Hook
Sets the fee on every trade, taxes sandwich bots and keeps a price record no single block can move.
5 of 14 V4 hook permissionsHow it works
Liquidity that follows rules.
Liquidity OS runs an ETH/LIQUIDITY pool on Uniswap V4. Its liquidity reacts to the market, carries out rules and protects the people who provide it.
Vault
Deposit once. The vault keeps your liquidity around the price, widens it when markets swing and collects the fees.
Withdraw at any timeEngine
Attach rules to your own position, like "exit if the price falls 6%". Keepers run them for a small tip.
Up to 8 rules per positionLIQUIDITY
A fixed supply of 1 billion. Part of every trade buys LIQUIDITY back and burns it.
Supply only goes downThe hook
A fee that follows the market.
Calm markets trade cheaply. When prices swing, the fee rises so liquidity providers are paid for the risk, and the autopilot range widens to keep earning.

Dynamic fee
Paid for the risk you take
The fee is set on every trade from recent volatility, between 0.30% and 5%.
Sandwich tax
The back leg pays
A trade that reverses a price push made earlier in the same block pays extra, up to the 5% cap, and the extra goes to liquidity providers. That is the closing leg of every sandwich. Any other trade against a same-block move pays it too.
Price record
One block can't move it
The hook records the price before any trade in a block moves it, so a push inside one block never reaches its average. Shifting the average means holding a false price for many blocks, against everyone who trades it back.
The engine
Rules for your liquidity.
Each rule is one sentence: when this happens, do that. Choose a rule and move the level to see how it plays out.
When
- Price above
- Price below
- Out of range
- Date reached
- Every N hours
- Volatility high
- Volatility low
Then
- Close position
- Re-center range
- Limit order
- Reinvest fees
Anyone can run a keeper. Whoever executes a ready rule first earns the tip you set; if no keeper is running, the rule waits until one does.
The token
Trading fees burn LIQUIDITY.
The pool keeps 0.05% of every trade. It builds up until someone triggers the buyback, which spends it on LIQUIDITY and burns it. Anyone can, and the caller keeps 1% as a reward.

Safety
Guarantees written in code.
These rules live in the contracts. Where an owner can still tune something, the limits are fixed in code too.
Exits
Always open
Withdraw at any time, whatever the price is doing.
Triggers
Read the average
Rules and safety checks use the 30-minute average price, never a single moment.
Liquidity
No hit and run
Only the Vault and the Engine can add liquidity. Liquidity that arrives in a block leaves that block's fees to everyone else, so jumping in and out around a trade earns nothing.
Positions
No admin
The Engine has no owner. Nobody can change your rules or touch your position.
Owner limits
Capped in code
The hook owner can retune fees, but never past 5% a trade, 0.2% to the buyback, or a circuit breaker tighter than 10% a block. Nobody can move a deposit.
Using it
Straight from the contracts
Until the app ships, deposits and rules run from Etherscan: deposit on the Vault, open on the Engine. Swaps need a router that supports V4 pools with hooks.
