What exists today, and what this does differently

What is new

A tutorial pairs Keyless with randomness, but no live event raffle product was found.

Closest things out there

Aptos randomness tutorials; off chain raffle apps.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

The money path, built in

How it earns for you

Guests never pay to enter and the draw is never gated. Hosts pay a monthly plan for bigger rooms and door tools, and larger organisers pay for multi draw events.

No entry fees: paid entry raffles are regulated in many countries, so the app does not sell tickets. Gas (well under $1 per raffle) can be sponsored by the owner.

The pitch, ready

Event raffles where guests join with Google and the draw uses Aptos onchain randomness that anyone can check.

Problem: Meetups, clubs and fundraisers draw names from a hat or a spreadsheet. When a friend of the host is picked, people assume it was rigged and the host has nothing to show. Guests will not install a wallet just to enter.

Solution: Guests join with Google through Aptos Keyless. Rules are published first, the entry list is frozen and hashed on chain, and a single call to Aptos randomness picks the names. A public proof page lets anyone check every step.

Why now: Aptos ships onchain randomness and Keyless sign in, sponsored gas makes entry free, and small models can flag duplicate accounts for a host to review.

Market: Monthly meetups, campus clubs, church and school fundraisers, conferences and community groups that run draws, and later any fair choice by lot.

The ask: Pilot communities in Nairobi and Lagos, and grant support from ecosystem programs such as Aptos Foundation Grants.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

Home: meet Wanjiru, 31, who runs a Kilimani fintech meetup where last month's hat draw was called rigged.
Setup: pick three names, door code every 90 seconds, draw at 19:30, and publish the rules.
Door: 78 guests join with Google; the helper holds two copies of one guest and Wanjiru removes them with a public reason.
Door: freeze the entry list on chain.
Draw: call the draw once, the drum spins, three names appear; Kevin asks for a redraw and the module refuses.
Proof: Brian, never drawn, checks every line from the bus and shares the card.
Owner Revenue: change the Community price in the paywall editor and preview the user Plans sheet.
Owner Growth and Roadmap: launch campus week, then request the v2 sponsor slots build.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

Meetups, community events and school fundraisers run raffles from a hat or a spreadsheet. When the winner is a friend of the host, people assume the draw was rigged, and there is nothing the host can show to prove otherwise. Guests also do not want to install a wallet just to enter.

What exists and what is new

The pieces exist. Aptos ships onchain randomness through its randomness API, with official tutorials that pair it with Keyless sign in, and many off chain raffle apps and random name pickers are in daily use. Our research did not find a live event raffle product that combines Google sign in, a door check in, an entry list frozen and hashed before the draw, a single allowed draw call and a public proof page for guests. The novelty is in packaging a known primitive for a real room of people, not in the randomness itself.

The data it runs on

Per raffle: the rules (prize count, who can enter, code rotation), each entry as a Keyless account address with a display name of first name and initial, the door check in status, the frozen entry list hash, the draw transaction and its winners, and any removals with a written reason. Emails and Google profile data are never published.

1.The mission

Give every community a draw that the most skeptical person in the room can check from their own phone.

2.Why people can't resist it

Check it yourself The proof page lets any guest confirm their entry was in the list and the draw was called once. Skeptics become the loudest fans.

Ten second join Google sign in through Keyless means no seed phrase and no app install, so almost everyone in the room enters.

The live moment The drum spinning on the projector and the winner appearing on every phone at once is the best five minutes of the night.

3.How it works for real

Join with Google: The projector QR opens a web page. Guests sign in with Google through Aptos Keyless, which derives an Aptos account from the login without a seed phrase. Gas is sponsored by the host through a fee payer account.

Door check in: A rotating code (default every 90 seconds, last two valid) proves the guest is in the room. Optional desk check in by the host for prizes of higher value.

Raffle module in Move: A Move module stores rules and entries, freezes the list with a hash at the set time, and exposes a single draw entry function marked #[randomness] that calls aptos_framework::randomness to pick winners. A second draw call aborts.

Proof page: A public page reads the module's events through the Aptos indexer and shows the list hash, the draw transaction, winners and any removals with reasons, with links to an explorer.

Door helper agent: A small model such as Claude Haiku or GPT-4o mini reads anonymised check in events to flag many accounts on one device or accounts made the same week. It suggests; the host decides in public.

Notifications: Winners get an in page alert and an email from the host's own sender. Prize handover happens in person; the app never holds money or prizes.

4.Cost per use and pricing

Per raffle with about 80 guests: around 80 entry transactions plus one freeze and one draw on Aptos, typically a small fraction of a US cent each at current gas prices, so well under $1 in total sponsored by the host. The door helper uses a few thousand model tokens, under $0.05. Hosting is about $10 to $20 a month. A meetup running one raffle a month spends roughly $12 to $25 a month all in. Gas and model prices change; check current rates.

Meetup Free up to 50 entries

One raffle at a time, Google join, proof page.

Community $15 a month

Up to 500 entries per raffle, door codes, the duplicate flag, draw history page and custom branding.

Events $79 a month

Several raffles per event, sponsor logos, export of the proof for organisers, and team accounts for door staff.

5.Growth loop

Every guest at every draw sees the product working and gets a proof link that they share in group chats. Other organisers in the room ask how to run their own. The share card from a skeptic who checked the draw is the strongest ad it has.

6.Risks and guardrails

Gambling law: Paid entry raffles are regulated in many countries, including Kenya. The default is free entry with donated prizes; owners must check local rules before charging for tickets.

Sybil entries: One person with many Google accounts. Door codes, device flags and optional desk check in reduce it; the host removes entries in public with a reason.

Privacy: Only account addresses and first name plus initial are shown. Emails and profile data stay private and are never written onchain.

Host abuse: A host could freeze the list early or remove rivals. Every freeze and removal is a public event with a timestamp, so guests can see it.

Randomness misuse: Randomness must be used only in a private entry function so it cannot be tested and aborted; the module follows the Aptos guidance for this.

Venue connectivity: Rooftops have weak signal. Join works on slow connections and the list freeze waits for the host's go.

8.Where this is going

Now
One Nairobi meetup draws its raffle on Aptos and the rigged jokes stop.
Next
Other meetups, campus clubs and church fundraisers run free draws with a proof page.
Later
Any fair choice by lot, from school places to housing lotteries to volunteer rotas, can use the same checkable draw.
The big one
Communities expect to verify every draw that affects them, and trust in small public decisions goes up.
