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.

01

Create your wallet

Open Sanctum, pick a password. Your seed phrase is generated on your device and encrypted before storage.

02

Receive crypto

Each chain gives you a unique address. Send some BTC, ETH, SOL, DOT — or a stablecoin — to start.

03

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.

  • Address validation

    Every recipient address is checked against each chain's format before you can hit send.

  • Transparent fees

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