Open proposals for high-impact hooks waiting to be built.
A Request For Hook (RfH) is a community-submitted idea or ecosystem need for a Uniswap v4 hook — a feature, mechanism, or experiment someone wants to see built. This is a resource created for developers in the Uniswap Hook Incubator. We encourage devs to explore your own ideas including building an integration with your company.
We’ve decided to make this page public to encourage new ideas. This is a non-exhaustive list as there are infinite range of hooks that can be built on v4.
| Hook Name | Description |
|---|---|
| Gas Price Fees | A hook that dynamically modifies Swap Fees (LP Fees) in the related pool in response to movements in average gas price onchain, which can make pools more competitive by decreasing fees during periods of high gas and increasing fees during periods of low gas around a base fee. |
| JiT Rebalancing Hook | A hook that has LPs transfer their tokens to the hook, instead of the Pool Manager directly, and does active management for the tokens. Originally it places all liquidity full-range across the pool. If a “large” swap is detected (large can be defined by % of reserves, or a certain dollar amount, etc) - the hook takes all liquidity it’s managing and concentrates it in a +- 1 tick range around the current tick, allowing the swapper to get access to high liquidity depth without causing much slippage and having these LPs gain most of the fees around that tick. After swap, it rebalances back to full range |
| Nezlobin’s Directional Fee | A hook that dynamically increases/decreases swap fees in one direction to deter large price movements caused by arbitrageurs that can create toxic order flow to mitigate impermanent loss for LPs. |
| CSMM Custom Curves | A simple custom pricing curve (CSMM) implemented as a NoOp hook that follows the invariant $x + y = k$ instead of $x * y = k$ |
| LAMMBert | Another custom pricing curve implemented as a NoOp hook that follows the Lambert W function. Tweet reference |
| Async Swap Fulfillments | For large swaps, accept input tokens from the user and NoOp the actual swap. Later, at a “random” point in time - through VRF Oracles for example - pick an unfulfilled swap and execute it. The idea is to deter sandwich attackers by introducing randomness for swap executions that can cause high slippage. |
| Coincidence of Wants (CoW) | Waits to match limit orders before hitting AMM.A modification of the limit order hook that NoOps the swap functionality and keeps orders unfulfilled for a threshold amount of blocks hoping to fulfill the order through a coincidence of wants. If no CoW is found, then order is executed similar to limit orders. |
| Hook Name | Description |
|---|---|
| Dynamic Fee Hook | Automatically adjusts swap fees based on market conditions to optimize fee generation and liquidity utilization. This hook can be made customizable to specific asset pairs and types as well. Can be based on volatility, reward/loyalty programs, gas price spikes, etc. |
| Rehypothecation Hook | Allows LP positions outside of the active tick to be deposited into lending protocols to earn yield until the liquidity is needed for a swap. |
| Custom Curve Hook | Allows LPs to implement custom price curves to optimize pricing for specific assets. |
| Asynchronous Swap Hook | Ability to enforce temporal and/or other constraints to fill swaps (i.e., application specific sequencing, coincidence of wants, etc.) |
| MEV-Mitigating Hooks | Hooks that tackle MEV (Maximal Extractable Value) with template strategies to prevent different forms including front and backrunning, sandwiches, JIT, and more to improve execution for users. |
| Reward Aggregator | Distributes incentives to liquidity providers based on pool activity, boosting participation in targeted pools. |
| Liquidations Hook | A customizable hook designed to efficiently and safely handle liquidations. |
| Auto-Position Rebalancing | Automates the rebalancing of liquidity positions to optimize capital efficiency for LPs. |
| Oracle Hooks | Enables custom or novel price feeds by recording data (e.g. Time-Weighted Average Price) for integration with other DeFi protocols. |
| Permissioned Pool Hook | Enable compliant-hooks for institutions by allowing for arbitrary rules and logic to affect pool behavior, such as restricting pool access to participants based on KYC or geolocation status. |
| Auto-Hedging Hook | Protects liquidity providers from impermanent loss through automated hedging strategies. |
| **Time-Weighted Average Market Maker (**TWAMM) Hook | Facilitates large trades over time, minimizing price impact and attracting larger retail and institutional liquidity. |
| LRT Liquidity Hook (analogous to Sanctum in Solana) | Special logic for LST/LRT AMMs. See details in blog post by Peteris Erins |
| Internalized MEV | LPs earn MEV profits. E.g. through offchain/onchain ahead of time bidding for top-of-block transaction rights. |
| Oracleless Lending Protocol | Creating a new lending protocol offering features like flexible liquidation thresholds, oracle-free operations, and enhanced earnings for liquidity providers. Link for more details. |
| Tornado Cash on Hooks | A Tornado-like system, utilizing all of Uniswap's liquidity as its pool. Tweet with more detail. |
| Hook Safety as a Service | Insuring safety of a hook up to a certain amount. Tweet with more detail. |
| Gasless Swaps | Incentivizing traders via a non-toxic MEV executer with gasless swaps. Tweet with more detail. |
| Keeper Activity Hook | An intuition on using v4 hooks to facilitate keeper activity. Tweet with more detail. |
| UniBrain Hook | The UniBrain hook is designed to automatically trigger onchain actions using an automated Dutch Auction via a Uniswap V4 Pool. It can turn Uniswap v4 into a hub for triggering onchain function calls. Doc with more detail |
| Value Accrual Designs | A simple hook fee introduces vampire/fork risk. Retaining LPs will be crucial to justifying hook fees. Tweet with more detail. |
| Auction-Managed AMM | An auction-managed AMM that shows the design space of v4. Tweet with more detail. |
