The mark
only goes up.
Two percent of every trade is placed under the price and cannot be withdrawn. There is no function to call. Dips are absorbed and burned, so the water beneath each token rises and never falls back.
deployment
Four moves. No admin key.
No owner, no pause, no fee setter, no rescue. raise() and sweep() are open to anyone, so the machine runs without us and cannot be pointed anywhere else.
Taken in ETH
Two percent of each swap, collected by the hook. Not a transfer tax. The token itself is a plain ERC20 with no owner and no mint function.
Placed under the price
That ETH is minted into the pool as liquidity sitting just below spot. A standing bid, on chain, that anyone is free to sell into.
The bid does the buying
When price falls into the band it buys, automatically, because that is what an AMM does. Nobody has to press anything.
What it catches, it destroys
Every token the mark absorbs is burned. Supply drops, the same ETH backs fewer tokens, and the water rises again.
It is arithmetic.
Not a lock with an expiry. Not a line in a description. There is simply no code path that moves ETH back out.
mark = floorEth ÷ supply floorEth only rises fees in, no exit exists supply only falls absorbed tokens are burned
Downside you can query.
A bot does not read a website, it reads state. Three calls return a hard lower bound before it ever buys. Nothing else on this chain publishes that number.
