Sead Tool
Your seed phrase is the master key to all your crypto assets. It's also your biggest single point of failure.
Sead Tool transforms your seed phrase into a secure, decentralized backup system giving you full control and peace of mind.Your seed phrase is a single point of failure. Sead makes it your decentralized fortress.
3 steps to eliminate your single point of failure
Sead Tool empowers you to implement an expert-grade security protocol with radical simplicity.
Generate
Enter your seed phrase into the Sead Tool application. The software transforms it into a set of unique QR code fragments according to the rules you define.
Distribute
Store your fragments in different formats and places. Splitting them up is the only way to achieve true decentralization and ensure that a single fragment is useless to an attacker.
Recover
Restore access by scanning fragments offline. Your seed phrase is instantly and securely rebuilt for any wallet.
Why QR codes ?
We use QR codes to eliminate human error : typing long seed phrases is slow and risky. Offline scanning is fast and accurate.
Each QR code contains a unique cryptographic share of your entire phrase, so a single fragment reveals nothing. For extra protection, you can encrypt these shares with your own password.

Why multiple QR codes ?
Sead Tool uses a threshold system. For example, a 3-of-6 setup lets you create 6 fragments but only requires 3 for recovery. You can choose other setups like 2-of-5.
This provides dual protection :

Here’s what people are saying about us
The app is amazing and the QR Code hunt is thrilling! For the product to really gain traction, it needs more advertising and gamification. There’s a lot of projects, and in my opinion, we stick with it for a good reason! Thank you, I enjoyed it and I hope to continue enjoying it while using your products! Have a great day and good luck!
Even though I'm new to the world of crypto, the team succeeded in explaining the problem that they are trying to solve and the solution that they have to offer. Their solution is innovative and solves a problem that has never been dealt with before.
Cryptocurrencies promise freedom in a controlled digital world, but many find them complex. SEAD’s experts—Hugues Dorchy, Olivier Libon, and Jérôme Davidts—offered a clear, accessible coaching session that explained the origins, essence, and functioning of crypto, providing a solid, practical introduction for anyone seeking to understand it.
I just managed to access the seed phrase and the Bitcoin wallet—the system is incredible!
Sead is more than a project, it's above all a team of passionate people. A passion that I was able to feel during the presentation of their project. I was immediately won over by their project. I appreciate the control it gives me over my assets without relying on a third party.
Sead provided me with expert consultancy to help me resolve my issue with my Crypto wallet and gave me educational explanations on the proper use and risks of cryptocurrencies. I recommend them to anyone who would like support, explanations, training, or consultancy to avoid mistakes and the risks of the cryptocurrency world

Frequently asked questions
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 ?
You get a stand-alone software tool with a lifetime personal license. Sead Tool is a one-time purchase that includes:
- Unlimited Use: Secure an unlimited number of seed phrases for any blockchain.
- No Installation: The tool runs directly in your browser offline, like a local webpage. You can use it on a laptop, desktop, or tablet.
- Universal Compatibility: It works with any 12, 18, or 24-word seed phrase from any BIP-39 compatible wallet (Ledger, Trezor, MetaMask, etc.).
You can explore every feature right now with our free online simulator to see exactly how it works before you buy.
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.
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.
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.
