Release gate closed · Robinhood Chain 4663Built on Uniswap v4 hooks
A token launchpadwith a customhook builder.
A token here sells along a bonding curve, and when the curve fills it graduates into a Uniswap v4 pool with your hook attached. The hook is up to five blocks — a guard window, a size-scaled fee, an output burn, an LP donation, a deterministic pot — and once the pool exists, none of them can be changed by anyone, including us. Writes are closed right now: the addresses below are the previous deployment, read-only, until the next release is verified on chain.

01The five blocks
What the hook actually does
Each block runs inside the swap, on the pool's own callbacks — there is no keeper, no off-chain trigger, and no oracle. Cuts apply to exact-input buys; sells pay the LP fee only. Every number below is a parameter you set before launch and nobody can set again afterwards. Source and simulation are not deployment proof, so writes stay closed until the exact addresses, bytecode, and canary results are verified on chain.

Pick the blocks.
Read the cost.
One block per behavior, five at most. As you tune the guard window, the pot cadence, or the burn share, the builder recomputes what a buy actually costs — the LP fee, the ETH-side cuts, and the output burn composed the way the contract composes them, not added up. It prepares a configuration for review; it does not deploy while writes are closed.

Open the builderHookr · how a buy is splitThe LP / pot ETH cut and Auto Burn apply to exact-input buys only. Auto Burn destroys its share of actual token output; it never accrues an ETH vault. Sells and exact-output buys pay the LP fee and nothing else.
The Nth-buy pot is deterministic: its public counter advances at most once per pool per block and the advertised Nth qualifying slot takes the pot. A funded pot remains claim-backed for the next scheduled winner; there is no permissionless flush. Qualifying buys must bind a canonical nonzero recipient, which the production router supplies automatically.

Compose a stack and inspect its eligible ETH fee routing. Publishing is currently closed. A future verified v3 release may fund blueprint royalties from LP and pot ETH cuts; an Auto-Burn-only stack has no ETH share to fund one.
