Snipers love a fresh pool: bundle the first block, grab a huge bag, dump on your buyers. HyperPad’s anti-snipe guard lets you throttle that — a per-wallet cap for a short window right after trading opens.

​
What you set

Set either to a non-zero value and the guard turns on.

​
How it works

1

Trading starts closed

The token can’t be transferred between regular wallets until your sale settles and the LP is seeded — so no one can trade ahead of your buyers.
2

The cap bites pool buys

For antiSnipeBlocks blocks after trading opens, any transfer to a fresh wallet (a market buy out of the pool) is capped at maxWalletDuringGuard. The sale, your team wallet, the LP adapter, the factory, and the claim vault are all exempt — so claims and liquidity are never blocked.
3

The cap expires

Once the window passes, the token transfers freely with no restrictions. It’s a speed bump, not a permanent tax.

​
You can’t honeypot with it

The guard can throttle but it can’t trap. When the guard is on, the form sets a tradingAutoOpenAt backstop (default: sale end + 7 days). After that timestamp, anyone can call forceOpenTrading() — so even if something goes wrong with settlement, trading can always be opened permissionlessly. There’s no “trading disabled forever” state for a project to abuse.
