For research purposes, Overtime fits the broad category of onchain automated-market-maker sportsbook and short-duration options venue. The launch facts connect it with binary, categorical, and scalar formats across Base, Arbitrum, and Optimism, while leaving many operating details unresolved. A live label was observed for this launch review, subject to product, jurisdiction, and maintenance changes. The retained research status reads "live": Official site and documentation describe current betting, supported networks, AMM pricing, collateral, and automated settlement.

The authoritative next step is https://www.overtimemarkets.xyz/. Check that Overtime's branding, legal entity, documentation, and support channels agree before treating the domain as operational. The claims below remain limited to what the cited material supports.

The comparison boundary for Overtime is explicit: binary, categorical, and scalar describes listed formats, sportsbook describes the mechanism field, and Base, Arbitrum, and Optimism describes network context. Other product attributes remain open questions. Readers should preserve that distinction when comparing the venue with alternatives.

Public source material supplies some access detail for Overtime; those rules can vary by product and can change after this review date. Research summary: Official site claims no geoblocking; users remain responsible for applicable law.

Treat "live" as historical classification for Overtime. Review the latest terms, prohibited jurisdictions, and onboarding screens before assuming access. KYC summary: No registration or KYC is required for wallet users according to the official site.

Overtime's structured mechanism field reads sportsbook; its outcome field reads binary, categorical, and scalar. Readers should not infer settlement authority, liquidity, or matching behavior beyond those literal labels.

Resolution risk at Overtime can dominate price analysis. Confirm what happens after ambiguous evidence, delayed events, data revisions, cancellations, or an unavailable oracle. Settlement and resolution summary: Chainlink nodes and designated providers supply final settlement data. Most sports markets settle automatically in about 15 minutes; niche markets can require manual review.

Overtime publishes or documents some economic terms; they should be rechecked in the interface because schedules and market-level parameters can change. Retained fee evidence: Sports AMM applies a current 2% protocol fee over oracle-fed odds. Users may pay network gas; social/email-login gas can be sponsored. Speed Markets have additional maturity-dependent LP fees.

Overtime has a researched money-flow description, while implementation details and supported onboarding routes may still differ. Retained custody evidence: Non-custodial smart-contract execution; wallet funds are committed directly to onchain positions and payouts are not centrally approved.

Overtime carries the ordinary risk of losing the amount committed, plus liquidity, slippage, rule-interpretation, operational, phishing, and regulatory risks. Its live status hint adds no assurance about solvency or continuity. Documented limitations include: Oracle/provider result is final, AMM risk limits can stop one-sided liquidity, and Speed products add high LP fees and liquidation-like payoff risk.

Evaluate Overtime by checking https://www.overtimemarkets.xyz/, recording the review date, and testing unfamiliar workflows with minimal value. If a material term is missing or contradictory, do not fill the gap with an assumption. Priority evaluation checks include: Confirm product is sports or Speed Market, Preview protocol, LP, and gas fees, Check network and collateral, and Read grading source and market rules.
