Buy overhead 0.80%Est gas 820K2 blocks
Royalty is the share of this stack's eligible ETH hook-fee routing sent to you when someone launches with your saved blueprint. Auto Burn destroys token output and does not fund royalties. Capped at 10% by the contract.

Tip: click a block in the stack to tune it. One block per behavior.
Not blocks · set per launch
Creator fee split and LP distribution are not part of a hook. A stack is reusable — anyone can launch with it — so it can only hold rules that are the same for every launch. Payout addresses and how the raise is placed as liquidity belong to a single launch.
You set both in the launcher, on step 3 · Price & fees.
A buy enters at the top, pays its cuts inside the chassis, and settles into the token's Uniswap v4 pool. Dashed sockets are open ports — click one to attach that block; click a placed block to tune it.
Anti-Snipe

100 BLK
Blocks after graduation with sniper protection active.
0.5% SUP
Per-swap buy cap during the guard window, as a share of supply.
40%
Extra LP fee on swaps inside the guard window. Goes to LPs.
Stack behavior
- Anti-Snipe: max 0.5% buys + 40% tax for the first 100 blocks
- Nth-buy Pot: 0.5% of buys, the public 500th slot wins
What this cannot do
- No per-person limits. The guard caps each swap, not each wallet — one buyer splitting across wallets is unaffected.
- No bot detection and no fairness guarantee. The guard caps each exact-input buy and adds a temporary buy tax, but a trader can split orders or wallets.
- No random draw. The Nth-buy pot follows a public counter, advances at most once per block, and stays claim-backed for the next scheduled winner. It has no permissionless flush.
- Auto Burn affects actual token output. Auto Burn and the LP / Nth-buy pot shares apply to exact-input buys only; sells and exact-output swaps skip them.
- Block order here is cosmetic. The deployed hook always runs its behaviors in the same fixed order.
- Buy overhead is what a buy costs: the base LP fee (0.3% by default, even with no fee block stacked), the ETH-side LP / pot cut, and any output burn composed multiplicatively. A sell pays the LP fee only, and surge can push that fee higher on large trades either way. Est gas is a rough client-side figure, not a simulation.
