The details, with sources

Availability
Live on-chain sportsbook on Optimism, Arbitrum and Base. The docs describe it as permissionless, but the Terms of Use name the United States and several other countries as Prohibited Jurisdictions, so the two pages disagree. docs.overtime.io ↗
Settlement
USDC, USDT and ETH are the core collaterals, on Optimism, Arbitrum or Base. The collateral API also lists THALES and OVER. Liquidity pools hold USDC, ETH, wBTC or cbBTC. docs.overtime.io ↗
Fees
The AMM adds a protocol fee, currently 2%, on top of oracle-fed odds. Users who bet with $OVER get a reduced margin. The docs index has no separate fee schedule page. docs.overtime.io ↗
Account and ID
No registration: log in with a wallet or a social login. Non-custodial. docs.overtime.io ↗
Payout
Most settlement is automatic, with a 15-minute target; newer or specialised markets can take longer. Winnings are not paid automatically: you claim them on your profile's ticket page. Unclaimed winnings are forfeited 90 days after resolution. docs.overtime.io ↗
Operator
No operating company named. The terms say the platform runs on smart contracts, with upgrades managed by OVER governance token holders. docs.overtime.io ↗
Markets
Sports and esports markets, including live markets and parlays, plus digital options trading. The docs also have an Overtime Casino section. docs.overtime.io ↗
