THE PROBLEM

!

No Advanced Orders On-Chain

DEX traders lack limit orders, stop-losses, and bracket orders — forced to watch markets 24/7 or use centralized alternatives.

%

LP Losses During Volatility

Liquidity providers suffer impermanent loss with static fee models that don't adapt to market conditions.

~

Fragmented Trading Tools

Quants juggle multiple platforms for DeFi, CEX, lending, and derivatives — no unified strategy execution layer.

ON-CHAIN HOOK FEATURES

MegaQuantHook.sol — Deployed on Unichain Sepolia

EWMA Dynamic Fees

Auto-adjusts swap fees (0.05% – 1.0%) based on exponentially weighted moving average of volatility. Protects LPs during turbulent markets.

On-Chain Limit Orders

Deposit tokens → receive ERC1155 claim tokens → auto-execute when price crosses target tick via afterSwap(). No keepers required.

Stop-Loss Orders

Trigger in the same direction as price movement. Auto-liquidate positions if price falls below threshold — fully atomic on-chain.

Bracket / OCO Orders

Linked take-profit + stop-loss pairs. One-Cancels-Other: when one fills, the partner is automatically cancelled on-chain.
