How Overtime Works

At its core, Overtime operates through a Pool-vs-Peer liquidity layer supported by a custom Automated Market Maker (AMM). This AMM continuously provides pricing and liquidity across thousands of active sports markets at any given moment, using odds oracles for real-time pricing and per-market open interest caps to manage risk effectively.

The Overtime protocol supports a comprehensive set of market types:

• Singles

• Parlays

• Same-Game Parlays (SGPs)

• Live Markets

• Futures

• Player Props

Overtime’s architecture uniquely supports thousands of live sports and esports markets every day, all composable into multi-leg parlays and leveraged payout structures. No other onchain prediction market currently matches this level of product depth or scalability. It enables a complete sportsbook experience that runs entirely onchain. Unlike centralized sportsbooks, every transaction, market creation, and settlement occurs transparently via smart contracts, ensuring full composability within the DeFi ecosystem.

Overtime is currently deployed across major Layer 2 networks of Optimism, Arbitrum, and Base, ensuring fast, low-cost, and scalable access for users across the Ethereum ecosystem.

Liquidity within Overtime is sourced from third-party liquidity providers (LPs) who deposit USDC, ETH, wBTC or cbBTC into open liquidity pools. These assets fund the AMM and back the markets, allowing LPs to take the position of “the house” and earn returns based on Overtime’s aggregate trading performance. This unique Pool-vs-Peer model effectively makes Overtime a decentralized market operator, a middle layer between traders and liquidity providers, eliminating the need for centralized intermediaries.

In addition to its full-featured onchain sportsbook dApp designed for traders, Overtime also provides a developer API that allows builders to directly integrate with its AMM and liquidity layer. This enables third-party applications, wallets, AI agents, aggregators or analytics platforms to create custom user experiences or new trading interfaces while leveraging Overtime’s existing market infrastructure and liquidity layer.
