Borrow ETH
without selling.

A Uniswap V4 hook lending AMM. Lock LOOP, draw ETH from a band below spot — the market price never moves, and every liquidation leaves the pool deeper than before.

how it works

Three moves. One position.

01

Buy LOOP

Trade ETH for LOOP on the V4 curve. A custom LDF concentrates liquidity across 100 bands of 30 ETH each.

02

Lock collateral

Deposit LOOP as collateral at 40% LTV. The position opens at a bound band and is held in the hook, apart from the AMM reserves.

03

Borrow ETH

The hook draws ETH from a band below spot — the one your loan would liquidate in. Spot sits in another band, so it never moves.

lock + borrow = one transaction

the mechanism

Borrowing that
doesn't move the market.

A borrow doesn't swap. The hook removes ETH-side liquidity from a single band that sits below the current price — the band your loan would liquidate in. Spot lives in a different band, so it never moves.

1

Spot preserved. ETH is drawn from a crossed band below spot, never from the active band — so borrows don't touch the market price.

2

No cascade. Because borrows don't move spot, no one else's collateral gets revalued. Liquidation cascades are closed by design.

3

Self-healing. On liquidation the collateral is sold and the ETH proceeds refill the same band — the pool ends up deeper than before, no LOOP burn.
