What DrawSeal does

A giveaway always unfolds in the same order: you prepare it, you collect entries, you draw, you announce — and, if all went well, nobody disputes it. This page follows that order and says what the platform does at each stage.

One stage appears here that other tools do not have: proving. It is the reason this product exists, and it happens in the middle of the journey, not at the end.

1. Prepare

Two ways to draw

  • A scheduled draw: entries accumulate, the draw happens at the time you set, one or several winners are picked in cascade.
  • Instant win: each entrant knows immediately whether they won. Every entry’s outcome is fixed before opening and recomputable by anyone after closing.

What to remember

An ordinary instant win says “lost” with nobody able to contradict it. This one recomputes — a consequence of how it is built, not a promise.

What you set

  • One or several prizes, with photos, description and delivery countries.
  • The entry window and the draw time, in your time zone.
  • Bonus entries: verified referrals, address confirmation, declared actions.
  • A minimum age, a geographic area, e-mail domains to exclude.
  • A frequency: one entry per person, per day, or per week.
  • The giveaway in French, English and Spanish — entrants get their e-mails in the language they were reading.

The association raffle (add-on)

A DrawSeal giveaway is free: nobody stakes anything, nobody pays to enter. An authorised association may still need the same proof for a raffle, where tickets are sold. This mode exists for them.

The platform takes no money and sells no ticket: the association sells them itself, off the site. What it brings is what every raffle lacks — the proof that the draw was not rigged. Each entrant sees their number of entries published before the draw, and recomputes the winner afterwards.

  • Each entrant’s ticket count comes from a column of the imported file, and enters the sealed fingerprint: it can no longer move.
  • The organiser declares their authorisation order, its town and their association; the town and the association are checked against public registers, the order number is not — and the page says so.
  • The generated rules stop claiming the entry is free: they state the raffle, its authorisation, and that buying a ticket gives no tax receipt.

Restricted, deliberately

This mode is opened only to workspaces that ask for it, and it assumes a municipal authorisation under article L.322-3 of the French Internal Security Code. That is not a commercial restriction: it is the law.

2. Collect

The sign-up page

Hosted, ready to use, in your brand’s colours. You can add up to eight questions — postcode, date of birth, size, whatever you need — and offer separate consent boxes: accepting the rules and subscribing to your newsletter are not the same thing, and merging them into one box would make the collected data unusable.

Beyond your own page

  • A snippet to paste on your site: the giveaway card shows on your page, the button opens the official page.
  • A QR code, in PNG or SVG, for a poster, a shop window, a table mat or a stand.
  • An advent calendar (add-on): one page, one door per day, a giveaway behind each door. A door only opens on its date, and what it hides is stripped server-side — you cannot read the page to find tomorrow’s prize.
  • A list you supply: import a CSV and the draw runs on it.

Against fraud

Disposable addresses excluded, duplicates detected, a cap on entries per IP address, anti-robot checks. The filtering is deterministic and announced in the rules: it applies before the list is sealed, and the count of exclusions is published with its reason. An exclusion that cannot be explained is not a rule, it is a decision.

3. Draw

Before entries open, a secret seed is drawn and its fingerprint published. The source of randomness — drand, a public network whose output nobody controls — is announced in advance, and the value it will produce does not exist yet.

At closing, the entry list is frozen, its fingerprint published, then timestamped with a third party. The draw follows. The seed is revealed. Each of these steps is dated and public, in that order, and the order is what makes the proof: you cannot pick a seed based on randomness that does not exist yet, nor add someone to an already sealed list.

4. Prove

This is the stage other tools do not have, and it is no reproach: a spinning wheel or a filmed generator produces a result, never a trace. Nothing in the video distinguishes a draw run once from a draw re-run fifteen times.

  • A public verification page, where anyone recomputes the winner in their own browser, with no account and without trusting us.
  • The engine’s code is published under an open licence: the same code draws and verifies, not a copy that might drift.
  • A PDF certificate carrying the fingerprints, the timestamp and the replay of the six checks — the document to produce when someone disputes.
  • A shareable video of the draw, rendered from the already sealed result.

The question to ask any tool

If an entrant accuses you of rigging the draw, what do you show them? As long as the answer is “my word”, the tool proves nothing.

5. Put to use

A giveaway is only worth running if what it collects comes back to you. Confirmed entries leave through whichever door you choose:

  • A CSV export, with each address’s status — confirmed or not, unsubscribed or not, excluded and why.
  • A connector to Brevo or Mailchimp: confirmed addresses join your list on their own.
  • Signed webhooks to plug in your CRM, Zapier or Make without writing one connector per tool.
  • A campaign report: entries, confirmation rate, referrals, exclusions by reason — in the same document as the draw’s proofs.

6. What you need not handle

  • The rules document is generated from your settings and published at a stable address. A condition not announced before entry would not be enforceable.
  • Double opt-in is handled, so is unsubscribing, and entrants’ GDPR requests have their own form.
  • Entrant data is anonymised after a retention period you set — without past draws ceasing to be verifiable.
  • Entry is free: this is not gambling, so there is no licence to obtain and no money flow from entrants.

Frequently asked questions

Do you need to code to verify a draw?

No. The public verification page recomputes the winner in the visitor’s browser and shows the verdict of the six checks. The code is published for those who want to go further, but nobody needs to open it.

Is instant win really verifiable?

Yes, and that is what sets it apart. The winning positions follow from a seed committed before opening and from public randomness that did not exist at that moment. At closing, the seed is revealed and anyone recomputes the full set. What it does not guarantee — that an organiser will not play their own game — is a matter for the rules, as everywhere else.

Can the giveaway live on your own site?

Yes, via a snippet to paste. The card shows on your page; the “Enter” button opens the official page, so your visitors see the real address — which is what gives the “Verified by DrawSeal” badge its value.

What happens to the addresses collected?

They are yours: CSV export, e-mail connector or webhook. The file states, for each address, whether it is confirmed and whether it consented to your newsletter — those are the only ones you should market to. On our side, they are anonymised after the retention period you set.
