Caps early buys and adds an LP fee in the first blocks.

Pair it carefully with the Nth-buy Pot: on a small raise the guard's ETH ceiling can land below the pot's minimum qualifying buy, and during the window no buy can both qualify for the pot and pass the guard. The builder surfaces that conflict before launch instead of letting it ship.
Source verification is not an independent audit.Anti-Snipe: max 0.5% total buys per pool block + 40% tax for the first 100 blocks
Stacks with any of the other native blocks in one custom hook; the builder checks parameter conflicts, like the anti-snipe guard against the Nth-buy pot, before it lets you deploy.
Not contract-backed. Native blocks carry no royalty; the builder composes them free of charge.
For a set number of blocks after the pool opens, cumulative buys in each pool block are capped, pay an extra LP fee that goes to LPs, and cannot be routed around with an exact-output buy. The cap basis comes from the launch record: total supply for V1 lanes and retained curve launches, or the placed float on an earlier instant pool.
Blocks after the pool opens with sniper protection active. Counted in the parent-chain blocks the contracts see (~12 s each), not this chain's ~0.1 s blocks, so 100 is roughly 20 minutes.
Cumulative cap on all buys in one pool block during the guard window, derived from a share of the launch's supply basis. Splitting one order does not create more room in that block.
Extra LP fee on swaps inside the guard window. Goes to LPs.
