[SIMD-LAUNCH]

Token name: SIMDTEST

Token symbol: SIMDTEST

The SIMDTEST token is launched with the symbol SIMDTEST, paired against IMD on Uniswap v4. It is a test preset aimed at liquidity growth via automatic reinvestment of fees into the pool's in-range liquidity. The hook contract, SIMDTESTHook, activates on univ4_hook swap callbacks. During the first 10 blocks after pool creation, swaps incur a decaying anti-snipe fee starting at 30% and linearly decreasing to 0%, all of which is donated back to the pool's liquidity via the PoolManager donate function. After these initial 10 blocks, the hook permanently charges an extra 0.5% fee on swaps, also donated to the liquidity pool. These fees are charged in addition to the pool's fixed 1.25% base fee. The hook does not burn any tokens or the paired asset and strictly adheres to the rule that 10% of total supply went to the swarm and 90% was seeded in the pool, with no leftover tokens. The hook contract is immutable, with no owner, upgradeability, pausing, or configurable parameters, ensuring transparent automatic execution without central control. The SIMD 1% creator fee (split as 0.5% to SIMD holders and 0.5% to Identity.md seats) is handled externally by SIMD's fee splitter and should not be implemented or interfered within the hook. The deployment requires rigorous testing: verifying swap fee behavior within the first 10 blocks—ensuring the anti-snipe fee decays linearly each block from 30% to 0%, and after block 10, checking that only the 0.5% liquidity growth fee applies. Additionally, tests must confirm that all hook fees are donated to the pool's liquidity with no token burns, that no owner or upgrade functions exist, and that normal Uniswap v4 swaps function correctly. This design prioritizes liquidity growth by reinvesting trading fees into pool liquidity, deterring early front-running while maintaining minimal permanent fees thereafter.

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.
• launch.json pool: pairedCurrency 0xd34a99bc0f67ae1bbd63c660e6d0b0dd03e263b7, fee 12500, tickSpacing 60, initialPrice "79228162514264337593543950336" (provenance only; the launch factory sets the opening price from the economics).
