Fixed-price listings · permanent floor

Every listing opens at one price. When it closes, that price becomes a floor.

Choose a token, a stock to price it in, and how long the window stays open. Buying and selling run the whole time. At the close the unsold supply burns and everything raised is locked underneath as a bid you can always sell back into.

No bonding curve during the sale. No allocation, no vesting, no claim step. The first buyer and the last buyer pay exactly the same number.

The shape of every listing. Nothing about the floor is discretionary — it is the raise itself, held by the contract, with no owner key and no withdrawal.

Open a listing

Eight fields, then it is immutable forever.

Token name

Ticker

Total supply

A third of this is the most that can sell. The rest burns at the close.

Priced in

The floor is denominated in this asset, so it moves with it.

Tokens per unit

The same price for the first buyer and the last.

Window stays open

Fifteen minutes at the shortest, thirty days at the longest.

Buy fee (%)

On buys only, 1% to 5%. IPOPAD keeps 0.25 while the window is open; after launch you keep all of it.

What this produces

Once deployed nothing here can be changed. You keep the fee and nothing else — the raise belongs to the floor.

How a listing runs

Four states, one of which anyone can trigger. None of them has a privileged caller.

bidReserve ≥ circulating ÷ price

True at every block. The quote the contract holds is always enough to buy back every token in circulation at the floor.

Why it can't drain

Every exit burns

Selling into the floor removes the tokens and exactly their floor value. The ratio it owes can only improve.

Where fees go

Buys only, never sells

The creator's fee sits on entry. Exiting at the floor costs nothing, so a round trip can never be arbitraged.

Questions

The mechanism is trustless. The person who chose the parameters is not — read every listing before you enter it.

One price, then a floor

A raise that cannot be withdrawn is the only price support worth the name.

How the mechanism works, what it guarantees, and what it does not.

What IPOPAD is

IPOPAD deploys a token that sells at one fixed price for a window the creator chooses, then converts itself into a market with a permanent floor. The price is denominated in a stock token rather than a stablecoin, so a listing is priced against an equity rather than a dollar.

There is no bonding curve during the sale, no allocation, no vesting and no claim step. The first buyer and the last buyer pay exactly the same price, and either can leave at any point.

The two phases

Sale

Every token is in the contract from the first block. Buying and selling are both open for the whole window. A fee in basis points is charged on buys only and goes to the creator; selling costs nothing. The most that can ever sell is one third of total supply.

Launch

Once the window closes — or the cap fills — anyone can call launch(). There is no privileged caller and no deadline. It burns the unsold remainder so the supply settles at three times what sold, then seats two sides: the floor, every unit raised less the fee, as a flat bid at the sale price; and the ask, twice what sold, on a constant-product curve whose marginal price starts exactly at the sale price and only rises. Everything the ask takes in is added to the floor.

If nobody bought before the window closed, the whole supply burns and the listing ends dead. Nothing is recoverable and nothing was ever at risk.

Why the floor holds

bidReserve ≥ circulating ÷ price

The quote held by the contract is always at least enough to buy back every token in circulation at the floor price.

→At launch it holds with equality, because the raise is exactly what buyers paid for the tokens they hold.

→Every ask fill adds tokens to circulation and adds at least their floor value to the reserve, because the curve never prices below the floor.

→Every floor fill removes tokens from circulation, burns them, and removes exactly their floor value.

So the reserve can never be drained below what it owes. The floor is not a promise or a treasury policy — it is an accounting identity enforced by a contract with no owner, no upgrade path and no withdrawal function.

Parameters

Field

What it does

name / ticker

Token metadata. Fixed at deploy.

total supply

Minted once, entirely to the sale contract. No mint function exists afterward.

priced in

The stock token the sale and the floor are denominated in.

tokens per unit

The fixed price. One number for the whole window.

window

How long the sale stays open. Minimum 15 minutes, maximum 30 days.

buy fee

Basis points on buys, paid to the creator. Capped at 5%. Sells are never charged.

Buying and selling

During the window a buy fills at the fixed price and a sell returns exactly what you paid, less the buy fee you already paid to enter. Your total cost of a full round trip is the fee and nothing else.

After launch a buy fills from the ask, which starts at the sale price and rises as it fills, and a sell always fills at the floor. Because the ask is never below the floor and the fee sits on top, buying the ask and dumping the floor always loses money — there is no round-trip arbitrage to extract.

Wallet safety

Connecting a wallet to any site is a real risk. Here is exactly what this one does and does not do, so you can verify it rather than trust it.

What this site does

What it never does

Before you connect anything: confirm the domain in your address bar, confirm the factory address in the footer matches the one published by the project, and use a wallet holding only what you are willing to trade with. Every listing is deployed by a stranger — the mechanism is trustless, but the person who chose the parameters is not.
