The fine print
When you tick the box and press Start, this tab runs the open-source RandomX engine (WebAssembly) and sends its work through our bridge to the HashVault pool, logged in with the project’s Monero wallet. Nothing runs before that click, nothing runs in other tabs, and nothing keeps running after Stop or once the tab is closed.
The pool pays the XMR to the project. Miners receive no XMR: they receive $IDLE for the work the pool accepts.
Every hour has a fixed $IDLE budget taken from the published emission schedule (a share of the original supply per day, cut into 24 hours). At the end of the hour, the budget is split between wallets in proportion to the difficulty of the shares the pool accepted from them during that hour.
One wallet can receive at most 10 % of an hourly budget. Capped and unused amounts stay in the project wallet: they are not redistributed or carried over. Amounts round down to whole base units. If the payout wallet runs low, payouts queue and retry after a top-up.
For each accepted share: the Solana address you entered (your worker label), the optional public name, the share difficulty and the time. Share nonces and hashes are not kept. For each payout: the address, the amount and the Solana transaction. These records have no automatic deletion date because they are the payout ledger.
Live hashrate and session counts come from your browser every 10 seconds, expire after 30 seconds and are never used for rewards. Hosting providers and the pool may process connection and IP metadata.
The leaderboard shows shortened addresses, optional public names and accepted work. Anyone can look up any address on the My rewards page. Payout transactions are public on Solana. The address you enter is a label: it does not prove you own it, and a public name is not unique or verified.
Mining uses electricity and can heat, slow or wear your device; laptops on battery drain faster. The value of $IDLE can go to zero and can be lower than your electricity cost. Nothing here is investment advice. Check the official mint before you trade, and check that browser mining is allowed where you live and on the device you use.
Use the miner only on devices you own or are allowed to use, and never embed or run it on someone else’s device without their consent. Automated or abusive use (fake labels at scale, attacks on the bridge or the pool) can be excluded from rewards. The schedule, cap and rules on this page apply as published; any change is announced before it takes effect. The service is provided as is.
