Uniswap v4 Hook Ecosystem Heats Up: 8 Early Projects Race Ahead — Who Can Build a Real Business?
- Core Viewpoint: Uniswap v4's Hook technology is spawning a wave of new projects that explore innovations such as dynamic fee adjustment and arbitrage profit redistribution through customizable liquidity pool rules. However, early projects face triple risks — technical uncertainty, liquidity constraints, and disconnect between product functionality and token value — and their true business value has yet to be validated over time.
- Key Elements:
- Hooks are the core innovation of Uniswap v4, allowing developers to write custom operating rules for liquidity pools and execute additional logic at various stages of a transaction.
- Currently popular Hook projects include 8 in total: Hookr, StonkBrokers, What The Hook, Programmable, Claus, Fables, The Standard Reserve, and Bordrless.
- What The Hook attempts to redistribute arbitrage profits: traders in its own pool receive 10%, while the treasury receives 90%; for third-party pools, the split is 5%/45%/40%/10%.
- The Standard Reserve uses Hooks for an on-chain monetary policy experiment, dynamically adjusting token issuance and buyback-and-burn based on net ETH inflows/outflows.
- Key risks include: smart contract security, sharp price volatility due to insufficient liquidity of early-stage tokens, and the disconnect between product features and token value capture.
- Deploying on Uniswap v4 does not equate to an official Uniswap endorsement, and using Hook technology does not mean a project has established a sustainable business model.

In the DeFi world, Uniswap has never lacked imitators, but recently, a batch of new projects has begun trying to build something different on top of Uniswap.
Some of them focus on trading fees, some attempt to redistribute arbitrage profits, some explore new liquidity management methods, and others hope to give token trading more complex execution rules.
Behind these projects is a common technical keyword: Hook.
Hook is not a new feature that Uniswap recently launched. As early as January 2025, when Uniswap v4 officially went live, it was already one of the core innovations of this version. Today, projects built around Hook continue to emerge, bringing this originally developer-oriented technical concept into the view of more crypto investors.
This article reviews 8 relatively popular Hook-related projects recently (not investment recommendations)—Hookr, StonkBrokers, What The Hook, Bordrless, The Standard Reserve, Programmable, Claus, and Fables Finance—to see how developers are using Hook to expand the possibilities of onchain trading.
What Is Hook? Installing "Custom Rules" on Uniswap Trading Pools
Simply put, Uniswap provides basic trading infrastructure, while Hook allows developers to write additional operating rules for specific trading pools.
In Uniswap v4, Hook is an external smart contract attached to a liquidity pool. It can execute custom logic before and after operations such as pool creation, adding or removing liquidity, and trading, allowing developers to design different rules for different markets.
For example, fees can adjust with market changes, trades can trigger rewards, and liquidity pools can also connect to specialized pricing or order mechanisms.
Behind the Hype: Threefold Risks of Early-Stage Projects
Of course, compared with mature DeFi protocols, some Hook ecosystem projects currently attracting attention are still in the product and market validation stage.
The first is technical and smart contract risk. Hook can execute custom logic within the trading process, but this also expands the scope of code that needs review. The fact that Uniswap v4's infrastructure has undergone development and testing does not mean that any third-party Hook automatically inherits the same level of security. Complex trading logic may also lead to unexpected execution outcomes. Custom accounting, external oracles, dynamic fees, and upgradeable permissions can all affect trading and liquidity security.
The second is market liquidity and price volatility risk. Early-stage tokens may see sharp price swings from relatively small amounts of buying and selling due to the small size of their trading pools. Investors should not only pay attention to token price and market cap, but also examine actual tradable liquidity, token holder concentration, bundling levels, token minting permissions, and the trading behavior of large holders.
The third is the risk of a disconnect between product value and token value. Even if a Hook can implement useful functionality, that does not mean the token it issues will necessarily capture protocol revenue. The trading volume, fees, buyback mechanisms, or revenue distribution promoted by a project all need to be carefully considered.
It is especially important to note that being deployed on Uniswap v4 does not equal obtaining Uniswap's official endorsement; using Hook technology does not mean a project has already established a sustainable business model.
Therefore, the following projects are more suitable as an early ecosystem watchlist rather than investment recommendations.
Several Hook-Related Projects Worth Watching
Hookr
Hookr's focus is making it easier for developers and project teams to combine, deploy, and use Hooks. The platform runs on Robinhood Chain and supports both new token issuance and the creation of new Uniswap v4 pools for existing assets. Creators can choose Hook Blocks such as dynamic fees, anti-sniping, automatic burning, and LP rewards to configure different rules for different pools.
Its product scope has already expanded to Builder (creating pools or deploying Hooks with Hook), a Hook directory, an SDK, and HookrScan (for ratings). From this perspective, Hookr's appeal lies not only in issuing tokens, but also in whether it can lower the barrier to using Hooks: helping traders understand the rules, helping developers reuse modules, and helping other products integrate these markets.
However, the more composable the features, the more necessary it is to verify the configuration of specific pools. The official website also clearly states that the contracts have undergone adversarial review but have not yet received an external audit.
According to GMGN data, the Hookr token HOOKR currently has a market cap of $26.5 million, with a peak market cap of $31.43 million.
StonkBrokers
StonkBrokers is a DeFi infrastructure and experimental suite running on Robinhood Chain, focused on stock tokens, Uniswap v4 Hooks, and liquidity pools.
It combines DeFi tools with tokenized U.S. stocks on Robinhood Chain, while also offering an NFT community, Launchpad, and incubation functions. The team describes itself as playing the role of an "onchain Y Combinator" through Special Projects, providing early-stage projects with rails, liquidity, and community distribution.
On October 14 at Beijing time, StonkBrokers used Uniswap v4 Hook functionality and collaborated with Hookr to create a new type of token called "Pair Token," namely a hybrid, auto-compounding ERC-20.
The principle is to merge two tokens into a new token (for example, ETH + NVDA = ETHNVDA, or NVDA + TSLA = NVDATSLA). Each Pair Token represents a proportional share of the corresponding full-range Uniswap v4 liquidity pool. In terms of fees, minting and redemption are free. During compounding, a 10% fee is charged on LP fees, used for STONKBROKER buybacks.

According to GMGN data, STONKBROKER currently has a market cap of $15 million, with a peak market cap of $95.75 million on August 12.
What The Hook
What The Hook (WTH) has a relatively clear product entry point: redistributing arbitrage profits between trading pools.
In AMM trading, different liquidity pools may experience brief price discrepancies due to trading activity. After arbitrage traders discover these discrepancies, they can profit through buying and selling, and push prices across different markets back toward consistency.
What What The Hook hopes to change is not the arbitrage behavior itself, but who ultimately receives the arbitrage profits.
According to its official documentation, What The Hook uses Uniswap v4 Hook on Robinhood Chain to check price discrepancies between associated trading pools, and when execution conditions are met and there is still profit after deducting related costs, it executes arbitrage and distributes the actual gains obtained.
Its documentation lists two revenue distribution methods:
- WTH's own trading pools: traders receive 10% of captured arbitrage profits, and the WTH treasury receives 90%.
- Third-party integrated trading pools: by default, 5% of profits go to traders, 45% to the liquidity pool, 40% to the WTH treasury, and 10% to referral partners.
It should be emphasized that these ratios apply to successfully captured arbitrage profits, and the distribution ratios for specific cooperative deployments can be adjusted.
WTH's business logic lies in the fact that if more third-party trading pools integrate its Hook, the protocol may be able to earn revenue from more arbitrage activity. But it also faces practical limitations: arbitrage opportunities do not appear in every trade, and competitive arbitrage mechanisms, trading costs, market depth, and the number of integrated pools will all affect final returns.
More importantly, revenue received by the WTH treasury does not mean that WTH token holders directly receive corresponding dividends.
According to GMGN data, WTH currently has a market cap of $6.4 million.
Programmable (@ProgrammableHQ)
Programmable is a token and custom project launch platform based on Uniswap v4, offering a no-code modular launch method as well as custom launch interfaces for developers. The platform currently supports Ethereum mainnet and Robinhood Chain.
The platform mainly provides two paths:
The first is Module Mode: select compatible modules on the website and configure parameters, without needing to write a complete smart contract yourself.
The second is Custom Launch: developers can use their own tokens, Hooks, or other supporting contracts to prepare a project launch through the API.
Both it and Hookr are lowering the barrier to deploying customized markets. For platforms like this, long-term competitiveness may depend more on module quality, integration capabilities, and actual usage rather than short-term issuance volume.
As of the time of writing, among tokens issued through Programmable, sorted by market cap, Claus (see introduction below) has reached a market cap of $6.42 million, Programmable's official token V4 on Robinhood Chain currently has a market cap of about $4.64 million, and another project, Temo, has a market cap of $450,000.
Claus
Claus (CLAUS) is an experimental project built on Ethereum Uniswap v4 Hook. Its core feature is that after token issuance, functions can be added, modified, or removed by updating the Hook contract without needing to reissue the token. The CLAUS token was issued through Programmable.
Fables
Fables Finance is a decentralized exchange built on Robinhood Chain using Uniswap v4 Hook, combining a ve(3,3) token economic model with programmable trading pool mechanisms, aiming to improve the flexibility of liquidity incentives and trading fee distribution.
Its core feature is using Hook to set dynamic fees for different trading pools, adjusting trading fees based on conditions such as market volatility to improve the return structure for liquidity providers. At the same time, Fables introduces a ve(3,3) mechanism, combining token locking, governance voting, and liquidity incentives so that participants can influence incentive distribution.

The Standard Reserve
The Standard Reserve uses Hook for an onchain monetary policy experiment. Its designated ETH/STANDARD trading pool tracks net ETH flows, and the "central bank" contract adjusts issuance accordingly: sustained inflows correspond to issuance expansion and reserve accumulation, while outflows correspond to issuance contraction, combined with a buyback-and-burn mechanism.
According to GMGN data, the STANDARD token currently has a market cap of $26.17 million.

Bordrless
Bordrless needs separate clarification: it uses a self-developed Hook mechanism on Solana and is not directly built on Uniswap v4 Hook.
It builds its own token standard, DEX, and launch platform on Solana, allowing developers to write custom rules for actions such as token transfers, minting, burning, and trading.
For example, developers can design a mechanism in which, when a token trade occurs, part of the amount automatically enters a designated account and part of the tokens are burned; fee rules can also be changed based on conditions such as holding time and market state.
The idea is to give tokens themselves richer programmable capabilities while using a supporting DEX and Launchpad to host trading and issuance activity.
As of the time of writing, among tokens issued through Bordrless Launchpad, only 2 are between $100,000 and $200,000 in market cap, while the rest are in the thousands to tens of thousands of dollars.
According to GMGN data, the Bordrless token BORDR currently has a market cap of $6.4 million.
Conclusion
From these product paths, it can be seen that Hook is enabling trading pools to take on more functions: combining issuance rules, distributing arbitrage profits, reserve mechanisms, providing governance signals, and responding to the market risks of different assets.
What is more worth watching next is whether custom rules create real value, whether external users or projects are willing to keep using them, and whether these usage activities can generate verifiable protocol revenue.
There may be more and more projects that can write Hooks, but projects that can build real businesses with Hooks still need time to be filtered out.
