What if someone gets to your Keystone 3 Pro before you do? 👀 You’ve asked us this a lot, so we put it on camera 💥 Watch to the end and share it with anyone who’s asked you the same thing 🫡

Side effects of using a Keystone hardware wallet with the Nexus app 👀 🥶 Your keys stay cold 🛡️ Hackers stay away 🔍 What you see is what you sign ☮️ Life gets a lot less stressful Anyone else experiencing these? 😉

⚠️ If your seed phrase has ever touched an online device, assume it’s compromised. Move to an air-gapped signer like Keystone 🫡
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. 🔐

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.
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.

📣 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 💙

Into @Zcash & on-chain privacy? 🛡️ All it takes: 1. A Keystone 3 Pro 2. Connect to @zodl_app/@vizorwallet 3. Move your $ZEC from CEX to Keystone & shield it. That's it. Full privacy, air-gapped security under your control 🔐
It started 10 years ago a codebase fork of Bitcoin with privacy built into the protocol the first real-world implementation of zero knowledge proofs

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: youtube.com/watch?v=Bk3_XlKM…

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. Read it here 👇 markets.businessinsider.com/…

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.

1/ 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 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 💪

🚨 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.

Ever wondered what happens when someone tries to tamper with a Keystone 3 Pro? You’ll see it today. Stay tuned.

We’re joining @QuantusNetwork’s Quantum Alliance. Our CTO @aaron1sme will represent Keystone on wallet security and build on existing work toward common specs, from secure elements to recovery flows. Post-quantum keys shouldn’t need a different setup for every wallet.
“Post-quantum” is now a marketing buzzword. We’re here to separate the legit tech from the vaporware. Today, ten contributors from across the industry launch the Quantum Alliance. This open standards body will define blockchain quantum readiness. Contributors submit proposals and earn support through evidence and working code. Founding contributors: @YuviLightman, @QuantusNetwork @MehowHacks, @Americanfort_io @HiokiLeona, @intmaxIO @aaron1sme, @KeystoneWallet @SebastienGllmt, @midnightfdn @cadillion and @rcarback, @quipnetwork @PQA_Rich, @PQabelian @bizdevving, @thevault_soft @katina_messinis, @hackenclub thequantuminsider.com/2026/1…

Today leaders from nine blockchain organisations launched the Quantum Alliance, an open standards body working out what "quantum-resistant" should mean for blockchain networks and how such a claim can be verified. The founding contributors come from @QuantusNetwork, Postquant Labs @quipnetwork, @midnightfdn, @KeystoneWallet, @Americanfort_io, @intmaxIO, @PQabelian, @hackenclub and The Vault, and we are glad to take part through our CRO Bryn Bennett. The need is easy to see: in May one index ranked Ethereum second among quantum-prepared networks, while another scorecard, counting only cryptography already in production, gives it an F. The Alliance will publish an open definition of readiness, test criteria any team can run against its own implementation and reference designs for migration, with work starting in four groups on migration, post-quantum zero-knowledge systems, wallet security and cross-chain compatibility. For a custodian this is a practical matter, as the institutions we work with will need to judge the quantum readiness of every network and provider they rely on, ours included, and a shared public standard gives that judgement solid ground as we develop post-quantum custody of our own.

⚠️ If your device connects to the internet, it’s the wrong place for your seed phrase. Switch to an air-gapped signing device like Keystone 3 Pro 🛡️ Don't wait for a year. Do it today & thank us later 🤝

Want to borrow against your Bitcoin without it leaving self-custody? This one’s for you ⚡️ @babylonlabs_io just posted an ARFC on the @aave forum to bring native BTC to Aave V4 as collateral via Trustless Bitcoin Vaults. Read it, verify the details, and share your take 👇
Today, we published an ARFC on the @aave governance forum to propose native Bitcoin to Aave V4 as collateral through Babylon Trustless Bitcoin Vaults (TBV). The proposal includes two new Aave V4 Spokes; Babylon Spoke and BTCVault Swap Spoke for borrowing and liquidation settlement, revenue sharing terms and AAVE, BABY buybacks. If approved and implemented, Bitcoin holders can lock their native Bitcoin on the Bitcoin chain self-custodially, and use it as collateral to borrow supported assets on Aave V4, without wrapping, bridging, tri-party escrow, or sending their Bitcoin to third parties. Risk parameters for both Spokes will be provided by Aave's risk service providers. Subject to Aave governance review and approval. governance.aave.com/t/arfc-o…
