[SIMD-LAUNCH]
[SIMD-LAUNCH] Token name: SIMDTEST Token symbol: SIMDTEST SIMDTEST is launched as a standard 1,000,000,000 token (18 decimals) complying with Identity.md's standard token, with no transfer taxes or hooks at token-level. 90% of supply seeds the Uniswap v4 pool paired with IMD (0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7). The pool fee is fixed at 1.25% with no dynamic changes. CONTRACT: SIMDTESTHook (the launch pool's hook) 1. Immutable constants: - ANTI_SNIPE_MAX_FEE_BPS: 3000 (30%) starting swap fee on the paired currency taken during the first 10 blocks post pool open. - ANTI_SNIPE_DURATION_BLOCKS: 10 blocks during which the anti-snipe fee linearly decays from 30% to 0%. - MAX_BUY_BPS: 100 (1% of total token supply) as maximum tokens bought per single swap during the first 60 minutes. - MAX_BUY_DURATION_SECONDS: 3600 seconds (1 hour) after pool open. - SWEEP_TREASURY: 0x3dd5f73dd1a4e62630fad3909673f130ad429985 (SIMD Hackathon vault) receives accrued anti-snipe fees in IMD. - POOL_MANAGER: 0x000000000004444c5dc75cB358380D2e3dE08A90 (Uniswap v4 PoolManager). 2. Fee mechanics: - The anti-snipe fee applies only on token buys during first 10 blocks: it is charged on the paired currency side in beforeSwap via return deltas and accrued in the hook. - Fees are not swapped or burned inside the hook. - Anyone can call sweep() to transfer accrued IMD fees to the treasury. 3. Swap limits: - After each swap, read BalanceDelta for the launched token delivered. - If the swap occurs within 3600s from pool initialization and delivered tokens exceed 1% of total supply, revert with MaxBuyExceeded. - Limit applies per swap, no wallet-level enforcement. 4. Views: - limitActive() returns true during max buy interval. - maxBuy() returns fixed 1% token supply limit. 5. Access control: - No owner or admin functions; all parameters immutable. TOKEN: Standard 1,000,000,000 SIMDTEST tokens minted to deployer; 18 decimals; no custom logic; plain transfers. TESTS AND REVIEW: 1. Validate anti-snipe fee applies and decreases linearly from 30% to 0% across first 10 blocks post pool open, fees accrue in the hook. 2. Confirm sweep() transfers accrued IMD fees correctly to the treasury. 3. Attempt swap that buys exactly 1% tokens within 60 minutes succeeds; attempt exceeding 1% reverts. 4. Confirm no fees or restrictions after anti-snipe period and max buy window expires. 5. Mainnet-fork tests with real IMD token and PoolManager address for fee and max buy enforcement. 6. Adversarial security audit covering reentrancy, correct fee accounting, and no owner privileges. This launch ensures a fair vesting-free token launch with strong anti-snipe protection and swap-size buy limits enforced at the pool level via Uniswap v4 hooks, maximizing transparency and aligning with SIMD Launchpad's immutable, ownerless launch standards. 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. - Contracts: SIMDTESTHook. 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 (chainId 1). Uniswap v4 PoolManager: 0x000000000004444c5dc75cB358380D2e3dE08A90 (pass it to the hook constructor). - 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 buy above the max-buy limit while that limit is active (revert with MaxBuyExceeded; that is the intended launch rule), and 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. These are 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. - launch.json pool: pairedCurrency 0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7, fee 12500, tickSpacing 60, initialPrice "79228162514264337593543950336" (provenance only; the launch factory sets the opening price from the economics).
