Hookr

Hookr is modular infrastructure for discovering, composing, and integrating custom hooks for Uniswap v4 on Robinhood Chain. It lets users launch or open pools with selectable Hook Blocks, provide and manage liquidity, and access hooks through a public catalog, software development kit (SDK), JSON routes, and signed packets for agents.^[1]​

Overview

Hookr is a decentralized finance (DeFi) platform built on Uniswap v4 that enables users to launch tokens, create liquidity pools, and customize trading functionality through modular components called Hook Blocks. The platform allows creators to combine features such as dynamic trading fees, token burns, and liquidity provider rewards, with settings established when a pool is created. It also supports pools for existing assets, integrations with third-party launchpads, and a review process for community-developed Hook Blocks. In addition, Hookr provides a revenue-tokenization system that allows users to lock fee-generating assets or positions and issue tokens representing claims on the resulting income. ^[3]

Hook Blocks

Hook Blocks are configurable features that creators combine for a particular pool. Their functions include changing swap fees, distributing fees to liquidity providers, limiting trading behavior, and directing value to designated recipients.^[1]​^[2]​

The listed blocks include:

• Anti-Snipe caps early buys and adds a liquidity-provider fee during the first blocks; Dynamic Fees scales fees according to how far a swap moves the price; and Auto Burn burns a share of the actual output from buys.^[1]
• LP Rewards streams a share of fees to liquidity providers; Arb Recapture directs arbitrage value to the pool rather than outside maximum extractable value (MEV) bots; and Buy/Sell Block prevents the same trader from buying and selling in the same block.^[1]
• Market Guard charges a surcharge, paid to liquidity providers, when a swap deviates from a live Chainlink price. Recovery Reserve provides a publicly visible, owner-funded reserve that anyone can top up and that can compensate liquidity providers or traders after a reviewed incident.^[1]
• Canonical Venue Token restricts a token to trading on its own pool. Tax + Conversion imposes buy and sell taxes paid in the pool’s quote asset. Creator Royalty assigns a share of LP Rewards to a recipient fixed at launch, while Revenue Router divides a royalty among as many as eight payees, also fixed at launch.^[1]
• Swap Reward Mint pays traders in reward tokens funded by part of a trade. Pay Later lets buyers pay a premium for a later purchase at a fixed price, and Entry Ratio Guarantee lets liquidity providers lock in entry amounts using their fees.^[1]
• Floor Bid maintains a treasury bid below the market price. Vesting Milestone locks a team allocation through a cliff followed by linear vesting. Zap Relay source routes part of each buy to a zap vault that buys another pool; Zap Relay target allows purchases only from designated source pools while still permitting anyone to sell.^[1]
• Limit Orders escrows a trade at a set price so anyone can fill it when the pool reaches that price. Best Route compares Uniswap pools and offers a better route only when it clearly beats the pool. The Hook Blocks Market lets builders publish add-on blocks bonded in HOOKR; pools using those blocks pay a usage fee on each swap.^[1]

Hookr describes What The Hook as live on its platform and says it runs Arb Recapture on Hookr pools. Its site also states that What The Hook’s Arb Recapture block was not yet available for new pools.^[1]​^[3]​

Fees and Revenue Distribution

Hookr’s fee model distinguishes the base liquidity-provider fee from fees generated by Hook Blocks. The base LP fee goes entirely to liquidity providers. A pool creator sets the share of Hook Block fees, with 20% as the default and a permitted range of 20% to 50%; the remainder may go to liquidity providers, a burn, or a tax recipient, depending on the block. Hookr describes the default division as 80/20 between liquidity providers and the relevant Hook Block fee share.^[1]​^[4]​^[2]​

A pool whose token otherwise pays Hookr nothing is subject to a minimum Hookr share currently set at 0.1% of each swap. Another payment to Hookr replaces that minimum. Hookr says its own shared hook carries a 0% fee, while a charge of 5% of supply applies off that hook.^[1]​^[2]​^[4]​

For Arb Recapture, Hookr describes a 25% share for itself and up to 25% for What The Hook, with the remainder going to the pool. Its token information says What The Hook takes 25% of recaptured profit, while another 50% goes to the trader and liquidity providers in proportions set by the creator at launch, or to the pot on King of the Pool pools.^[1]​^[4]​

Fee-Rights Tokenization

Hookr’s fee-right product lets a user lock an income-producing fee right and mint a fixed supply of revenue tokens whose holders share its income. The product can be used with launch fees, Uniswap positions, and pools.trade fee non-fungible tokens; users can also tokenize assets held in their wallets. Each swap in a tokenized pool pays the revenue-token holders, the token has its own market at mint, and users can send any token to all holders as a “drop.” The original fee right returns when its term ends.^[1]​^[3]​

Add-ons include Time shares, which sell one day of income, and Compound, which directs income back into the token’s pool. Hookr listed income advances, automations, and borrowing against revenue tokens as forthcoming features. Revenue tokens take 0% or 5% of supply depending on whether all revenue streams run through the Hookr hook: the 0% rate applies when they do, and the 5% rate when any stream does not.^[1]​^[4]​

Tokenomics

$HOOKR is Hookr’s utility token on Robinhood Chain. CoinMarketCap and CoinGecko list its circulating, total, and maximum supply as 1 billion HOOKR.^[5]​^[6]​

Hookr says protocol revenue shares are swept to its treasury to buy back HOOKR, which is then burned; the treasury executes the burns, which are visible at the dead address.^[4]​

Ecosystem

Hookr lists What The Hook as live and identifies StonkBrokers’ Battle, Strategy, Fractional 404, and Smart LP as official Uniswap v4 hooks available on the platform. It also says the Uniswap app and API can route swaps through pools on Hookr’s default root. Other named projects or integrations include Saffron, ZEAL, Longbow, OPEN, PumpPill, Hood Domains, rhook, VolaDelta, V4RCADE, and PARE.^[1]​

Hookr says its catalog includes Uniswap v4 hooks that have been analyzed and reviewed. Its integrations documentation distinguishes projects that are live on Hookr, community integrations, and those marked as coming soon; community integrations are built and operated by their own teams and are not presented as Hookr endorsements. The documentation also identifies Fomo as a trading venue linked from token pages.^[1]​^[3]​
