How Hybirdex works

How it works

1. 01Anyone buys or sells $HYBRID, wherever it trades. The trade pays a 2% creator tax plus the launchpad's 1% fee.
2. 02The launchpad credits the creator tax and 70% of its own fee to the vault, inside its fee escrow. The vault is the coin's fee recipient, written at launch.
3. 03Anyone calls poke() on the vault. 2% of the claim goes to the caller as a tip, 23% to the team wallet, 75% to the vault's buy budget.
4. 04buy() spends the budget in small bounded steps: ETH straight into NVDA or SPY, taking turns.
5. 05The stock tokens stay in the vault. No function sells them or sends them to a person.
6. 06A holder burns $HYBRID through redeem() and receives a pro-rata slice of both stock tokens.

What the vault can do

• Claim its own fees from the launchpad's escrow.
• Pay the tip and the team share, fixed at 2% and 23%.
• Swap ETH into NVDA and SPY inside its limits.
• Hand a pro-rata slice to whoever burns the coin.

What it cannot do

• Sell a stock token.
• Send assets to any address except through redeem().
• Change its split, its two assets or its limits.
• Be upgraded, paused as a whole, or owned.
• Be emptied by the team: there is no such function.

One switch: a guardian address can pause and resume buy(), for the day a pool or a price reference breaks. It cannot touch assets and it cannot stop redeem().

Fee split

Money enters through one door: the trading fee of $HYBRID. A 2% creator tax on every buy and sell, plus 70% of the launchpad's own 1% fee. Together about 2.7% of taxed volume reaches the vault's claim.

• buys NVDA and SPY for the vault75%

• team wallet, in ETH, same transaction23%

• the caller of poke()2%

Nobody can change these three numbers after deploy, including the team.

Arithmetic at three volumes

$50,000 of taxed volume a day

fees $1,350 · vault $1,012 · team $310 · tip $27

$250,000 a day

fees $6,750 · vault $5,062 · team $1,552 · tip $135

$1,000,000 a day

fees $27,000 · vault $20,250 · team $6,210 · tip $540

This is arithmetic at a chosen volume, not a forecast. At $225 per NVDA and $780 per SPY (2026-10-13), the middle row is about 11 NVDA and 3.2 SPY a day.

No second door

• No subscription and no credit pack.
• No fee on the Trade page from us. Each trade goes straight to its own venue.
• No fee to redeem beyond the 3% that stays in the vault for the other holders.

Buy engine

The vault buys in small, spaced, price-guarded steps. Anyone may call buy().

Size of one buy

at most 0.25 ETH, at least 0.005 ETH

Size of one claim

at least 0.0005 ETH; fees under that wait at the launchpad for more

Gap between buys

at least 10 minutes

Price guard

result within 1% of the pool's own 30-minute mean and within 2% of what the price feeds imply, or the buy reverts

References

the stock token's price feed, the chain's ETH / USD feed, and the pool's own time-weighted price

Freshness

no buy while a feed it needs is over 26 hours old; when the US market is closed the budget simply waits

Asset order

NVDA, SPY, NVDA, SPY, so equal value goes to each (assumption A1). An asset is stepped over, keeping its turn, only while its own price feed cannot be used

Route

ETH → stock token, in one swap, in the chain's main DEX pool for that token

Who may call

anyone

Depth on 2026-10-13: NVDA pools $1.46M ($3.32M traded in 24 hours), SPY pools $4.0M ($0.9M in 24 hours). One buy of 0.25 ETH is about 0.08% of NVDA's largest pool.

Taking stock out

redeem() burns `amount` of the caller's $HYBRID and sends, for each of the two stock tokens: amount / total supply × the vault's balance × 97%.

• The other 3% is the exit fee. It stays in the vault, so every exit leaves a little more per coin for the rest.
• Example, numbers invented for the arithmetic: the vault holds 100 NVDA and 60 SPY, supply is 1,000,000,000. Burning 10,000,000 coins (1%) returns 0.97 NVDA and 0.582 SPY. 0.03 NVDA and 0.018 SPY stay behind.
• A slice that rounds to nothing is refused. There is no other minimum.
• The caller names the least it accepts of each part, and the call reverts rather than send less.
• Fees not yet claimed are not part of a redemption, and neither is ETH that has just arrived in the buy budget. Whoever leaves gets a little less, never more.
• ETH that has sat in the budget unspent through one whole 15-day window is part of a redemption, pro rata like the stock. In normal running there is none, because each buy spends what is there; it exists so that a pause or a broken pool can strand nothing.
• The windows are fixed and counted from the launch, so nobody has to call anything for the clock to run: a fee the vault claimed and never spent is redeemable no sooner than 15 days and no later than 30 days after its claim.
• A holder who cannot receive one part (its issuer has paused a stock token, or the wallet is a contract that takes no ETH) can leave that part behind. It stays in the vault for the holders who remain.
• The issuer of the stock tokens restricts them in some countries. The app asks for a declaration before a redemption and before a purchase of a stock token. The contract cannot check where a person lives.

Why the slice is measured against total supply

• The slice is amount / total supply, including coins that sit in the liquidity pool and can never redeem by themselves.
• Counting only coins in circulation would be a door: park coins in a pool, the circulating figure drops, every remaining coin claims more, redeem the rest, pull the parked coins back out.
• Total supply only ever goes down, and only by burning. Nobody can move it in their favour.
• The share that belongs to pool-held coins is not lost. It is claimed by whoever buys those coins and burns them.

Open season

Book per coin is what one coin would receive from redeem(). The page watches one number: price / book.

Above 1.00

the normal state. Holders sell on the market or keep holding.

At 1.03

a banner: close to book.

Below 1.00

open season. Buying on the market and burning returns more stock than the coins cost. Anyone can do it.

Each such burn removes supply and leaves the 3% behind, so the gap closes from both sides. No reward is added by us: the gap is the stock itself.

Said plainly: this is a backstop under the price, not a floor close to it. On the reference's own fee history the vault would have been about a third of market value on the coin's worst day. A buy on the market also pays the coin's 3% trading fee.

Ledger and meter

• Every purchase is one line, written by the vault itself in the transaction that made it: time, block, ETH paid, tokens received.
• One note a day sums the lines of that day, in the style of a treasury notice. A day with no purchase is noted too: "No fees, no purchase."
• The meter is one figure on the front page: the share of $HYBRID volume that came from our own wallets, over the last 7 days and since launch.
• Our wallets are listed by address: team, caller script, dev lock. The figure is computed from the chain.
• If the meter is ever high, it says so in the same type size.

Before launch the ledger is empty and the meter reads 0.0%. Both start with the first trade. That first trade is our own: the dev buy inside the launch transaction is counted as ours, so the meter starts at 100% and falls as others trade.

none; a slice that rounds to nothing is refused

Dev bag

• 30,000,000 $HYBRID (3% of supply), bought inside the launch transaction at the curve's opening price: about 0.05 ETH before fees.
• Sent straight into a time lock for 90 days.
• After 90 days it is an ordinary balance. Any move from it shows in the ledger like every other event.
• It has the same claim per coin as any other holder: the lock can redeem only after it opens.

No tiers, on purpose

• There is no staking, no lock, no holder level and no payout on a schedule.
• The coin buys a claim, never an edge: the claim is the same per coin for a wallet with 1,000 coins and one with 10,000,000.
• The one thing a holder can do that a non-holder cannot: burn the coin and take stock tokens out.

Launchpad settings (curve size, graduation point, launch fee) belong to the launchpad and can change. They are read again on launch day, never copied from this page.

Contracts

HybirdexVault

holds the stock tokens; launch, poke, buy, redeem. No owner, no proxy, every parameter fixed in the constructor. It launches the coin itself, as its deployer and fee recipient, and makes the 3% dev buy in that same transaction.

DevLock

created by the vault at launch. Holds the dev bag until day 90, then releases exactly 30,000,000 coins and burns anything else that was sent to it.

HybirdexLens

read-only. Gives a page one snapshot of the vault and the exact result of a trade before it is sent. Holds nothing.

Vault interface

poke()

claim fees, pay tip and team

Nine things the review had to prove

1. 01No call path moves a stock token out except redeem().
2. 02redeem() never pays more than amount / supply × balance.
3. 03The split is 75 / 23 / 2 for every claim of any size.
4. 04buy() cannot spend more than 0.25 ETH or run twice inside 10 minutes, whoever calls it.
5. 05buy() reverts when the result is more than 1% from the pool's 30-minute mean or more than 2% from what the price feeds imply, or when a feed it needs cannot be used.
6. 06The guardian cannot move value, cannot block redeem(), and cannot keep ETH out of redemptions: a fee the vault claimed and never spent is redeemable within 30 days.
7. 07Dust: a 1-wei redeem, a dust claim and a donation of stock tokens, ETH or WETH cannot be turned into a gain and cannot stop the vault.
8. 08Reentrancy through the coin, the stock tokens or the swap route changes nothing, and no caller can choose which asset a buy goes to.
9. 09The team's bag is 30,000,000 coins and never more, whatever is sent to the lock.

All nine have passing proofs on a fork of the live chain. Three rounds of adversarial review found 21 things (1 high, 3 medium, 8 low, 9 for information), none of which let anyone take stock or ETH out beyond the rules. 19 are closed in code and were attacked again by the reviewer, who found nothing further; 2 are powers of the launchpad and are listed under Risks. The findings, what closed each one and every proof (180 tests, 106 of them the reviewer's) are in the contracts folder of the project's repository, which is not public yet. Nothing is on mainnet, and no outside firm has audited the contracts.

Risks and outside powers

These were read from verified contracts on 2026-10-13. They are real, and no wording of ours removes them.

Stock tokens, through their issuer

• Upgradeable through a beacon.
• Roles in the verified contract can pause the token, block an account, burn a balance and update the multiplier that carries corporate actions.
• If the vault's address were blocked or the token paused, that token's part of a redemption stops until the issuer lifts it. A holder can still leave with the other parts; nobody on our side could move the assets either.

Launchpad

• Its owner can redirect any coin's fee recipient after a 3-day timelock. Stock already in the vault is out of reach; future fees are not.
• Its owner can also pay a curve's waiting fees straight to the fee recipient, past the escrow. For this coin they would land in the vault whole, as buy budget, with no tip and no team share taken.
• After graduation, the fee on a buy is taken in coins, and converting those to ETH needs the launchpad's operator.
• Graduation takes two calls that anyone may make. Between them the coin cannot be traded anywhere; the caller script and the app make whichever is due. If the pool stayed unopened for 7 days, the launchpad's owner could take the curve's reserves back.

Price references and pools

• Feeds go stale outside US market hours: buys wait.
• Liquidity can leave a pool: the 1% guard stops the buy.
• A pool's own price history is a ring of fixed length. Somebody swapping in a pool in every block could outrun it and make the vault's buys wait for as long as they kept paying. Anyone can lengthen the ring for good; the launch plan does it before the coin exists.

Vault contract

• The vault is new code. A review can miss an error, and an ownerless vault cannot be repaired after the fact.
• No outside firm has audited the contracts. The review was done in-house: a second reviewer, working against the first with its own tests, on a fork of the live chain.
• The price feeds the vault reads (NVDA, SPY and ETH against the dollar) are run by a third party. If one stops printing, or answers with something that cannot be a price, the vault stops buying against it; ETH left unspent for a whole 15-day window becomes part of every redemption.
• About 8% of the coin's supply ends up in the launchpad's own locker when the coin graduates and can never redeem. Its share of the vault stays in the vault.

Questions

Is $HYBRID a stock?

No. It is a memecoin. The vault behind it holds stock tokens issued by a third party. Those tokens follow the price of a share; they are not the share, and they carry no ownership or vote today.

Can the team take the stock out of the vault?

No. The vault has no owner, no withdraw function and no proxy. The only way a stock token leaves it is redeem(), called by someone burning their own coins. A guardian can pause buys and nothing else.

What do I receive when I burn?

For each of NVDA and SPY: your amount divided by total supply, times the vault's balance, times 97%. The other 3% stays in the vault for the holders who remain.

What happens if nobody trades?

No fee, no purchase. The vault stops growing and team income stops the same hour. The stock already in the vault and the right to redeem stay exactly as they are.

Is the vault a floor under the price?

It is a backstop, not a floor close to the price. The book can be far below the market price. It matters most when a coin is dying, which is when other coins have nothing.

Who calls poke() and buy()?

Anyone. The caller of poke() receives 2% of the claim as a tip. The team runs one caller so the vault never stalls; it has no special rights, and a stranger's call does the same thing.

Can I redeem from any country?

The issuer of the stock tokens restricts them in some countries, including the United States. The app asks for a declaration before a redemption and before a purchase of a stock token. You are responsible for knowing whether you may hold them.

Where is the contract address?

On the landing page and in the Addresses section of this page, and it is the same in both. Until the coin is launched there is none, and any address shown to you before then is fake.
