For competition organisers
Your competition. Your rules. A draw the whole room can check.
You bring the prize, the audience, and the licence. The contract brings the rest — escrowed funds, a sealed list, an on-chain draw, and a receipt every entrant can re-derive. You stay the promoter; the machinery makes meeting your rules easy to show.
The rule your draw is measured against
Evidence, not screenshots.
Rule 8.24 of the UK’s CAP Code — the advertising rules for prize promotions — asks that winners be chosen by a computer process producing verifiably random results — or by an independent person. Most organisers reach for screenshots. You’ll hand your entrants a public blockchain record, re-derivable by anyone, indefinitely.
This page describes a mechanism, not legal advice — rule 8.24 applies to your competition, and your counsel applies it. The Organiser Terms set out what you warrant as promoter.
Two the contract enforces against you
The system works even when you do nothing.
Both are written into the same contract as the guarantees your entrants get. If either is a problem for how you run competitions, this is the wrong service — better to learn that from a page than from a draw.
What your entrants need
Entries are paid in SUI, the coin of the chain the draw runs on, from a Sui wallet — so a first-time entrant needs three things: a wallet app, a little SUI from an exchange, and the answer to your competition’s question. Wallets are free and take minutes; your competition page walks entrants through it. Every paid competition also carries the free entry route its rules describe, at equal weight.
If your audience is not crypto-native, plan for this in your promotion — the proof your entrants get is what they are learning the wallet for.
Admission
Every organiser here is a named, registered entity.
Your registered entity, the register you’re listed in, and the wallet you’ll create competitions from.
Your entity against the register you named, and the licence position for your jurisdiction. Reviewed by hand.
Approval writes your address to the platform’s allowlist — public and permanent. Until then, the contract refuses to create a competition.
What it costs you — all of it
