I warned you. With dates. 🧵👇
2026 hardware wallet scoreboard:
• Ledger: reseller devices with a hidden LTE implant that read seeds off the screen. ~$86M–$102M drained per on-chain analysts. Ledger confirmed the implant.
• Coldcard: a 2021 firmware RNG bug. ~1,816 BTC (~$116M) drained per TRM/Galaxy.
• Trezor: a fulfilment partner breach exposed ~14,000 customers' addresses.
• Tangem: an unpatchable laser attack, shown by Ledger Donjon.
• And now Keystone: a website breach exposing names, addresses and order details (no keys, per Keystone).
The same Keystone that called a rival's seed recovery a "fiasco" and told users "Say goodbye to hackers!" 🛡️
The weak link isn't the chip. It's the box, the factory, the reseller and the shipping database.
Pure Wallet: no extra hardware to intercept, implant or ship to your door. Truly offline Bitcoin + EVM on the phone you already own. ISO 27001 & ISO 27003 certified. Post-quantum cryptography.
We believe this is the safest model in self-custody today. Free on iOS & Android. – at Taiwan
Another reason for @PureWalletPlus
We owe you an apology.
On October 20, we detected unauthorized access to our official website. After verifying API activity with Shopify, we confirmed on October 23 that a third party obtained customer shipping information. You trusted us with those details, and we're sorry we didn't keep them safe.
Exposed: names, contact details, shipping addresses, and order details (items and prices).
Not exposed: payment card or bank details, recovery phrases, private keys, or wallet passwords.
We've blocked access, fixed the vulnerability, opened an investigation, and are emailing affected customers.
Scammers may pose as Keystone by phone, text, email, or mail, offering refunds, replacement devices, or "fixes" for your order or address. None of it is from us.
NEVER share your recovery phrase or private keys, and NEVER enter your recovery phrase into a device you didn't order. We will never ask for them. Don't click links in unexpected messages. Type keyst.one yourself.
A detailed report is coming soon.
Until then, trust only our official channels. If anything feels off, email [email protected]. We'd rather hear from you than have you take a chance.
Again, we're truly sorry to everyone affected.

Security theater isn’t enough.
Pure Wallet is built around:
• ISO 27001 & ISO 27003 certified security standards
• Post-quantum cryptography designed for the threat ahead—not just the one behind us
• Truly offline Bitcoin and EVM capability on mobile—no extra hardware required
We believe we’re the only solution right now that combines truly offline BTC with quantum-resistant design at this level.
The recent attacks weren’t about smarter users. They were about trusted channels that weren’t trustworthy.
Own the stack. Own the keys. Stay offline when it matters.
Your crypto. Offline. Your control.

Most “offline” talk still means a hardware signer that has to leave the factory intact.
Pure Wallet is built for truly offline Bitcoin and EVM use—sign and move supported assets without relying on always-on internet, with peer-to-peer paths via QR and Bluetooth.
No gas fees on offline transfers. No waiting on network congestion. Your phone. Your keys. Your control.
Bitcoin. Ethereum / EVM. Offline when you need it.

Pure Wallet puts cold storage on the phone you already own—no extra device to buy, ship, or trust from a reseller.
✅ Hot wallet for daily use
✅ Offline wallet for gas-free, internet-free transfers
🔐 Vault for true cold storage—lifetime access after a free first month, then a one-time $39.95
Keys stay on your device. No cloud. No third-party hardware channel to compromise.
When the industry’s risk is “what’s inside the box,” the answer is: remove the box.

The space just got a hard reminder: if someone can put a chip in the box, they can steal the seed.
Recent reseller-device implants didn’t break a secure element. They watched the screen, captured the recovery phrase, and emptied wallets—cold storage included.
Hardware isn’t “safe” just because it’s hardware. The supply chain is part of the attack surface.
That’s exactly why we built Pure Wallet differently.
