The short answers, with the important caveats.
These answers describe the documented behaviour of this independent project. They are not financial advice and do not replace your own verification.
What is a Monero wallet?+
A Monero wallet manages the keys and information needed to view balances, create addresses and sign transactions on the Monero network. This project is a browser-based hot wallet.
Is this the official Monero wallet?+
No. It is an independent open-source project and is not affiliated with or endorsed by the Monero Project. Verify the source before installing.
Can I restore an existing wallet?+
The documented extension supports restoring from a 25-word recovery phrase by restore height or date, and importing an encrypted backup. Protect the phrase offline.
What can a Monero node see?+
The node can see your IP address, when you sync, the block range you request and whether a transaction was broadcast from your IP. It cannot see your recovery phrase or private keys.
Does it support hardware wallets or dApps?+
No. The documented product does not support hardware wallets, multisig or dApp/website connections.
What happens if I remove the extension?+
Removing the extension or clearing its data can erase saved wallets. Recovery is only possible if you have preserved the 25-word recovery phrase or an appropriate encrypted backup.
Does the website collect wallet secrets?+
No. This marketing site does not have forms for recovery phrases, private keys or wallet passwords. Never provide those secrets to anyone.
