Cubits security cold storage 01

100% cold storage
of user funds

We refuse to compromise when it comes to security, which is why we uphold the gold standard of Bitcoin security and use multi-signature cold storage. Every satoshi deposited with Cubits is placed into offline cold storage, and all funds within hot wallets are Cubits’ own company funds. Additionally, we ensure that physical access to the computing facility and all cold storage hardware is highly restricted. All seeds and data are stored with additional encryption to ensure that in the near-impossible event of stolen hardware, all stored Bitcoin would remain safe and secure.

Access to cold storage
protected by multi-signature technology

All your funds are protected with Bitcoin multi-signature technology. This means our Bitcoin storage and handling protocols have no single point of failure. Each transfer from the cold wallet to the hot wallet requires the presence of at least two management team members, who personally and individually decrypt their seeds on secure hardware and sign the transaction. We’ve carefully designed a system that makes side channel attacks on our hardware and software close to impossible, giving our cold wallet funds the maximum security.

Our hot wallet is used for real-time outgoing Bitcoin operations like buying or withdrawing Bitcoin. Although the wallet is online at all times, the sensitive material is distributed among independent hosting locations which are individually secured and monitored. Just as with the cold wallet, we also employ Bitcoin multi-signature addresses to ensure there is no single point of failure that could expose your funds.

Even though we put great care into designing and maintaining this infrastructure, we are fully aware that by the very nature of a hot wallet we cannot achieve the same level of security as with our cold wallet. So, we’re going to go one step further: we guarantee that the hot wallet will always contain only our own company funds, making your Bitcoin balances perfectly safe even in the event that all of our servers are simultaneously compromised! To ensure this, all deposit addresses are directly issued from the cold wallet so that we are always in complete control of the hot wallet balance.
