“Trust us” is not an audit.
Provably
fair.
Every lottery says it is fair. Almost none can prove it to you personally. A provably fair lottery is different by construction: the randomness, the winner selection and the payouts are all public, and anyone — you, tonight, without asking permission — can re-verify any draw ever run. This page explains how that works in plain language, then walks you through verifying a real draw.
The problem with “certified fair”
Traditional lotteries
A state lottery's fairness rests on process you cannot inspect: sealed machines, private audits, regulator oversight. That system mostly works — but your only role in it is faith. You cannot check the machine, replay the draw, or follow the money from pot to winner. When something does go wrong, it is discovered years later, by insiders.
On-chain draws
An on-chain lottery inverts the trust model. The rules are a smart contract anyone can read; the randomness arrives with a cryptographic proof; the payouts are transactions anyone can follow. Fairness stops being a promise and becomes a property you can test — which is exactly what we will do below, on a real Sunday draw.
Where the randomness comes from — Pyth Entropy, in plain language
01 · Two parties commit
When a draw is requested, a random contribution is fixed on-chain in the request transaction itself, while Pyth's provider has already committed to its own sequence of numbers in advance, as a hash chain. Neither side can see or change the other's input — like two sealed bids.
02 · The numbers combine
Both numbers are revealed and cryptographically combined into one final random value. Neither party alone can predict or steer the outcome — biasing it would require both to collude, and the commitments make after-the-fact tampering detectable.
03 · The contract obeys
The final value lands in the prize-pool contract's callback, which picks the 13 winning tickets and pushes the USDC to their wallets in the same flow. No human touches the selection; the sequence number and random value are recorded on-chain, forever.
Verify a real draw yourself — three minutes, no tools
- Step 1 — Open the draw history. Go to ticket4.life/history. Every draw is listed — including the labeled Genesis and Protocol draws from the beta — with its date, pot, payouts, and its Pyth proof: a sequence number and the final random number.
- Step 2 — Open the transaction. Each draw links to its transaction on BaseScan, Base's public explorer. You are now looking at the same data every node in the network validated — not our website's copy of it.
- Step 3 — Follow the money. In the transaction's token transfers you will see the USDC leaving the prize pool in 13 payouts — one per winning ticket, 50% / 25% / 10% to the podium and 15% shared by ten more. A wallet holding several winning tickets appears once per ticket; during the beta the protocol's inventory often does, so expect repeated addresses. Add the payouts up: they equal the pot the draw announced to the cent (sub-cent rounding dust stays in the pool). In draw #3 (19 July 2026), for example, $15.83 left the pool for 13 tickets the moment the random number arrived.
- Step 4 — Check the count is honest. The supply is on-chain too: with the current number of minted tickets public, “13 winners out of N tickets” is not a marketing claim but an arithmetic fact you can check against the Transparency page.
What provable fairness does not prove — the honest part
Provable fairness guarantees the draw is honest — it says nothing about whether the product is good. It does not prove the pot will be large, that the yield engine will perform, or that the contracts are bug-free. It does not make a ticket a safe asset. At Ticket4Life it also coexists with a fact we label rather than hide: during the early beta, the protocol's own tickets play too, so the first winners repeat — each of those draws is still provably fair, and each is labeled on the history page. Verify the fairness; judge the rest with your own eyes.
