When the hook acts: after every swap (afterSwap), plus once at pool initialization (beforeInitialize) to lock the hook to this launch's pool. Fee rule: the hook takes no fee. No fees, only the launchpad's standard trading fee (LP fee 12500, 1.25%). Where fees go: nowhere; the hook never takes or moves any funds. Who can change it: nobody. No owner, no admin, no upgrades, no settings. Token name: Pixel Pool Token symbol: PIXEL Build PIXEL POOL on Ethereum mainnet, kind univ4_hook, paired with IMD (0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7): the launch token and its Uniswap v4 pool with our hook, which paints a 32x32 dot canvas on chain, one dot per swap. TOKEN PixelToken (src/PixelToken.sol): plain ERC20, name "Pixel Pool", symbol "PIXEL", 18 decimals, no constructor arguments, fixed supply 10^27 units minted once to its deployer, ordinary transfers, no mint, tax, owner or proxy. HOOK PixelPoolHook (src/PixelPoolHook.sol, Solidity 0.8.26, Foundry, depends only on v4-core): 1. Implements IHooks directly. Constructor(IPoolManager manager, address token) in that order; validates permissions with Hooks.validateHookPermissions. Permissions: beforeInitialize and afterSwap only (address mask 0x2040). No return deltas, never touches funds. 2. beforeInitialize: only the PoolManager, only once, only for the pool of this hook with the launch token and IMD; stores poolId and quoteIsCurrency0 (true when currency0 is not the launch token). Any later initialize reverts. Every enabled callback reverts unless msg.sender is the PoolManager; afterSwap reverts for any other pool. 3. afterSwap paints one dot: strokes += 1; pixel = (strokes - 1) % 1024. Dots fill in order, left to right, top to bottom; after 1024 swaps a new pass repaints from the top left. 4. Color: BUY = IMD in, PIXEL out (buy = zeroForOne == quoteIsCurrency0) is GREEN; SELL is RED. Shade by the absolute IMD amount of the swap delta: < 5, < 50, < 500, >= 500 IMD (18 decimals) -> index 0..3. Palette index: 0 empty, 1..4 green #1f7a3d #22b455 #2ee66b #8dffad, 5..8 red #7a1f1f #c42b2b #ff3b3b #ff9a9a, empty #0b0b12. 5. Storage: 1024 one-byte palette indexes packed 32 per slot in uint256[32], leftmost dot in the least significant byte of each row. 6. Event Painted(uint256 indexed stroke, uint256 indexed pixel, uint8 color, address indexed painter) with painter = tx.origin. 7. Views: strokes(), pixelAt(i), canvas() returning uint256[32], quoteIsCurrency0(), render() returning an SVG of the dots built in a preallocated buffer, under 15M gas on a full canvas. 8. No owner, admin, upgrade, pause or post deploy calls. Keep it small; no features beyond this spec. TESTS (Foundry, against a real v4 PoolManager): dots paint in order; buy green and sell red with IMD as currency0 AND as currency1; bigger swaps brighter; second pass repaints; only one pool; only PoolManager; render under the gas limit. Launch manifest: launch.json must be exactly this JSON: { "kind": "univ4_hook", "hook": { "contract": "PixelPoolHook", "constructorArgs": ["$poolManager", "$token"], "permissions": ["beforeInitialize", "afterSwap"] }, "token": { "contract": "PixelToken", "name": "Pixel Pool", "symbol": "PIXEL", "decimals": 18 }, "pool": { "pairedCurrency": "0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7", "fee": 12500, "tickSpacing": 60, "initialPrice": "79228162514264337593543950336" }, "notes": "PIXEL POOL on Ethereum mainnet paired with IMD. PixelPoolHook(IPoolManager $poolManager, address $token) has permissions beforeInitialize and afterSwap (mask 0x2040), no return deltas, no fee, no owner. Every swap paints one dot on a 32x32 on chain canvas in order: green for buys, red for sells, brighter for bigger IMD amounts; after 1024 swaps it repaints from the top. PixelToken has no constructor arguments, 18 decimals and a fixed 10^27 supply minted to its deployer. initialPrice 2^96 is the decimal sqrtPriceX96 for provenance; the launch economics set the actual opening price. Deploy the hook and initialize the pool in one transaction." }
