All bitcoin deposits go to our online hot wallets, and are then moved to our offline multi sig cold wallets every evening.
Vaultoro follows the state of the art in bitcoin security standards. Our cold wallets are stored offline and are safe from inside attacks by making sure all spending is regulated by utilising multi signature wallets.
To keep the liquidity and convenience of letting members withdraw their coins as soon as they are requested a minimum amount of funds are stored on a hot wallet (connected to the internet). This wallet is stored on a completely independent server from our trading engine
All paper wallet backups are multi sig and each paper needed to recreate the wallet is password protected.
