One token.
One thousand donkeys.

Buy STONKEY on a bonding curve. Mint a Stonky. Burn 200 STONKEY to activate it. Claim its tokens over time. The activated NFT keeps earning a share of funded stock allocations after its token bundle finishes unlocking.

This is a local design preview. No contracts, token, NFT, stock purchase or real transaction is live. All displayed wallet actions use demo funds.

Two token allocations

Where	Tokens	Share
Bonding curve	500,000	50%
Inside the NFTs	500,000	50%
Total	1,000,000	100%

The previous matching-token allocation has been removed. The token launches first with no founder ETH. Buyers supply the real ETH backing as they buy tokens.

A gentle opening curve

The curve uses virtual constant-product pricing, the same broad approach described in Pump’s official program documentation. This is a custom Robinhood Chain design, not a Pump.fun deployment or an exact copy of its parameters.

The opening is relatively flat, then the slope gradually increases. Sales move back down the same curve. These numbers describe quotes at specific net sales, not a prediction of market demand.

Curve allocation sold, net	Tokens	Quoted price / opening	Real ETH backing
0%	0	1.000×	0.0000
10%	50,000	1.108×	1.0526
20%	100,000	1.235×	2.2222
50%	250,000	1.778×	6.6667
100%	500,000	4.000×	20.0000

The illustrative opening quote is 0.00002 ETH per token. Buying 200 activation tokens at the start costs about 0.004041 ETH including a 1% fee, before gas. NFT mint price is an additional cost.

Curve formula and limits

With q equal to net tokens sold by the curve:

price(q) = 0.00002 / (1 − q / 1,000,000)²

The formula uses virtual pricing parameters of 1,000,000 tokens and 20 ETH. Those are mathematical offsets; they do not add real tokens or spendable ETH. Real ETH starts at zero. At 500,000 net tokens sold, buyers have contributed 20 ETH of backing and approximately 0.202020 ETH of fees.

A sell can receive only real available ETH. Excess tokens remain unsold; the opening quote is not a funded price floor. Fees are recorded separately in the asset paid. Activation burns remove wallet tokens, not curve inventory, and do not themselves change the quoted price.

This calculator lets all 500,000 curve tokens sell, then pauses buying until tokens return. It does not implement automatic DEX graduation. A Pump-style migration must retain part of the existing curve allocation to pair with actual ETH; selling every token leaves no tokens to migrate. The threshold, migration budget and uninterrupted sell path remain launch decisions.

Three mint prices

Stage	NFTs	Mint	Tokens inside	Activate
1	333	0.01 ETH	350	Burn 200
2	334	0.02 ETH	500	Burn 200
3	333	0.03 ETH	650	Burn 200

Total: 1,000 NFTs, 500,000 tokens inside and 20 ETH of mint proceeds if every NFT sells. The average NFT contains 500 tokens. Net issuance after activation is 150 / 300 / 450 tokens per NFT. This is proportional to the mint price; earlier NFTs buy the same ongoing allocation weight for less ETH.

Activation starts a seven-day wait, followed by 180 days of linear token release. It also starts stock-allocation eligibility. Transfers must preserve activation and already claimed amounts; moving an NFT cannot restart its bundle. Actual transfer settlement is not implemented in this preview.

Where the ETH goes

Source	Creator	Future DEX liquidity	Stock purchases	STONKEY buy-and-burn
NFT mint	20%	40%	40%	—
Collected trading fees	20%	—	60%	20%

The mint allocation funds 4 ETH creator proceeds, 8 ETH future liquidity and 8 ETH stock purchases at sellout. Future-liquidity ETH is held pending an explicit migration/deployment rule. No extra token stash is created. Adding this ETH to backing or migrating it changes the economics and is not simulated in the curve calculator.

The ongoing split applies only to fees actually collected. During the curve phase these would be contract trading fees; after a DEX migration they would be the project’s collected LP fees, after exchange deductions and its actual share of active liquidity. Routes elsewhere need not pay Stonkey. Token fees are not realized ETH until actually converted.

COIN is the proposed stock token: exposure to a real crypto exchange business. Robinhood’s asset registry lists it, but executable quotes, treasury access and custody are unverified. Robinhood Stock Tokens provide economic exposure through debt securities; they are not direct corporate shares or a promised ETH dividend.

Why keep the NFT?

Its token bundle is finite. Its stock-allocation rights continue while the system earns fees and funds purchases. Proposed weekly distributions use eligible NFT holding time; every activated NFT has equal weight. No trading fees means no new fee-funded stock purchases or burns. Claims carry no extra protocol charge; network gas still applies.

The site shows zero claimable stock in the preview because none has been purchased. The proposed accounting credits earned allocations to their owner and future eligibility to the next owner on transfer. This requires implementation, custody and reconciliation tests.

All NFT releases total 500,000 tokens against 200,000 activation burns, or 300,000 net issuance before later buybacks. Burning tokens and recycling fees cannot guarantee a rising price or manufacture outside demand.

Build status

The website keeps buying, selling, minting, activating and token claiming in one native interface using a demo wallet. The new curve tests verify conservation, input-asset fees, no fictitious ETH backing, partial fills, burn accounting and inventory boundaries. No wallet transaction is sent.

Before a live launch: implement and audit integer contract settlement; specify curve graduation and the mint-funded liquidity policy; connect actual Robinhood wallet/RPC/stock routes; simulate the combined mint, vesting and fee cycle; verify failure, retry and transfer accounting. Hosting and actual desktop/mobile browser acceptance are not verified in the restricted environment.
