# Hookr.fun

> Modular infrastructure for surfacing, composing and integrating custom Uniswap hooks. Explore active Uniswap v4 pools, analyze their hooks, and create new hooked pools from one app.
> Hookr runs on Robinhood Chain (chain id 4663). New pools open on Hookr: one Uniswap v4 hook, HookrRoot, with the Hook Blocks you choose for each pool, or a hook of your own that runs the same Hook Blocks.
> Liquidity providers keep the whole base LP fee. Hookr is independent and is not affiliated with pools.trade. Every Hook Block and every protocol share is readable on chain before trading. The checked-in release manifest, not this summary, determines which writes are enabled.

Hookr also publishes plain-language explainers for the topics this protocol is built on:
automated market makers (AMMs), liquidity providers (LPs), Uniswap v4 hooks, bonding curves,
token launchpads, zero-seed Instant Launches, Continuous Clearing Auctions, and reading onchain
markets.

- [Full machine-readable product reference](https://hookr.fun/llms-full.txt): release boundaries,
  every public page with its summary, dynamic-page admission rules, data provenance, and agent citation guidance
- [Agent skill file](https://hookr.fun/agents/SKILL.md): a self-contained markdown file an
  autonomous agent reads directly, under 8 KB: deployed addresses, pool derivation, router
  encoding, calls, and safety checks for reading, trading, launching, and claiming on Hookr pools;
  no account or key required. See [Get Hookr for your agent](https://hookr.fun/agents).
- [Hookr MCP server](https://hookr.fun/docs/mcp): a remote MCP server at https://hookr.fun/api/mcp (Streamable HTTP, POST only, no key). Eleven tools find pools, quote, check a trade and build swap, claim and launch calls; the wallet signs, the server never sends.

## What you can do on Hookr

- Build a hook: plug [Hook Blocks](https://hookr.fun/hooks) into a Uniswap v4 hook in the [builder](https://hookr.fun/builder) and set each one within the contracts' bounds.
- Run it two ways: on Hookr's shared hook, HookrRoot, with nothing to deploy, or deploy your own hook that runs the same Hook Blocks ([owned roots](https://hookr.fun/docs/pools/owned-roots)).
- Open pools: one token in one to eight pools, each with its own quote and Hook Blocks, or new pools for a token that already trades ([Launch](https://hookr.fun/launch)).
- Compete for a pot: [King of the Pool](https://hookr.fun/kings) gives the biggest buy of each round the whole pot that arb recapture fills.
- Follow a worked setup: [HookrBook](https://hookr.fun/docs/hookrbook) gives twenty-eight ways to put pools together and every builder step of each one.
- Integrate: launchers, interfaces and executors start at the [integration guides](https://hookr.fun/integrations), the [SDK](https://hookr.fun/docs/pools/sdk) and the [partner review](https://hookr.fun/integrate/hooks).

## Revenue tokens

A revenue token is a fixed-supply ERC-20 with a fee right locked behind it; its holders share the fee right's income, released over the token's release period and claimable whenever they like. The HookRevenue Tokenizer on Robinhood Chain makes them, with no owner.

- Contract ABI API: `GET https://hookr.fun/api/v2-abi/{ContractName}`: the published ABI of a contract that earlier pools run on, as plain JSON; the names are on [Previous releases](https://hookr.fun/docs/previous-releases#abis-and-errors)

- robots.txt: https://hookr.fun/robots.txt: public pages and discovery documents are crawlable by search and AI crawlers; the read-only JSON routes named here are crawlable too; account, authentication, and operator surfaces are excluded
- security.txt: https://hookr.fun/.well-known/security.txt: canonical machine-readable security contact, policy, expiry and official identity
- Dynamic launch pages: `https://hookr.fun/t/{address}` are indexable only after a live registry read proves exactly one owning Hookr release
- Dynamic creator pages: `https://hookr.fun/u/{address}` are indexable only with public profile or registry evidence
- Project-token pages: `https://hookr.fun/project/{address}` are indexable only for source-listed project tokens
- Dynamic hook-analysis reports: `https://hookr.fun/analyze/report/{address}` title as "<hook name or short address> hook report"; a failed or incomplete read still renders, unindexed, rather than fabricating a score

## Official links

- Website: https://hookr.fun
- X (Twitter): https://x.com/hookrfun (@hookrfun) is the only official Hookr account. Hookr recovered and confirmed control of it on August 25, 2026.
- The only $HOOKR contract we have issued is 0x18E674231A58c239Dc7DaeDcffE15Ec3A24cff5c on Robinhood Chain (4663). Any other contract or chain is not ours.
- Verify any address on chain before trading; an address plus its chain, not a ticker or a handle, is a token's identity.

## Facts worth quoting precisely

- On Hookr, liquidity providers keep the base LP fee in full. Hookr's share is 20% by default and never above 50% of the Snipe tax, dynamic fee, LP Rewards and Auto Burn a pool opts into, plus 25% of each arb recapture profit. A pool for a token launched on Hookr that pays Hookr none of these pays a minimum instead, 0.1% of each swap now.
- Arb recapture: What The Hook's executor runs the arb recapture, and if it cannot, the trade goes through without it. Each profit splits 25% to What The Hook's executor, 25% to Hookr and 50% to the pool. With King of the Pool on, the pool's half fills a pot, and the biggest buy of each round takes the whole pot. ETH/HOOKR runs King of the Pool.
- Two ways to run a hook: Hookr's shared hook, HookrRoot, or a hook you deploy that runs the same Hook Blocks. A pool's hook is fixed when it opens.
- Wallet Cap: while a pool's launch guard lasts, no wallet can buy more than a set share of the token's supply, counted across every pool of the launch against the wallet that pays. It runs on a core of its own on Hookr's hook, and it limits each paying wallet, not each person.
- A Hookr pool's quote is native ETH, one of the 22 catalog assets the registry lists, a Robinhood stock token or, shown as unreviewed, any other token. Each pool keeps its quote for life.
- A Hookr pool's Hook Blocks are frozen when it opens; nobody can change them later.
- Token identity is the contract address plus chain, never the ticker alone.

## Previous releases

- [Previous Hookr releases and their contracts](https://hookr.fun/docs/previous-releases): The contracts, launch generations and SDK that came before Hookr's current contracts, and the pools that still run on them.
- On earlier pools, the native-mechanics chassis took no flat protocol fee and no share of the base LP fee. Its protocol share, 20% by default and never above 50%, came only from the add-ons a pool opted into (dynamic fees, a snipe tax during the launch guard, LP rewards, an Nth-buy pot, and an auto-burn).
- Generation 5 offers a fixed-price, zero-seed Instant Launch lane and a bonded Auction Launch lane using a Uniswap Continuous Clearing Auction; accepted bids in a clearing block receive that block's clearing price.
- An auction below its disclosed raise floor refunds every bid, burns the supply, and opens no pool.
- Generation-5 launches can pair with ETH or the canonical $HOOKR token. ETH-paired swaps accrue the promoted 0.30% flywheel fee; $HOOKR-paired launches do not charge that protocol fee.
- Anyone may collect accrued ETH-pair fees into the flywheel burner; only its owner may execute a per-call-capped, once-per-block buyback with a reviewed minimum $HOOKR output, and bought $HOOKR is sent to the dead address.
- Generation 3 and 4 launches remain readable with their original mechanics. Their bonding curve sold ten tranches, each priced 70% above the previous tranche, and graduated into a Uniswap v4 pool in the final tranche transaction.
- The Nth-buy Pot, on earlier pools only, is not random: a public counter advances at most once per pool per block, and the Nth qualifying slot wins.
- Flywheel Burn is live under the promoted generation-5 release.
