Your $ZEC security shouldn't depend on which device you grabbed today.
📱 Mobile? iOS & Android.
🖥️ Desktop? macOS, Windows & Linux.
Vizor + Keystone keep the same air-gapped, privacy-first layer no matter which screen you're on.
Mobile or desktop — which is your $ZEC setup?
The way Zcash was meant to feel.
Now available on iOS and Android.

🎲 Generated your 24-word seed phrase without tracking your dice roll count? You may have 24 words, but not the 24-word security.
Keystone's latest firmware closes that gap 🔐
The old flow: roll until you've got enough numbers, fill in your words, done.
But word count and entropy aren't the same thing — and most implementations never check whether the second one is actually there.
So now:
🔐 12-word phrase → minimum 50 dice rolls
🔐 24-word phrase → minimum 100 dice rolls
The math behind it:
A standard six-sided die gives you ~2.58 bits of entropy per roll.
50 rolls ≈ 129 bits → matches the 128-bit security a 12-word phrase needs.
100 rolls ≈ 258 bits → matches the 256-bit security a 24-word phrase needs.
Roll only 50 times and force a 24-word phrase anyway, and the math doesn't care how many words show up on screen: you're carrying 12-word entropy in 24-word packaging ⚠️
That's not just weaker security — it's worse. It's security you believe is stronger than it is.
Which is exactly why Keystone now hides the 24-word option entirely until you've logged 100 rolls. Not added friction. A refusal to let your phrase lie to you about what it can withstand.
24 words should mean 256 bits of real security — not 256 bits of false confidence. 🛡️

🚨 AscendEX users have spent over a week waiting on withdrawals — no explanation, no word from the team.
@zachxbt flagged it days ago; still silence.
We feel for everyone caught in this.
It's also a hard reminder ⚠️
If you don't hold your keys, you don't hold your crypto.
I recommend your team answers the following questions for the community:
1) Why are AscendEX users reporting delayed or incomplete withdrawals?
2) Why do the AscendEX hot wallets currently not have any liquid assets?
No one should deposit funds to this CEX.

🏆 World Cup season has everyone making predictions.
Scores. Odds. Champions.
But on prediction markets, the biggest risk may not be guessing wrong.
It may be what your wallet is actually signing ⚠️
Polymarket’s frontend was compromised, leading to asset losses for users.
Attackers poisoned the frontend through a third-party supplier and quietly swapped a “normal” transaction into a wallet-draining one 💀
That’s the danger of supply chain attacks:
→ Hackers don’t need to attack your wallet directly.
→ They can compromise the website, plugin, or frontend you already trust.
→ Gitcoin and Yield Yak have faced similar frontend trust-chain failures before.
The fix: stop blindly trusting online screens.
A hardware wallet parses transactions offline and shows the real details on its own trusted display.
The frontend can lie. But your hardware wallet screen shouldn’t.
Don’t just predict the winner. Verify what you sign.
This morning we discovered a 3rd party vendor had been compromised, injecting a malicious script into our frontend for some users. We've contained it & removed the affected dependency. We're contacting impacted users & refunding them in full.

Great news for all Solana devs 🎉
Our Solana CLI support PR has officially been merged into the @anza_xyz Agave main repository.
Getting from submission to merge took several rounds of review, code adjustments, and security tightening.
For Keystone, speed matters, but security always matters more.
We'll be rolling out firmware updates soon, so developers can entrust final signature confirmation to hardware wallets in CLI, scripts, automation, and even AI Agent scenarios.
Thanks to our Solana community for your continual support and patience!
Tag a Solana dev who needs to see this before the official launch 👇
Solana CLI support is almost there 🙏
🟪🟪🟪🟪🟪🟪🟪🟪🟪🟥 90%
Based on the earlier feedback from @anza_xyz, we have refined our CLI integration and are now in the final stretch of review.
Once it is done, we will test carefully with the Anza team to make sure everything lands properly.
Thanks a lot to our Solana community for your continual support and patience 💜

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.

⚠️ The recent SecondFi/Yoroi exploit didn't begin when users clicked "Send."
It began the moment some wallets were created.
Weak entropy can produce predictable private keys. Once that happens, every address and every future transaction inherits the same risk.
Software wallets depend on the host device's CSPRNG for randomness.
Hardware wallets like Keystone generate entropy inside the device with a dedicated TRNG, isolating private key generation from malware and compromised operating systems with boosted randomness.
Self-custody starts with the very first random bit.
Get a hardware wallet and generate fresh seed phrases to secure your long-term assets.

No better time to buy a @KeystoneWallet than the present.
Will make you completely immune to most wallet vulnerabilities.
Also their unwavering support for Cardano deserves massive respect IMHO.
1/ Most Cardano holders face a choice: convenient software wallets OR secure hardware wallets with poor ADA support.
Because hardware wallets treated Cardano as an afterthought.
We took it as a priority.
Here's how we became the go-to hardware wallet for ADA holders 👇

🚨 Never hold large amounts of assets on a hot wallet.
Yesterday, SecondFi (formerly Yoroi, a long-trusted Cardano self-custody wallet) confirmed a breach: ~374 wallets drained, 16M ADA confirmed gone.
Luckily, the team has taken emergency measures to secure users' funds and is working to ensure all assets are returned to affected users as soon as possible.
How did this incident happen? These users held their own keys.
What reportedly failed was key generation itself — weak randomness made private keys guessable.
That's the gap a hardware wallet closes.
Keystone 3 Pro generates keys inside an offline secure chip with a hardware RNG — immune to online attacks by design.
Stronger the randomness = stronger the security.
To those affected: we hope for a fast, fair resolution 💙
As per our previous post:
nitter.app/secondfiapp/status/206…
We have identified the root cause and have since rolled out a patch for all unaffected wallets. This will allow us to resume normal operations soon.
-----
Regarding affected wallets, 4 distinct draining events occurred. 3 were executed by external threat actors, resulting in a loss of ~16m ADA across 374 addresses.
To prevent total loss during the active exploit, emergency rescue measures were triggered to secure the available ~129m ADA and continues to be routed to an independent, qualified third-party custodian, where they are held securely for the benefit of the affected wallet addresses.
An external accounting firm has been engaged for a special audit to independently verify those holdings.
We are working to facilitate the verification process so users can claim back their assets safely. Affected users should submit their claim at support.secondfi.io
We take this incident seriously and are working to ensure all assets are returned to affected users as soon as possible.
As stated, we have identified the root cause, it is at the address level. Please DO NOT RESTORE your recovery phrase into another Cardano wallet, this does not mitigate the security risk. The security risk occurs when an affected user signs a transaction.
Further explanation to follow.

⚠️ If you spot any GTA 6 early access for crypto payments, treat it as a red flag 🚩
Here's why:
GTA 6 is in the pre-order stage. There is no early access, and Rockstar isn't selling any.
What you're looking at is a payment page dressed up as a launch page: neon Vice City art, manufactured urgency, fake VIP language, zero product behind the button.
- Pay $250 in BTC, USDT, or ETH.
- Paste a transaction ID.
- Hit download. Get nothing.
No game, no refund, no chargeback.
Once that payment lands, there's no bank to call and no dispute window to open. That's not incidental. It's why scammers ask for it.
GTA 6 launches Nov 19.
Official pre-orders start June 25 via Rockstar's channels only.
Scarcity + urgency + crypto-only payment is the pattern. Learn it once, recognize it everywhere.
Always verify the source before you take the call.
Cybercriminals are launching fake GTA 6 pre-order sites offering early access for crypto payments.
Scammers are using the hype around one of the biggest game launches ever to lure players into handing over personal information, downloading malicious files, and losing money.
