Your souvenir rarity is determined by how long you held β but four things can push it higher. Overpaying above the minimum when you buy stores a boost that applies to your souvenir when you eventually sell. Promo codes (from Discord, X, or community events) stack on top. Trade in a souvenir you already own to convert it into a single-use boost code. And loyal holders β wallets that have held the potato before β automatically get a bonus when they get bought out again. All boosts stack, capped at Legendary.
| Overpay above minimum bid | Boost | Effect on souvenir |
|---|---|---|
| 0 β 9% | None | Standard rarity based on hold time |
| 10 β 24% | +1 tier | e.g. Common β Rare odds |
| 25 β 49% | +2 tiers | e.g. Common β Epic odds |
| 50 β 99% | +3 tiers | e.g. Common β Legendary odds |
| 100%+ | +4 tiers (max) | Maximum Legendary odds regardless of hold time |
Note: The minimum price increase scales with the potato's value β lower % at high prices so the game stays accessible. At current prices the minimum is shown next to the buy button.
All boosts apply to your souvenir's rarity image and metadata when you get bought out. They stack β but are capped at Legendary.
Hot Potato is built on the Base blockchain. Core game rules β purchases, price enforcement, ETH payouts, and souvenir minting β are governed by the smart contract and cannot be altered once deployed. Additional mechanics such as rarity boosts from promo codes, referrals, and loyalty tracking are applied by the game server at the time of purchase. No individual, company, or entity can alter on-chain outcomes once a transaction is submitted.
All purchases are final. Blockchain transactions cannot be reversed, cancelled, or refunded. Once you send a transaction and it is confirmed on-chain, your ETH is transferred and the contract executes automatically. There are no exceptions.
Participation in Hot Potato involves real financial risk. The price of ETH fluctuates. You may hold the potato for an extended period before being bought out. You may lose money. Souvenir NFTs have no guaranteed monetary value. Only participate with funds you can afford to lose.
The creators of Hot Potato provide this interface as-is, with no warranties. We are not responsible for losses arising from smart contract interactions, network conditions, wallet errors, or market movements. Use at your own risk.
Submitting a buy transaction constitutes your acceptance of these terms. You confirm you are legally permitted to interact with blockchain-based applications in your jurisdiction and that you understand the mechanics of the game.

Not because I wanted another NFT game.
Because I wanted to ask a genuinely interesting question: what happens when you engineer an up-only instrument from first principles β rules transparent, enforcement algorithmic, outcomes inevitable β and invite people to participate anyway?
The Hot Potato is a single NFT. Always for sale. Price only goes up. When someone takes it from you, the contract pays you out and mints your souvenir. The longer you held, or the more you overpaid on entry, the greater the status that souvenir carries.
No hidden mechanics. No discretionary decisions. No promises. The contract does exactly what it says β every time, without exception.
But the game was never really the point.
Beneath it is something I find genuinely fascinating β an exploration of what "up only" means when it isn't a marketing slogan but a cryptographic guarantee. A study in the tension between profit and status.
Between the patience of waiting for your return β and the creeping anxiety of knowing someone, somewhere, could take it from you at any moment.
How will it feel?
Why do humans hold things they know they'll eventually lose? What does ownership mean when it's always provisional?
We also reference the Tulip Factory deliberately. Part irony, part homage β to the enduring strangeness of human speculation, to the way collective belief manufactures value, and yes, to the comedy embedded in all of it.
But ultimately tulips are beautiful. They're deeply social. They bloom, circulate, and pass on. And they come in seasons.
That isn't a cautionary note. It's the philosophy.
Strong hands only. π₯
