For a full walkthrough with images, here’s our guide to the real tech inside your quantum-secure wallet.

Create a QSafe Wallet

QSafe Wallet offers a smooth and secure onboarding process directly in your browser. Once installed, you’ll be guided step-by-step to either create a new wallet or restore an existing one, with simple instructions and built-in safety checks.

Create a new wallet

Build your quantum-secure identity in four quick steps:

Step 1

Set a Password

Create a strong password to protect your wallet locally.

This password is not recoverable, so be sure to store it somewhere safe.

Step 2

Confirm Password

Re-enter the password to make sure it's correct.

Step 3

Save Your Recovery Phrase

You’ll be given a 12-word mnemonic phrase.

This is your only way to recover your wallet. Write it down and store it offline. QSafe never stores this for you.

Step 4

Verify the Phrase

To confirm you've saved it, QSafe will quiz you (e.g. “What’s the 9th word?”). Once verified, your wallet is ready to use.

Restore an existing wallet

Bringing back a previous QSafe wallet? Just follow these steps:

Step 1

Select Restore Wallet on the welcome screen.

Step 2

Enter your 12-word recovery phrase.

Step 3

Create a new password for this device.

Step 4

Confirm the password and access your wallet.

All your accounts, balances, and history will be restored automatically.

Quranium Chain Transaction Signing

icon

Build the transaction

User enters recipient, amount, and gas fee. Wallet converts values to hex and fetches gas prices from Quranium nodes.

icon

Sign with SLH-DSA

A 49KB+ quantum-safe signature is generated. Your public key is added for Quranium-specific validation.

icon

Structure the transaction

Quranium uses RLP encoding with 7 fields: nonce, gasPrice, gasLimit, to, value, data, signature+publicKey.

icon

Broadcast to network

The signed transaction is sent to the Quranium network.

Quantum-Safe Backup with ML-KEM

QSafe uses ML-KEM encryption and SLH-DSA signatures to keep your wallet backups secure, even in a post-quantum world.

Step 1
Encrypt the backup

Your wallet data is turned into a JSON string, hashed, and encrypted using ML-KEM.

Step 2
Sign the encrypted payload

To verify integrity, the payload is signed with your SLH-DSA key.

Step 3
Store securely in the cloud

The payload and signature are saved to the server under your public key.

Step 4
Restore your backup

To restore, the user provides a valid timestamped signature, and the backup is fetched.

Step 5
Verify ownership & signature

Server checks your SLH-DSA signature before allowing access.

Step 6
Decrypt the backup

Once verified, the shared secret is recovered and used to decrypt.

Done. Your wallet is restored; private, quantum-safe, and fully under your control.

Backup & Recovery

QSafe protects your wallet with quantum-secure backups. Here’s how it works, and how to restore everything if needed.

Restore a wallet

You have two ways to recover your wallet:

Option A: Recover with your phrase
Option B: Restore from backup

That’s it. Your wallet, keys, and settings, fully recovered.
Quantum-safe. Self-sovereign. Ready to go.
