RULES TO EXPLAIN ON THE PAGE: lock 0.001-1 Sepolia ETH; it opens when Squeektoshi the hamster runs the km you picked (1-100), counted from the moment you lock; breaking early returns 80%, the 20% penalty plus any rewards you had earned go to everyone still holding (burned if nobody is); after 30 days every jar opens anyway; one jar per wallet; no owner, no admin.

PAGE:

• Hero: HAMLOCK. Lock your ETH. It opens when Squeektoshi runs the distance.
• Connect a wallet (injected wallets such as MetaMask/Rabby); prompt to switch to Sepolia. Reading works without a wallet.
• Lock form: distance slider 1-100 km (show the work units = km x 1139, and that a typical active night is about 10 km), amount input 0.001-1 ETH, Lock button.
• My jar: amount, km, progress bar from startWork to targetWork using currentWork() (settled), plus a lighter live overlay from https://api.squeekchain.com/v1/status field measurement.cumulativeWorkUnits labelled "live, not yet settled"; show km = work x 0.878 / 1000; pending reward; deadline countdown; Open button when isOpenable; Break button with a confirm dialog showing the exact 80% refund and the forfeited reward.
• Hamster panel: measurement.coreStatus (SPINNING / IDLE) and rpmMilli / 1000 as rpm from the same API, refreshed every 15 seconds, with a link to https://x.com/squeekchain for the livestream.
• Stats: totalLocked, activeJars, totalPenalties, totalBurned.
• Leaderboard: wallets ranked by kmCompleted, then jarsCompleted, built from Opened events where hamsterRanIt is true; also show jarsBroken as "paper hands".
• Share on X button with prefilled text: "I just trusted my ETH to a hamster. It unlocks when @squeektoshi runs N km. #hamlock" plus the site URL.
• Footer: Sepolia testnet game, no real value, not affiliated with Squeekchain. Links to the contract on Sepolia Etherscan and the GitHub source.

Rules: every number on the page comes from the contract or the Squeekchain API, never hardcoded. If the API is down, show settled data only. Pixel-dark style that echoes a dot-matrix screen, mobile first, fast to load.
