01
Choose a separate Android phone
Do not use the phone you carry every day. Choose a device that can remain dedicated exclusively to Seeder.
Seeder before the hardware
Turn a dedicated Android phone into an offline Seeder environment.
The dedicated Seeder hardware is designed to be completely offline. It will have no Wi-Fi, Bluetooth, NFC, mobile network or data connector. Until that hardware is available, a separate Android phone can be configured to follow the same fundamental isolation principle.
Important
Do not use your everyday phone for your seed.
Your everyday phone is designed to stay connected. It runs many applications and communicates through Wi-Fi, mobile networks, Bluetooth and other services. A device used for sensitive recovery information should be treated very differently.
The principle
Seeder is designed to stay offline.
The future Seeder hardware is being designed as a dedicated device for working with sensitive recovery information in an isolated environment.
It is not intended to behave like a smartphone, computer or hardware wallet that regularly connects to other systems. Communication interfaces are intentionally excluded from the design.
No Wi-Fi
No wireless network connection.
No Bluetooth
No Bluetooth communication interface.
No NFC
No near-field wireless communication.
No mobile network
No SIM card or cellular connection.
No data connector
No USB or similar communication port.
Battery powered
Designed to operate independently, much like a calculator.
Until the hardware is ready
Use a separate Android phone only for Seeder.
The physical Seeder does not yet exist. We do not want users to wait for the hardware before they can start using the Seeder workflow.
A dedicated Android phone can therefore be configured as a temporary offline environment for Seeder. The goal is to remove the normal connected-phone behaviour and keep the device isolated during sensitive operations.
Minimum requirements
It does not need to be a new or expensive phone.
A spare or older Android phone is sufficient as long as it meets the minimum requirements and can be dedicated exclusively to Seeder.

How to create your dedicated offline phone.
02
Factory-reset the device
Start from a clean installation and remove the previous user's applications, accounts and configuration.
03
Install only the Seeder app
Keep the device focused on a single purpose. Do not use it for email, social media, browsing, games or other everyday applications.
04
Complete the Seeder security checklist
Seeder checks the device configuration before the sensitive workflow begins and shows which connectivity settings still need attention.
05
Disable connectivity
Keep Wi-Fi, Bluetooth, NFC, mobile networking and other communication services disabled. Do not insert a SIM card into the dedicated device.
06
Keep it offline
Once configured for Seeder, the recommended approach is to keep the phone permanently disconnected and use it only for the intended offline workflow.
Before working with your seed
Seeder checks the environment first.
The application starts with a security checklist designed to help users confirm that the phone is configured as an offline device.
This is especially important for users who are not security specialists. Instead of expecting the user to remember every setting, Seeder provides a clear list of conditions that should be satisfied before proceeding.

Dedicated Seeder use
Why a dedicated phone?
Two phones can have completely different roles.
Designed to stay connected.
- Wi-Fi and mobile internet
- Multiple applications
- Email and messaging
- Cloud services
- Bluetooth and NFC
- Daily browsing and communication
VS
Designed to remain isolated.
- Factory-reset before use
- Seeder app only
- No SIM card
- Wi-Fi disabled
- Bluetooth and NFC disabled
- Kept offline after configuration
The future hardware
Explore Seeder hardware
The same principle, enforced by hardware.
A dedicated Android phone achieves isolation mainly through configuration. The future Seeder hardware is intended to go further: communication interfaces such as Wi-Fi, Bluetooth, NFC and cellular networking will not simply be switched off. They will not be part of the device.
This is the security philosophy behind Seeder: minimize unnecessary communication paths around the environment where sensitive recovery information is handled.
Important security principle
Keeping a dedicated device offline significantly reduces its exposure to normal online activity and remote attack paths. No configuration can guarantee absolute security, so physical access, device integrity and careful handling of recovery information remain important.
