# Hookr.fun

> The hook launchpad for programmable markets. Deploy custom hooks and launch new tokens from one marketplace.
> Hookr runs on Robinhood Chain (chain id 4663). The hook marketplace lets creators publish
> reusable hooks and earn a royalty when another launch uses them.
> Generation 5 uses a permissionless, pool-first launch model familiar from pools.trade with up
> to five selectable hook blocks: Anti-Snipe, Surge Fees, Auto Burn, LP Rewards, and deterministic
> Nth-buy Pot. Hookr is independent and is not affiliated with pools.trade. Every rule is readable
> before trading. The checked-in release manifest, not this summary, determines which writes are
> enabled.
> Existing-token markets are designed as new v4 pools; that lane is not live yet. A v4 pool's hook
> is fixed at creation, so existing pools stay untouched. No deployed Hookr contract accepts an
> existing token's address today.

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.

## Learn — evergreen explainers

- [What is an automated market maker (AMM)?](https://hookr.fun/learn/what-is-an-amm): how AMMs price swaps from pooled reserves; constant product vs concentrated liquidity vs v4's singleton design
- [What is a liquidity provider (LP)?](https://hookr.fun/learn/what-is-a-liquidity-provider): earning swap fees, in-range liquidity, divergence loss, and how dynamic fees and LP rewards change the math
- [Uniswap v4 hooks, explained](https://hookr.fun/learn/uniswap-v4-hooks): what a hook contract is, how its address encodes permissions, what beforeSwap/afterSwap can do
- [What is a bonding curve?](https://hookr.fun/learn/what-is-a-bonding-curve): supply-priced tokens, tranche ladders, and graduation into an AMM pool
- [What is a token launchpad?](https://hookr.fun/learn/what-is-a-token-launchpad): what launchpads standardize, opening rules like anti-snipe windows, verifiable rules
- [What is Hookr's zero-seed Instant Launch?](https://hookr.fun/learn/instant-pool-launch): fixed opening valuation, no creator seed or token allocation, one locked token-only sell position
- [What is a Continuous Clearing Auction?](https://hookr.fun/learn/continuous-clearing-auction): budget and maximum-price bids, per-block clearing, successful migration, and failed-launch refunds
- [How do I read an onchain market?](https://hookr.fun/learn/reading-onchain-markets): identity by address plus chain, enforced rules, depth versus trade size, settled facts over displayed claims

## Product pages

- [Hookr.fun](https://hookr.fun/): product overview, current launch paths, hook blocks, safety boundaries, and frequently asked questions
- [Discover](https://hookr.fun/app): a bounded read of up to 60 registry entries per supported release, with UI-hidden canaries removed after the cap; filterable by pair currency, with lifecycle, USD FDV, holders, launch age, measured price change, and exact burn accounting. Market Pulse reports quote-separated, single-window flow concentration for the tradeable markets inside that same bounded set; incomplete reads remain explicit
- [Hookrs](https://hookr.fun/hookrs): wallet-backed Hookr profiles with launches, published hooks, hook reuse, and bounded claimable balances
- [Hook builder](https://hookr.fun/builder): build a custom hook from five onchain rules
- [Hook marketplace](https://hookr.fun/hooks): discover, publish, launch with, or remix reusable hooks
- [Anti-Snipe block](https://hookr.fun/hooks/anti-snipe): guard-window buy caps and snipe tax after the pool opens
- [Surge Fees block](https://hookr.fun/hooks/surge-fees): LP fee scales with trade size relative to pool depth
- [Auto Burn block](https://hookr.fun/hooks/auto-burn): a share of actual buy output goes to the dead address in-swap
- [LP Rewards block](https://hookr.fun/hooks/lp-rewards): an ETH-side share of buys donated to in-range LPs
- [Nth-buy Pot block](https://hookr.fun/hooks/nth-buy-pot): a deterministic pot paid by a public counter — not random
- [Launch](https://hookr.fun/launch): deploy a custom hook with a new fixed-supply token; preview the future existing-token lane without signing
- [$HOOKR token utilities](https://hookr.fun/token): twelve $HOOKR utilities — Flywheel Burn is live; Launch Boost and Lock Rewards remain receipt-backed but new writes are closed under the current release; nine remain labeled designs
- [Leveraged Hooks](https://hookr.fun/leverage): credit extended by a hooked market itself rather than a lending vault beside it. The first contracts (factory, hook, router) are live on Robinhood Chain 4663; the bonded module marketplace around them is a published design, not deployed
- [Leveraged Hooks, simply](https://hookr.fun/leverage/eli5): the same pool-native borrowing model and risk boundaries in plain language; contract deployment is separate from an available trading surface
- [Docs](https://hookr.fun/docs): instant and auction launches, retained historical curves, fees, hook blocks, and risks in plain language
- [Data & safety methodology](https://hookr.fun/methodology): source hierarchy, freshness boundaries, fail-closed displays
- [Market activity](https://hookr.fun/scan): selected launch, market, trade, burn, and hook events with receipt links

## Machine-readable data for agents

- Protocol stats API: `GET https://hookr.fun/api/protocol-stats` — unauthenticated JSON snapshot of block-pinned protocol metrics; cached ~5 minutes; returns HTTP 503 rather than fabricated numbers when reads fail
- Sitemap: https://hookr.fun/sitemap.xml — regenerated hourly; includes stable routes plus every registry-verified launch page at `/t/{address}` and creator profile at `/u/{address}`
- robots.txt: https://hookr.fun/robots.txt — public pages and discovery documents are crawlable; APIs are closed except the read-only protocol-stats endpoint; account, authentication, and operator surfaces are excluded
- 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

## Official links

- Website: https://hookr.fun
- X (Twitter): https://x.com/NodarJ (@NodarJ) is the only official Hookr account. The former @hookrfun account remains COMPROMISED and is not under our control; ignore every post, link, DM and token address from it.
- 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

- 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 is not random: a public counter advances at most once per pool per block, and the Nth qualifying slot wins.
- Token identity is the contract address plus chain, never the ticker alone.
- Flywheel Burn is live under the promoted generation-5 release. Launch Boost (0xb5cc450A1529A7CA3127C9065EFFa76144502BA5) and Lock Rewards (0x33f725e4a5094eDE37445A76bd96Ac9C8da94586) remain receipt-backed deployments, but new writes are closed under the current release gate. Nine other utility entries remain labeled designs — do not describe them as shipped.
- A Boost is a paid placement, not a yield position: the booster pays a 1% fee and their remaining principal is refundable to them after a tier timelock. The fee goes to $HOOKR lockers, not to boosters.
- Only the creator recorded for a token by the utility's supported generation-4 launchpad can fund that launch's Boost. New Boost writes are closed under the current generation-5 release gate.
- The first Leveraged Hooks contracts are live on Robinhood Chain 4663: factory 0xa8566BB5Ac3D91aaFdF6300e1b7321d057F10704, hook 0x81DEc5b02c546437b4D0e57211bd5632E67d7AC0, router 0x148bBc8BDa1012F9b37226527602E7A70f314175. The factory's createMarket is permissionless and mints each market's own fixed-supply token — it does not take an existing token's address.
- The bonded module marketplace around those contracts (module registry, bond vault, fee router) is NOT deployed — do not describe it as shipped. Leverage markets for tokens that already trade elsewhere are not possible on this factory generation.
- Under that design, credit capacity is the most conservative of market liquidity, executable liquidation depth, bonded $HOOKR and a protocol limit, so bonding more $HOOKR can never push a market's ceiling past what its liquidity supports.
- Providing liquidity to a leverage-enabled market means underwriting its credit: past the module reserve, bad debt falls on the market's liquidity providers.
