Anti-whale + cooldown + pausable — the three protections that matter on launch day.
Memecoins die in the first ten minutes when sniper bots eat the initial liquidity pool. This preset bundles three on-chain protections that disrupt the sniping economics without the full Fair-Launch lockdown. Anti-whale caps how much any single wallet can buy in the first hour; cooldown forces a delay between same-wallet transfers; pausable is the panic switch if something pathological happens.
Anti-whale + cooldown together make sniper-bot arbitrage unprofitable in the first window — they have to spread purchases across many wallets and many blocks, which destroys their gas economics. Pausable is the emergency button for the (rare but real) case where the LP gets exploited mid-launch. The supply stays fixed at deploy so what you announce is what trades.
Fair-Launch bundles six modules: anti-whale + cooldown + rate-limit + max-holders + freezable + pausable. Memecoin keeps just the three that matter on launch day. The other three (rate-limit, max-holders, freezable) add real overhead and are most useful when you want a long-term gated community — overkill for a memecoin that wants free trading after the first hour.
Anti-whale and cooldown rely on the EVM module pattern — _update() overrides on the ERC-20 base that intercept every transfer and run pre-checks. Solana SPL and Sui Coin<T> don't expose an equivalent interception surface, so the per-tx checks have no home on those chains. Fair-Launch (the six-module sibling preset) is EVM-only for the same reason.
Yes — each module has a manage-page toggle. Most teams keep the protections on for the first 24–72 hours and disable them once the order book stabilises. Pausable can stay enabled indefinitely as a kill-switch even after anti-whale and cooldown are off.
