4mo LaunchGuardV4HookApplies a decaying sell tax on token-to-WETH swaps: starts at 99% and linearly decays to 2% over 194 minutes post-launch. Collected WETH accumulates in an on-hook reserve and can be compounded into locked liquidity every 8 hours via an authorized router, with a keeper reward of up to 0.005 ETH paid to the caller.

Blocks external LPs, enforces exact-input-only swaps with a 1% dynamic fee override, and automatically graduates the pool to a permanent full-range position once the graduation price tick is reached.

Includes an owner-configurable circuit breaker that halts swaps when the oracle's toxicity score exceeds a threshold; falls back to a base fee when oracle data is stale. Ethereum afterInitbeforeSwap 2 4mo DeadBuybackHookA Uniswap v4 hook for a WETH/DEAD token pool that charges a 5% WETH fee on buys and sells, splits fees 50/50 between a team wallet reserve and a buyback reserve, and automatically buys and burns DEAD tokens to address 0xdEaD every 15 taxed swaps.

Collects a 0.5% ETH tax on buys via beforeSwap delta and 1% on sells via afterSwap delta into a shared jar. Tracks a time-weighted "honey" score per holder; net sell pressure drains a strength buffer. When strength hits zero, a permissionless settle() distributes the ETH jar to non-selling holders proportional to their honey, then opens a new round. Ethereum beforeSwapafterSwapswapDeltaafterSwapDelta 2 4mo VoidHookDeflationary burn hook that intercepts buy swaps (ETH→VOID) in afterSwap, takes 0.1% of the VOID output from the pool manager, and burns it immediately. Sell swaps (VOID→ETH) are passed through without modification. Ethereum afterSwapafterSwapDelta 2 4mo PDAIBurnHookBurns 1% of pDAI on every swap in a WETH/pDAI Uniswap v4 pool. beforeSwap handles the specified side and afterSwap handles the unspecified side, each taking pDAI from the pool manager and sending it to address(0xdEaD) via return deltas. Burn failures are silently ignored so swaps always proceed. No admin, no upgrades, all addresses hardcoded.

Emits structured AgenticFlow and AgenticFeeQuoted events after each swap for external agents to consume.

Higher stress or volatility raises the fee to protect LPs; calm markets lower it. Emits telemetry in afterSwap for off-chain scoring.

Ethereum beforeSwapafterSwap 2 4mo HooksensorHookA dynamic-fee hook that reads quorum-verified Bittensor subnet stress scores and TAO price volatility from an on-chain EIP-712 bridge to set the LP fee on every swap (range: 1–5%, default 3% when no live reading). After each swap it emits telemetry events for off-chain oracle scoring.

In afterSwap, collects a 4% fee on exact-output swaps: ETH-out fees are split between token-holder dividends and the creator, while HASH-token-out fees go entirely to the creator.

When energy reaches 100% an "eruption" occurs, distributing the accumulated ETH reward pool proportionally to non-ashed token holders, then resetting energy and the round.
