What Ultravein is

Ultravein is an open-source project on Robinhood Chain (chain id 4663). Holders run a virtual VGA from their own terminal and earn a share of public reward pools held by a single smart contract, MiningPool. All code, including the contract, this website and the terminal client, is public under the MIT license at github.com/ultravein/ultravein-protocol.

Stay safe

• Ultravein will never ask for your seed phrase, recovery words or private key: not on this site, not in the terminal, not in a direct message.
• Deploying a rig and linking a terminal are plain-text signatures. Read the text in your wallet before you sign; it always starts with ultravein.
• The only transactions are withdrawing your own rewards and, if you choose, buying a VGA from the shop. Both show the MiningPool contract as the destination.
• Only use links from this site or the official repository. Anyone offering an "airdrop" or "support" that asks you to sign something else is not us.

Terms of use

• The software is provided "as is", without warranty of any kind, as stated in the MIT license.
• Rewards depend on pool balances and on how many rigs are running. Nothing on this site is an offer of investment, a promise of return or financial advice.
• Smart contracts and blockchains carry risk, including bugs, network outages and loss of funds. Use only what you can afford to lose.
• Tokenized stocks are not available to US persons. You are responsible for following the laws of where you live.
• Where this site and the deployed contract differ, the contract wins.
