Anti-Snipe Hook

Every Tripools pool attaches the same contract, TripoolsAntiSnipeHook. The Uniswap v4 pool itself carries fee = 0 — all tax is collected actively by the hook on each swap, always from the native ETH leg so creator and treasury revenue settles in ETH without token-side conversion.

Dynamic trading tax

You choose a base tax between 1% and 10% at launch. The hook cycles that rate against fixed tiers on every trade, keyed off a per-token buy/sell counter shared across all wallets:

• Buys (repeats every 4): base, base, 4%, 2%
• Sells (repeats every 6): base, base, 10%, 4%, 3%, 2%

Ordinary buy/sell tax splits 80% to the creator (accrued in TripoolsFeeLocker, claimable anytime) and 20% to the protocol treasury (sent immediately in the same transaction).

Anti-snipe protection

For the first 6 seconds after a pool goes live, any non-whitelisted buy pays a flat 50% tax instead of the tiered rate. Unlike ordinary tax, this snipe tax is never split: 100% goes to the protocol treasury. It's a bot deterrent, not creator revenue. Sniped buys still advance the buy counter.

Creators can whitelist up to 20 wallets before launch to trade normally from block one. The whitelist is immutable once the token is live.

Dev buy exemption

The factory's atomic dev buy at launch is exempt from hook tax entirely (sender == factory). Dev buys are hard-capped at 5% of total supply on chain.

Burned liquidity

Every launch position NFT is minted to TripoolsLpBurner and transferred to the canonical dead address in the same transaction. The pool is permanent from block one — nothing to migrate, unlock, or rug.

Coming soon: hook templates

Tripools is building a library of selectable hook templates so creators can pick alternate tax curves, vesting-aware transfer rules, or different liquidity behavior at launch. Today's shared anti-snipe hook is the only option until that library ships. See the roadmap for timing.
