Overtime Markets vs Limitless Exchange

Overtime Markets was launched in 2022 by the Thales Core Council—a decentralized governance council elected by stakers of the Thales (later rebranded to OVER) protocol. Engineered as an on-chain, peer-to-contract sports betting protocol on Ethereum Layer-2 networks (Optimism and Arbitrum), Overtime eliminated traditional sportsbook frictions such as forced identity verification (KYC), account limits on winning traders, and centralized custody. Instead of matching order books or taking counterparty risk, Overtime utilizes an Automated Market Maker (AMM) architecture derived from binary option mechanics.

To establish fair market pricing without a centralized oddsmaker, Overtime routes real-time data feeds via Chainlink oracles that scrape benchmark odds from global market venues like Pinnacle. The protocol dynamically adjusts its odds using a dynamic "skew mechanism": when heavy capital flows onto one side of an outcome, the AMM automatically reduces payout odds for the backed side while boosting yields on the unbacked side. This incentivizes arbitrage traders to rebalance the protocol’s net exposure, protecting the vault liquidity pool from directional market risk.

Limitless Exchange was founded in late 2023 by CJ Hetherington, Rev Miller, Roman Mogylnyi, and Dima Horshkov to solve the core structural friction plaguing first-generation decentralized prediction platforms: slow settlement speeds, high gas costs, and poor liquidity for short-term events. Recognizing that platforms like Polymarket focused primarily on macro multi-month political events, the team engineered Limitless as a high-velocity protocol specifically optimized for micro-duration contracts—such as hourly crypto price brackets, daily equity moves, and real-time social metrics.

Built on Coinbase’s Ethereum Layer-2 network Base, Limitless pairs on-chain order execution with hybrid Central Limit Order Book (CLOB) architecture to eliminate automated market maker (AMM) slippage while preserving non-custodial wallet interaction. The protocol quickly attracted institutional backing, raising a $3 million pre-seed round led by 1confirmation alongside Coinbase Ventures, followed by a $4 million strategic round backed by Arthur Hayes’ Maelstrom fund and a major $10 million Series A expansion in late 2025. To further lower trading barriers, Limitless allows users to state arbitrary market conditions using natural language, which smart contracts automatically parse into tradable binary contracts.
