How it works
Protection at settlement.
Sigmoid is powered by FairOpenHook, a Uniswap V4 hook that targets the launch transaction patterns extracting value before a community has a fair chance to participate.
The problem
Supply extracted in the replayed SWARMLER #1212 attack.
Price swing observed in the replayed attack.
Value captured for the community from that attack path.
Launch value leaks to bots while the flywheel remains underfed. The FairOpenHook counters both problems at the pool layer.
Three mechanisms
Dynamic fee
0.30% base, rising to 37.8% at 25% impact, feeK 150, capped at 90%.
Circuit breaker
Reverts swaps moving price over 25% in the 100-block opening window.
Wallet caps
Caps opening buys at 0.5% of supply and one swap per 3 blocks.
Attack replay
Do not trust. Replay.
The replay reproduces the SWARMLER #1212 path and compares settlement with and without the FairOpenHook.
