[SIMD-LAUNCH]
[SIMD-LAUNCH] Token name: SIMDTEST Token symbol: SIMDTEST This launch deploys the SIMDTEST standard ERC-20 token (1 billion supply, 18 decimals, no taxes) and a Uniswap v4 hook named SIMDTESTHook that applies an additional dynamic fee on swaps in the paired IMD currency. The fee starts at 4000 basis points (40%) at pool initialization and linearly decreases with elapsed time to a steady-state fee of 300 bps (3%) after 3600 seconds (60 minutes). The pool fee remains constant at 12500 units (1.25%) per Uniswap v4 policy. The entire dynamic fee accrues in the hook contract, held in the paired currency (IMD), and can be swept by anyone to the immutable treasury address 0x3dd5f73dd1a4e62630fad3909673f130ad429985 supporting the SIMD Hackathon fund. No ownership or admin controls exist; all parameters, including fees and treasury, are constants fixed on deployment. The launch mints the full 1,000,000,000 tokens to the deployer; 90% of supply seeds the pool, with no remainder or burn address as all tokens are allocated to the pool. The hook exposes view functions feeNow(), openedAt(), pending(), and collected() for transparency. Swaps incur the hook fee on the paired currency side only, never on transfers involving the pool to prevent settlement errors. This launch implements the proven live pattern from launch #909 for opening and standing fee schedules with treasury funding, providing a fair and transparent mechanism to support the SIMD ecosystem via the swap fees. TESTS AND REVIEW include immutable parameter checks, fee calculation accuracy over the 60-minute schedule, accrual and sweep functionality, interaction correctness with Uniswap v4 swaps on mainnet-fork, and security review confirming no ownership or upgrade paths. 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 swap. - 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).
