Live countdown events · charities, brands, communities
LΛSTR turns fundraising and giveaways into a live game. Players take a seat, use their bids, and every bid in the final seconds resets the clock. When time runs out, the last bidder wins. Every move is recorded on the blockchain, so anyone can check the result.
Any bid with 10 seconds or less on the clock resets it to 10.
You have 3 bids. Use them wisely.
Event ended
Last bid standing when the clock hit zero.
How it works
No auctions to follow and no prices to watch. Players get a fixed number of bids and one goal: be the last to bid.
Each player buys one seat before the event starts. That's the only payment. Nobody pays more later.
Every seat comes with the same number of bids. Bids have no cash value. They're your moves in the game.
When the clock is in its final seconds, a bid sends it back up. Timing matters more than speed.
When the clock reaches zero, the last player to bid wins the prize. The result is final and public.
Who it's for
Galas cost a lot to organise, and donors are tired of being asked. With LΛSTR, supporters take a $5, $10 or $50 seat for a shot at a real prize, and they stay for the show.
A countdown keeps people on the page for minutes instead of seconds. Launch a product, reward customers, or build a list around a live moment.
Run a countdown during a stream or a community night. Everyone plays together, and the final seconds make the moment.
Payments and proof
Players pay the way they prefer. Whatever the payment method, every event writes its full history to a public ledger anchored on Solana. Your supporters don't need a crypto wallet to benefit from blockchain proof.
Fundraising calculator
All the money comes from seats. The winner never pays anything after the game, so the numbers are known before the event starts.
Example only. Before payment processing and platform fees. Rules for prize events differ by country and region.
Provably fair
Each bid is chained to the one before it with a cryptographic hash. Change one line and every hash after it breaks. Snapshots of the chain are written to Solana during and after every event.
The game engine is deterministic. Replay an event's bids and you get the same winner, the same timing and the same payout.
A single process orders every bid, so two people can never "both" be last.
Payouts run once, and only once. Cancelled events refund every seat without anyone pressing a button.

The story
Players bought seats for a chance to win real products for a fraction of their price. The countdown mechanic was born.
The countdown concept ran online as OOBOX from 2016 to 2023.
Rebuilt from scratch with a verifiable engine, blockchain proof, and card or crypto payments.
Questions
Not for card events. A wallet is only needed for events paid in crypto. Either way, the results are recorded on the blockchain.
You choose the starting clock and the reset time. Most events run for a few minutes. The finish is decided by how many bids players have left and when they use them.
A product, like a TV or a trip, or a share of the seat money. For product prizes we can handle delivery to the winner.
Each event has a minimum number of seats. If it isn't reached before the start, the event is cancelled and every seat is refunded automatically.
An embeddable version for partner websites is in early access. Tell us about your organisation below and we'll get in touch.
Every event has a public ledger. Each bid is linked to the previous one by a hash, and the chain is anchored on Solana. Anyone can recompute it.
