Players wager against the house (liquidity provided by BetSwirl or their partners) in randomized games of chance, such as coin tosses or dice rolls.

Betswirl is a non-custodial betting platform built on Polygon, BNB Chain, and Avalanche. BetSwirl was co-founded by Romuald Hog and Nato, and was launched in March 2022.

The BetSwirl team own and govern the protocol. They and BETS holders currently receive all fees paid by players (revenue).

# BetSwirl Trading volume Methodology

## 1. Overview

Betswirl trading volume measures the total USD value of betting activity across all Betswirl prediction market games. This metric captures the volume of bets placed by users across multiple game types (CoinToss, Dice, Roulette, Keno, and Russian Roulette) on four blockchain networks (Arbitrum, BSC, Polygon, and Avalanche). The calculation aggregates daily betting volumes from blockchain events, handles multi-player game mechanics, and converts all amounts to USD using end-of-day price feeds.

## 2. Data sources

- **Betting events**: Parsed `Roll` events from Betswirl game contracts including CoinToss, Dice, Roulette, and Keno games across Arbitrum, BSC, Polygon, and Avalanche networks
- **Russian Roulette events**: Parsed `Roll` events from Russian Roulette contracts with multi-seat betting mechanics across all supported chains  
- **Blockchain transaction data**: Transaction timestamps, hashes, and log indices from Arbitrum, BSC, Polygon, and Avalanche networks
- **Token price data**: End-of-day token price feeds for USD conversion across all supported networks
- **Token metadata**: Token symbols, decimal places, and contract addresses for proper amount calculation
- **Wrapped token mappings**: Native token to wrapped token address mappings (ETH to WETH, BNB to WBNB, AVAX to WAVAX, MATIC to WMATIC)
- **Cross-chain pricing**: BETS token pricing from Polygon network used for Arbitrum BETS tokens due to liquidity differences

## 3. Step-by-step calculation

### Component A: Standard betting event collection
- **Purpose**: Collects betting volumes from standard Betswirl games (CoinToss, Dice, Roulette, Keno)
- **Logic**: Extracts `Roll` events from multiple game contract versions across all supported chains. Events contain the betting token address (`token`) and bet amount (`amount`) fields. Each event represents a single betting transaction. The system processes events from five protocol versions (v1-v5) with different game availability per version and chain. Events are classified with business metadata including chain, version, game type, and categorized under prediction markets business line and betting segment.
- **Key fields**: Block timestamp for daily aggregation, transaction hash and log index for uniqueness, `token` for token identification, `amount` for bet size, derived chain and version information

### Component B: Russian roulette event processing  
- **Purpose**: Handles multi-player Russian Roulette betting mechanics where multiple users can participate in a single round
- **Logic**: Processes `Roll` events from Russian Roulette contracts containing a `seats` array representing all participating players and their bet amounts (`betAmount`). The system unnests the seats array to create individual records per participant, then groups by round to calculate total volume. For each unique combination of timestamp, transaction, game round, and token, the calculation multiplies the per-seat bet amount by the number of participating seats to determine the full round volume.
- **Key fields**: Block timestamp for aggregation, `seats` array for player participation, `betAmount` for individual bet size, `token` for token identification

### Component C: Token address normalization
- **Purpose**: Standardizes token addresses for consistent pricing and eliminates cross-chain pricing inconsistencies  
- **Logic**: Replaces null addresses (representing native tokens like ETH, BNB, AVAX, MATIC) with their corresponding wrapped token addresses for accurate price lookups. Implements special handling for BETS token on Arbitrum by using the Polygon BETS token address for pricing due to higher liquidity on Polygon. The mapping ensures all tokens can be properly priced using available price feeds.
- **Key fields**: Original `token_address` field mapped to standardized addresses, `chain` field to determine appropriate wrapped token, `real_chain` field to preserve original chain information

### Component D: Daily aggregation
- **Purpose**: Combines all betting events into daily trading volume totals by relevant dimensions
- **Logic**: Aggregates betting amounts from both standard games and Russian Roulette on a daily basis using timestamp truncation. Groups data by date, chain, protocol version, contract name, account name, and token address. For Russian Roulette, this includes the pre-calculated seat-multiplied amounts. The aggregation sums all betting activity to produce daily volume totals for each unique combination of dimensions.
- **Key fields**: Truncated `timestamp` for daily boundaries, `amount` for volume summation, dimensional fields for grouping

### Final aggregation  
- **Combining components**: Standard betting events and Russian Roulette volumes are combined through union operations, then aggregated by day and dimensional attributes to create comprehensive daily trading volumes
- **Currency conversion**: Applies decimal correction based on token metadata, then converts all amounts to USD using end-of-day price feeds matched by date, chain, and token address
- **Time aggregation**: Uses daily timestamp truncation with zero-filling for missing dates to ensure continuous time series data
- **Final calculation**: The final trading volume represents the sum of all betting amounts in USD for each day, properly accounting for token decimals, multi-player game mechanics, and cross-chain token pricing adjustments
