See It In Action
A beautiful, intuitive interface designed for simplicity
20% of all Bitcoin—$250 billion—is permanently lost due to failed backups.
Q-Ledger offers quantum-safe seed phrase backup that lasts forever, for a one-time fee.
— Jameson Lopp"There are a million ways to back up a seed phrase.
Nearly all of them have flaws."
Hardware wallets protect keys from online attacks but don't solve backup—they relocate it. You've moved from digital vulnerability to physical vulnerability.
We built Q-Ledger to change that.
Back up your first seed phrase in 30 seconds
MetaMask, Trust Wallet, Coinbase, hardware wallet seed phrases. Auto-detects any format.
Apple X-Wing / ML-KEM-768 encryption on your device. Q-Ledger never sees your keys.
One-time payment, permanent storage. Thousands of global nodes. Survives if Q-Ledger shuts down.
Decrypt on iOS with Face ID. Pro version: platform-independent recovery on any device.

The only quantum-safe seed phrase backup solution
No subscriptions. Pay once, store forever.
Your seed phrase backup is protected against future quantum threats.
No physical seed phrase backup to lose, burn, or flood.
Encrypted on-device. Q-Ledger never sees your seed phrases—not even the developer.
Pro: Recover on any platform with GitHub scripts.
Documented encryption. No vendor lock-in.
Works with Inheritor app for digital estate planning.
No email, no registration. True privacy.
Mathematically impossible. Your seed phrases are encrypted on your device before they ever leave your iPhone. Q-Ledger—the app, the company, the developer—never sees your unencrypted data.
The encrypted data goes directly to Arweave's public blockchain. There are no private servers to hack, no employee databases to breach, no API to intercept. Even if someone compromised Q-Ledger entirely, they'd get nothing but unreadable encrypted blobs.
Verify it yourself →
Your encrypted seed phrase backup is publicly visible on Arweave but unreadable without your encryption keys. No private servers to hack, no employees with access—security you can verify.
Q-Ledger uses X-Wing—Apple's quantum-resistant encryption algorithm in iOS 26, built on NIST-standardized ML-KEM-768. While AES-256 remains quantum-safe, the key encapsulation used by traditional backups (RSA, ECDH) is vulnerable to quantum attack.
Since Arweave stores data permanently, Q-Ledger protects against "harvest now, decrypt later" attacks—where adversaries collect encrypted backups today to crack the key encapsulation in the future.
"Think of it like a safe in a public square: everyone can see the safe, but only you have the combination."
Encrypted before leaving your iPhone. Q-Ledger never sees your seed phrases.
Thousands of independent global nodes. Designed to preserve data for 200+ years.
One-time payment. No credit card expiration, no service interruption. Forever.
Works even if Q-Ledger disappears. Pro users can recover keys on any platform using public domain scripts.
