What is Stackers
Stackers is a 3,000-piece voxel NFT collection on Robinhood Chain (chain id 4663), tied to the $STACK token launched on Pons. An activated Stacker automatically collects the assets you choose every hour, paid for by $STACK trading fees. Those assets build up inside the NFT itself, and travel with it if you sell. There are twelve options: eleven tokenized stocks (AAPLx, MSFTx, NVDAx, AMZNx, GOOGLx, METAx, TSLAx, PLTRx, AMDx, GMEx, SPCXx) and USDG for a stable payout. $STACK itself is never paid out: it is a burn token, spent to activate, upgrade and fuse. Ten hand made one of a kind pieces exist inside the 3,000.
The site is also a trading desk: the Leverage page lets you long or short those same stocks with leverage, powered by Lighter, with zero fees from Stackers. And My Stack shows everything in one place: your Stackers, what they are holding, your earnings and your positions.
Buying & activate
Minting is finished. All 3,000 were minted at 0.0025 ETH and the mint is closed for good. The only way in now is the secondary market, on OpenSea. Supply only falls from here, because fusing destroys the Stackers it absorbs.
- Buy: pick one up on the secondary market. It is yours but asleep, and earns nothing yet.
- Activate: burn 25,000 $STACK. It now earns at tier 1×.
- Choose your stocks: pick up to three. Until you do, a Stacker is paid in USDG by default.
Activation is personal. When a Stacker is sold or transferred it goes back to sleep, and the new owner burns 25,000 $STACK to wake it. The tier and fuse bonus never reset. The only tokens that ever leave your wallet are the ones you burn in a transaction you sign yourself.
Earning: rounds, tables and tiers
Rounds are hourly. Each round, the fee pot is divided across all listed assets based on every Stacker's split and tier. Crediting happens every hour and you never claim it. Buying is separate: once an asset's pot reaches the minimum trade size, a bot buys it and puts it in your Stacker's vault, or straight in your wallet if you have chosen that instead. That minimum is 0.01 ETH at launch and can be set between 0.001 and 1 ETH, never in a way that can take your credit. Anything under it rolls into the next round, so small balances build up rather than being lost.
Your split decides what you collect, not how much. Pick up to three assets and give each a share of your hourly earnings. Choosing USDG means a stable dollar payout. Until you pick, a fresh activation defaults to USDG. Two Stackers at the same tier are credited the same value whatever they picked; what it is worth afterwards depends on the assets you chose and the price they filled at. You can change your split once per day.
Your Stacker must be active before a round starts to earn it. No payout sniping, no collect-and-run.
| Tier | Total $STACK burned |
|---|---|
| 1× (active) | 25,000 |
| 1.4× | 75,000 |
| 1.9× | 150,000 |
| 2.5× | 300,000 |
| 3.5× | 850,000 |
Burns are cumulative and permanent. The tier stays with the NFT forever, including when it is sold.
The bot cannot touch prices. The contract works out the minimum acceptable output itself from the pool's own 30 minute average and allows at most 3% below it. Anything worse reverts and the money rolls forward to the next round. A broken bot can only delay a round. It can never take from one.
How your piece is chosen, and the reveal
Your piece is drawn inside your own mint transaction and shows the moment it confirms. No waiting, no second step. The draw takes one piece out of the pieces nobody has claimed yet, so all 3,000 are handed out exactly once and none twice. We do not pick, hold back, or reserve anything: the one token minted before launch was for setting up the marketplace page, and it drew like any other.
There is no waiting and no reveal day. Your Stacker shows its real artwork and its real traits from the moment the mint confirms, on this site and on OpenSea.
Minting was open to wallets only. A contract could otherwise have minted and cancelled itself unless it drew a grail, which would have let a bot fish for the rare pieces. That path was closed throughout.
Fusing
Merge two or three of your Stackers into one. Their tier weights add together, with a 20% bonus for two and a 30% bonus for three. Fusing burns 50,000 $STACK, then 100,000 more for a third. Absorbed Stackers are destroyed permanently, so the supply only falls.
Being straight about the trade: because the bonus adds weight, the fused Stacker earns more than its parents did combined, and every other Stacker's share of each round goes down very slightly. You gain, everyone else pays a little for it. What fusing does for the collection is shrink it.
The survivor is stitched from its parents. Half the body comes from each, joined down the middle by gold stitching, with one eye from each parent and a gold mark on the chest carrying a gem in each parent's colour. A third parent gilds it: the seam goes solid gold and a third gem is set. The Stacker you picked first keeps its side, its background and its number. The art updates here straight away; OpenSea refreshes on its own schedule, so it can take a little longer to show there.
Because the picture is stitched from the exact pair that fused, no two fused Stackers look alike, and no minted one can ever look like any of them.
The vault comes with it. Everything the absorbed Stackers had banked moves into the survivor in the same transaction, and nothing is left behind on a burned token.
The vault
Your stocks build up inside the NFT. Every hour, what your Stacker earns goes into that Stacker rather than your wallet. It stays there until you take it out, and there is no deadline.
It belongs to the token, not to you. The balance is held against the token number, so if you sell the Stacker the stocks inside go with it. That is the point: a Stacker holding $340 of stock is worth at least $340 to whoever buys it next, and you can see exactly what any Stacker is holding on the explorer before you buy.
Taking it out is free. There is no fee, and there is no setting anywhere in the contract that could add one later. You sign a message, which is free and is not a transaction, and we pay the gas to submit it. If our relay is ever down you can claim it yourself for about a cent instead. Your money never depends on our server being up.
You can turn it off. Switch any Stacker to pay straight to your wallet every hour instead, and switch it back whenever. Vaulting is simply the default.
Nobody can touch what is in there but you. Only the wallet holding a token can move what that token holds, and it can only ever move to that same wallet. Not us, not the keeper, not the deployer. The contract has no owner, no pause, no upgrade and no recovery hatch, which also means anything sent to it by mistake is stuck for good.
Leverage: the trading desk
The Leverage page lets you long or short the same stocks your Stacker earns, with leverage, straight from this site. The markets are perp contracts that track each stock's price, plus crypto. Prices on the page are live.
Powered by Lighter. Trades execute on Lighter, the perps exchange, not on Stackers contracts. Stackers adds no fee to any trade. Lighter currently charges no trading fee on these markets; perp positions still pay or receive funding, and Lighter sets its own terms.
Nothing custodial. Your margin sits in your own Lighter trading account, created automatically by your first deposit. Stackers never holds your funds, your keys, or your positions. Every order is signed by you, and you can use Lighter directly without our site at any time.
The earnings bridge. Point your split at USDG and your Stacker earns trading margin every hour. One tap moves your earnings into your trading account. An automatic version is planned after launch.
The honest part. Leverage can lose you everything you put in, fast. A liquidation closes your position and your margin is gone. This is a separate protocol we do not control, and nothing about it is guaranteed. Trade only what you can afford to lose.
Fees & where the money goes
| Flow | Split |
|---|---|
| Trading fees (WETH side) | 80% buys tokenized stock for holders, automatically |
| Mint (closed) | 0.0025 ETH → treasury, while it was open |
| Resale royalty | 5%, declared on chain through ERC-2981. Marketplaces that honour the standard pay it; the contract cannot force one that does not |
Trading generates the fees that pay you. 80% of everything that arrives is forwarded into the earning engine every 15 minutes, which buys the assets you picked and puts them inside your Stacker. The remaining 20% is kept as a reserve that funds keeper gas, the site, and development; it is taken from newly arrived fees only, never from what has already been set aside. $STACK is never handed out: the only way it moves is when a holder burns it to activate, upgrade or fuse, so the supply only falls.

The first engine was retired on launch night: a mismatch between the code and the router meant every purchase reverted, and its funds cannot be recovered. It is listed here because it exists and holders can see it, not because it is in use. Everything now runs through the engine above.
The vault is the one that holds your assets, so it is the one worth checking. It has no owner, no pause, no upgrade and no way for anybody but the holder of a token to move what that token holds.
Addresses are published here and nowhere else. The $STACK token is added to this table the moment it launches.
Security: we will never message you first. We will never ask you to sign anything on another site. If an address is not on this page, it is not ours. Bookmark this page.
FAQ
Can the team touch my tokens?
No. The contract can only burn tokens you send in a transaction you sign yourself. There is no staking and no custody. You can verify this in the source code when the addresses are published.
What do I actually earn?
Tokenized stock from the table you chose. By default it builds up inside your Stacker and stays there until you take it out, which is free. You can switch any Stacker to pay straight to your wallet every hour instead.
Can I lose money?
Yes. Stock can go down, $STACK can go down, and earnings depend entirely on trading volume. Nothing is guaranteed.
What happens when I sell my Stacker?
Whatever is in its vault goes with it. That is the point: the buyer is buying the NFT and the stock inside it, and they can see exactly how much that is before they buy. If you want to keep it, claim it first, which is free. Anything you already claimed is in your wallet and stays yours. The buyer gets the tier and the fuse bonus too, but it arrives asleep: they burn 25,000 $STACK to wake it.
Do I need to claim my earnings?
Only when you want them out. Crediting and buying happen automatically every hour with nothing to sign, and the stock lands in your Stacker's vault. Taking it out is one press and costs you nothing: there is no fee, and we pay the gas. If you would rather skip that step, switch the Stacker to pay straight to your wallet. If a transfer ever fails, it is held against your Stacker and can be pushed through later. It is never destroyed.
What if the keeper goes down?
Fees keep building up and the next successful run catches up. The bot can delay rounds but it can never take funds or worsen a price, because the contract enforces the minimum price itself.
Who runs the leverage trading?
Lighter, a separate perps exchange. Our site is a window into it. Lighter charges zero trading fees and Stackers adds nothing on top. Your margin and positions live in your own Lighter account, never with us.
Can I lose money trading with leverage?
Yes, easily, and fast. A liquidation wipes the margin you put into that position. Leverage is optional and completely separate from your hourly earnings, which keep flowing either way.
Where do I see everything I own?
The My Stack page. Your Stackers with their tiers and splits, what each one is holding, your earnings and your open positions, all on one page.
Can you take what is in the vault?
No, and not by choice: there is no function that would let us. Only the wallet holding a token can move what that token holds, and it can only ever move to that same wallet. There is no owner, no pause, no upgrade and no recovery hatch in the vault contract. The same fact has a sharp edge worth knowing: anything sent to it by mistake is stuck for good.
Why would I fuse?
A bigger tier weight and a permanent bonus, held in one NFT instead of several, and a permanently smaller collection. It does not raise what other holders earn; because the bonus adds weight, their share of each round dips slightly.
Can anyone snipe the grails?
We will not pretend this is impossible. Because your piece is drawn as you mint, so that you see it right away, a determined bot can work out what a mint would give it and only send the ones it likes. Contracts cannot mint here, which rules out the cheap version of that trick, but it does not rule out all of it. The honest position: minting early is not an edge, timing is not an edge, but a well built bot could take more than its share of the ten grails. We chose showing you your piece instantly over locking that door. If you want the grails, mint more.
