Frequently asked questions
What differenciates Sead Safe from a standard cloud storage?
Standard cloud services store your files on centralized, always-online servers, creating a single target for hackers. Sead Safe provides superior security through two key differences:
1) Decentralized Storage: Your encrypted files are stored on a peer-to-peer network with no single point of failure.
2) Cold Key Storage: Your encryption key is kept completely offline in a Hardware Security Module (HSM), making it immune to online threats.
Can I store one of my QR code fragments in Sead Safe ?
Yes. Storing one encrypted fragment in Sead Safe is an excellent way to add digital and geographic redundancy to your backup plan.
Because Sead Safe is a secure cold storage vault, it provides a robust environment for one piece of your backup. However, remember the golden rule: never store all your fragments in the same place or format.
Is Sead Tool a replacement for my hardware wallet?
No, they are designed to work together for maximum security. A hardware wallet secures your daily transactions by signing them offline (it’s your “pen”).
Sead Tool secures your ultimate backup : the seed phrase itself (it protects the “master key to your vault”).
Sead Tool is not a wallet : it has no keys and does not connect to the blockchain. Its sole purpose is to run completely offline to secure your master key, complementing the security your hardware wallet provides.
What do I get when I purchase Sead Tool ?
A stand-alone software tool with a lifetime personal license.
Includes:
- Unlimited use: secure unlimited seed phrases for any blockchain.
- No installation: runs offline in your browser.
- Universal compatibility: works with any 12, 18, or 24-word BIP-39 seed phrase.
Do I need to trust the Sead company for this to work ?
No. The protocol is designed around the principle of zero trust. Once you have the software, you have zero dependency on our company or our servers.
The entire process runs offline on your machine.We will never access your QR codes, your seed phrase, nor know if, when, or how you use Sead Tool. Your security is entirely in your hands, which is the ultimate guarantee of sovereignty.
What should I do to ensure I use Sead Tool securely?
Sead Tool is designed to be secure for everyone. The core of its security is that it runs completely offline. By disconnecting your computer from the internet before you start, you create a secure, isolated environment that eliminates any risk from online threats.
For this reason, using a trusted, malware-free personal computer is a fundamentally secure and sufficient method for the vast majority of users.
For users seeking to eliminate even the most theoretical risks, such as a pre-existing compromise on the device itself, running Sead Tool on a dedicated air-gapped machine or from a temporary operating system (like Tails) offers an additional layer of protection. These methods ensure that absolutely no trace of the operation is left behind.
I keep my crypto on an exchange (like Binance or Coinbase). Can I use Sead Tool ?
When you keep your crypto on an exchange, you don't have a seed phrase because the exchange controls the master keys. Sead Tool cannot be used in this context. You do not actually own it, you are trusting the exchange to hold it for you. This is known as a custodial setup.
While convenient, this model exposes you to critical risks: the exchange can be hacked, can freeze your assets, or can go bankrupt. This is the origin of the core crypto principle: "not your keys, not your crypto."
However, it is always time for you to create your own personal hardware wallet which gives you a seed phrase. Sead then allows you to secure that seed phrase in a way that is truly decentralized and sovereign, ensuring that you will always be in control of your assets.
