Frequently asked questions

Yes. PrizeProof is 18+ only. You'll be asked for your date of birth when you register, and entries are blocked until it's on file and confirms you're old enough.

Yes. Your account lets you set weekly and monthly spend caps and a per-competition entry cap. Lowering a cap is immediate; raising or removing one only applies after a 24-hour cooling-off period. You can also self-exclude for a fixed period or indefinitely, which blocks new entries for that time.

By a public commit–reveal draw. Before a competition opens, we generate a secret and publish a cryptographic commitment to it. After close, we publish the frozen list of every ticket, then combine our secret with public randomness from the drand beacon — which doesn't exist until after the pool is frozen — to compute the winning ticket. Nobody, including PrizeProof staff, can steer the result once the commitment is published.

Yes. Every drawn competition has a public verification page publishing the commitment, the full entry snapshot, the beacon round used, and the calculation that produced the winner. Anyone can recompute it independently — see docs/draw-protocol.md, or run scripts/verify-draw.mjs against the published result.

Your own tickets and results always appear on your account's entries page as soon as a draw runs, regardless of anything else. If you win, we also contact you directly using the details on your account. Winners who consent to publicity also appear on our public winners page.

Open a live competition, choose how many entries you'd like, and complete checkout. Each entry becomes a numbered ticket in that competition's single draw pool. You can also enter for free by post — see our Free Entry FAQs below.

Yes. Every competition shows a per-person entry cap on its page, and you can set your own, lower personal limit in your account. Lowering a limit takes effect immediately; raising one only takes effect 24 hours after you request it, as a responsible-participation safeguard.

Not yet. PrizeProof is currently running with a simulated test payment provider while we complete the legal, financial and regulatory steps needed before real money changes hands. No card is ever charged for real. This page will be updated the moment that changes.

Yes. Every paid competition has a free postal entry route into exactly the same draw pool, on equal terms, as paid entries. There is no separate "free draw" — free and paid tickets are numbered from the same sequence and drawn together.

On a plain postcard, write your full name, home address, date of birth, the email address of your registered PrizeProof account, and the exact name of the competition you're entering. Send one entry per card — postal entries are matched and de-duplicated per person per competition. Your card must be postmarked before the competition closes. Full details are in our Free Entry Route document.

Yes — apply through the seller area. After identity verification and an asset review covering ownership, condition, valuation and any encumbrances, our team decides whether and how it's listed. Sellers never control draws, pricing, ticket inventory or winner selection.

Every seller completes identity verification before any asset of theirs can be reviewed, and every asset goes through an evidence review by PrizeProof staff — ownership, condition, valuation and any outstanding finance — before a competition built on it can be approved.

It means PrizeProof staff have recorded a specific, evidenced claim about that prize — for example that ownership was checked, the asset was inspected, or funds to secure it are held — after reviewing supporting evidence. Badges are generated only from these recorded claims, never from marketing copy.

Every live competition has been through PrizeProof's asset review before publication. What has specifically been verified — and when — is listed on the competition page as individual claims, so you can see exactly what has (and hasn't) been checked, rather than taking our word for it.
