[ANN] Last Pixel — On-Chain Survival Game With Smart-Contract Prize Pool

[lastpixellive]

Hi everyone,

Last Pixel is a social experiment about the value of persistence. In online games, usually luck, hype or the algorithm wins. Here it's the opposite: the winner isn't the one who guessed right, but the one who doesn't give up. 1,000,000 people press a pixel on a shared canvas again and again, confirming: "I'm still here." Window after window the field empties out, and the canvas becomes a living map of human attention — you watch how, out of a million, only one remains. This is neither a lottery nor a bet, but a collective story about patience, where every pixel is someone's decision not to give up for one more window. The last survivor takes the entire prize pool — because persistence beats luck.

Launching Last Pixel — a live on-chain survival game on Base where one final active participant wins the entire locked prize pool.

This is not a token sale, ICO, or investment product.

It's a long-form elimination game based on timing, consistency, and survival.

How it works

• There are 1,000,000 total pixels
• Anyone can claim one for $3 (crypto)
• Each pixel is assigned randomly and permanently
• Every active window, participants confirm they are still active with one click
• Missing a window means permanent elimination

The first window lasts 24 hours. Each following window becomes 10 minutes shorter. This continues until only one active participant remains. That final survivor wins the entire live prize pool.

Referral rewards

• Earn $0.30 USDC for every direct paid invite — paid instantly in stablecoin
• No cap on invites: your earnings scale with your network
• Rewards are tracked transparently and verifiable on-chain
• Separate on-chain leaderboard reward pool for top referrers — extra on top of the base commission
• Best part: you keep earning from your referrals even after you're eliminated from the game

Early entry advantage

• Window 0 starts at 24 hours
• Every next round becomes shorter
• Earlier players begin under easier survival conditions
• Later rounds become increasingly more demanding

Trust-minimized design

• Prize pool is locked inside a Base smart contract
• Team cannot withdraw participant funds
• Team wallets are excluded from winning
• Participant snapshots are committed on-chain via Merkle roots
• Public verification data is published for every round
• If snapshots stop for more than 5 days, participants can trigger refunds

FAQ: https://lastpixel.live/faq.html

I quickly went over your FAQ page and the part that mentions "how the money will be returned if your project stops" caught my attention... From what I understand, funds will be returned to the wallets on our dashboards, but doesn't that mean they're still under your control? Am I missing something?

I quickly went over your FAQ page and the part that mentions "how the money will be returned if your project stops" caught my attention... From what I understand, funds will be returned to the wallets on our dashboards, but doesn't that mean they're still under your control? Am I missing something?

Thanks for the question — it's about the most important part, trust. Let me answer from the actual code.

The funds are not held in any team wallet, and we don't "send refunds" manually. The entire prize pool sits inside the smart contract on Base, and the team has no withdraw function — the pool can only go to the winner, or back to participants in refund mode.

Emergency path (dead-man switch):
– If the activity snapshots aren't updated for more than 5 days, anyone can call triggerDissolution() — not just the team.
– Refund mode turns on. The contract uses a "lag-frozen" Merkle root from two commits earlier — so a malicious root published right before vanishing can't be used.
– A 48-hour window applies so everyone can verify the refund data against the public snapshot (also published to an open GitHub repo with an immutable history).
– Then claimRefund sends funds strictly to your own dashboard address — even if someone else submits the transaction, the money can only go to the owner. Nobody, including the team, can redirect it.
– The undistributed referral pool in this scenario doesn't go to "top referrers" — it's returned to participants together with the prize pool.

The team receives nothing and doesn't control the distribution — it's all hardcoded. Verify it yourself in the contract: 0x1D03EE835CB592A72e4127BA05cCAa0437FDfe72 (triggerDissolution, claimRefund).

On referrals, since it came up: referral rewards are not locked until the game ends. Each payment is split at the moment it's made, and the referral share lands in your wallet right after your invitee's paid signup — no need to wait for the marathon to finish.

For full transparency: what's locked and verifiable on-chain is the prize pool (and the emergency refund). Referral accounting is handled by the payment system at the time of payment — that's why it's fast, but it's part of the backend, not the contract's on-chain logic.

First of all, respect for making the contract immutable. That is quite rare these days, even though immutability was originally one of the main features of smart contracts.

Second, I have a question. I see that the contract has an administrator, or owner, and also a committer. Usually, administrators or privileged roles have special rights that regular users do not have - that is the whole point of defining such roles in a smart contract.

Could you please clarify what rights the owner and the committer have in your contract?

You wrote:

So they cannot influence the following functions: proposeWinner, proposeLeaderboard, cancelWinner, cancelLeaderboard, setExcludedWinner, freezeExcluded, finalizeWinner, and finalizeLeaderboard. Is this correct?

And if they cannot influence the distribution of tokens in any way, then what is the practical purpose of having the owner and committer roles in this contract?

Good question — and a fair correction to make first: the team is not "unable to influence" those functions. There is influence, but it's bounded — the roles can only propose, cancel, or block; never redirect funds.

committer (hot gas key): publishes the snapshot root (commitDailyRoot), and can proposeWinner / proposeLeaderboard. But a proposed winner must be provably in the latest published snapshot as active (Merkle proof, lastActiveCount == 1, not excluded), and leader payouts are capped to ≤3 addresses and ≤ the accrued pool. It cannot name an outsider or exceed the pool, and it cannot finalize or withdraw anything.

owner (2-of-3 multisig): an emergency brake, not a hand on the wallet. It can cancelWinner / cancelLeaderboard (only cancel a pending proposal in the challenge window), setExcludedWinner (only bar addresses from winning — that's where team addresses go), freezeExcluded, rotate the committer via timelock, and set the audit URL. It cannot name a winner, withdraw the pool, or speed up a payout.

Who actually pays out? finalizeWinner, finalizeLeaderboard, claimRefund, triggerDissolution are permissionless — anyone calls them after the window. The payout needs neither role.

Why the roles exist: all heavy logic (pixel accounting, referrals) is off-chain, so committer must push the root and propose — strictly inside published data. owner is the kill switch to cancel a wrong/challenged proposal.

Worst case — full collusion of both. They still can't take the pool. The most they can do is stop publishing snapshots; after 5 idle days the dead-man switch lets anyone call triggerDissolution, returning the pool (plus leaderboard escrow) to participants via claimRefund. So there are exactly two outcomes: (a) the legitimate winner from the public snapshot, or (b) a refund to everyone. "Funds to the team" is simply not a function that exists in the contract.

It seemed like an interesting challenge.

Can any ETH address be used to receive the reward/recommendations?

I have a question: does no percentage of the prize money or registration fees go to the administrators?

Thanks for checking it out! 🙏

1) Address: Yes — any standard ETH/Base address works for both the prize and referral payouts (everything settles on Base). Just make sure it's an address you control, not an exchange deposit address.

2) Prize money: No — the prize pool is locked in the smart contract and the team has no withdraw function over it, so admins can't touch the winner's prize, the referral payouts, or the leaderboard escrow. Those are guaranteed on-chain.

To be fully transparent: of the $3 entry, $1.00 goes to the prize pool, $0.30 to referrals, $0.06 to the leaderboard escrow, and the remaining $1.64 covers operating costs (infra, gas, dev). So the split is public and only the ops portion funds the project — not the prize.

Contract is verified on Base if you want to check the logic yourself: 0x1D03EE835CB592A72e4127BA05cCAa0437FDfe72

Thank you for your reply.

Now a question about the game: whenever a window passes by, is a pixel deleted, even if it's not occupied, or only one that is already occupied?

If a user doesn't enter a window, their pixel is automatically deleted, right?

Thank you for your reply.

Good question! Windows only apply to occupied pixels. Free (unbought) pixels are never deleted — they simply stay available to buy.

Each participant's window is personal: if you don't confirm before your window ends, only your pixel is eliminated — it doesn't affect anyone else. So yes — miss your window → your pixel is automatically eliminated.

💳 Payments couldn't be easier!

Our payment gateway accepts any popular cryptocurrency (BTC, ETH, USDT, USDC, BNB and more) and converts it automatically. You can pay from any blockchain network — no manual swaps, no hunting for a specific token.

Just pick the coin and network you like → pay → you're in. The gateway handles the rest. ✅

Each participant's window is personal: if you don't confirm before your window ends, only your pixel is eliminated — it doesn't affect anyone else. So yes — miss your window → your pixel is automatically eliminated.

Couldn't that lead to an unbalanced game if you start early?

Anyone who signs up today will have to wait several months until the window is less than 10 minutes. This can discourage early bookings, leaving everyone waiting until the last minute.

How are you planning to motivate users who buy pixels early?
Because there's not much advantage in buying today or only buying an hour before the end.
Of course, if you're busy you won't be able to buy, but it may take a while to get much uptake at this stage.


In turn, will the lost pixels become available for purchase again?

Great questions! 🙌

Motivating early participants:

Windows shrink gradually, so those who join early build the confirmation habit while windows are still long and easy. Latecomers will have it much harder.
The real early-bird advantage is the referral program: $0.30 per invitee + top-3 leaderboard prizes $30k / $20k / $10k. Start early and you gather referrals while the field is still filling up.
And most importantly — pixels are limited (1,000,000). Early entry = more of the free field to choose from and a guaranteed spot.
On eliminated pixels: no, they do not go back on sale — an eliminated pixel stays permanently marked as eliminated. You can only buy pixels that no one has ever claimed. So the earlier you join, the more of the free field is still available.

⚡ Heads up: in the coming days we're launching viral videos across all platforms at once — mass pixel-buying will kick off across dozens of countries. The pixels could well run out within a few days. A $1,000,000 prize is very attractive, especially since the payout is guaranteed by the smart contract — no cheating is possible.

Not everyone is connected to social media to make recommendations. But I understand the advantage.

From what I understand, the last window is for 1 minute, repeating until only one pixel remains.

How does it work specifically? Does the user simply refresh (F5) the page to validate a new time window, or do they have to close and reopen it?

Does the Telegram bot automatically send a notification whenever you open a new time window?

If the same user has more than one pixel, does the system classify it as "if it were only one"?

Great questions 🙌

How to confirm: you just press the "Confirm" button on the page — one tap. No F5, no closing/reopening. Your next window opens right after you tap.

Bot protection: you can't confirm with a script or bot — the button is guarded by an anti-bot check (Cloudflare Turnstile). Only a real human can confirm, so there's no way to automate your way to the win. That's the whole point of the experiment — personal responsibility and patience.

Notifications: every time you confirm, you get a message in the Telegram bot — confirming your participation in the current window and how much time is left until the window closes. Makes it easy to keep track of your timer.

Multiple pixels, one player: the system counts by participant, not by pixels. One window and one confirmation cover all your pixels at once, and in the finale you count as a single player.

OK, thank you for your answers.
We may be facing a game that could take a long time.

Now, a suggestion: the personal area should also display the number of active and eliminated players, similar to what appears on the homepage.

Thank you for your questions — the battle will be exciting, and the prize is worth it! 🏆 We estimate the game will last no more than 70–80 days. Every participant is interested in attracting as many players as possible, so the prize grows to its maximum.

Great suggestion — by your request, we'll add the active/eliminated counters to the personal dashboard in the coming days. 🙌

📢 Rule update — early players now get a real advantage

You gave us honest feedback: entering early gave no real edge over entering late. You were right. So we changed two rules (already live on the site):

1) Dynamic price. A pixel starts at $3 and rises +$0.10 with every new window. 100% of the increase goes into the prize pool. So the earlier you join, the cheaper you pay — and latecomers grow the pot for everyone.

2) Registration closes at the 1-hour window. Once the shared window shrinks to 1 hour, no new players and no re-entries. You can't just wait for the end to jump in.

Together: early players pay the least and enjoy the calm, long windows; latecomers pay more — and past the 1-hour mark, can't join at all.

Everything else is unchanged: the prize stays locked in a smart contract the team can't withdraw from. Full rules: https://lastpixel.live/faq.html
