Security notice · Updated October 26, 2026

October 2026: free replacement for OneKey devices bought from CryptoBilis

After Ledger found hardware implants in Ledger devices sold by the reseller CryptoBilis, OneKey ended CryptoBilis’s authorization, paused new resellers and began reviewing existing ones. OneKey says no OneKey user has reported losing funds and does not report finding a tampered OneKey device.

As a precaution, OneKey replaces for free any OneKey model bought from CryptoBilis between 1 March and 12 October 2026, activated or not, with proof of purchase. Apply through OneKey support by 31 December 2026; the old device does not need to be returned.

OneKey’s advice: do not activate an unused CryptoBilis unit. If a device from CryptoBilis already holds funds, move them now to a wallet with a newly generated recovery phrase rather than waiting for the replacement.

This concerns one reseller, not the device design, so it does not change our ratings.

Keycard Shell vs OneKey Pro 2: Frequently Asked Questions

Answers about Keycard Shell vs OneKey Pro 2

Is Keycard Shell better than OneKey Pro 2?

On the numbers, OneKey Pro 2 comes out ahead — 76/100 vs 66/100 — but 'better' isn't quite the right frame. Keycard Shell is more affordable at $129, which matters more for some buyers than overall score does. If overall rating is what you actually weigh first, take OneKey Pro 2. If budget is the constraint that shapes your decision, Keycard Shell is the smarter buy. Either way, both are real hardware wallets — neither is a mistake.

How much do Keycard Shell and OneKey Pro 2 cost?

Keycard Shell costs $129, OneKey Pro 2 costs $299. These are list prices for the standard edition from official manufacturer stores. A few things worth knowing: hardware wallet prices barely move during the year, so 'waiting for a sale' rarely pays off — Black Friday is the one exception, with 10–20% off being typical. Avoid third-party listings even if they're cheaper; the supply chain risk on a tampered device wipes out any savings the first time you load funds. And don't buy a 'used' hardware wallet, ever — even if it claims to be reset.

Is Keycard Shell waterproof?

No — Keycard Shell has no official water or dust resistance rating, so treat it like any other small electronic. A spilled drink or a rainstorm in your jacket pocket is enough to brick it. OneKey Pro 2, by contrast, carries an IP56 rating, which means it's tested against dust and pressurized water — that's the device you'd actually take camping or to a beach. For most people, water resistance isn't a deciding factor, but it matters if you travel light or carry your wallet daily.

Which wallet is better for DeFi and Web3: Keycard Shell or OneKey Pro 2?

Keycard Shell — and the gap is bigger than the spec sheets make it look. Keycard Shell has WalletConnect built in, which means you sign DeFi transactions directly from a hardware wallet without exposing keys to a hot wallet. OneKey Pro 2 can technically work with DeFi via third-party software, but every extra step is one more place an attacker can intercept the transaction you're approving. If you're going to be clicking 'Sign' on smart contracts more than once a month, the difference compounds fast.

Where to buy Keycard Shell at the best price?

Always buy Keycard Shell from the official Keycard store — never from Amazon, eBay, or third-party marketplaces, even if the price looks better. Hardware wallets have been physically tampered with in the supply chain before (compromised devices shipped to unsuspecting buyers, then drained the moment funds were loaded). Buying direct from Keycard gets you a sealed unit with full warranty, firmware integrity, and a clean chain of custody. Free shipping and occasional discounts at the source make the price difference negligible anyway.

Do Keycard Shell and OneKey Pro 2 come with a warranty?

Yes — both ship with a manufacturer warranty (typically 1–2 years) when bought from the official store. That said, a hardware wallet warranty is mostly about hardware defects, not lost funds. If the device fails, the manufacturer will replace it — but your seed phrase or backup cards are what actually restore your crypto onto the new device. The warranty is real but secondary; what protects your funds is your backup discipline, not a piece of paper from {{wallet1}} or {{wallet2}}.
