Got a ForgeBox? You can test the Zcash Ironwood testnet right now 👇 ① Head to: github.com/KeystoneHQ/key… ② Switch to the zcash-upstream branch (Ironwood testnet support included) ③ Follow the firmware build guide → flash your test firmware ⚠️ Note: Self-built firmware carries no official signature — Stricyly for ForgeBox only. Not installable on Keystone 3 Pro. Not a dev? Official firmware drops after testnet goes live. Worth the wait 🙌

Zcash Ironwood testnet is live 🎉 Devs were already signing 11+ txs with one QR on ForgeBox before the launch — a Zcash testnet record. The community didn't wait. Neither should you. Build with ForgeBox: keyst.one/shop/products/…

Your $ZEC privacy means nothing if it's sitting on an exchange. @CryptoHayes said it. Shielded cold storage is the only reasonable move 🛡️ Get @zodl_app + @KeystoneWallet & shield your $ZEC. That's it. Tag the ZEC holder who still needs to hear this 👇

If cross-chain swaps still stress you out, you haven't tried the right setup 🔥 With Nexus app + Keystone 3 Pro, all you have to do is: Connect → Pick tokens → Review → Sign. No bridges. No blind signing. No unwanted risk. Be honest: Who else has been sleeping on this? 👇

⚠️ Most wallet drains don't start with a hack. They start with a permission you forgot you gave. A trader lost $999,999 USDT yesterday because of one token approval that granted unlimited access. The attacker's script swept the exact remaining balance and left. Clean. Automated. The dangerous moment never felt dangerous. A routine dApp interaction. A quick confirmation. Done. This is how approval phishing works, and why the habits around it matter more than most people realise. Before you sign any approval, read what it's asking for. Set it to the exact amount the transaction needs. Never unlimited. Beyond that: → Revoke old approvals regularly. @RevokeCash, make it easy. → Use a burner wallet with low funds for new or unfamiliar dApps. Keep your main holdings separate. → Distrust urgency. Countdowns and "limited windows" are pressure tactics, not features. Security isn't supposed to be fast. Fast is how you lose a million dollars to a script.

@Hornan7 @HolgerCardano24 @phil_uplc We actually improved it a long time ago. If you are still facing poor battery life, follow this: → Use a 5V1A or 2A power adaptor → Lower the device brightness → Lock the device as soon as the usage is complete → Turn on the auto shutdown function x.com/KeystoneWallet…

Yes, yes, yes, and fking yes. This here, as described by @phil_uplc, is one of the most reliable and safest method, and I strongly recommend you guys use it for everything Cardano-related. Here is a nice tutorial to start with: developers.cardano.org/docs/operators…

Hardware wallets are, for the most part, one of the biggest psyops of this entire industry, and widely recognized as bad opsec by security researchers. The mailing and order lists for hardware wallets are some of the most repeatedly hacked and leaked datasets, appearing on blackhat forms year after year. Mailing addresses, names, emails, all of which are perfectly filtered for known value targets. A $300 laptop with no internet hardware is significantly less likely to get you wrench attacked, or get your root keys rugged by an HW wallet backdoor. Also, for the vast majority of users, a hardware wallet won’t save you if your web-wallet is compromised. You would have to review the entire transaction on the 1 by 1 inch hw wallet screen, where most people look at the wallet summary. You’d have to double check every script hash, every destination address of every transaction you sign. In-practice, the number of people who do this approaches zero.

⚠️ A single URL click can hand full control of your Android to an attacker. Meet IonStack — a full-chain browser-to-kernel exploit using two 0-day vulnerabilities, affecting Firefox before v151.0.2 and Linux kernels for 15 years. One malicious link. Your phone, their hands. This is the moment to ask: where do your keys live? Your seed phrase on a phone or PC is one exploit away from being gone. Keystone 3 Pro keeps your seed phrase completely offline, generating and securing it in isolation from every internet-connected device that can be compromised. Even if your phone gets hit, your keys stay safe. Every transaction is verified on a tamper-proof screen, so you always see exactly what you're signing. If you're still on a hot wallet, now's the time to move.
Nebula Security@nebusecurity

Nebula Security is now backed by Y Combinator. We’re celebrating by bringing you the world’s first Android 17 root demo — “IonStack”, a url click can let attacker fully control your phone. This is not only an Android root demo. We’re bringing you a full chain browser-to-kernel exploit with two 0-day vulnerabilities affecting Firefox before v151.0.2 and all Linux distros in 15 years. "IonStack" demonstrates how bad actors can control your phone by sending a malicious URL, but good news, Nebula Security found it before attackers do. Both 0-day were found by our code scanning agent, VEGA, overshadowing any vulnerabilities found by Mythos or any scanner you name it. VEGA has demonstrated its extraordinary capability in finding critical bugs in the world’s most complicated software: operating systems and browsers. It can spot the same vulnerabilities in your codebase too. VEGA support full scan and incremental scan that can integrated into your CI/CD flow. We launched VEGA within YC companies and received overwhelmingly positive feedback. Now it is open to all enterprise customers in private beta. Book a demo with us: nebusec.ai/book-a-demo

Keystone 3 Pro, OneKey Classic 1S czy Ledger Nano – który portfel sprzętowy naprawdę warto wybrać w 2026? 🤔 Wrzuciłem właśnie mega konkretny artykuł, w którym: porównujemy bezpieczeństwo (secure elementy, air‑gap, open‑source) sprawdzamy wygodę użycia (ekran, łączność, integracje z Metamask / DeFi) omawiamy dla kogo jest każdy portfel – long‑term hodler, DeFi‑degenerat, czy totalny początkujący Jeśli: trzymasz krypto na giełdach, zastanawiasz się nad pierwszym hardware walletem, albo myślisz o zmianie sprzętu na coś „pancerniejszego” – to ten tekst rozwieje sporo dylematów.

I have both The problem with keystone is that I always find it out of charge, even when I'm 100% sure it is turned off when I'm done using it I never experienced "battery charging problems" with ledger, not sure what you are talking about My problem with Ledger is that it is not fully open source I would say Trezor is the best of both worlds, but Trezor basically doesn't work if you don't have their desktop app open (which is open source, but still annoying) and afaik only eternl supports it

Not an ambassador or any relations, but get a @KeystoneWallet for your ADA - the user experience is much better than Ledger and also I don't get a message about battery charging problems every time I use it. If you don't have that kinda money, get a Ledger Nano S.

⚠️Ctrl Wallet is shutting down. From August 3, all functions - transfers, swaps, dApp connections- will be disabled. The shutdown follows a security vulnerability discovered on June 23, targeting Cardano-related wallets on the platform. If you're a Ctrl Wallet user right now, this is stressful, and the clock is ticking. We hope your funds are still safe 💙 Before you do anything else, be aware of what happens during shutdowns like this: → Scammers are already circulating — fake migration rewards, fake support agents asking for recovery phrases. → Ctrl Wallet confirmed: there is no CTRL token, no airdrop, no compensation program. Anyone claiming otherwise is lying to you. Here's how to migrate safely: → Do not import your Ctrl Wallet recovery phrase into a new wallet. If the phrase was ever generated or transmitted online, it may already be compromised — carrying it forward carries the risk with it. → Instead, set up a fresh wallet that generates a brand-new seed phrase in a fully offline environment. Transfer your assets to that new address. A hardware wallet like Keystone 3 Pro does exactly this — new keys, generated by a Secure Element's TRNG, never touch your device or the internet. You've already been through enough. Make sure your next wallet is the last one you'll ever have to migrate away from 🤝

BREAKING: If you travel with crypto, read this! There are now several so called 1st world places where you can be legally forced to hand over your phone or hardware wallet and be made to unlock everything, including your wallet app. So what do you do in that situation? That’s exactly the kind of scenario we build for. Few years ago, we’ve seen cases where people were forced to open their wallet apps at airports or at police stations. To deal with this, we built Unstoppable duress mode. - It lets you set up multiple unlock PINs. Each PIN opens a selected set of wallets. Only one master PIN opens everything. - Undetectable inside the app - no way to know if it’s enabled • unlimited number of PINs Stay Safe!
