Understanding the threats is the first step to protecting your assets.
Every traditional method of storing your seed phrase has critical vulnerabilities. Here's what you're up against.
Fire, flood, fading ink — a single piece of paper stands between you and total loss. One house fire, one flood, one glass of water and your crypto is permanently inaccessible.
Memorizing 12–24 random words is dangerously unreliable. People forget, misremember, or pass away — taking every penny of their crypto with them, permanently.
Until now, storing digitally meant handing your keys to a third party. Any cloud service, note app, or screenshot puts your seed phrase one breach away from theft.
This is not theoretical. Billions of dollars in crypto are stolen every year because hackers have perfected these attacks. Most victims never saw it coming — and never got their funds back.
Fake MetaMask, fake exchanges, fake airdrops — all designed to trick you into typing your seed phrase into an attacker's website. Billions stolen annually.
Malware silently monitors your clipboard for seed phrases. The moment you copy-paste, your words are sent to an attacker's server.
Compromised hardware wallets, pre-loaded seed phrases, or tampered packaging. If your device was touched before you, your keys may already be exposed.
Cameras, onlookers, or even binoculars. The moment you display your seed phrase on screen or paper, anyone watching can capture it.
No encryption protects against physical threats. Attackers coerce you directly to reveal your seed phrase under duress.
Hardware wallets protect your keys during transactions — but they do nothing to protect your recovery seed phrase. When the device breaks, gets lost, or is stolen, you're right back to the same vulnerability: a piece of paper with 24 words.
Hardware wallets can break, get lost, or be stolen. When that happens, your entire portfolio depends on a single recovery phrase — often stored insecurely.
Your Ledger dies? You need the recovery phrase. But storing that phrase securely is the exact same problem the hardware wallet was supposed to solve.
Pre-configured devices, tampered packaging, counterfeit units sold on secondary markets — you can never be 100% sure your device hasn't been compromised.
Bluetooth, USB, NFC — every connection is an attack surface. Firmware updates can introduce vulnerabilities, and not all wallets are open-source auditable.
CoinSeal eliminates the single point of failure by encrypting your seed phrase with quantum-resistant algorithms — so even if your hardware wallet dies, your backup is secure.

An estimated $100B+ in crypto may be lost to inheritance failures.
Every additional step in your recovery process is a potential failure point.
NIST has published post-quantum encryption standards. The transition is not optional — it's urgent.
CoinSeal uses ML-KEM-768 (CNSA 2.0 compliant) — quantum-resistant by default.
A zero-knowledge, quantum-resistant vault for your crypto seed phrases. Every design decision puts your security first.
CoinSeal combines a proprietary superposition algorithm with post-quantum encryption to protect your seed phrases through three distinct layers.
Your seed phrase is scrambled using our proprietary algorithm. The original order is transformed before leaving your device — making reconstruction impossible without your personal key.
ML-KEM-768 and XChaCha20-Poly1305 protect your scrambled data against both classical and quantum computing threats — CNSA 2.0 compliant.
CoinSeal's servers only ever see double-encrypted gibberish. Your PIN and passphrase never leave your browser — by design, not by policy.
Built from the ground up with a zero-trust architecture. Every design decision prioritizes the security of your seed phrases.
All encryption and decryption happens in your browser. CoinSeal's servers never see your PIN, passphrase, or unencrypted seed phrase — mathematically guaranteed, not promised.
CNSA 2.0 compliant. ML-KEM-768 and XChaCha20-Poly1305 protect your data against both classical and future quantum computing threats.
Double encryption model: your browser encrypts first, then the server wraps with AES-256-GCM. Two fully independent layers of protection on every single vault.
You maintain your vault keys at all times. CoinSeal cannot access, recover, or decrypt your seed phrases — by design, not by policy or promise.
Store your cryptocurrency seed phrases safely with zero-knowledge, quantum-resistant encryption. CoinSeal never sees your original seed phrase — only a scrambled version that only you can reconstruct.
