One stroke. One price. Ink does not lie.
Every swap should land where you signed.
Between signing and settlement, value bleeds. Not because the market moved. Because someone else took a cut for sitting in between.
- 壹Sandwich
A bot buys in front, sells behind, keeps the spread. The tax is silent.
- 貳Front-run
Searchers reorder the block around your intent to extract the difference.
- 參Toxic slippage
Because the trade is visible, its impact is worse than it needs to be.
Protection is computed on-chain, before the swap settles.
A Uniswap v4 hook uniquely enables SUMI: it runs inside the swap, in the same transaction. No trusted relay. No off-chain sequencer. One motion.
Value stays in the pool.
Never emitted. Real assets.
Traders keep the fills that used to be skimmed. LPs keep the fees that used to leak. Stakers share what the hook actually recaptured — paid in real assets, not $SUMI.
Twelve pools. Every stroke accounted for.

The cut is clean.
The shown price is the defended price. There is no hidden second version of the trade.
