Hash Frog: browser-mined PoW NFT + HFROG launch token. Launch kind univ4_hook on Ethereum mainnet, paired with IMD: the factory's standard token and pool with our hook, plus our NFT (with burn vault) and staking contracts. Deploy in the launch, then host a site on the live addresses. No owner, admin, upgrade or pause in our contracts. NFT "Hash Frog" (HASHFROG) - Cap 2,000 ever minted; burned ids never reused. - Mine: keccak256(minter, nonce, lastSeed, blockhash(refBlock)) < target; refBlock within last 64 blocks; lastSeed = previous frog's seed (fixed genesis for #1). - ~60/hour: retarget every 8 mints toward 60 s per mint (max 4x harder / 2x easier). Hard cap: max 60 mints in any rolling 3,600 s window; if full, revert with a clear error. - One per tx, price exactly 0.0019 ETH. Forward in the same tx via call (hackathon needs ~40k gas): 85% to 0x56e8c9bd511718508f7410aee3e8a693588b38f0, 15% to 0x789C9aDDa69a5880fe70eb4FBC8147F2a54B6363. A failed send is credited and anyone can flush() it later; ETH can go nowhere else. - Fully on-chain original frog art (your style), all traits from the seed, a few rares and 1-of-1s; no copies of existing characters or collections. Token "HFROG" (HFROG): the launch's standard token, as the launch deploys it. - Our hook adds 1.5% on buys and 1.5% on sells, taken in IMD, on top of the launch's pool fee. Of every hook fee: 60% to HFROG stakers, 25% to the frog vault, 15% to 0x789C9aDDa69a5880fe70eb4FBC8147F2a54B6363. No anti-snipe. - Frog vault: holds IMD from the hook. buyback(): anyone, at most once per 60 s and at most 100 IMD per call, swaps vault IMD into HFROG through the pool; the HFROG stays in the vault. Burn: a frog holder burns a frog and receives vault HFROG / frogs not yet burned (and the same share of any unswapped IMD). The vault pays out only through burns; nobody can withdraw it. Staking: stake HFROG, earn IMD pro rata (accumulator, claim anytime); fees with no stakers are held for the first stakers; unstake delay 24 h, no rewards during the delay. Site: browser miner (WebGPU, WASM/CPU fallback; hashrate, difficulty, ETA, free slots this hour), mint, gallery from tokenURI, buy/sell HFROG vs IMD, burn (shows what one frog burns into now), buyback, stake/unstake/claim, stats (minted/2,000, vault balance, ETH to hackathon and team, IMD to stakers). Tests: <=2,000 mints; <=60 per 3,600 s; solution bound to minter; reused lastSeed fails; wrong price reverts; 85/15 exact, flush works; burn pays exactly its pro-rata share, vault never negative, no withdrawal; buyback limits hold; hook 1.5% each way split 60/25/15; staking pays out what the hook paid in; nothing moves funds elsewhere. Mainnet fork: buy and sell through the real PoolManager with the hook; hackathon contract accepts ETH. Independent review.
