Introducing Hookr.fun: launchpad with custom Uniswap Hooks.
HOOKR TOKEN IS LIVE ON ROBINHOOD CHAIN: 0x18E674231A58c239Dc7DaeDcffE15Ec3A24cff5c
Hookr is a token launchpad for Robinhood Chain where the market rules are a Uniswap v4 hook you compose yourself.
When we started building Hookr, we made a bet: on a permissionless chain, the interesting part of a token launch is not the ticker — it is the market mechanics, and on every launchpad they are identical. Same pool, same fee, same opening chaos. So we built a launchpad where the pool’s behavior is the product.
Hookr is named for the Uniswap v4 hook — the contract a pool calls inside every swap. As of block 27,763,919 on Robinhood Chain, release generation 3 is live and writes are open: launching, blueprint publishing, and trading all work.
How it works:
You enter the token name, symbol, and image, and pick the ETH raise target for your curve — anywhere from 0.0001 to 1000 ETH. Metadata on Hookr is permissionless and not unique; a token is identified by its contract address, and the app says so everywhere rather than pretending otherwise.
You set your fee recipients — up to four, with balances credited automatically at collection — and your creator share of pool fees, from a 50 percent default up to 80 percent. The protocol always keeps at least 20 percent.
You compose the hook. Five blocks are available: Anti-Snipe caps each buy at a share of supply and adds an extra LP fee for your chosen number of blocks after graduation, with exact-output buys blocked so the cap cannot be routed around. Surge Fees scales the LP fee with how much in-range depth a trade consumes. Auto Burn sends a share of actual buy output to the dead address inside the swap. LP Rewards donates an ETH-side share of each buy to in-range LPs in that same swap. Nth-buy Pot fills a pot from an ETH-side share and pays the Nth qualifying buyer. Every parameter you choose is public on the token page before anyone buys. You can also launch from a blueprint — a saved configuration published by another designer, who earns a royalty from the stack’s hook fees when you use it.
You launch, for a flat creation fee (currently 0.0002 ETH). The token sells along a ten-tranche bonding curve: fixed supply of 1 billion, 80 percent on the curve, each tranche priced 70 percent above the last, with a 1 percent curve fee split between creator and protocol. Buys and sells both work on the curve.
When the curve fills, graduation is atomic. In one operation, the reserve ETH and the remaining supply become a full-range Uniswap v4 position owned by the launchpad, with your hook attached. The launchpad has no function to remove that liquidity — locked by construction, not by policy. LP fees on the locked position remain collectable and split creator/protocol; the token side of collected fees is burned. After graduation, nobody can retune the pool. Not you, not us.
We made a number of deliberate design decisions with Hookr, and we would rather state them — edges included — than have you discover them.
Mechanics inside the swap, not around it
First, every block runs on the pool’s own callbacks, inside the swap that triggers it. There is no keeper, no off-chain trigger, no oracle, no ETH vault waiting to be sandwiched. If a mechanic cannot survive being executed atomically in the open, we do not ship it.
Second, the floor is fixed so the mechanics can be flexible. Every launch gets the same curve math, the same atomic graduation, and the same permanently locked liquidity. Creativity lives in the hook; the floor is not negotiable.
Evidence over hype
Third, writes on Hookr are opened by evidence, not by a config flag. The release gate demands ordered deployment receipts, runtime code-hash readbacks, the hook’s exact permission flags, and user-confirmed canary transactions — a real launch-and-graduate, buy, approval, and sell — all re-verified against live RPC before the manifest flips. A production boolean alone cannot open writes. Our superseded first deployment remains public and readable on chain as the receipt of why this process exists.
Finally, the sharp edges are part of the product description. The pot is deterministic, not random — the counter is public, advances at most once per pool per block, and the next slot can be raced. Auto Burn sends tokens to the dead address but does not reduce the ERC-20 totalSupply readout. Hook cuts apply to exact-input buys only; sells pay the LP fee. And when a chain read fails, the app renders “unavailable” — never a fake zero.
This candor may cost us some hype. We think it buys something better: traders who know the rules of a pool before they enter it, and creators whose mechanics can be checked by anyone.
