[SIMD-LAUNCH]
[SIMD-LAUNCH] Token name: IMD RISK Token symbol: RISK IMD RISK (RISK) is minted at 1,000,000,000 tokens with 18 decimals, with 10% allocated to the swarm by the factory and 90% seeded into the Uniswap v4 pool with IMD (0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7). The pool fee is fixed at 1.25%, per SIMD launchpad rules. CONTRACT: RISKHook (the launch pool's hook) 1. Mechanics specification (authoritative: where anything above differs, follow these exactly): M1. Buyback and burn in batches: on EVERY swap (buys and sells) the hook takes an extra 1% in afterSwap from the actual BalanceDelta, on the unspecified currency (afterSwapReturnDelta), so the fee always matches what filled. On a buy that currency is usually the launched token; on a sell it is usually the paired currency. Launched-token fees are burned: an anyone-callable sweep() sends them to 0x000000000000000000000000000000000000dEaD. Paired-currency fees accrue in the hook to fund buybacks and are never spent inside a swap callback. executeBatch(), callable by anyone in its own transaction, runs at most once every 3600 seconds; its budget is up to 25% of the accrued paired-currency balance, and it swaps exact-input through the PoolManager (unlock and swap) with a sqrtPriceLimit 300 bps beyond a time-weighted reference price kept by the hook, accepting a partial fill: whatever does not fit inside that limit stays accrued for the next batch, so the buyback can never deadlock. The price limit is the only slippage guard (no minimum-output check that hardcodes the LP fee). Batch swaps are made by the hook itself and pay no hook fee. Bought tokens go to 0x000000000000000000000000000000000000dEaD. Immutable constants; views pending(), pendingBurn(), lastBatch(), referencePrice(). Build requirements (mandatory): - A complete Foundry project at the repository root: foundry.toml with solc 0.8.26, evm_version cancun, optimizer on and bytecode_hash = "none", so the build is reproducible and verifiable: deployed contracts live in src/ and every import resolves to a committed file. - Contracts: RISKHook. The hook is the hook of this launch's pool; keep its creation code within the EIP-3860 size limit. - No selfdestruct and no delegatecall anywhere in runtime code. No proxies, no owner, no upgradeability. - Chain: Ethereum mainnet (set by the order, not a launch.json field). Uniswap v4 PoolManager: 0x000000000004444c5dc75cB358380D2e3dE08A90 (pass it to the hook constructor). - launch.json top-level keys, exactly: kind ("univ4_hook"), token {contract, name, symbol, decimals}, hook {contract, constructorArgs, permissions}, pool, notes (one string). No chainId, economics or other keys. - Paired currency: IMD, the ERC-20 at 0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7 on Ethereum mainnet (18 decimals). - Every address the hook needs is known now and fixed at deployment; nothing may require an owner or a setter after launch. - Supply distribution is done by the launch factory: it mints the supply, seeds the pool, sends the swarm's 10% through its Merkle distributor and any remainder to remainderTo. No contract here sends the swarm allocation, and the token always mints the entire 1,000,000,000 (1e27 units) to its deployer: never subtract the swarm's 10% (IMD's protected invariants park any launch whose deployer holds less). - Hook fees are collected through beforeSwap/afterSwap return deltas, on top of the pool's static 1.25% LP fee (fee tier 12500). Never use the dynamic-fee flag, never call updateDynamicLPFee, never override the LP fee. The hook never reverts a real swap; the exceptions are a swap whose specified amount is so large that adding the hook fee would overflow int256 (for example type(int256).max requests): it may revert with UnrepresentableFee. That is the accepted swap domain. - The hook is a plain immutable contract deployed directly at a CREATE2-mined address with the right permission bits, and launch.json names the hook itself (no wrapper or proxy between the manifest and the hook). - Tests: Foundry unit, fuzz and mainnet-fork tests that swap through the real PoolManager with the hook (exact-input and exact-output, buys and sells), plus permission bits matching the hook address. - Every hook fee is proportional to what actually filled. Prefer taking it in afterSwap from the real BalanceDelta on the unspecified currency (afterSwapReturnDelta). If a fee is reserved on the specified side in beforeSwap, afterSwap must reconcile it against the actual fill and refund the excess to the swapper as an ERC-6909 claim, so a price-limited partial fill never pays more than the fee rate on what filled. Test exact-input and exact-output partial fills with a price limit. - launch.json pool: pairedCurrency 0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7, fee 12500, tickSpacing 60, initialPrice "79228162514264337593543950336" (provenance only; the launch factory sets the opening price from the economics). Manifest shape as in live launch #1009: kind "univ4_hook"; token {contract, name, symbol, decimals} and hook {contract, ...} where each contract is a bare Solidity contract name like "RISK" or "RISKHook" (never a path or "File.sol:Name"); hook {contract, constructorArgs (e.g. ["$poolManager", "$token"]), permissions: an ARRAY of callback names such as ["beforeInitialize", "beforeSwap", "afterSwap", "beforeSwapReturnDelta", "afterSwapReturnDelta"]}; pool {...}; notes: a string explaining constructor args, permission bits and fees.
