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 Trading volume Methodology

## 1. Overview

Katana trading volume measures the total USD value of tokens traded on the Katana decentralized exchange (DEX) on the Ronin blockchain. This metric captures all swap activity on Katana's automated market maker (AMM), providing insight into the exchange's liquidity utilization and user activity. The calculation aggregates individual swap events, applies decimal corrections and USD conversion, and includes anti-manipulation measures to ensure accurate volume reporting.

## 2. Data sources

The calculation uses several key data sources:

- **Katana swap events**: Parsed `Swap` events from Katana v1 DEX smart contracts on Ronin blockchain, containing token amounts in and out for each trade
- **Katana pair creation events**: `PairCreated` events from Katana's factory contract, defining valid trading pairs and their configurations
- **Ronin transaction data**: Transaction records providing user addresses and transaction context for each swap
- **End-of-day price feeds**: Daily token price data in USD for accurate value conversion
- **Token metadata registry**: Standard token information including symbols, names, and decimal precision
- **Manual token configurations**: Katana-specific token metadata for tokens not available in the standard registry, such as Smooth Love Potion (SLP)

## 3. Step-by-step calculation

### Component A: Trade event extraction
- **Purpose**: Extract and process individual swap events from Katana DEX
- **Logic**: Collect all `Swap` events from Katana v1 pair contracts on Ronin blockchain. For each swap, calculate the net change in both tokens by subtracting the `amount0Out` from `amount0In` for token0, and `amount1Out` from `amount1In` for token1. Join with transaction data to obtain the user address (`from_address`) for each trade. Each swap event includes the pair contract address, transaction hash, log index, and block timestamp for unique identification.
- **Key fields**: `block_timestamp`, `transaction_hash`, `log_index`, `address` (pair contract), `user_address`, `token0_amount`, `token1_amount`

### Component B: Trading pair metadata
- **Purpose**: Define valid trading pairs and their token configurations
- **Logic**: Extract trading pair information from `PairCreated` events in Katana's factory contract. Each pair creation event defines a unique trading pair with two token addresses (`token0` and `token1`) and the pair contract address. Join with token metadata to obtain decimal precision and symbols for each token. Apply manual token configurations for Katana-specific tokens like SLP that may not exist in the standard token registry. Generate descriptive pair names by concatenating token symbols (e.g., "SLP-WETH"). Set fee tiers at 0.3% (3000 basis points) for all Katana v1 pairs.
- **Key fields**: `account_address` (pair contract), `token0_address`, `token1_address`, `token0_decimals`, `token1_decimals`, `account_name`, `fee_tier`

### Component C: Volume calculation and USD conversion
- **Purpose**: Calculate daily trading volumes in USD with anti-manipulation measures
- **Logic**: Join swap events with trading pair metadata to obtain token decimal precision. Apply decimal correction by dividing the absolute value of each token amount by 10 raised to the power of that token's decimals. Convert corrected token amounts to USD by joining with end-of-day price feeds for both tokens in the pair. Apply anti-manipulation filtering by taking the minimum USD value between the two tokens in each swap - this prevents inflated volumes from price manipulation or oracle attacks. Aggregate volumes daily by truncating timestamps to day boundaries and summing all swap volumes.
- **Key fields**: `timestamp` (daily), `trading_volume` (USD), `token0_amount` (decimal-corrected), `token1_amount` (decimal-corrected)

### Final aggregation
- **Combining components**: Sum all daily trading volumes across all Katana trading pairs to get total platform volume
- **Currency conversion**: Use end-of-day token prices joined by timestamp, token address, and chain to convert token amounts to USD values
- **Time aggregation**: Truncate all swap timestamps to day boundaries and group by daily periods
- **Final calculation**: The final trading volume is the sum of all individual swap volumes in USD, where each swap volume equals the minimum USD value between the two tokens involved in that swap, ensuring protection against price manipulation while capturing genuine trading activity
