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.

⚠️ 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.
