A launchpad with its numbers on the table · Uniswap v4 · Robinhood Chain
Demand in. A quarter out.
The meter does the selling.
The creator of a Flowgate coin holds 81% of the supply — and can never touch a coin of it. It sits in a machine that sells only against measured demand, caps the creator's take at 25% of the peak net ETH inflow, and never sells below the opening price. You are reading the whole deal right now; the contract just enforces it.
Every number, before you buy anything
Three rules, all in code
The rate
A shared hook keeps a per-coin ledger: ETH bought in, ETH sold out, and the highest their difference has ever stood. The creator may be paid at most 25% of that peak. No demand, no exit — and sells pull the net down, so the entitlement does not grow again until the old peak is passed.
The floor
19% of the supply is seated as one liquidity position from the opening tick to the bottom of the grid — and the Launchpad that holds its NFT has no function to withdraw, transfer or approve it. The Meter's sells carry a hard price limit at the opening tick: it never pushes the price below the level the coin launched at.
The machine
`crank` is callable by anyone, pays always and only the creator, and is the only thing that ever moves the 81% — into the pool, never to an address. The creator cannot dump what the creator never holds. The Meter's own sells pay no fee and are never counted as demand.
What the creator gets — the whole list
income one
The basin
A flat 1.8% of every swap's ETH side, withdrawable any time. On the creator's own trades too — wash volume pays the fee to itself and loses the rounding, so it earns nothing.
income two — and the last one
The crank
Up to 25% of the peak net ETH that outside buyers ever put in, paid in ETH by the contract, against the pool, like any sell. There is no transfer of stock to any address, no time unlock, no admin path, no second exit.
honesty notes — in code as in copy
- · The peak is a high-water reading, written on every swap. ETH already extracted is not clawed back when buyers later sell.
- · The Meter's sells push the price down like any sell. The cap bounds the drain; it does not remove it.
- · One large buy that spikes the net sets the peak even if it is sold straight back. The spike costs its buyer the fee twice and unlocks at most a quarter of itself — a losing trade — but the reading exists and this site shows it.
- · `bought` is measured net of the fee, so the rate is 25% of 98.2% of what buyers send. The rounding always lands against the creator, never against you.
