12.8s to 150ms finality 🚀

Huge congrats to @anza_xyz and @solana on shipping Alpenglow, and to every validator who made the switch!

Solana fam, next time you send a txn, don’t blink.

[Solana @solana]

Alpenglow is now live on Solana mainnet. ⛰️

Finality just went from ~12.8 seconds to ~150ms.

The biggest consensus upgrade in Solana’s history, built by @anza_xyz.

Your hardware wallet shouldn't need to stay connected to protect your crypto.

With air-gapped QR signing:
→ Review the transaction
→ Sign offline
→ Scan the signed transaction back

No direct USB or Bluetooth signing connection.
Keep your keys offline. Keep control in your hands. 🔐

[Keystone Hardware Wallet @KeystoneWallet]

@HeyTaiZen Sure, sir.

[Keystone Hardware Wallet @KeystoneWallet]

📣 The Ledger supply chain attack is a wake-up call for every hardware wallet maker. Us included.

And we’re treating it like one.

Here’s what that means:
Our team is auditing our entire supply chain, starting with how we vet and manage resellers, and tightening controls wherever this kind of attack could slip through.

On the device side, the Keystone 3 Pro already ships with anti-tamper protection, and we’ll make it even tougher in every device that follows.

Keeping your keys safe is the reason Keystone exists. We’ll work every day to stop attacks like this before they ever reach you.

Huge thanks to the whole Keystone community for your continued support 💙

@Mich_Li Sorry for the inconvenience, fam 💙
Firmware v3.1.4 has a known loading issue, and our team is working on a fix. We’ll release an update as soon as it’s ready. Thanks for your patience!

[Keystone Hardware Wallet @KeystoneWallet]

Your Zcash wallet hands you a fresh receiving address every time. Great for privacy.

But how do you know that address is really yours?

Keystone firmware v3.1.4 lets you check it on your device before you share it.

Update your Keystone 3 Pro and try it out.

Clear-signing isn’t just for experts ⚠️

Small swap or big transfer, you should know exactly what you’re signing.

Start the txn on Nexus, then check every detail on your Keystone screen.

Here’s what that looks like 👇

Fire, floods, faded ink. Paper loses to all three

If your seed phrase lives on paper, so does your Bitcoin.

@dhoneysett shows why metal wins and how Keystone's tablets stack up.

Watch it before you trust paper again:

Clear-signing is for everyone ✨

Firmware v3.1.4 sharpens transaction parsing for SOL and TRX, so you know exactly what you’re signing before you hit confirm.

Wallet setup got smoother too.

Holding SOL or TRX? Update your Keystone today 💪

Any project can call itself "quantum-resistant" today. There's no shared way to check.

The Quantum Alliance launched to fix that, and Business Insider has the story.

We're building open standards and public test criteria for chains, wallets, and infra with @QuantusNetwork, @midnightfdn, @hackenclub, @quipnetwork, @thevault_soft, @PQabelian, @intmaxIO, and @Americanfort_io.

Our CTO, @aaron1sme, will represent Keystone on wallet security and build on existing work toward common specs, from secure elements to recovery flows.

Są portfele sprzętowe i portfele sprzętowe. 🔐

Keystone ma system zabezpieczeń, który reaguje na próbę ingerencji we wnętrze urządzenia. Na wideo możecie zobaczyć, jak działa to w praktyce: po naruszeniu zabezpieczeń portfel staje się bezużyteczny.

@dyw93204672 Keystone’s randomness generation has been verified, with entropy levels of 128 or 256 bits depending on the seed phrase length.

[Keystone Hardware Wallet @KeystoneWallet]

🚨 1,404 Qubic wallets just got drained for about $1.3M.

Older Qubic wallet versions generated seed phrases with weak randomness, and an attacker worked out the keys. Qubic halted the network, and most of the stolen funds are frozen for now.

Why updating the app won't save you:
→ A seed phrase is just a random number written as words.
→ If that number isn't random enough, someone else can regenerate it.
→ The v4.26.4 fix only protects seeds made after the patch.

You're exposed if you made your seed before Oct 18 in any browser on an iPhone or iPad, in Safari on a Mac, or in the iOS app before July 2025.

If that's you, update the Qubic wallet, generate a new seed, and move your funds once the network is back up. Treat the old seed as burned.

For long-term holdings, go further:
→ Get a hardware wallet and generate a fresh seed on the device itself.
→ Write it down, store it somewhere safe offline, and keep it off your phone, your photos, and the cloud.

Keystone builds your seed offline from three separate sources of randomness, plus your own dice rolls if you want.

Security incident update.

Between 23:42 UTC on 17 October and 01:26 UTC on 18 October, an attacker drained 1,404 Qubic wallets, totalling around 2.94 trillion QU.

Here is what happened, what has been done, and what comes next.

Thanks a lot for featuring us, fam! 💙

You’ve done a great job reading between the lines and analyzing the marketing decisions made by industry players.

We’d love to hear your thoughts on one thing: what are your views on the multi-vendor multisig approach? We’d be keen to understand your perspective on it!
