The loss every LP pays, caught and turned into yield.
A normal Uniswap position quietly bleeds about 11% a year to arbitrageurs. Lambda cancels it with a real short on Hyperliquid, opened and resized automatically, across chains, with no off-chain bot, so the loss returns to you as funding income.

The loss has a mirror image, and it pays.
A short position on a perpetual exchange collects a funding fee that, over time, is the same size as the loss a Uniswap pool suffers. Same number, opposite sign. Lambda holds both at once.
Modeled from historical volatility and funding rates, not a guarantee. Full model in the docs.
One automatic loop, across three chains.
A Uniswap v4 hook owns the pool's position, tracks your exact delta, and emits a signal the moment it drifts past the band. It also charges a directional fee that makes informed flow pay the LP.
event HedgeRequested( poolId: 0x92fc…373b, delta: +1.92 ETH, nonce: 17)
A Reactive Smart Contract watches that event from another chain and fires the hedge instruction in response, entirely on-chain, with no centralized bot in the loop.
A hedger calls the live CoreWriter precompile (0x3333…3333) to open or resize a real short on Hyperliquid. The funding it earns routes back to you as claimable income.
coreWriter.sendRawAction( action: OPEN_SHORT, market: ETH-PERP, size: 1.25 ETH)
On testnet, Reactive's Lasna can't route callbacks to HyperEVM, so legs ① and ② run live and the Hyperliquid leg is proven separately against real HyperEVM mainnet state on a fork (the real hedger fires a correct CoreWriter order, asserted byte-for-byte). On mainnet they become one loop, a one-line config change the Reactive Network team confirmed carries over unchanged. See the full mechanism →
A real hedge, opened across chains.
A directional fee in beforeSwap is becoming a standard v4 pattern. Lambda has it, fuzz-tested. The part nobody else ships is the hedge itself: a real short on Hyperliquid, opened automatically across chains through Reactive, with no off-chain bot. That live cross-chain loop is the hard part, and the whole point.
The short is a live position on Hyperliquid via the CoreWriter precompile, not a mock.
A Reactive Smart Contract routes the hedge across chains itself, with no off-chain bot in the loop.
Ships h = 0.65, about 1.4% liquidation risk over 90 days, versus ~19% for a full hedge.
