| TIP-239 | Same Game Parlays framework | Draft | Danijel | Add SGP framework to Overtime | Discord | 2025-02-04 |
This TIP proposes a framework to add Same Game Parlays as supported betting option on Overtime
Same Game Parlays (SGPs) have become a staple in traditional sportsbooks, driving engagement and betting volume. However, decentralized sportsbooks lack this feature, creating a competitive gap.
Integrating SGPs will:
- Enhance user engagement by allowing bettors to customize high-reward wagers within a single event.
- Expand market appeal to both casual and experienced bettors.
- Increase betting volume and liquidity, strengthening the platform.
- Match industry standards, keeping pace with traditional sportsbooks.
- Leverage smart contracts for transparent and automated bet settlement.
Our data partners support fetching SGP quotes from a handfull of sportsbooks, so we aim to leverage that feature to make Overtime more competitive and stand out.
The framework will use much of existing architecture, including the approach we use for Live Betting and the normal parlays architecture for Risk Management.
It will be a two step approach using Chainlink nodes to validate quotes for SGPs and execute a trade.
The workflow is as follows:
- The user signals a potential SGP trade to SGPTradingProcessor contract by sending the SGP ticket details.
- The SGPTradingProcessor relays the request to the Chainlink Node
- The Chainlink Node invokes our supported data partners to receive quotes on the requested SGP. Currently supported sportbooks from which the quote can be fetched include DraftKings, BetMGM and BlueBook (formerly known as FanDuel)
- The Chainlink Node specific configuration on which sportsbooks it will use, and how it will apply additional fees or aggregation will be subject to pDAOs management.
- If the node approves the SGP trade, it executes a transaction on behalf of the user which verifies and writes the bet onchain.
In case any of the legs of the SGP are cancelled and there are no lost legs, the whole ticket is cancelled.
pDAO will be able to fine adjust limits, fees and all other risk parameters regarding SGP framework on its discretion.
Introducing Same Game Parlays (SGPs) aligns with Overtime’s goal of offering a competitive and engaging betting experience. SGPs allow users to combine multiple bets within a single event, creating higher-reward opportunities while increasing platform activity. By leveraging smart contracts, Overtime can ensure seamless settlement and transparency, differentiating itself from centralized sportsbooks. Implementing SGPs also strengthens liquidity and positions Overtime as a more versatile decentralized betting platform.
