SX Network vs Overtime Markets

SX Network (originally launched as SportX) was founded in 2019 by former trading floor professionals Andrew Young, Jake Hannah, and Julian Wilson in Toronto as a peer-to-peer Web3 betting exchange built to eliminate middleman margins and limit restrictions.

Operating as an EVM-compatible Layer-2 application chain leveraging Arbitrum Orbit and Polygon technologies, SX Network provides custom sports orderbook infrastructure, non-custodial smart-contract escrow settlement, and native cross-chain wagering capability.

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.
