New security features: how to verify a call is really from Kraken Support
New security features: how to verify a call is really from Kraken Support

TL;DR

  • Phone callbacks are now verified too. When a Kraken Support agent calls you back on a standard phone line, we flag it as verified in real time; you will see a confirmed banner right in the app, not just for calls made through the app itself.

  • A one-time code proves who you’re talking to. During a callback, ask your agent to read back the verification code shown in your app. If it matches, you know you’re speaking with someone from Kraken.

  • Unverified calls now get a much stronger warning. If we can’t confirm a call is really us, you’ll see a clear message telling you to hang up and report it.

  • It’s live now for everyone, across Consumer Mobile, Pro Mobile, and Krak, including improved detection on Android.

Phone calls are still a scammer’s favorite tool

Scammers know that a confident voice on the phone can be more convincing than any email. Support and impersonation scams typically start the same way: a fraudster calls claiming to be from Kraken, builds a sense of urgency or trust, and then coaches the victim into moving funds, sharing login details, or handing over a two-factor code, all while they’re still on the call.

Why Solana’s Alpenglow Upgrade is More Than Just About Speed
Why Solana’s Alpenglow Upgrade is More Than Just About Speed
  • Alpenglow is the biggest consensus overhaul in Solana’s history. 
  • It is due to roll out in stages between August and October 2026 and cuts transaction finality from roughly 12.8 seconds to 100-150 milliseconds.
  • A new “20+20” security model improves network safety.
  • The minimum profitable stake falls from around 4,850 SOL to roughly 450 SOL, opening validation to smaller operators.

Solana’s Alpenglow upgrade aims to finalise transactions in less time than a webpage takes to load, as part of an extensive upgrade cycle running throughout 2026 that touches everything from block production to user experience.
