Why Sanctum
A wallet that gets out of your way.
Multi-chain by default
Six chains in one place. No juggling apps, no managing multiple seed phrases, no switching networks.
Encrypted on your device
Your wallet is unlocked with a password only you know. AES-GCM encryption with 250,000-iteration key derivation.
Built for clarity
Every send shows you the recipient amount, the fee, and the total — before you sign. No hidden cuts.
Works anywhere
Any browser. Any device. Install as an app on your phone or desktop with a single tap.
How it works
Three steps to your first transaction.
Create your wallet
Open Sanctum, pick a password. Your seed phrase is generated on your device and encrypted before storage.
Receive crypto
Each chain gives you a unique address. Send some BTC, ETH, SOL, DOT — or a stablecoin — to start.
Send anywhere
Type the recipient address, the amount, your password. Sanctum signs and broadcasts. Done in seconds.
Built carefully
Security you can read about, not just believe in.
We use standard, well-documented cryptography. The same primitives banks use, applied with the same care.
Try it now- On-device encryption
AES-GCM with PBKDF2-SHA256, 250,000 iterations. Your password derives the key.

A flat service fee per transaction, always shown before signing. No hidden cuts.
