[SIMD-LAUNCH]
[SIMD-LAUNCH] Token name: SIMDTEST Token symbol: SIMDTEST You are launching SIMDTEST (symbol SIMDTEST), a token on Ethereum paired with IMD using Identity.md's launch.open with an onchain univ4_hook called SIMDTESTHook. The project is a test preset on the SIMD Launchpad featuring anti-snipe and buyback-and-burn mechanics. The total supply is 1,000,000,000 tokens with 18 decimals. The token itself only supports basic transfers with no taxes, limits, pausing, or minting; all mechanics live exclusively in the hook. Supply Distribution: - 80% of the total supply seeds the IMD-SIMDTEST pool. - 10% of supply is sent to the SIMD Hackathon vault at 0x3dd5f73dd1a4e62630fad3909673f130ad429985. - The remaining 10% is reserved outside this scope (e.g., the launcher or other destination as desired). SIMDTESTHook Mechanics: - Triggers on Uniswap v4 hook callbacks involved in token swaps (swap callbacks). - Anti-snipe fee: for the first 10 blocks after the pool opens, an extra fee starts at 30% and linearly decays to 0% at block 10. This fee is deducted from the swap amount. - The anti-snipe fee is not burned or sent elsewhere: it is donated back into the pool's in-range liquidity via PoolManager.donate(), increasing liquidity and reducing slippage. - Buyback-and-burn fee: on every swap, an additional 0.5% fee is charged on top of the pool's default 1.25% fee and the anti-snipe fee if applicable. - The 0.5% buyback fee (taken in the paired currency IMD) accumulates inside SIMDTESTHook. - Anyone can call buybackAndBurn(), which swaps all accumulated paired currency fees for SIMDTEST tokens in the same pool and sends those tokens immediately to the burn address 0x000000000000000000000000000000000000dEaD. Administrability: - The hook has no owner, no pausing ability, no upgradeability, and no fee adjustments after deployment. Testing Instructions: - Verify the anti-snipe fee correctly starts at 30% at pool start and linearly decreases to 0% by block 10. - Confirm the anti-snipe fees are donated correctly into pool liquidity, increasing the pool’s balances. - Check that the 0.5% buyback fee is properly collected in paired currency. - Test buybackAndBurn() swaps accumulated IMD fees into SIMDTEST tokens within the correct pool and burns them. - Confirm no unexpected minting, blacklisting, or owner privileges exist that could trap buyers. Note on Fees: - The pool charge remains 1.25%. - The hook adds up to 30.5% extra fee only during initial anti-snipe period, otherwise only 0.5% extra. - Identity.md's 1% creator fee is handled externally and omitted here. This setup ensures a fair launch and emission control by buyback and burn, while sustaining pool depth through liquidity donation. 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).
