Automated cross-chain solutions
Until now
Users monitor positions manually, set price alerts, and scramble to add collateral when markets move. There is no automated, non-custodial defense layer that works across chains. LiquidShield changes this — embedding liquidation defense directly into a Uniswap v4 hook.
How It Works
Register once.
Protected forever.
Register & Pay Premium
Connect your wallet, scan your Aave or Morpho positions, choose a defense strategy (collateral top-up or gradual unwind), and pay an upfront premium. 60% goes to the defense reserve, 40% to LP rewards.
Cross-Chain Monitoring
Reactive Smart Contracts on Reactive Network subscribe to lending protocol events across Arbitrum and Ethereum. When your health factor drops below threshold, the RSC triggers a callback to the hook on Unichain.
Automated Defense
The hook atomically extracts defense capital (ERC-6909 burn + take), emits an ERC-7683 cross-chain intent, and the filler executes the defense on the source chain — all within ~400ms via Flashblocks.

Strategy A
Collateral Top-Up
Aave V3 on Arbitrum. Hook extracts WETH from defense reserve, filler deposits as additional collateral. Health factor recovers from 1.1x to 1.6x.
Strategy B
Batched Gradual Unwind
Morpho Blue on Ethereum. N sequential ERC-7683 intents, each for a fractional portion. Position gracefully unwound without cascade liquidation.
