Questions

What is Hookr.fun?

Modular infrastructure for surfacing, composing and integrating custom Uniswap hooks. Launch tokens, manage liquidity, or build and list hooks of your own. On Robinhood Chain 4663, new-token launches use a permissionless, pool-first launch model familiar from pools.trade with the current inspectable Uniswap v4 hook blocks, with more sealing over time. The hook marketplace pays the recorded author when another launch uses their hook. Every rule is readable before trading. Hookr is independent and is not affiliated with pools.trade.

What rules can a pool run today?

Today's rules, with more sealing as new modules and profiles land: Anti-Snipe caps and taxes opening buys. Surge Fees scales with trade size. Auto Burn sends buy output to the dead address. LP Rewards pays in-range LPs. Nth-buy Pot pays the Nth qualifying buy.

Is the Nth-buy Pot random?

No, the pot is not random. A public counter advances at most once per pool per block, and the Nth qualifying slot wins, arithmetic anyone can check on chain. A minimum buy applies, and claimants can redirect their payout.

Where do Hookr tokens trade?

A new token opens in its own Uniswap v4 pool on the Hookr root hook, in one transaction, at a fixed 2.5 ETH opening valuation or its equivalent in the quote you pick, with the rules you chose frozen into it. An existing asset gets a hooked pool of its own. Trades route through the Hookr router or Uniswap's Universal Router, and the Uniswap interface routes through these pools because the root hook is on its allowlist. Tokens launched on earlier generations keep trading in their original pools.

Can I attach a hook to a token that already trades?

Yes. The existing-asset lane opens a new hooked Uniswap v4 pool for a token that already trades, with zero liquidity, no founding position and no power over the token. The launchpad's own pool keeps running; a v4 pool's hook is fixed when that pool is created, so the hook lives on the new pool, not the old one.

Can a pool hold a tokenized stock?

Yes. Any asset with code on Robinhood Chain can be the subject or the quote of a hooked pool, including Robinhood's tokenized stocks. The pool inherits the stock's pause registry, so a pause of that token halts the pool. Most creators put the stock on the quote side and keep auto burn off it, because burning a stock destroys a claim on a real share.

What is the official Hookr X (Twitter) account?

@hookrfun, https://x.com/hookrfun. Verify links before connecting a wallet; an address plus its chain, not a ticker or a handle, is a token's identity.

What is the $HOOKR contract address?

The source-listed $HOOKR project token is 0x18E674231A58c239Dc7DaeDcffE15Ec3A24cff5c on Robinhood Chain 4663. Always verify the full address before trading. Its listed market is a hookless Uniswap v4 pool. The app verifies the token's launchpad relation at a pinned block before showing project-token market or trade UI; an unavailable result is never inferred as either outcome.
