What is a "self-custodial messenger" and what does it mean for me?
A self-custodial messenger means your account, funds, and conversations belong to you — controlled by your recovery phrase, not by a platform.
What “self-custodial” means
In most apps, your account lives on a server. Someone else controls the keys, stores your data, and can, in theory, access it. EXTRA SAFE works differently.
Your identity is created on your device and tied to your wallet. That gives you full ownership of:
- •
Your funds: through self-custody. Your private keys never leave your device.
- •
Your conversations: through E2EE, zero-knowledge encryption by design. Messages are encrypted before they leave your device.
- •
Your account access: through your recovery phrase. The phrase is the account.
What it means for you
- •
You can restore your account on any device at any time
- •
No platform can freeze, delete, or access your account or funds
- •
Your chats are private by architecture – not just policy – it is structurally impossible for us to see the contents of your chats
Ownership is built into how the app works.
