Proof — verify every claim yourself

Custody you can walk away with

The load-bearing guarantee is custody. A sportsbook can freeze your balance or slow-walk a withdrawal and you have no recourse. On OVERDOG, withdrawal is always open — there is no hold, no cooling-off period and no approval step — and your account key is exportable. "We can't freeze you" is therefore a structural fact, not a slogan, and the clearest test of any custodian is whether you can get your money back.

Settlement is on-chain

Markets resolve through Polymarket's on-chain oracle, not an OVERDOG trading desk. When an event ends, winning shares redeem for one dollar each and the settlement transaction is public on Polygon. Anyone can audit that a market paid out correctly — there is no opaque grading department that can void a winning bet after the fact.

This is the difference between trusting a brand and trusting a mechanism. A sportsbook asks you to believe its house will grade fairly and pay promptly; an exchange settles through code and a public oracle whose decisions are recorded for anyone to inspect. You don't have to like us, or trust us, for the math to be checkable.

A verified builder, on the record

OVERDOG routes through Polymarket as a verified builder, and Polymarket publishes the register: builders.polymarket.com lists every builder, its verified status and the volume routed through it. OVERDOG is on that list. You are not being asked to believe a badge we drew ourselves — you can open their site and find us on it. An audited, on-chain track record beats any license seal a marketing team can print.

Fees in the slip, no vig in the price

Each trade carries a fee in two parts, one kept by OVERDOG and one collected by Polymarket, and both are included in the odds and payout your bet slip shows before you confirm. There is no vig baked into the market price and no rollover-locked bonus. The exchange sets the price; our part of the fee pays for the interface and tooling, and the rates are set out in our Terms of Service.

What we can't do

Being honest about the limits is part of the proof. OVERDOG cannot move a line, void a winning bet, or change a result after the fact — outcomes are decided by the protocol's oracle. We also can't make betting safe: you can lose what you stake, prices move fast, and availability depends on your jurisdiction. Stake only what you can afford to lose.

And we won't pretend otherwise. The honest version of a betting product names its risks plainly instead of burying them under a welcome bonus. Everything above is checkable; this paragraph is the part you simply have to weigh for yourself before you deposit.
