes, and log indices for event tracking

## 3. Step-by-step calculation

### Component A: Trade event extraction
- **Purpose**: Identify all trading activity on Katana DEX by extracting swap events and linking them to user addresses
- **Logic**: Extract all `Pair_Swap` events from Katana v1 contracts on Ronin blockchain. Join these swap events with Ronin transaction records to obtain the `from_address` field, which represents the user who initiated each trade. Calculate the net token amounts involved in each swap by computing the difference between tokens coming in and going out (`amount0In` - `amount0Out` for the first token, `amount1In` - `amount1Out` for the second token). Apply incremental processing logic to only process recent transactions when updating the dataset, using a lookback period to ensure data consistency.
- **Key fields**: `block_timestamp` for timing, `from_address` as the trader identifier, `transaction_hash` and `log_index` for unique event identification, `amount0In`, `amount0Out`, `amount1In`, `amount1Out` for swap quantities

### Component B: Daily user aggregation
- **Purpose**: Count unique active traders per day by grouping trading activity into daily time periods
- **Logic**: Truncate block timestamps to daily granularity to group all trading activity by calendar day. Identify distinct user addresses within each day to count unique active traders. Label all identified users as 'Trader' type since this metric specifically tracks trading activity rather than other protocol interactions. Include metadata fields for business classification including market sector, business segment, and product categorization.
- **Key fields**: `timestamp` truncated to day, `user_address` for distinct counting, `user_type` set to 'Trader', `chain` set to 'ronin'

### Final aggregation
- **Combining components**: The daily aggregation component directly processes the trade event data without additional combining steps, as each swap event already represents one user's trading activity for a specific day
- **Currency conversion**: No currency conversion required as this metric counts users rather than monetary values
- **Time aggregation**: All timestamps are truncated to daily boundaries using day-level truncation, ensuring consistent daily counting periods
- **Final calculation**: The final DAU value for each day equals the count of distinct user addresses that executed at least one trade on that day, derived by selecting unique combinations of truncated timestamp and user address
