SIGBRO keeps Ardor accounts safe in the Apple Keychain.
With SIGBRO you can auth and sign in to web UIs that have SIGBRO Auth* integrated, and see your transaction history, NFTs, and token balances. SIGBRO supports local signing of transactions on the Ardor blockchain platform, from multiple accounts, and shows the user the correct tx details before letting the user approve them, so users avoid getting tricked into signing bad transactions if they end up on a phishing website.
SIGBRO can notify the user about transactions in accounts they monitor. Users can subscribe to alerts about incoming/outgoing transactions, forging or bundling rewards, read encrypted messages (the app decrypts them, if the user has reading-rights), and approve transactions in accounts under Account Control.
*) SIGBRO Auth is a passwordless login method. You can contact us for specs and learn how to integrate it into your Ardor app or any other web UI.
