Reason 1: No battery.
The implant found in the tampered Ledger devices needed power to send the recovery phrase over the mobile network. It got it from the device itself: the original battery had been replaced with a smaller one that powered both the device and the implant.
The Hashwallet card has no battery. It runs on the energy your phone sends through NFC while you scan it, and that isn't enough to power a hidden SIM.
If you're a Hashwallet user, you may have been wondering whether your Hashwallet is safe. Well, it is. But let's look at how the security works together.
Ledger confirmed that devices sold through a reseller were physically tampered with before reaching buyers. Inside, a hidden circuit board with a microcontroller, an LTE module, and a tiny eSIM had been added. The devices arrived sealed and passed Ledger's authenticity check, and when users set up their wallet, the implant read the 24-word recovery phrase shown on the screen and sent it to the attackers over the mobile network.
This attack doesn't work on Hashwallet, and here's why:
1. No battery. The Hashwallet card has no battery. It runs on the energy your phone sends through NFC while you scan it, which isn't enough to power a hidden implant like the one found in the Ledger devices.
2. There's no casing to hide malicious hardware in.
3. Your keys cannot leave the chip. The Hashwallet firmware has no commands to expose or display keys. Keys are generated or imported inside the chip, and they don't leave it. Since the firmware can't be updated, malicious updates can't add a way out.
4. The card alone doesn't hold complete keys. When you generate or import a seed, Hashwallet automatically creates a cryptographic element that works like a passphrase. It's stored encrypted in the app, so the keys inside the chip aren't complete on their own.
5. Each card has its own encryption. Every card uses a different encryption schema, so breaking one card gives no advantage over the rest. This makes large-scale attacks cumbersome and economically unattractive.

Hardware wallets are moving beyond cold storage.
Our latest research looks at how @era_wallet, @RyderWallet, @hashwallet, @DigitShield_HQ, and @ELLIPAL approach some of the category’s biggest questions:
🔹 How should recovery evolve?
🔹 What must remain clear before approval?
🔹 Where should the security boundary sit?
🔹 What role could AI play?
The approaches differ – and that disagreement may tell us where self-custody is heading next.

Bears and crypto might not be the best combination. HASHWallet has your back and prevents typical mistakes users make on a bad day. Or... a very good one 😉
Adding a new wallet on HASHWallet is quick, right from a seed you already have.
Open your seed screen → tap + → select the asset → Generate wallet → choose the token holder → name your new wallet → scan your card → done.
Here's exactly how 👇
